My town became environmentally conscious and so did I

With the environment constantly changing due to global warming, future generations will have a chance only if the current population takes sustainable actions.

Growing up, I realized that children are a product of their environment, so let me tell you a little bit about mine: I grew up in Secaucus, N.J., a town called “the Jewel of the Meadowlands.” My suburban hometown exists within a large ecosystem of wetlands, the Meadowlands, through which the Hackensack River flows. But with post-agricultural pig farm effluent and debris from New York’s train station decay being dumped into the area, the Meadowlands became a jewel in need of polishing.Secaucus is working to recover the natural marshes by designating them as protected so fewer apartment complexes can be built and begin to sink a few years down the road, which has happened in the past. The town became environmentally conscious, and existing within that environment, I did the same.In high school, I worked with the Secaucus Environmental Department for over three years as part of the Next Generation Community Leaders, or NGCL, program created by the Lindsey Meyer Teen Institute. Little did I know just how much this experience would influence my life. Throughout that time, I learned about climate change, the planet’s environmental challenges, and the actions we need to take to reduce our footprint. I helped implement a plastic bag and Styrofoam ban, designed a food waste composting system at my high school and local gardens and created eco-friendly living PSAs. I canvassed to promote eco-friendly living and educated residents on how to compost at home.I also certified local businesses as “green,” depending on whether they followed practices set by the Sustainable Jersey network. These practices included recycling, reducing food waste, not using Styrofoam, etc. My contributions to the environmental department helped Secaucus to earn recognition from Sustainable Jersey as a Silver Certified Community.That experience showed me how local actions can create change. By educating residents in Secaucus, we altered their behaviors, if even slightly, to be more environmentally conscious. Residents began to grow produce in the community gardens, compost at home and reduce their plastic bag usage. I witnessed how humans responsible for harming the planet have the potential to make changes to fix it and make it better for future generations. From that day forward, I carried that responsibility with me.I will be honest: I don’t know the current status of those projects I worked on in Secaucus. I hope that residents are still composting at home and that those businesses continue their green practices.I began my journey into learning about sustainability at USC with a major in industrial and systems engineering and a minor in law and public policy. Although these are not fields directly tied to the climate ecosphere, my advocacy in Secaucus made me realize that a systematic mindset and policy knowledge would be strong tools with which I can effect change within both the government and private sector in advocating for larger-scale sustainability solutions. With the opportunities provided by USC, I knew I could get involved in environmentalism and sustainability without having to be an environmental science major. “We have canvassed [local] youth ... and discovered that their top environmental priorities are cleaner air, green spaces and green buildings,” says Alyssa Jaipersaud, a member of the L.A. County Youth Climate Commission. (Michael Blackshire / Los Angeles Times) If you asked freshman Alyssa what her ultimate career goal was, she would have said, “Facilitate systemic change within the bureaucracy through ecological and climate-preservation policies to make society more sustainably conscious.” I wrote this on an index card and kept it in my backpack throughout college to constantly remind me of the goal because being an environmentalist can be discouraging, given the current climate.Since then, I think I would have made freshman Alyssa proud. I was accepted into the USC Student Sustainability Committee and became a mentor to new members. The SSC acts as a representative for the student body within the Presidential Working Group for Sustainability. We work on projects such as getting reusable takeout containers in dining halls, ensuring ongoing campus construction is adhering to green practices, and creating a central physical space where sustainability-minded students can gather. As a member of the SSC, I ensured that sustainability would become a standard educational practice at USC and change student behaviors toward respecting their environment. I continued my education at USC by pursuing a master’s in sustainable engineering, and I have earned the distinction of a National Academy of Engineering Grand Challenges Scholar by focusing on sustainability. Alyssa Jaipersaud poses for a portrait at Exposition Park Rose Garden. (Michael Blackshire / Los Angeles Times) My environmental pursuits have culminated in my becoming a Los Angeles County Youth Climate commissioner in the world’s first such organization. We have canvassed the youth in L.A. County and discovered that their