Democratic Senators Pressured EPA to Ease Rules on Steel Mill Pollution

Friday, April 5, 2024

This story was originally published by Grist and is reproduced here as part of the Climate Desk collaboration. In early March, a small group of Democratic senators from the Rust Belt sent President Joe Biden an urgent letter. They began by extolling the benefits of two of the Biden administration’s biggest achievements, the bipartisan infrastructure law and the Inflation Reduction Act, calling them “historic investments in our nation’s infrastructure” that will ring in a brighter future for American manufacturing. But there was something, they cautioned, that threatened to hamper this progress: the Environmental Protection Agency’s planned regulations for integrated iron and steel mills, proposed last July and nearing a court-ordered deadline. “We are concerned that the EPA’s proposed integrated steel rules will do what foreign competitors have thus far been unable to do: deter and diminish continued American investment in improving our steel industry,” wrote the five senators, among them Joe Manchin of West Virginia and John Fetterman of Pennsylvania. They claimed the regulations would cost companies billions, enough to force widespread layoffs, despite the EPA’s estimate of $7.1 million in costs for the two companies, US Steel and Cleveland-Cliffs, that own all 10 of the country’s steel mills. “The steel companies mounted a real disinformation campaign about the cost of the rule that I think put pressure on EPA.” Shortly after the senators sent off the letter, the EPA unveiled its final rule, the first time the agency has ever attempted to cut emissions from leaks and equipment malfunctions at steel mills. The EPA expects the new regulations will cut particle pollution by 473 tons every year. But the final rule is weaker than the one it proposed in 2023. Whereas the agency had originally planned to slash steel mills’ toxic emissions by 79 tons per year, a 15 percent decrease overall, the final version is expected to cut emissions by 64 tons each year. The EPA also dropped a proposed limit on the thickness of the smoke emanating from mills’ doors and roof vents.  Jim Pew, a senior attorney at Earthjustice who has litigated multiple lawsuits against the agency for its failure to curb steel mill pollution, told Grist that the regulations will have “real benefits” for the people living in the shadows of the country’s most polluting steel mills, but lamented the safeguards that were removed.  “It’s a small step in the right direction,” he said, noting that the EPA had furnished the final rule with a standard to regulate a type of incinerator used by some highly polluting mills. “The steel companies mounted a real disinformation campaign about the cost of the rule that I think put pressure on EPA to take out some provisions that would have been beneficial.” The new rule gives the country’s steel companies two years to update their facilities with the requisite emission reduction equipment and workplace standards. In an email, an EPA spokesperson said the agency had “carefully considered the stakeholder feedback and made data-driven modifications in the final rule that provide needed flexibility, while also providing health protections for surrounding communities.” The senators’ letter represents a rare occasion of congressional involvement in the EPA’s rulemaking process, a yearslong endeavor that requires extensive data collection and engineering expertise. The agency’s air pollution regulations, while undergirded by science and riddled with industrial jargon, have major consequences for communities that host the country’s industrial infrastructure, determining the quantities of toxic chemicals that companies can emit—and that residents can inhale.   The steel mills emitting black smoke in low-income communities are symbols of a prosperous past that politicians of both parties seem eager to protect.  