An All-Female Crew Sailed 1,000 Miles in a Traditional Voyaging Canoe to Help Save Humpback Whales

The Hinemoana Halo Waka Moana Initiative recruited 12 crew members from the Cook Islands, New Zealand, Samoa and Tonga. Tee Wells “My people are called the whale riders,” says Māori conservationist Mere Takoko. Whales not only hold cultural and spiritual significance for the Māori, the Indigenous Polynesian people of New Zealand, but they are also often seen as ancestors. “Whales symbolize strength, wisdom and resilience, and they are deeply respected as guardians of the ocean,” says Takoko. Each year in June and July, humpback whales will pass New Zealand as they migrate north from Antarctica to the warmer waters of Tonga to mate, give birth and nurse their calves. They will stay there until October before they return south. The humpback population that uses New Zealand’s waters once stood at 20,000, but whaling at the turn of the century saw it drop to a few hundred. Since New Zealand whalers harpooned their last whale in 1964, it has steadily risen to 10,000. As a keystone species, they play a large part in the ecosystem. The nutrients they release fertilize a food web.

Steve Woods Photography/Getty Images “My community would see them more regularly when I was younger,” says Takoko, a Gisborne resident who is now in her 40s. “It’s very difficult to see them now, as they don’t come as close to the coast. The migratory patterns have been changing.” In 2023, Takoko was part of a team who helped bring together an all-female Pacific crew, which would sail 1,000 miles along the humpback highway from New Zealand to Tonga to help raise awareness of the plight of the whales. Along the way, the Hinemoana Halo Waka Moana Initiative crew would collect environmental DNA (eDNA) data, namely mucus, larvae, feces or skin cells, which researchers could then use to confirm what species are present or are missing from the water. The Hinemoana Halo Waka Moana Initiative recruited 12 crew members from the Cook Islands, New Zealand, Samoa and Tonga. It included veteran sailors, such as Aunofo Havea, the first Tongan woman licensed as a sea captain, and Fealofani Bruun, the first Samoan woman to qualify as a yacht master, as well as a new generation of voyagers. The youngest crew member was 14-year-old Ana Ngamoki from the Te Whānau a Apanui iwi (tribe) in New Zealand, which partnered with the expedition. The team knew that if this marine conservation project were to be truly Indigenous, it would need to feature a waka hourua. The traditional, wooden, double-hulled ocean-going canoe typically has two sails and measures nearly 60 feet long. Polynesians have used the vessels for voyaging for thousands of years. “The voyaging canoes are the heartbeat of Polynesian culture; they are really what helped us to connect deeply with nature,” says Takoko. “From the understanding of the movement of the tides, to the stars and the winds, we can’t really talk about ocean conservation in a way that’s truly authentically Polynesian-led without including waka hourua.” While the journey’s aim was to help save the whales, it would also help heal, in some small part, one country’s voyaging history. The history of voyaging in New Zealand The first people to arrive in New Zealand are thought to have traveled from Hawaiki (Polynesia) between 1200 and 1300 C.E. They navigated the ocean by the tides, moon and stars. “They were oceanic people. The ocean is their highway—it’s not a barrier,” says Lisa Matisoo-Smith, an anthropologist at the University of Otago in New Zealand, who is not involved with the project. Early New Zealanders would make a very systematic exploration of the Pacific. Using the consistency of the trade winds, they would sail from west to east across the ocean. While voyaging was male-dominated, if better land were found, women and children would also make the journey to set up new communities. “Routes [between the new land and homeland] were maintained until the new society was established and complicated enough politically that those links weren’t useful anymore,” says Matisoo-Smith. The earliest evidence of voyaging in New Zealand is a 600-year-old waka that was found buried in Golden Bay in 2012. While it was made from native New Zealand wood, it featured an intricate carving of a turtle on the hull, reminiscent not of Māori culture, but of Polynesia. In 1769, a Finnish explorer sketched a drawing of a waka off the coast of New Zealand. Yet, Matisoo-Smith says: “There’s no evidence that they were continuing to voyage those long distances. They didn’t need to anymore. They developed their own culture; they became people from Aotearoa [a Māori-language name for New Zealand].” Takoko says: “We don’t exactly know when the practice ended [long voyaging], but we know the waka hourua was a victim of that, and colonization ensured we didn’t practice it again.” The team restored a nearly 50-foot-long waka hourua, a double-hulled ocean-going canoe, which they named Hinemoana II after the Māori goddess of the ocean. Linda Bercusson The past 15 years have brought a resurgence in voyaging in New Zealand. This was largely done thanks to Micronesians who shared what they knew about the tradition and pioneers, such as the late Hekenukumai Busby. The Māori navigator and traditional waka builder helped promote education about the vessels. People started to crew the wakas that Busby built. Around the same time, voyaging societies launched in Fiji, Samoa and Tonga. The Cook Islands Voyaging Society was established earlier, in 1992. The voyaging societies started to build wakas using ancient techniques. Voyages are now taking place to retrace ancestral routes, strengthen connections between Pacific communities, highlight environmental issues and help teach the next generation traditional navigation skills. Restoring a canoe In August 2023, one of the sailors of the all-female crew heard there was a traditional waka more than 3,000 miles away in the Marshall Islands. The vessel was in a dilapidated state, but they really didn’t have another option. If they were to build a traditional double-hulled voyaging canoe from wood, it could take up to four years to complete and cost up to $1.6 million. “It was a leap of faith,” says Takoko. It took six months for the nearly 50-foot-long waka hourua, which they named Hinemoana II after the Māori goddess of the ocean, to be shipped to New Zealand. The team sought sponsorship for the cost of the waka from individual philanthropists and companies such as Rolex. The Tonga Voyaging Society and Te Whānau a Apanui iwi in New Zealand became