top environmental priorities are cleaner air, green spaces and green buildings. Now, as a member of the legislative committee, I track all federal and state measures that relate to these priorities and bring them to the attention of the county Board of Supervisors so that they can weigh in on whether the legislation should be amended, supported or rejected. We are working actively to support legislation currently going through the U.S. Senate that would call for establishing opportunities for youths to be involved in policy development so they can ensure a healthy environment for their future and those to come.Since children are a product of their environment, we should help future generations have a good environment to live in. With the environment constantly changing due to global warming, future generations will have a chance only if we work to make the world sustainable starting today. Instead of forcing future generations to learn how to survive to fix the environmental mistakes we are making today, they should have the opportunity to live without the repercussions of the past. I witnessed the negative effects of a mistreated environment in my hometown, and I want to make sure future generations aren’t suffering from the consequences of what we are doing. With a sustainability mindset, local changes can influence the politicians and create the systemic change needed to get the biggest offenders under control. One of the significant steps is behavioral changes, which can begin locally and be brought by people not even studying in the environmental field, just like me.Alyssa Jaipersaud earned a bachelor of science in industrial and systems engineering with a minor in law and public policy at USC and is also completing a master’s of science in sustainable engineering. She is setting her sights on a full-time role in the sustainability industry either as a consultant or practicing engineer.

AI Has Helped Shein Become Fast Fashion’s Biggest Polluter

The company nearly doubled its emissions in 2023, making it the worst actor in a notoriously unsustainable industry.

This story originally appeared in Grist and is part of the Climate Desk collaboration.In 2023, the fast-fashion giant Shein was everywhere. Crisscrossing the globe, airplanes ferried small packages of its ultra-cheap clothing from thousands of suppliers to tens of millions of customer mailboxes in 150 countries. Influencers’ “#sheinhaul” videos advertised the company’s trendy styles on social media, garnering billions of views.At every step, data was created, collected, and analyzed. To manage all this information, the fast fashion industry has begun embracing emerging AI technologies. Shein uses proprietary machine-learning applications — essentially, pattern-identification algorithms — to measure customer preferences in real time and predict demand, which it then services with an ultra-fast supply chain.As AI makes the business of churning out affordable, on-trend clothing faster than ever, Shein is among the brands under increasing pressure to become more sustainable, too. The company has pledged to reduce its carbon dioxide emissions by 25 percent by 2030 and achieve net-zero emissions no later than 2050.But climate advocates and researchers say the company’s lightning-fast manufacturing practices and online-only business model are inherently emissions-heavy — and that the use of AI software to catalyze these operations could be cranking up its emissions. Those concerns were amplified by Shein’s third annual sustainability report, released late last month, which showed the company nearly doubled its carbon dioxide emissions between 2022 and 2023.“AI enables fast fashion to become the ultra-fast fashion industry, Shein and Temu being the fore-leaders of this,” said Sage Lenier, the executive director of Sustainable and Just Future, a climate nonprofit. “They quite literally could not exist without AI.” (Temu is a rapidly rising ecommerce titan, with a marketplace of goods that rival Shein’s in variety, price, and sales.)In the 12 years since Shein was founded, it has become known for its uniquely prolific manufacturing, which reportedly generated over $30 billion of revenue for the company in 2023. Although estimates vary, a new Shein design may take as little as 10 days to become a garment, and up to 10,000 items are added to the site each day. The company reportedly offers as many as 600,000 items for sale at any given time with an average price tag of roughly $10. (Shein declined to confirm or deny these reported numbers.) One market analysis found that 44 percent of Gen Zers in the United States buy at least one item from Shein every month.That scale translates into massive environmental impacts. According to the company’s sustainability report, Shein emitted 16.7 million total metric tons of carbon dioxide in 2023 — more than what four coal power plants spew out in a year. The company has also come under fire for textile waste, high levels of microplastic pollution, and exploitative labor practices. According to the report, polyester — a synthetic textile known for shedding microplastics into the environment — makes up 76 percent of its total fabrics, and only 6 percent of that polyester is recycled.