Steel production is a highly polluting enterprise involving heating coal above 2,000 degrees Fahrenheit to produce a product known as coke, which is then combined with iron ore in a blast furnace and melted down into liquid steel. The broiling heat releases a slew of toxic heavy metals such as lead and arsenic, as well as fine particulate matter that can accumulate in the lungs after prolonged exposure. Numerous studies have linked pollution from steel mills to impaired heart and lung function. Ninety percent of the steel industry’s emissions originate from four mills that dot the rim of Lake Michigan near the border between Illinois and Indiana. Once bustling hubs for manufacturing, towns like Gary, Indiana, sank into decline over the latter half of the 20th century when manufacturing jobs were shipped overseas. Today, the steel mills that emit black smoke into the air of the area’s overwhelmingly low-income and Black communities are holdouts from this era, symbols of a prosperous past that politicians on both sides of the aisle seem eager to protect.  The first effort by members of Congress to convince the EPA to change its course came last December. A group of eight senators, including Democrat Amy Klobuchar of Minnesota as well as Republicans Mike Braun and Todd Young of Indiana, sent a letter to the EPA’s administrator, Michael Regan, arguing that the agency’s proposed regulations would harm national security by making the domestic steel industry—the “world’s cleanest major producer of steel”—uncompetitive. “We support reducing harmful air pollution,” they wrote. “We also support rules that are durable, realistic,” and based on the view that the federal government should “improve public health while protecting good-paying jobs and supporting industries essential to our national and economic security. These rules fail to meet those standards.” The senators did not specify which provisions in the proposed rule would have these effects. The letter in March from Manchin and the other Democrats brought even stronger warnings. “If these rules are promulgated as proposed, Cleveland-Cliffs and US Steel may be left with no choice but to prematurely shutter mills, resulting in job losses and irreparable harm to their local communities,” the senators argued. “They’re saying that not only did EPA understate the cost of these rules, but that it understated them by orders of magnitude.” In its final rule, the EPA estimated that the total costs to the steel industry would total $7.1 million, an amount that would cover the installation of air monitors to measure chromium pollution around the perimeter of facilities and the implementation of new workplace practices to reduce leaks from previously unregulated emission sources. But in a press release supporting the senators’ claim of costs running into the billions, Cleveland-Cliffs CEO Lourenco Goncalves argued that the rule would “put at risk good-paying, middle-class union jobs in the steel industry.” In 2023, U.S. Steel and Cleveland-Cliffs reported sales of $18 billion and $21 billion, respectively. Pew, the Earthjustice attorney, said concerns that the new rules will wreak havoc across the industry are unfounded. “The cost claims were so shocking to us, because EPA routinely overstates the cost of its rules,” Pew said, citing a study in 2020 from the National Association of Clean Air Agencies. “They’re saying that not only did EPA understate the cost of these rules, but that it understated them by orders of magnitude.” After taking note of the senators’ efforts to gut the steel mill regulations, Bruce Buckheit, the former director of the EPA’s air enforcement division, decided to send Regan a letter on behalf of Earthjustice in February. He dissected the contents of the new rule, arguing that its impacts would be “straightforward” and meet the minimum pollution reductions required by the federal Clean Air Act. “I’ve seen nothing in the rulemaking record for these proposals that supports the cost claims in the senators’ letter,” he wrote. The total capital expenditures, he concluded, would be minuscule compared with U.S. Steel’s and Cleveland-Cliffs’ revenues. “I believe it is important to push back against such overblown industry claims, lest that narrative drive public opinion and agency policy,” Buckheit wrote.