the canoe’s guardians. The team finally started to restore the double-hulled canoe this February. An artisan restored the whakairo (carvings) in the steering paddle, while the crew helped patch the holes in the boat and restring the catamaran-like netting. It took six months before it was seaworthy. An artisan restored the whakairo (carvings) in the steering paddle. Tee Wells Whilst they were working on the waka, Conservation International connected them to Citizens of the Sea, a charity co-founded by the Cawthron Institute. Citizens of the Sea taught the crew members how to gather eDNA for research. The crew collected the eDNA with a torpedo-shaped device that is fitted with a 20-micron nylon filter, which collects plankton, biofilm and eDNA. Each day they would need to drag it behind the waka for five minutes at a time to sample the biodiversity of the ocean. “The eDNA will be going into the bigger pool of data for the region, seeing what species are present and absent,” says Schannel van Dijken, a marine biologist and Conservation International’s marine and heritage senior director. Whales not only digest and store large quantities of carbon-rich prey, but they also exhale very little carbon dioxide back into the atmosphere. This means they can act like a carbon sink and help protect against climate change. According to the U.S. National Oceanic and Atmospheric Administration, one whale can capture 33 tons of carbon dioxide over its lifetime. The women would need to set sail during the Southern Hemisphere’s winter if they wanted to arrive in Tonga in time for the whales’ arrival from Antarctica in July. The crew made sure they were as prepared as they could be. Those who weren’t already qualified sailors took their day skipper exams. They would help break up the monotony of studying with Tongan folk songs that helped them remember what they had learned. “It helped keep things fun, but song is the way we’ve always passed down information,” says Māori crew member Tee Wells. At the beginning of July, the crew managed to complete a four-day, 144-mile sea trial from Tauranga to Auckland. A swell hit, lifting the boat to 45 degrees and one of the experienced sailors, Wells, slipped on the deck and fractured her ribs, which meant she wouldn’t be able to join the main voyage. The waka handled the trial with ease. The only issue they had was a modern one, as the internet system they installed went down. The voyage begins As the waka departed from Auckland on the morning of July 22, Takoko offered a Māori prayer from the shoreline. “It was so beautiful. It was a leaving chant to safeguard us along the waters,” says co-captain Joelene Busby Cole from New Zealand. “I replied to her with, ‘One footstep, one heartbeat, one waka …’” Over the next ten days, the crew would follow the humpback highway from New Zealand, along the Kermadec Trench, through the Kermadec Islands to Tonga. The waters of these volcanic islands are one of the few places in the Pacific Ocean where whales, particularly humpbacks, gather. “There was huge element of uncertainty crossing the Kermadecs. It’s a big deal that they even undertook the voyage at the time of year that they did,” says Takoko. The crew worked tirelessly in shifts throughout the nights. But on some nights, the 16- to 22-foot swells crashing down on the deck meant that none of the crew got any sleep. More inexperienced members of the crew, who were yet to find their sea legs, battled seasickness in the first couple of days. Busby Cole, an accomplished sailor who was taught how to sail by her great uncle, Hekenukumai Busby, distracted the less experienced members of the crew with techniques on how to read the signs in clouds or stars, which could be used for navigation, while her co-captains steered. Some signs are spiritual, while others are practical. An albatross shows that you’re on the right track and your ancestors are along with you on the journey, Busby Cole explains. A ngoi bird would show the crew they were about 250 nautical miles off land. “At dusk, he’ll make a beeline straight for land,” she says. At every important landmark on the journey they would see a humpback whale breaching, a reminder of why they were making the trip. Alarmingly, it looked as if their journey might come to an end when their steering paddle broke toward the end of their voyage. However, the three co-captains were able to lash it together and make some rudimentary repairs at sea, which held it in place until they made it to shore. On August 1, the Hinemoana II finally arrived in Nukuʻalofa, Tonga, where a welcome party, including family, friends and people from Tonga Tourism, waited. The sailors were gifted garlands as they came ashore. For the crew from Tonga, it was a homecoming. For the other members of the group, it was a chance to create new bonds. The crew are now preparing the boat for the return journey in November, when they will capture eDNA as the whales migrate. When the waka arrives in New Zealand, it will be used as a floating classroom and research platform that will conduct citizen science, eDNA research, and species monitoring of whales and other marine mammals. And once licensed, visitors will be able to join them onboard. But this is just the tip of the iceberg when it comes to Pacific Islanders helping to protect the whales. Māori and Pacific leaders are calling for the whale to be given legal personhood. The data gathered from Hinemoana II will help paint a full picture of the threat to the whales. The proposal, which was put forward by the Hinemoana Halo and backed by the late Māori king Tūheitia Pōtatau Te Wherowhero VII, would give whales rights, including freedom of movement and a right to continue to enjoy their habitats free of pollution. The Māori have already shown how nature can receive personhood in law. In 2017, after a decades-long fight, the Māori gained legal personhood for New Zealand’s Whanganui River. Once the whale is identified as a person, a ship could then be penalized for maiming, hurting or killing that person. The Hinemoana II is the beginning of this vision. The aim is to use more wakas to help promote the restoration of whales as ecosystems. Takoko believes that if they can help save the whales, the whales could then help save the island communities. “As Indigenous people who are most vulnerable to climatic changes, no one is coming to save us,” says Takoko. “We have to come up with our own ways of being able to adapt to these huge changes that are going to [impact] our communities. Our survival is at stake.” Get the latest Travel & Culture stories in your inbox.