Why Melbourne’s e-scooter ban is a wrong turn away from safe, sustainable transport

Shared e-scooters have safety features that private e-scooters lack, but accident data don’t distinguish between them, nor tell us about the economic and environmental harms of other transport modes.

Melbourne City Council voted to break its contracts with operators of shared e‑scooter schemes this week, citing safety concerns. It seems these concerns have usurped the long-term transport and environmental gains from moving towards sustainable transport. A year ago, the city reported emissions had been cut by 400 tonnes since trials of these e‑scooters began. Shared e‑scooters only became available to Melburnians in early 2022. But electric scooters have existed for more than a century. They were very popular on public streets in the United States after motorised scooters first appeared in 1915. However, their use for criminal getaways soon marred their reputation. The opportunity for a lower-emission, more equitable form of transport was lost, until now. It could be lost again because of knee-jerk reactions to concerns about their safety. In fact, shared e‑scooters have safety features that individually owned ones often lack. Shared e‑escooters cause fewer serious injuries than bicycles or motorcycles, according to New Zealand accident compensation data. In Australia, while there has been a rise in numbers treated in hospitals for e‑scooter injuries, no distinction is made between shared and private e‑scooters. Private e-scooters greatly outnumber shared ones Today, an estimated 15,000 shared e‑scooters are in use across Australia and New Zealand. No official figures are available for private e‑scooters, but there are likely to be many more of them. Segway, a globally dominant maker of e‑scooters, reported it had sold 8.5 million private versus 1.5 million shared e‑scooters by 2022. In the United Kingdom, an estimated 360,000 private e‑scooters were bought in 2020. New Zealand Statistics reports roughly 400,000 e‑scooters were imported from 2018 to 2023. One can assume, then, that private e‑scooters similarly outnumber shared e‑scooters in Australia. And the distinction between rental and private e‑scooters is an important one in the debate about safety. Media reports on shared e‑scooters in Melbourne have concentrated on two key subjects: launching trials and safety. Recent coverage refers to significant incidents and injuries. This creates a perception that e‑scooters are much less safe than other transport modes. Regulated shared e-scooters are safer The first thing to note is these reports don’t distinguish between shared and private e‑scooters. This matters because the shared e‑scooter market is highly regulated in Australia. Their operators are required to: provide helmets for riders apply speed limiters so they don’t exceed safe speeds geo-fence e‑scooters to limit where they can travel use pedestrian-detection technology. In contrast, private e‑scooters are not registered. They have different quality specifications and can have larger motors, often exceeding regulated engine outputs that vary from state to state. Importantly, private e‑scooters lack the advanced technologies used on shared e‑scooters to monitor rider use. There is little to no regulation or quality control over the private e‑scooters Australians can buy. Some models seen on the streets can exceed the legal speed limit. All that’s stopping them speeding is rider responsibility and police oversight. Hospitals records of e‑scooter injuries do not distinguish between private or shared e‑scooter riders. That’s also true of injury reporting and statistics, due to the way authorities collect crash statistics. Yet reported injury statistics for New Zealand indicate that the rate of serious injury while using a shared e‑scooter points is lower than for other modes of transport. Far more people suffered soft tissue injuries from rollerskating and skateboarding (5,344) than from riding e‑scooters (1,119), for instance. Nine times as many bike riders incurred a head injury or concussion (681) compared to e‑scooter riders (76). Better infrastructure is also vital for e‑scooter safety. A 2020 International Transport Federation (ITF) report found 80% of e‑scooter crashes occurred at intersections, and 70% during the day. The findings are not surprising when scant attention has been paid to delivering safe e‑scooter infrastructure. In Melbourne, for example, some lanes available for e‑scooter riding end abruptly. E-scooters cut emissions and congestion The most important issue arising from the City of Melbourne’s ban is the role e‑scooters (and e‑bikes) can play in shrinking cities’ huge carbon footprints. In addition, e‑scooters can: reduce traffic congestion improve access to