4 hottest days ever observed raise fears of a planet nearing ‘tipping points’

Read more

As global temperatures spiked to their highest levels in recorded history on Monday, ambulances were screaming through the streets of Tokyo, carrying scores of people who’d collapsed amid an unrelenting heat wave. A monster typhoon was emerging from the scorching waters of the Pacific Ocean, which were several degrees warmer than normal. Thousands of vacationers fled the idyllic mountain town of Jasper, Canada ahead of a fast-moving wall of wildfire flames.By the end of the week — which saw the four hottest days ever observed by scientists — dozens had been killed in the raging floodwaters and massive mudslides triggered by Typhoon Gaemi. Half of Jasper was reduced to ash. And some 3.6 billion people around the planet had endured temperatures that would have been exceedingly rare in a world without burning fossil fuels and other human activities, according to an analysis by scientists at the group Climate Central.These extraordinary global temperatures marked the culmination of an unprecedented global hot streak that has stunned even researchers who spent their whole careers studying climate change.Since last July, Earth’s average temperature has consistently exceeded 1.5 degrees Celsius (2.7 degrees Fahrenheit) above pre-industrial levels — a short-term breach of a threshold that scientists say cannot be crossed if the world hopes to avoid the worst consequences of planetary warming.This “taste” of a 1.5 degree world showed how the natural systems that humans depend on could buckle amid soaring temperatures, said Johan Rockström, director of the Potsdam Institute for Climate Impact Research in Germany. Forests showed less ability to pull carbon out of the atmosphere. Sea ice around Antarctica dwindled to near record lows. Coral bleaching became so extreme scientists had to change their scale for measuring it.Even as scientists forecast an end to the current record-breaking stretch, they warn it may prove difficult for parts of the planet to recover from the heat of the past year.“The extreme events that we are now experiencing are indications of the weakening resilience of these systems,” Rockström said. “We cannot risk pushing this any further."This week’s broken records come on the heels of 13 straight months of unprecedented temperatures — fueled in part by the planet’s shift into an El Niño climate pattern, which tends to warm the oceans, as well as pollution from burning coal, oil and gas.The warming neared its apex on Sunday, when data from the Copernicus Climate Change Service, the European climate monitor, showed the global average temperature edging out a record set a little over a year earlier.But the new benchmark only stood for 24 hours, with Monday hitting a historic 17.16 degrees Celsius (62.89 degrees Fahrenheit). Tuesday was the second hottest on record, and Wednesday tied Sunday as the third warmest.Though these numbers may not seem extreme, they are the average of thousands of data points taken from the Arctic to the South Pole, in places that are experiencing winter as well as those in the midst of summer. The preliminary data was generated using a sophisticated type of analysis that combines global weather observations with a state of the art climate model — a method that outside researchers said Copernicus’s is highly reliable.The world’s oceans are also awash in historic heat. Copernicus data shows that the waters around Taiwan are 2 to 3 degrees Celsius (3.6 to 5.4 degrees Fahrenheit) hotter than normal, helping to fuel Typhoon Gaemi’s devastation. Research shows that higher ocean temperatures give more power to tropical cyclones, while a warmer atmosphere can hold more water — and thus produce more rain.Meanwhile, nearly 2,000 weather stations around the planet notched new daily high temperature records over the last seven days, according to the National Centers for Environmental Information.Although scientists have not yet quantified the role of warming in all of this year’s extreme events, there is abundant evidence that heat waves, storms and fires are made more frequent and intense because of climate change.“We are running out of metaphors” to describe the unrelenting pace and scale at which the world is now breaking records, Copernicus director Carlo Buontempo said.Sometimes, he said, he feels like the planet’s temperature is a helium balloon drifting inevitably upward. All he can do is stand below and say “look, it is higher.”Scientists have estimated Earth’s average temperature based on observations dating back to 1850, and now measure it by pulling data from more than 20,000 land-based stations as well as readings from ships and buoys around the globe,To convey the severity of Earth’s current heat, other researchers have turned to the planet’s past. By studying tree rings, lake sediments and other records of the ancient climate, paleoclimate researchers have determined that the world is likely now warmer than it has been in more than 100,000 years, since before the start of the last ice age.Humanity now faces conditions unlike anything our species has known before. According to a Climate Central analysis of the five-day period ending Friday, nearly half of the planet experienced at least one day of “exceptional heat” — temperatures that would have been rare or even impossible in a world without climate change.United Nations Secretary General António Guterres on Thursday called for improved warning systems, stronger worker protections and other policies to protect people from these scorching temperatures.