How Friends in South Carolina Are Restoring a Wetland and Bringing Their Neighborhood Together

Joel Caldwell and two friends have been working to improve wetlands in Charleston, South Carolina

CHARLESTON, S.C. (AP) — As the October night deepened and her bedtime approached, Joel Caldwell's 4-year-old daughter huddled with her dad, dangling a stick she pretended was a fishing pole over a creek that has become Caldwell's passion project for nearly the entirety of his daughter's life.“I want my children to grow up with a relationship to the natural world,” said Caldwell. “But we live in a neighborhood, so how do you do that?”The answer Caldwell and two of his friends came to was improving the creek that snakes into their section of Charleston — preserving its tidal flow, expanding its reach and rewilding its edges. This wetland is a transition zone where the land meets the bigger river. Their work here is small in scale and local, but it is tangible and has built a community at a time when it has gotten easier to destroy such places.With fewer wetlands there are fewer fish, fewer plants, fewer insects and birds, dirtier water and less protection against floods. That flooding is a special concern in hurricane-prone Charleston. Storm threats are compounded further by sea rise, which is being driven by climate change. The trio's restoration work fits into a growing public appreciation over the last 10 to 15 years for how wetlands help absorb floodwater.“We can be paralyzed by the bad news that we are fed every day, or we can work within our local communities and engage with people and actually do things,” Caldwell said. Amid isolation, restoration project was founded Caldwell has traveled the world as a freelance photographer. Then the COVID-19 virus hit right around the time his wife gave birth to their first daughter. From that stuck-in-place isolation, he and two friends, who were also having their first children at the time, founded The Marsh Appreciation and Restoration Society for Happiness Project, or The MARSH Project. Halsey Creek is mere blocks from Caldwell's house. The tidal salt marsh extends a few thousand feet from the Ashley River, one of three rivers that meet at Charleston, flowing between blocks of single-family homes many squeezed on one-tenth-of-an-acre lots.Neglected and abused in its urban setting, their first project was a community trash pickup on a hot day. They expected maybe a dozen people but ended up with 50, thanks to advertising by cofounder Blake Suárez, a graphic designer. Caldwell said people were clearly hungry to connect with their local environment.Over the years, they’ve pulled tires, radios, televisions, “generations of garbage” and even brought over winches to remove a car engine from the marsh. Wetlands viewed as an impediment to progress “It is going to be even harder to protect those wetlands that are left because the best tool we had to protect those wetlands, the federal Clean Water Act, is really being gutted,” said Mark Sabath, an attorney with the nonprofit Southern Environmental Law Center.The wetlands around Charleston support oyster beds that filter water and cling to long, wooden piers that stretch over shallow water and into the Ashley River. Kingfishers and egrets fly between the cordgrass. It's a humid, sticky place during blazing summers in the South. A vein of the river becomes Halsey Creek, shooting into the Wagner Terrace neighborhood, a suburban area north of Charleston's historic downtown. Waves of communities called it home after World War II: it was predominantly Jewish along with Greek and Italian immigrants in the decades following the war, shifting to African American in the 1960s and 1970s. Today, gentrification has created a mostly white community of more expensive homes.To help protect the wetlands, The MARSH Project's first significant conservation step was buying an acre of land from a local landowner.That acre is not obviously remarkable, running along a sloped strip that hugs the water, a runway of backyard grass on one side and bushes crowding the other. But the purchase ensures it will stay wetlands, not become new houses.“With the state of the world, and maybe my own sort of inclination, I’m not, like, naturally a happy person. So, this is like my form of therapy,” said co-founder Blake Scott, a historian who can recite the marsh’s role in Charleston dating back to when the British staged a nearby siege during the Revolutionary War.“The marsh makes me happy.” 'There is no gesture too small' Private homes abut the creek, so Scott has become its neighborhood salesperson. Out on a recent day, Scott spotted Jill Rowley, who lives near the end of the creek. He pointed to bare soil in the yard, explaining it would be an ideal spot for native plants to cleanse and slow rushing water, offering an expert’s gardening advice and possibly funding.“I never had an interest in the marsh or native (plants),” Rowley said. “And seeing this, and what is going on here, and really feeling like a steward and learning … I’ve just fallen in love with it.”Rowley can see what Scott is describing by looking across the street at one of their demonstration gardens. This is not a place for evenly spaced flowers surrounded by freshly cut grass. It’s a wilder mass of plants, with tall bending golden rod and Elliott’s aster that sprout purple flowers to attract pollinators deep in the fall. Native plants like these helped increase the bugs for the kids’ moth night that brought Caldwell's daughter, Land, to the creek that October night with her dad. The founders see events like this as one way of ensuring the next generation appreciates the importance of the ecosystem.Scott believes wetlands and wildlife could improve the neighborhood. For part of its length, the creek meanders and absorbs the tide, but a bisecting street constrains flow to its back half. Here it struggles to turn and expand. Nearby blocks flood easily into a suburban lake that can rise to a tall man’s waste. He wants to install better drains and a tidal gate to help the marsh absorb millions of additional gallons of that floodwater. The reaction from neighbors has been mostly, but not universally, positive, Scott said – a limited few resists public access near their property or picking up trash.The trio of founders are now starting to look outside of their neighborhood to create a corridor of native plants and trees to connect wildlife across the city’s few remaining creeks. It builds on four years of hosting public lectures, trash pickups, planting pollinator gardens, bringing in students for water quality testing and many other community events.Through them, they’ve found success focusing on an issue, and local actions — not broader politics.“It’s getting as many people as possible to change whatever their little piece of earth is,” Caldwell said. “There is no gesture too small.”The Associated Press receives support from the Walton Family Foundation for coverage of water and environmental policy.