public transport provide more efficient transport for shorter trips remove the need for car parking improve air quality. The City of Melbourne pointed solely at the safety concern to justify its ban. The city instead needs more proactive policies to integrate shared e‑scooters into the its mobility mix. This would have delivered all the public good of this transport mode. Governance is a neglected issue Much of the research on e‑scooters in cities focuses on sustainability and safety. Governance (policies, rules and regulations) is largely overlooked. Operating governance structures are established following a traditional operator licensing pathway. This approach is now being questioned. What has been lacking is broad engagement with all stakeholders, including the public. The focus should be on balancing the benefits and burdens of shared e‑scooters. E‑scooters are a particularly valuable form of transport for young people and those on low incomes or with a disability. The social justice they provide has been neglected. Predictably, then, the focus has been on the burdens, including safety. Another problem is the widely varied approaches around Australia to regulating e‑scooters. There isn’t even a consistent definition of e‑scooters. It appears governance decisions, which include ending operator licences, aren’t using reliable evidence to avoid knee-jerk reactions. For widespread sustainable and safe e‑scooter use, there needs to be: better governance and rider safety education more consistent and specific recording of e‑scooter incident and injury data an appreciation that riders are vulnerable road users who deserve safe infrastructure. A comprehensive, inclusive assessment of benefits and burdens is needed. We may then establish more clearly the sustainability and equity benefits, manage the safety concerns and arrive at more consistent policies and definitions across Australia.

Here's how a chef and mixologist husband-and-wife team are aiming towards a "sustainable future"

The culinary couple discuss zero-landfill bar programs, sustainability and the wide world of fish cookery

Southern food can be mean something immensely different from person to person. For chef-restauranteur Sammy Wiggins and his wife, mixologist Kassady Wiggins, their focus is pulled towards the coasts. The authors of a new cookbook "Salt & Shore: Recipes from the Coastal South" and owners of the restaurant Joyce in Los Angeles, the duo is passionate about highlighting the best that the coastal south has to offer, as well as prioritizing zero-waste cocktails and highlighting sustainability. As they told me, "We wanted to create a culinary narrative that respects the past and looks forward to a sustainable future." With far-reaching intentions as well as unique ingredient usage, dishes intended for communal and convivial enjoyment and great recipes for cooks who aren't especially well versed in the realm of fish, Monsour and Wiggins are excellent advocates not just for food and cooking at large, but also environmental rights, sustainability, fighting overfishing and the wonder of working with a spouse. You can purchase Salt & Shore: Recipes from the Coastal South here.  Salt & Shore: Recipes From The Coastal South by Sammy Monsour and Kassady Wiggins (Weldon Owen / Simon & Schuster) The following interview has been lightly edited for clarity and length. I love how this book embodies precisely how it's labeled: the perfect mix of "salt and shore," both entirely Southern yet totally coastal-based. Can you explain a bit about the development of the book?  The development of "Salt and Shore" was a deeply collaborative and immersive experience. We aimed to capture the essence of Southern coastal cuisine by blending our personal experiences, various regional histories and contemporary culinary techniques. We hope while flipping through the pages, readers get a sense of our shared love for the ocean and the bounty it provides.  How would you define the ethos of “Salt and Shore?”  The ethos of “Salt and Shore” is about honoring the rich culinary traditions and history of the Southern coast while embracing sustainability and innovation. It’s a celebration of the diverse ingredients from the shorelines, the vibrant communities and the time-honored practices of Southern hospitality. We wanted to create a culinary narrative that respects the past and looks forward to a sustainable future. Is "coastal southern" your general approach, from the cookbook to your restaurants to home cooking?  