With people increasingly aware of the climate impact of their lifestyles, the spotlight is falling on the food we eat. Agriculture and related land-use account for nearly a quarter of global greenhouse gas (GHG) emissions. But not all foods are created equal, and plant-based foods are generally a lot less resource-intensive to produce than animal proteins. Take beef vs. beans: per gram of protein, beef production uses 20 times the land and generates 20 times the GHG emissions as beans.
Much attention is paid to unusual innovations aimed at offering a wider variety of food options with a smaller climate footprint — like crackers made from insects or algae protein bars. But large institutions that want to offer diners climate-friendly food options are finding it’s more straightforward than expected. That’s in part thanks to recent behavioral science research, which shows that small changes in menu language or creating delicious plant-centered dishes can greatly increase the uptake of sustainable offerings. In short, they’ve found it’s already possible to eat tomorrow’s climate-friendly diet today, through easy changes that don’t compromise on flavor or cost.
New data from the Cool Food Pledge — a group of restaurants, cities, hospitals and companies that have committed to cutting GHG emissions associated with the food they serve by 25% by 2030, in line with Paris Agreement goals — show that members were able to collectively reduce emissions by 4.6% overall and by 12% per plate in just four years. Some members have reduced emissions even more quickly, showing big changes are possible within a short time.
Food consumption in restaurants, workplace canteens and school cafeterias has fallen dramatically during the past year due to the COVID-19 pandemic and resulting lockdowns. While the industry begins to revive amid calls for a “green” recovery, these results can serve as inspiration, showing what could be achievable when the wider food service industry picks up again post-COVID. When diners return, food service operators should seize the chance to ensure strong and engaging sustainability credentials are at the center of their menu offerings. Offering more plant-rich options is key to hitting climate targets since as they are generally much less resource-intensive to produce.
So what does that mean for organizations serving food? And how feasible is it? Lessons from Cool Food Pledge members show that meaningful progress toward a sustainable food future is simple. It’s just a case of keeping the spotlight on what’s delicious, cost-effective and low-carbon.
Here are the three main lessons:
1. Make It Delicious.
Climate-friendly food doesn’t have to be dull. Take the example of biotech company Genentech, which has 10,000 staff based in California, and an in-house culinary team creating chef specials. When it joined the Cool Food Pledge it changed the chef specials to plant-rich options — serving up even more vegetables, pulses and grains. Some of the new dishes included “Vegan Jackfruit, Okra and Seitan Jambalaya” with brown rice, Creole sauce and shaved scallions as well as “Charred Yucatan Vegetables” with an array of vegetables, stewed black beans, habanero pickled red onions and flour tortillas. Following positive responses from employees, demand for the new plant-rich options grew while demand for the more traditional, meat-heavier options declined. Between 2018 to 2019 alone, the company reduced the climate impact of each plate of food it serves by an incredible 33%.
2. Keep It Cost-Effective.
Climate-friendly food doesn’t have to increase costs — and can even reduce them.
In the health care sector, at UCSF Health, forward-thinking chefs decided to couple a more climate-friendly ethos with a cost-effective one while feeding patients and visitors. UCSF had a 100% beef burger that wasn’t selling well, so switching to a 70:30 beef/mushroom blended burger in 2017 that sold better was a no-brainer. The Department of Nutrition and Health Services at UCSF Health realized the blended burger would cost less, the mushroom would ensure it remained flavorful and the reduction in beef would help UCSF Health hit its climate-friendly target for food.
At the same time, its central menu evolved from serving 20 entrees featuring beef in 2017 down to just three by 2020. This more plant-rich menu has proven both better for the climate and more appealing to customers. UCSF Health’s total food-related GHG emissions dropped by 13% in just three years, the biggest reduction amongst the health care members of the Cool Food Pledge.
3. Explore the World of Plants.
A welcome consequence of committing to a climate-friendly menu offering has been a surge in the quantity of vegetables, pulses and grains procured and served by member organizations. In fact, members purchased 12% more plant-based food items in 2019 relative to the base year. The University of Cambridge’s University Catering Service, which manages 14 cafés and canteens and caters for 1,500 events a year, has phased out ruminant meat completely, and guests can enjoy Swedish-style Vegballs, Smoky Moroccan Chickpea Stew and sweet potato burgers instead. Emissions dropped by more than 30% even as the university served 30% more food, reflecting the significant change in the ingredients that make up the meals it is serving.
Having an Impact Isn’t Rocket Science
This variety of progress reflects the distinct environments in which these organizations operate and the different diners they serve. Many are cutting emissions even as the number of meals they serve grows.
While every dining facility will have its own unique operations, the Cool Food Pledge is providing structure and guidance to help the food industry lower the carbon footprint of food in line with climate science. Members are guided through a three-steps of “pledge, plan, and promote”: they pledge to reduce food-related GHG emissions by 25% by 2030; they develop a plan to achieve their aims using the latest behavioral science; and by promoting their achievements, they are on the front lines of a growing movement that’s slashing the impact that food has on the climate.