Biofuel Pledge at Climate Summit Highlights India’s Ethanol Blending Debate

Earlier this year, the Indian government announced that it has achieved its target of mixing 20% of ethanol—considered a relatively cleaner fuel—with petrol or gasoline five years ahead of schedule

BENGALURU, India (AP) — India's push to blend ethanol with gasoline shows the benefits and challenges of the sustainable fuel efforts being showcased at global climate talks this week. Earlier this year, the Indian government announced that it achieved its goal of mixing 20% of the plant-based fuel with gasoline five years ahead of schedule. The world's most populous country is joining Brazil, Japan and Italy to promote ethanol and other biofuels as part of the Belem 4x initiative. The initiative, being showcased Friday at the COP30 climate summit, provides political support for expanding biofuels and relatively low-emission hydrogen-based fuels. Brazil, long a biofuel leader, commonly sells a 27% ethanol blend and its government recently announced plans to increase the percentage. India's rapid ethanol shift shows challenges other countries could face. While the Indian government said ethanol usage reduces pollution, some users said it is affecting their mileage and damaging older engines. Most fuel pumps in India now sell the 20% ethanol blend or unblended gasoline that’s nearly twice as expensive. Lower ethanol blends are being phased out. Environment experts also said grain production for ethanol can displace food crops and sometimes generates more planet-warming gases than it saves. Indian car owners say ethanol reduces mileage Ethanol, typically made from corn, sugarcane or rice, is considered cleaner than petroleum-based gasoline. The Indian government said its blending program has already cut carbon emissions by 74 billion kilograms (163 billion pounds)— equivalent to planting 300 million trees — and saved over $12 billion in oil imports in the last decade.“I think it’s good for the environment,” said Vijay Ramakrishnan, a businessman in Chennai. “But I’ve noticed a drop in mileage in my vehicle in recent months. Given how expensive fuel already is this further drop is only adding to my costs.”Ramakrishnan, who commutes over 100 kilometers (62 miles) daily, wants the government to offer more fuel choices.Amit Khare, who runs a popular YouTube channel on automobiles, said many followers complain about a significant drop in mileage from E20. Some owners of older cars have told him that they are having engine trouble.“E5 is the best fuel, E10 is manageable, but E20 has given a lot of trouble,” he said. Ramya Natarajan of the Bengaluru-based Center for Study of Science, Technology and Policy said ethanol can be good for some engines if they are compatible, but agreed that it can reduce mileage. Indian farmers want clarity on crops needed for ethanol Farmers said they need clarity on government procurement plans for ethanol production. Ramandeep Mann, a farmer in India's northern Punjab state, said farmers significantly increased corn acreage last year in hopes of selling it for fuel, but the price dropped after the government allocated large amounts of rice to ethanol makers. The amount of ethanol blended with gasoline in India grew from 8% to 20% in the last five years. Most of the ethanol now comes from grains, as opposed to the sugarcane, its traditional source. Mann said prices for sugarcane have also dropped this year. He said it’s good that the government is tackling climate change, but it should put farmers and their prices ahead of ethanol mandates. Previously, surplus crops not needed for food were the primary source of India's ethanol, but that's beginning to change, according to Natarajan of CSTEP. “With the push for E20 blends or even more, a lot more area has to be cultivated which in turn means it’ll be replacing other crops,” she said. Climate experts said biofuel production can have minimal environmental impact when it’s made from waste or inedible vegetation and processed in facilities that run on clean energy. But when crops are grown explicitly for biofuels, it has a higher carbon footprint because of the fertilizer and fuel involved.India’s ethanol strategy is part of a broader effort to reduce emissions, cut oil imports and boost agriculture, said Purva Jain, an energy specialist at the Institute for Energy Economics and Financial Analysis.But she said a faster transition to infrastructure for electric vehicles might be better. A 2022 study by her organization found that installing solar power for EV charging can be a much more efficient land use than growing crops for biofuel. However, ethanol producers have invested significant sums in manufacturing and need a steady, growing market for their product now, said CK Jain, president of the Grain Ethanol Manufacturers Association. He said India should increase the percentage of ethanol mixed with gas and encourage the sale of compatible vehicles. “We need to have higher blending as soon as possible, otherwise the industry will go into deep financial trouble,” Jain said. Other experts advocated for a middle ground. A 10% blend of ethanol with gasoline, can be a “win-win” solution said Natarajan of CSTEP. She said that would allow for use of existing crops without putting too much pressure on increased cultivation. Khare, the YouTube influencer, said keeping lower blends available would help older vehicles. “The government can bring E20 or even up to E85 programs on top of that, that’s completely fine. But consumers need to be given the option,” he said. The Associated Press’ climate and environmental coverage receives financial support from multiple private foundations.