Yes, "coastal southern" is a central theme in our cookbook, restaurants and home cooking. It’s a cuisine that’s deeply rooted in the traditions of the South but is also heavily influenced by the coastal environment. This approach allows us to highlight fresh, locally sourced seafood and seasonal produce; creating dishes and drinks that are both comforting and contemporary. A central theme you’ll see throughout the cookbook is also recognizing the huge and ever-evolving impact other food cultures have had on “coastal southern” cuisine and (of course) in our very own home.  How do you think your backgrounds influenced your current food perspective, both personally and professionally? Our backgrounds have significantly shaped our food perspective. Growing up in the South, we were both influenced by the region's rich culinary heritage and the importance of community and hospitality. Sammy’s Lebanese roots inspire flavors and techniques in the kitchen, while Kassady’s African American heritage fuels her commitment to social justice and sustainability. Professionally, our experiences in various kitchen/restaurant settings and our commitment to sustainability have driven us to create dishes and drinks that are not only delicious but also mindful of their environmental impact. Sammy Monsour and Kassady Wiggins (Photo courtesy of Ziv Sade and Sammy Monsour) I am so interested by the section in the book about algae and microalgae in drinks. I also saw chlorella in the Pawleys Island Palmer. Can you elaborate a bit on that?  Incorporating algae and microalgae into drinks is part of our commitment to sustainability and innovation. Chlorella in the Pawleys Island Palmer, for example, adds a unique flavor and a boost of nutrients. In the Blue Bayou, blue spirulina adds a depth of flavor unattainable by any other means. These ingredients not only offer health benefits but also reflect our connection to the ocean and our desire to use diverse, sustainable ingredients in creative ways. "Fish Camp ''is so fun. I love the name of the chapters/categories and the convivial, social nature of those fish fries. Can you speak a bit to that? The "Fish Camp" section is inspired by the traditional fish fries and social gatherings that are a staple in Southern culture. It’s about bringing people together to enjoy simple, delicious food in a convivial atmosphere. The name and the concept are meant to evoke a sense of nostalgia and community, celebrating the joy of shared, easy-going meals and good company. I also enjoyed the "stock market" section, with such deeply flavorful, almost home-y dishes, from perloo to gumbo. I wonder if ostensibly more involved, storied dishes like that  are sometimes intimidating for cooks? What are some tips you can give for people looking to cook those dishes? While dishes like perloo and gumbo might seem intimidating, they are all about layering flavors and taking your time. Our tips for home cooks include starting with high-quality ingredients, following the steps carefully and not being afraid to make the recipe your own. These dishes are meant to be comforting and home-y, so don’t stress about perfection—enjoy the process and the results. We want these dishes to taste (and feel) good to you at every step, much more than we want them to be “perfect.”  What do you think are some of the best ways for the most fish-averse cooks to get into the realm of fish cookery? For those new to fish cookery, we recommend starting with some of the more iconic, approachable dishes from our "Hand Held" and "Fish Camp" chapters. These recipes are designed to be fun, social and relatively easy to prepare. Dishes like blackened fish tacos, our various fish “burgers,’ or our numerous styles of fish fry are great entry points. They offer familiar flavors and straightforward techniques that build confidence. Plus, they capture the convivial spirit of coastal Southern cuisine, making the cooking experience enjoyable and rewarding. How do you recommend reducing food waste for home cooks? Reducing food waste at home involves planning meals, using leftovers creatively and composting scraps. We also encourage home cooks to embrace the whole ingredient, such as using fish bones for stock or vegetable peels for broths. Being mindful of portions and storage can also help minimize waste. There are quite a few tips on this in the “Libations” chapter—as syrups and ice are an easy way to mitigate a lot of what we think of as food waste. You're both advocates for environmental rights and sustainability in the kitchens. Can you speak a bit to that?  Our advocacy for environmental rights and sustainability is a core part of our culinary philosophy. In our professional kitchens (and home kitchen), we have always prioritized sourcing sustainably, minimizing waste and educating our team and customers about the importance of protecting our natural resources. We believe that every small effort counts towards a larger impact on the environment. How can home cooks help mitigate environmental damages? Home cooks can mitigate environmental damage by supporting local farmers and fishers, choosing sustainable ingredients and trying to reduce waste. Simple actions like composting, using reusable bags and containers and being mindful of water and energy use in the kitchen can make a significant difference. Charleston Perloo (Photo courtesy of Ziv Sade and Sammy Monsour) Is there a standout recipe for the both of you in the book?  