“Extreme temperatures are no longer a one day, one week or one month phenomenon,” he said at a press conference.Buontempo expects that Earth’s record-breaking streak may soon end. The National Oceanic and Atmospheric Administration last month declared an official end to the El Niño, reflecting cooling conditions in the tropical Pacific Ocean. The end of summer in the Northern Hemisphere — where most of the world’s land is — also tends to bring down the planet’s overall temperature.Yet the unprecedented amount of heat-trapping carbon in Earth’s atmosphere — which is at its highest level in more than 3 million years — will mean that even without El Niño, the world remains perilously warm. Many researchers project that 2024 will end as the hottest year on record, exceeding the benchmark set in 2023.“The fluctuations we’re seeing are relatively modest on top of a very large, decades-long warming trend,” said climate scientist Kim Cobb, director of the Institute at Brown University for Environment and Society. “We’re dancing about a climate average that is very dangerous for communities and ecosystems around the world.”The worst of this week’s heat was concentrated in Antarctica, where temperatures were as much as 12 degrees Celsius (21.6 degrees Fahrenheit) above normal.Lynne Talley, a researcher at the Scripps Institution of Oceanography at the University of California at San Diego, said that anomaly is likely the product of strong winds pushing warm air onto the continent. Those conditions will make it more difficult for the ocean to freeze during what is usually the prime time for sea ice formation.“It seems like global warming is finally catching up with Antarctica, and that’s pretty frightening,” she said.The amount of sea ice around Antarctica is already at its second lowest level on record for this time of year — coming in just behind last July. After losing an unprecedented amount of ice cover during the 2023 melt season, Talley said, the region has been unable to rebound.To Rockström, the decline in Antarctic sea ice is one indication of how the recent global heat may be undermining the planet’s ability to buffer against some of climate change’s worst impacts. Sea ice helps keep the poles cool by reflecting much of the sunlight that hits it back into space. When the ice melts, and the sun’s rays can reach the dark open ocean, their energy is absorbed by the planet.He also pointed to a new analysis that found the wilting and burning forests of the Amazon, Asia and Canada had lost much of their ability to absorb the excess carbon dioxide produced by human activities. The research, which has not yet been published in a peer-reviewed journal, focused on data from 2023 — meaning scientists are still unsure whether the finding represents a short-term blip or a more permanent shift.This year, the world’s forests are struggling once again. As of Wednesday, Canadian authorities were battling 310 uncontrolled wildfires, including the blaze that ravaged the town of Jasper. Trees turned to tinder by weeks of extreme heat are fueling a fast-moving fire in Northern California. The Amazon is bracing for a second consecutive year of an extreme drought that studies show is fueled by climate change.Robert Rohde, chief scientist for the climate data nonprofit Berkeley Earth, called these extreme events “suggestive” of what will happen to the planet if global temperatures consistently exceeds 1.5 degrees Celsius of warming — something that researchers project will occur in the early 2030s.Studies indicate that crossing that threshold could trigger irreversible changes in major Earth systems: the collapse of the Greenland ice sheet, complete loss of tropical coral reefs, abrupt thawing of some permafrost.What the world is seeing now, Rockström said, is a “worrying sign of potentially approaching tipping points.”And as long as people continue adding carbon to the atmosphere, Cobb said, disasters will continue to happen and records will continue to fall.“It’s a Russian roulette wheel of climate devastation,” she said. “Whether it’s going to be your community in the line of a hurricane, or your city is going to have a heat wave. The threat is here and it’s now.”