If Trump’s EPA abandons climate policy, could California take over on greenhouse gases?

Legal experts, including a former federal official and UCLA professor, say California could go it alone if the federal government stops regulating greenhouse gases. One reason to try is to protect the state’s clean-car economy.

In summary Legal experts, including a former federal official and UCLA professor, say California could go it alone if the federal government stops regulating greenhouse gases. One reason to try is to protect the state’s clean-car economy. California has long cast itself as the nation’s climate conscience — and its policy lab. Now, as the Environmental Protection Agency moves to revoke the backbone of federal climate rules — the scientific finding that greenhouse gases threaten human health — one of the state’s top climate officials is weighing a provocative idea put forward by environmental law experts: If Washington retreats, California could lead on carbon-controlling regulation.   Absent what’s known as the endangerment finding, the EPA may soon consider abandoning the legal authority under the Clean Air Act to regulate greenhouse gases from vehicles, power plants and other sources, furthering the Trump Administration’s stated aim to dismantle U.S. climate policy.  While decrying the prospect of such a move, climate advocates say a repeal would yield a silver lining: California and other states could in theory set their own greenhouse gas rules for cars and trucks, regulations previously superseded by federal authority. Cars and trucks represent more than a third of California’s greenhouse gas emissions. A long shot regulatory gambit could clean some of the nation’s dirtiest air – and keep the state’s clean-car transition alive. “All options are currently on the table,” Lauren Sanchez, chair of the California Air Resources Board, told CalMatters in an interview. Authority states have never had before A former federal official and expert on the Clean Air Act – who is also a law professor at UCLA – first floated this idea.  Ann Carlson wrote in the law journal Environmental Forum that an aggressive federal action against climate policy “could, ironically, provide states with authority they’ve never had before.” The Trump administration now argues that greenhouse gases do not endanger health and that regulation is more harmful — a claim widely rejected by scientists, businesses and environmental groups, as well as states, including California.