A standout recipe for us is the Charleston Perloo, which also graces the cover of the book. This dish is a quintessential example of Southern coastal cuisine, combining rice, seafood and a rich, flavorful broth. It’s a celebration of the Lowcountry's bounty and culinary traditions. The perloo embodies the heart and soul of "Salt and Shore," blending simplicity with depth and history. It’s a dish that’s both comforting and elegant, perfect for showcasing the vibrant flavors and communal spirit of Southern coastal cooking. The pecan salsa matcha with the grilled tilefish sounds stupendous! How did that component come together?  The pecan salsa macha is inspired by traditional Mexican salsa macha, which is known for its rich, nutty and spicy flavors. We wanted to bring a Southern twist to this classic by incorporating pecans, a staple in Southern cuisine. The combination of toasted nuts, dried chilies and aromatic spices creates a complex, robust sauce that perfectly complements the grilled tilefish. This dish exemplifies our approach of blending diverse culinary traditions to create something uniquely Southern and coastal, while paying homage to the vibrant flavors of Mexican cuisine. I love fish in all iterations, but do you think there's a certain cooking methodology that lets the favor of the fish shine most? Raw? Grilled? Fried?  Each cooking method brings out different qualities in each species or variety of seafood. Raw preparations like ceviche highlight the freshness and natural flavors, while grilling adds a smoky depth. Frying offers a crispy texture that many enjoy. The best method depends on the type of seafood and the desired flavor profile, but ultimately, the simplest methods often let the seafood shine the most. As with many a seafood cookbook, there are no desserts. Did you contemplate adding any or did you want to steer clear since there would (most likely) not be any actual fish in those dishes?  Instead of focusing on desserts, we dedicated an entire chapter to cocktails. We believe that a thoughtful libation sets the tone for the meal and it’s a Southern tradition to welcome guests with a cocktail. This approach aligns perfectly with Kassady’s specialty and her way of expressing creativity. By emphasizing pre-dinner drinks, we provide a unique and engaging start to the culinary experience. While many cookbooks end with dessert, we chose to highlight the importance of the welcome libation, ensuring that every meal begins with a touch of Southern hospitality and sets the tone for the rest of the meal. Can you speak a bit to the current state of overfishing?  Overfishing remains a significant global challenge, threatening marine ecosystems and the livelihoods of those who depend on them. However, it's important to recognize and celebrate the progress made in the United States. Thanks to the science-based regulatory framework provided by the Magnuson-Stevens Act, we've been able to recover our overfished stocks and are now global leaders in wild fisheries management. This act ensures that our fisheries are managed sustainably, balancing environmental, economic and social objectives. It’s a testament to what can be achieved with robust regulations and dedicated conservation efforts and it offers a hopeful model for addressing overfishing worldwide. Tell me a bit about your new LA restaurant, Joyce? The menu is amazing  Joyce is a celebration of elevated Southern coastal cuisine with a modern twist. The menu features a zero-landfill cocktail program, sustainably sourced seafood, locally grown produce and inventive dishes that honor tradition while pushing culinary boundaries. It’s a place where guests can enjoy the flavors of the coast in a welcoming, vibrant setting.   Want more great food writing and recipes? Subscribe to Salon Food's newsletter, The Bite. Could you explain what exactly a zero-landfill bar program is? Does it also offer non-alcoholic drinks?  A zero-landfill bar program means that we aim to produce no waste that ends up in landfills. This involves composting organic waste, recycling materials and using sustainable, reusable, or biodegradable products. We’ve developed creative ways to mitigate waste, finding secondary uses for produce that’s past its prime—whether bent, broken, bruised, blemished, or overly ripe. It also involves a lot of communication and cross-utilization with the kitchen. We try to mirror flavors on both sides of the menu. Take, for example, our Mother of Pearl Martini—we roast the top shells of oysters and make a vodka infusion with them and we make an in-house vermouth with past-its-prime white wine, ogo algae (that you can also find on our Ogo Ceaser salad) and lemon peels that have been expressed for another cocktail garnish.  