The Olympics Need to Change as the Climate Changes

Organizers must reduce the event’s carbon footprint.

The organizers of the Paris Olympic Games have outdone their predecessors in trying to make the Games the most sustainable in the decades since climate change became a concern. But with an estimated 11 million tourists converging on the City of Light for the Olympics, including 1.5 million from abroad, the Games can only be so green.On the plus side, organizers have been serious in their efforts to reduce carbon emissions. They measured the expected carbon footprint of the Games, reduced emissions through energy efficiencies, limited new construction by using existing facilities, added bike lanes, minimized the use of fuel-powered generators and sourced sustainably produced goods for medals and podiums and much of the event materials.Perhaps most important, they’ve talked about their sustainability work at every turn, drawing attention to unsexy details and raising public awareness of environmental issues such as air pollution and extreme heat in France and beyond.Still, international travel is a big contributor to the overall carbon impact of the Games. Organizers of the Rio Olympics in 2016 predicted that slightly more than half of the carbon emissions would come from spectators. Of that amount, 80 percent was expected to be generated by international fans traveling to and from the Games. Organizers saw a low potential to reduce those emissions and said they would need to compensate elsewhere in the preparation and running of the events.What else is to be done? If the world is serious about reducing carbon emissions, the Olympics, like so much else, will have to change even more. Jules Boykoff, who has written extensively about the Olympic Games, rightly argues in Scientific American that “the Games need to reduce their size, limit the number of tourists who travel from afar, thoroughly greenify their capacious supply chains and open up their eco-books for bona fide accountability.”The sustainability efforts in Paris have not all been smooth sailing. The Seine is scheduled to host marathon swimming and the swim portion of the triathlon. But despite spending 1.4 billion euros trying to clean the river, French authorities have achieved inconsistent results: Water tests in June still showed high levels of E. coli. Those numbers improved and crept into the range of safe to swim in late June and early this month. Anne Hidalgo, the mayor of Paris, recently took a swim in the river after canceling an earlier planned plunge because of those high bacteria levels. Her swim was promising, but one heavy rainfall could draw more pollutants into the river and undo much of the progress she celebrated.Subscribe to The Times to read as many articles as you like.

Canada’s 2023 Wildfire Season: An Unprecedented Environmental Catastrophe

The 2023 wildfire season in Canada, the most destructive on record, released significant amounts of arsenic, particularly from mining-impacted areas around Yellowknife, posing increased environmental and health risks.A study has found that contaminated mining sites increase the risks associated with fires.The 2023 wildfire season in Canada was the most destructive ever recorded, and a new study suggests the impact was unprecedented. The research found that four wildfires in mine-impacted areas around Yellowknife, Northwest Territories, potentially contributed up to half of the global annual arsenic emissions from wildfires.The work, led by researchers at the University of Waterloo and Nipissing University, is the first to calculate the amount of arsenic that was stored in areas at high risk of wildfires around Yellowknife. Looking at data from the past five decades, the team estimates the 2023 wildfires potentially released between 69 and 183 tonnes of arsenic.Arsenic, a potent toxin, that the World Health Organization associates with diabetes, cardiovascular disease, various cancers, and infant mortality, can be transformed by wildfire and released into the environment from the soils that normally sequester it. The Growing Risk of WildfiresGiven that the frequency and severity of wildfires are expected to increase because of climate change, the researchers caution that in any regions in the world where annual wildfires intersect with past or present mining and smelting operations, future fires could present a major risk for releasing stored toxins back into the environment.“Yellowknife has a decades-long history of mining, which has led to an accumulation of arsenic in the surrounding landscape. However, Yellowknife is not unique in this regard, Canada has many industrially contaminated sites that are vulnerable to wildfire,” said Dr. Owen Sutton, a postdoctoral fellow in the Faculty of Environment at Waterloo.The amount of arsenic released by wildfires depends on a multitude of factors, such as fire temperature, depth of the burn, and soil type, and the combination of these variables.“While our research has raised the alarm on this issue, we will be the first to argue there is an urgent need for collaborative investigation by wildfire scientists, chemists, environmental scientists, and policy experts,” said Dr. Colin McCarter, professor in the Department of Geography at Nipissing University and Canada Research Chair in Climate and Environmental Change. “By integrating diverse fire management techniques, including Indigenous fire stewardship, we can hopefully mitigate these emerging risks to human and environmental health.”The researchers found that arsenic emissions from wetlands were the most concerning because of their tendency to store contaminants compared to forests. Moving forward, they will continue quantifying the amount of toxins being stored by northern peatlands and study the potential release of other metals from those landscapes.Reference: “Globally-significant arsenic release by wildfires in a mining-impacted boreal landscape” by O F Sutton, C P R McCarter and J M Waddington, 20 May 2024, Environmental Research Letters.DOI: 10.1088/1748-9326/ad461a

As a Toxic Haze Blurs the Rockies, Residents Worry About Plans for More Drilling

During Colorado’s ‘ozone season,’ children and adults alike stay indoors. Drilling wells near the suburbs could make it worse. The post As a Toxic Haze Blurs the Rockies, Residents Worry About Plans for More Drilling appeared first on .