Photo by Stella Kalinina for CalMatters “If greenhouse gases aren’t covered by the Clean Air Act,” Carlson told CalMatters, “then California could presumably regulate them — and so could every other state.” Carlson, who ran the National Highway Traffic Safety Administration until last year and has written extensively about the landmark law, argues that the act only preempts state rules for pollutants it actually covers. States “have a pretty strong legal argument” to regulate greenhouse gases, she said. The EPA, for its part, argues that states would still be barred from setting their own standards, arguing that its broad authority over air pollution covers even emissions the agency chooses not to regulate. That’s a view shared by the Alliance for Automotive Innovation, a trade association and lobbying group, which supported overturning California’s phaseout of new, gas-powered cars, as well as the American Trucking Associations, which has opposed some of California’s rules on trucks. Carlson said that argument doesn’t hold up. In her Environmental Forum article, she wrote: “If Congress didn’t intend the act to cover greenhouse gases, as the administration argues, then it’s hard to believe Congress intended to preempt states and localities from regulating them.” In other words, she says, preemption has its limits.  Other experts agreed the idea is worth considering.  Ethan Elkind, who directs the climate program at UC Berkeley’s Center for Law, Energy and the Environment, said that states are free to “do whatever they want,” as long as the federal government hasn’t preempted them.  Not a slam dunk for California to step in For the better part of a century, California has worked to curb air pollution at the state and local level. The state’s vanguard status positions it well to test Trump’s move to curb federal climate regulation, say experts.  “I personally would be advocating that they move ahead,” said Mary Nichols, a former air board chair. “And if I were there, I would be looking to gain support for doing it.” California holds a unique status under federal law. It can set tougher tailpipe-emission standards than the rest of the country — a recognition of its early leadership in fighting smog. Since 1968, the state has obtained more than 100 federal waivers for its vehicle rules, and other states can adopt California’s standards under certain conditions. UC Berkeley law professor Daniel Farber said the state could even take a dual-track approach. “We don’t really think we need a waiver,” he would argue after EPA abandons the field, “but just in case we do: yes, give us one.” California’s latest clash with Washington stems from a decades-long dance over who sets the nation’s toughest clean-car rules. The state’s strict vehicle rules have helped spur innovations from catalytic converters to cleaner fuel to electric cars. The regulatory push began in Los Angeles after skies grew so smog-choked they stung peoples’ eyes. In 1966, California adopted the nation’s first tailpipe standards. When Congress passed the 1970 Clean Air Act, it gave the state rare authority to set tougher rules — making California both a laboratory and a trailblazer, so long as it secured a federal waiver. In 2002, California passed the nation’s first law regulating greenhouse gas emissions from vehicles. The Supreme Court’s 2007 Massachusetts v. EPA ruling confirmed those gases are pollutants under federal law, leading to the Obama administration’s 2009 “endangerment finding” that they harm public health. Such a move would fit California’s pattern of pushing first and asking permission later. In 2005, the state adopted its greenhouse-gas standards for vehicles and sought a waiver before it was even clear whether carbon qualified as pollution under federal law. The EPA initially denied that request in 2008 but reversed course a year later, granting the waiver in 2009. “So this wouldn’t necessarily be a slam dunk approach for the state to take, but I think the legal avenue is now there,” said Elkin, of UC Berkeley. Targeting cars with new regulation If California tried to regulate greenhouse gases on its own, it would have both experience and infrastructure to rely on. The process would look a lot like how the state has written past clean-car rules — except this time, the target would be carbon itself. California’s clean-car rules have operated within the permission-seeking framework set up by the Clean Air Act — until this year, when Trump and Congress moved to block the state’s plans to phase out gas cars and tighten diesel-truck standards. Trump’s EPA then went further by proposing to repeal the 2009 endangerment finding, framing it as a win for “consumer choice.” Most of the state’s climate programs already run under authority of California’s own groundbreaking state laws: clean-energy mandates for utilities, a carbon-trading program for businesses, even standards to cut the carbon in fuels. Cars are different. They’re sold into a national market, and tailpipe emissions have long been federally preempted — one reason California has needed Washington’s permission to go its own way. If the state decides to test those limits, regulators would need to draft new rules and open them to public review — a process that could take years. California has already started down the path of new rules for clean cars and trucks. Last month, the Air Resources Board began the process of crafting clean car rules in response to the Trump administration’s rollback of the state’s new gas-car ban — a revocation the state is also fighting in court. In December, the board plans to begin the process of writing new emissions rules for trucks. The automobile association declined to comment on the new rulemaking effort.  Patrick Kelly, vice president of energy and environmental affairs for American Trucking Associations, said the group would work with its state affiliate to “respond to specific proposals. “ “More broadly, (our group) supports achievable national standards and opposes a patchwork of state and local standards that Congress sought to avoid,” Kelly wrote in an email. Gov. Gavin Newsom swears in incoming California Air Resources Board Chair Lauren Sanchez on Oct. 1, 2025. Photo courtesy of Office of the Governor Asked by CalMatters whether the new rulemakings could become the vehicle for California to go its own way under Trump, Sanchez, the air board chair, said it’s an option staff is studying. “It’s something that staff is looking into, and I look forward to digging into myself,” Sanchez said. No downside to trying, and some upsides Even if legal experts like the idea in theory, UC Berkeley’s Dan Farber says California going forward alone is a longshot in practice.  “There’s a chance you would win,” Farber said, of the argument that the state could directly regulate greenhouse gas emissions from cars. “You’re buying a lawsuit, but other than litigation expenses, I don’t think there’s much downside in trying to do it.” Farber and others point out that the Trump administration and car and truck manufacturers would almost certainly sue to block state-level efforts to regulate greenhouse gases.  The Alliance for Automotive Innovation warned, in comments to the EPA, that if states were not preempted, any unregulated emission “would then become fair game,” creating conflicting standards across the country. Automakers have long argued that letting states write their own climate rules would create a costly patchwork of standards, raising prices for consumers and complicating production for a national market. California is in somewhat of a legal quandary. The Clean Air Act requires California to meet national pollution standards, and the state still has some of the most air-polluted regions in the country. The state’s solutions rely heavily on clean-car and truck rules to meet those requirements. If California falls short, it could lose federal highway funding, a situation that Sanchez called a “no-win, Catch 22.”  After decades of regulation and incentives, California has built a reputation as a leader in electric cars, and experts said if the state pushes further on policy, that could help keep California’s clean-car transition alive and its electric-vehicle goals within reach.  Nick Nigro, founder of Atlas Public Policy, said California could also risk getting ahead of consumers if it goes it alone. Electric cars proved less popular than policymakers expected when it originally passed its goal to do away with sales of new gas-powered cars.  “What is clear is that the program was not overwhelmingly popular amongst the public, even in California, right?” Nigro said. “That’s usually a flag for policymakers.” Craig Segall, an independent consultant and former state air board deputy, said there’s another factor to consider: by preserving demand and infrastructure for EVs, the state could maintain a beachhead for innovation that a future president might build on. With no coherent federal policy to compete in the global EV market, California could again use its regulatory and investment muscle — just as it once did in helping spawn electric car maker Tesla — to push the market forward. “What the feds are basically signaling here is that the field is open for anyone who’s serious about being a competitive car or truck company in five years,” Segall said. “One of those paths is: the world’s fourth largest economy figures out ways to take its manufacturing economic capacity and just plow ahead.”