Other ways in which we “close the loop” are through syrups, infusions, shrubs, tinctures and bitters. Additionally, we offer a range of non-alcoholic drinks crafted with the same care and creativity as our cocktails, ensuring that all guests have delicious, eco-friendly options. This program reflects our commitment to sustainability and innovation, making every aspect of our bar as environmentally friendly as possible. Could you both speak to the notion of working so closely with a spouse, both in terms of the book and the day-to-day in the restaurant?  Working closely with each other over the past eight years has been rewarding. It allows us to share our passion for food and sustainability, collaborate creatively and support one another. While it comes with its challenges, the key is communication, respect and finding a balance between our professional and personal lives. Sea Scallops (Photo courtesy of Ziv Sade and Sammy Monsour) What is a formative cooking memory?  Sammy here. One of my most formative cooking memories is growing up with my Taita, my Lebanese grandmother, who was an amazing cook. She would prepare elaborate feasts featuring freshly made pita bread, stews, hand pies, rice dishes and pastries, all from our homeland where she was born and raised. Helping her make hand pies and spending time with her in the kitchen are some of my earliest, fondest memories. My family celebrates her life and legacy through her treasured recipes, which I cook often at home. It's also Kassady's favorite cuisine for me to cook for her at home. This connection to my Lebanese heritage through cooking allows me to honor my family's traditions and care for my loved ones, keeping Taita's spirit alive in every dish. Both of our families talk about food before anything when getting together; everything is planned around food. Formative cooking memories for us involve helping our families prepare large, communal meals during holidays. These experiences instilled in us the importance of food in bringing people together and the joy of sharing a meal with loved ones. They also taught us the value of hard work, patience and the love that goes into cooking and ultimately nourishing one another. Why do you cook?  We cook because it’s our way of expressing creativity, nourishing loved ones, connecting with others and honoring our heritage. It’s a form of art and a means of storytelling that allows us to share our passion for food and sustainability with the world. Cooking brings us joy and fulfillment and it’s our way of making a positive impact. What are your top three favorite ingredients to work with?  Asking us to choose a favorite child? Broadly, our favorite ingredients to work with are unique spices, grass-fed butter, fresh seafood and seasonal produce. These elements allow us to create dishes that are vibrant, flavorful and reflective of the diverse culinary traditions we cherish. How do the two of you handle menu development, linking the bar program and the food menu so intrinsically?  When developing our menus, we start with the seasonal and sustainable ingredients available to us, ensuring that both the food and beverage components highlight the best of what each season has to offer. We brainstorm dishes and cocktails that complement these ingredients while creating a harmonious and cohesive dining experience. Linking the bar program with the food menu involves crafting flavor profiles that enhance and balance each other, ensuring that every bite and sip is part of a unified culinary journey. Our aspiration is to create food and beverages that are delicious, beautiful, crave-worthy and soul-satisfying. We believe that every element, from the welcome cocktail to the final dish, should contribute to an unforgettable dining experience. This holistic approach allows  us to express our creativity fully and ensures that our guests enjoy a seamless and delightful blend of flavors and aesthetics. Read more about this topic

How sustainable is your weekly grocery shop? These small changes can have big benefits

"The last thing we want to do is take the pleasure away from eating"