For more than half the days since May 31, a toxic haze has blurred the towering Rocky Mountains along the eastern Front Range, prompting Colorado health officials to warn residents to reduce time outdoors to avoid damage to their lungs.   The smog forced older adults to forgo walks, asthma sufferers to reach for inhalers and parents to keep toddlers inside. It also heightened concerns about what it might mean for 3 million people here if state regulators approve oil and gas proposals that call for scores of new wells. Emissions from energy industry operations and traffic are the main drivers of the nine-county metropolitan Denver region’s failure to meet federal air quality standards for the last two decades.   “I am completely dumbfounded!” Aldo Plascencia, an Aurora resident who lives near where hundreds of new wells would be drilled, wrote on a community Facebook page on July 11.   “When dropping my kids at school this morning, parents were being notified that all outdoor field trips were being canceled today due to high ozone activity,” he added. “Why would anyone in their right mind consider permitting fracking so close to schools and houses — this will make matters worse.”   A decision on a 156-well Lowry Ranch proposal is imminent — state regulators have scheduled a hearing for July 30. Drilling would occur along the southeastern edge of greater Denver, under homes, a reservoir that holds the region’s drinking water and adjacent to one of the nation’s most polluted Superfund sites.    The 50-square-mile site is also near air monitors that recorded some of the region’s worst air pollution levels from 2019 to 2022. In the first 10 years of operation alone, the Lowry Ranch project would emit hundreds of tons of smog-forming compounds per year, as well as tens of thousands of tons of climate warming gases, according to Geosyntec, a consultant hired by Crestone Peak Resources, the operator proposing the plan. The wells could be in operation for 25 years.     In the month after this year’s annual “ozone season” began May 31, Colorado health officials issued more air quality alerts than in any similar period since 2016.     Cities along the eastern flank of the Rockies already rank among the worst in the nation for lung-damaging ozone pollution, according to the American Lung Association’s 2023 “State of the Air” report. Denver was ranked sixth worst, with  every county in the area receiving a failing grade. Pollution is so bad some days that a monitor at Rocky Mountain National Park registers levels that violate Environmental Protection Agency standards.   Greater Denver’s topography, which traps pollutants, contributes to the intractable problem, as does human-caused climate change. Global warming made June’s record hot conditions — the second warmest since 1872 — “more likely,” according to Climate Central, an organization that uses data and science to link weather-related events to global warming.   Colorado’s most densely populated area overlaps with some of the nation’s most profitable oil and gas fields — amplifying the health risk. The state tied with Alaska as the country’s fourth-largest oil producer and ranked as its eighth-biggest gas producer.   Vehicles and oil and gas operations emit nitrogen oxides and volatile organic compounds, which react when heated by the region’s plentiful sunlight to create ground-level ozone. In the month after this year’s annual “ozone season” began May 31, health officials issued more air quality alerts than in any similar period since 2016.   “We are having a difficult year,” Mike Silverstein, executive director of the Regional Air Quality Council, said at an online planning forum on July 18. The council advises state regulators on strategies to curb pollutants.   “We are exceeding the ozone standards at most of our monitoring stations,” he added, and “we are midway through ozone season.”   According to estimates used by the council, by 2026, emissions from oil and gas operations will comprise about 36% of the 253 tons per day of volatile organic compounds released in the region’s atmosphere. The second highest emitting category will be vehicles at 11%.   The industry is expected to account for 47% of the 144.5 tons of nitrogen oxide emitted per day in 2026 — more than three-and-a-half times as much as power plants and other large permitted facilities that pollute combined, according to the models used. It’s not possible, however, to draw a straight line from these percentages to the proportion of the region’s ozone pollution created by oil and gas extraction, David Sabados, the air quality council’s communications director, said in an email.   Because of where oil and gas “operations are located, as well as specifics of the types of volatile organic compounds that come out of drilling,” he wrote, “it’s estimated that cars are nearly as responsible for ozone creation as oil and gas.”     A total of 56 oil and gas wells are planned within one mile of the Aurora Reservoir, a major source of drinking water.     Regardless of what causes them, the emissions can be deadly. Air pollution from fossil fuel production in the U.S. in 2016 resulted in 7,500 excess deaths, 410,000 asthma incidents and 2,200 new cases of childhood asthma, with $77 billion in total health impacts, scientists found in a 2023 study published in Environmental Research: Health.   States with high oil and gas related emissions but lower population, such as Colorado and New Mexico, “have the highest impacts per million people,” scientists found.   “If you take any region that has a lot of people and put an air pollution source in it, all evidence points toward you would expect health impacts,” Jonathan Buonocore, the study’s lead author and an assistant environmental health professor at Boston University, told Capital & Main.   Crestone Peak Resources, the company proposing the 156-well project near suburban Aurora, said in documents filed with the Energy & Carbon Management Commission that it planned to mitigate emissions by electrifying drill rigs, among other strategies, so its operations would create “no adverse health risks to nearby communities, including sensitive individuals.”   To date, areas to the south and east of the Denver metropolitan area have seen little oil and gas development, compared to the state’s largest fossil fuel field north of the city. That could be about to dramatically change. A Capital & Main/FracTracker Alliance investigation found that the Lowry Ranch project, and a nearby 20-well plan proposed by GMT Exploration Company, LLC, could, if approved, result in about 229 wells being drilled near Aurora, the state’s third largest city.   A total of 56 wells are planned within one mile of the Aurora Reservoir, a major source of drinking water, the investigation found. About 125,000 people live within five miles of the proposed projects, the analysis showed.   These projects represent an expansion of fossil fuel production from Weld and Broomfield counties, to the north, looping around Denver’s eastern edge, where drilling will take place just yards from dense suburbs, an interactive map created using existing well locations, pending and approved permits and drilling proposals kept by the Energy & Carbon Management Commission found.