How thousands of fossil fuel lobbyists got access to UN climate talks – and then kept drilling

More than 5,000 fossil fuel lobbyists were given access to the UN climate summits over the past four years, a period marked by a rise in catastrophic extreme weather, inadequate climate action and record oil and gas expansion, new research reveals.Lobbyists representing the interests of the oil, gas and coal industries – which are mostly responsible for climate breakdown – have been allowed to participate in the annual climate negotiations where states are meant to come in good faith and commit to ambitious policies to reduce greenhouse gas emissions.The roughly 5,350 lobbyists mingling with world leaders and climate negotiators in recent years worked for at least 859 fossil fuel organizations including trade groups, foundations and 180 oil, gas and coal companies involved in every part of the supply chain from exploration and production to distribution and equipment, research shared exclusively with the Guardian has found.Just 90 of the fossil fuel corporations that sent lobbyists to climate talks between 2021 and 2024 accounted for more than half (57%) of all the oil and gas produced last year, according to the analysis by Kick Big Polluters Out (KBPO), a coalition of 450 organizations campaigning to stop the fossil fuel industry blocking and delaying global climate action.These corporations, which include many of the world’s most profitable private and publicly owned oil and gas majors, accounted for the production of 33,699m barrels of oil equivalent in 2024 – enough to cover more than the entire area of Spain with a 1cm blanket of oil.The same 90 firms also account for almost two-thirds (63%) of all short-term upstream fossil fuel expansion projects which are gearing up for exploration and production, according to the newly released Global Oil and Gas Exit List – a dataset which includes more than 1,700 companies covering more than 90% of global oil and gas activity.If executed, these expansion projects will produce enough oil – 2.623m km² at 1cm thickness – to coat the entire landmass of seven European countries (France, Spain, Germany, Denmark, Sweden, Finland and Norway) combined.The findings have renewed calls for fossil fuel companies and other big polluters to be banned from the annual climate negotiations amid mounting scientific evidence that the world has failed to limit the rise in global temperatures to 1.5C above preindustrial levels,.“This information clearly exposes corporate capture of the global climate process … the space that should be about science and the people has been transformed into a large carbon business hall,” said Adilson Vieira, spokesperson for the Amazonian Work Group. “While forest communities fight for survival, the same companies that cause climate collapse buy credentials and political influence to continue expanding their fossil empires.”“Not only are Indigenous peoples on the frontlines of their extractive sites suffering human rights violations, but we also face the brunt of climate chaos on our lands with worsening floods, wildfires, and extreme heat waves. We need to take down the ‘for sale’ sign on Mother Earth and bar entry to Cop for oil and gas lobbyists,” said Brenna Yellowthunder, lead coordinator for the Indigenous Environmental Network, a member of KBPO.The 30th UN climate summit (Cop30) opens on Monday in Belem, a city in the Brazilian Amazon – the world’s largest rainforest, which is being destroyed by ever-expanding fossil fuel exploitation, industrial agriculture, and mining, among other extractive industries.The annual meetings are where every country in the world negotiates on how best to tackle the climate crisis. The decisions should be driven by the legally binding United Nations Framework Convention on Climate Change (UNFCCC) treaty, and the 2015 Paris agreement to curtail global heating to under 1.5C.The research analyses the fossil fuel lobbyists known to have attended the negotiations in Glasgow (Cop26), Sharm el-Sheikh (Cop27), Dubai (Cop28) and Baku (Cop29). Until then, information about lobbyists was not collated by the UNFCCC.Growing anger at the lack of meaningful action by the world’s wealthiest, most polluting countries has been compounded by revelations that the fossil fuel industry appears to be granted greater access to the climate talks than most countries.Last year, 1,773 registered fossil fuel lobbyists attended the summit in Azerbaijan – 70% more than the total number of delegates from the 10 most climate-vulnerable nations combined (1,033).But the true reach of fossil fuel tentacles is undoubtedly deeper as the lobbyists data excludes executives and other company representatives on official country delegations participating directly in the confidential negotiations, and those attending as guests of governments, known as