You might think eating more sustainably requires drastic changes, such as shifting to a vegan diet. While a plant-based diet is undeniably good for the Earth, our new research shows modest changes to your eating habits can also have significant environmental benefits. We assessed how food products on Australian supermarket shelves stack up against key environmental indicators, such as carbon emissions and water use. We found swapping the most environmentally harmful foods for more sustainable options within the same food group, such as switching from beef burgers to chicken burgers, can significantly reduce carbon emissions – by up to 96% in some instances. The last thing we want to do is take the pleasure away from eating. Instead, we want to help consumers make realistic dietary changes that also help ensure a sustainable future. So read on to find out which simple food swaps can best achieve this.   Informing sustainable diets The environmental impact of foods can be estimated using an approach known as a life-cycle assessment. This involves identifying the "inputs" required along the food supply chain, such as fertiliser, energy, water and land, and tracking them from farm to fork. From this we can calculate a product's "footprint" – or environmental impact per kilogram of product – and compare it to other foods. Most studies of environmental footprints focus on the raw ingredients that make up food products (such as beef, wheat or rice) rather than the packaged products people see on shelves (such as beef sausages, pasta or rice crackers). Of the studies that do focus on packaged foods, most only consider a fraction of the products available to consumers. What's more, a lot of research considers only the carbon emissions of food products, excluding other important measures such as water use. And some studies use global average environmental footprints, which vary significantly between countries. Our research set out to overcome these limitations. We aligned environmental footprints with the products people find on supermarket shelves, and covered a huge range of food and beverage products available in Australia. We also included many environmental indicators, to allow a more complete picture of the sustainability of different foods.     What we did Key to our research was the FoodSwitch database, which compiles food labelling and ingredient data from images of packaged food and beverages. It covers more than 90% of the Australian packaged food market. We combined the database with a mathematical method that sums the environmental impact of ingredients, to quantify the footprint of the product as a whole. From this, we estimated the environmental footprint of 63,926 food products available in Australian supermarkets. We then simulated the potential benefits of making "realistic" switches between products – that is, switches within the same food category.   Our findings The results show how making a small dietary change can have big environmental consequences. For a shopping basket composed of items from eight food groups, we simulate the benefits of swapping from high-impact towards medium- or low-impact food products. Our analysis assumes a starting point from the most environmentally harmful products in each food group – for example, sweet biscuits, cheese and beef burger patties. A shift to the medium-impact foods for all eight items – such as a muffin, yoghurt and sliced meat – can lead to at least a 62% reduction in environmental impact. Shifts towards the most sustainable choice for all items – bread, soy milk or raw poultry – can achieve a minimum 77% reduction. This analysis ends at the supermarket shelves and does not include additional food processing by the consumer. For example, raw meat will usually be cooked before human consumption, which will expand its environmental footprint to varying degrees, depending on the method used. See the below info-graphic for more detail. The full results are available in our study. What next? Many people are looking for ways to live more sustainably. Insufficient or complex information can fuel confusion and anxiety in consumers, leading to inaction or paralysis. Consumers need more information and support to choose more sustainable foods. Supermarkets and retailers also have an important role to play – for example, by giving sustainable products prominent shelf placement. Attractive pricing is also crucial – particularly in the midst of a cost-of-living crisis when it can be difficult to prioritise sustainability over cost. Government interventions, such as information campaigns and taxing high-impact products, can also help. Food labelling is also important. The European Union is leading the way with measures such as the eco-score, which integrates 14 environmental indicators into a single score from A to E. Apps such as ecoSwitch can also empower consumers. The diets of people in developed nations such as Australia exert a high toll on our planet. More sustainable food choices are vital to achieving a sustainable future for humanity. We hope our research helps kick-start positive change.