To celebrate the 200th anniversary of the annexation of Nicoya County, Coopenae, the Environmental Bank Foundation (FUNBAM), and the Volunteer Fire Brigade (AAAS Tamarindo) have joined forces to initiate the Bicentennial Forests Project. In the first stage, 1,000 endemic trees will be planted in San Francisco Park, part of the Baula Marine Reserve, at the Liceo de la Comunidad 27 de Abril high school, and in the El Trapiche sector. This initiative aims to reforest these areas and mitigate the risks associated with climate change. The project will enhance the water recharge areas of Guanacaste, which have been affected by forest fires, and provide training and education to young people in socially vulnerable situations. This will promote the development of soft skills, equipping them with tools to improve their quality of life. This year, there have been 141 forest fires, 90 of which have occurred in Guanacaste, affecting a total of 28,000 hectares. Coopenae’s Bicentennial Forests will also create green jobs for female heads of households in the area. They will be responsible for the care and maintenance of the trees, primarily Jícaros, for five years until the trees reach the recommended height and adapt to the environment. The forest will be enriched with native species, and the planting will be alternated with tree varieties that have forest viability and several species that directly benefit the aquifers. “We have generated the Bicentennial Forests here in the areas of Tamarindo, El Trapiche, and 27 de Abril. These projects enrich the secondary forest, and we are planting native trees such as Jícaro, laurel, Guanacaste, guacalillo, and beach almond to bring freshness to the locality. This initiative has an environmental background and a social focus,” said Victor Sequeira, coordinator of FUNBAM’s Footprint of the Future Program. In addition to the immediate benefits of reforestation and job creation, the Coopenae Bicentennial Forest is designed with a long-term focus. The inclusion of native species and forest viability ensures not only the recovery of local biodiversity but also the sustainability of the ecosystem over time. This holistic approach seeks to restore the natural balance and strengthen the region’s water resources.