overflow delegates.The largest number of known lobbyists in recent years were representing state-owned companies from the United Arab Emirates, Russia and Azerbaijan.Many of the world’s most profitable fossil fuel corporations have also been present at recent Cop summits, at a time when governments faced huge public pressure – but failed – to agree to phase out fossil fuels despite deadly climate impacts affecting every corner of the planet.Between 2021 and 2024, Shell sent a combined total of 37 lobbyists, BP sent 36, ExxonMobil 32 and Chevron 20.In the past five years, the four oil majors made more than $420bn in combined profits.On Friday the Exxon CEO Darren Woods will headline a Cop30 launch event in Brasilia hosted by the US chamber of commerce called Pragmatic Business Solutions for Carbon Accounting and Emission Reductions. The US, which like every state is legally obliged under international law to tackle the climate crisis, has withdrawn from the Paris agreement and is not sending a country delegation to the summit.Petrobas, the majority state owned Brazilian multinational which sent at least 28 lobbyists to the past four climate summits, was recently grant ed a licence to conduct exploratory oil drilling in the sea off the Amazon, which is home to multiple Indigenous communities and about 10% of the planet’s known species.A spokesperson said: “Petrobras will be present at COP30, as it has been at previous talks, because it recognizes the opportunity to discuss sustainable models… The company’s participation in COP30 reinforces its commitment to follow and contribute to international debates on climate and energy.”Shell, BP, ExxonMobil and Chevron did not respond to requests for comment.After years of campaigning by civil society groups, Cop delegates this year are being asked to publicly disclose who is funding their participation – and confirm that their objectives are in alignment with the UNFCCC. But the new transparency requirement excludes anyone in official government delegations or overflows, and calls for stricter conflict of interest protections to cut industry influence have not been adequately heeded, advocates say.“The new rules are a welcome start, but they come decades too late … and transparency without exclusion is performative. You cannot claim to fix a process already captured by the very corporations burning the planet and fueling wars,” said Mohammed Usrof, executive director of the Palestinian Institute for Climate Strategy. “The UNFCCC must move from disclosure to disqualification… without reform this process will not save the world, and instead, will just help bury it.”UNFCCC has been contacted for comment.

Climate Risk Rarely Leads to ECB Collateral Downgrade, Blog Finds

FRANKFURT (Reuters) -The European Central Bank is already factoring climate-related risk into the assessment of collateral used to borrow money...

FRANKFURT (Reuters) -The European Central Bank is already factoring climate-related risk into the assessment of collateral used to borrow money from the bank but this rarely leads to credit rating changes, a blog post published by the ECB said on Friday.The ECB's 2021 climate action plan made the integration of climate risks into its collateral framework a key priority and the bank expects climate risk to be factored into credit ratings of assets posted by banks when they borrow from the central bank."While climate risks are widely recognised, they rarely lead to rating changes," the blog post, which does not necessarily represent the ECB's views, argued. "Several persistent challenges still limit the full and consistent integration of climate change risk into credit ratings."The ECB is using both its own in-house credit assessment systems and external rating agencies to determine climate risk but neither method has so far had a huge impact on collateral valuation.When using its in-house system, the share of credit ratings affected by climate risks is below 4% and the adjustments made are typically limited to one rating grade, the blog said.In the case of external agencies, environmental, social, and governance factors influence approximately 13% to 19% of all rating actions across the major agencies but climate change-specific downgrades account for only 2% to 7%, the blog post argued.While actual risk may be greater, assessment is difficult because banks can mask the vulnerabilities of some debtors, risk mitigation strategies can reduce their perceived exposure and because rating horizons are short- and medium-term, whereas climate risks tend to be long term, the blog said."Furthermore, reliable, granular climate change-related data remain scarce, particularly for smaller issuers, sovereigns and structured finance," it argued.(Reporting by Balazs KoranyiEditing by Tomasz Janowski)Copyright 2025 Thomson Reuters.Photos You Should See – Oct. 2025
