Food production alone could cause the world to miss its 1.5 degree Celsius climate target even if countries stop burning fossil fuels immediately. Along with energy, food production is one of the biggest contributors to global greenhouse emissions — one-quarter to one-third of emissions come from food systems.
Our World in Data identified five ways to reduce emissions from the food industry: adopting a plant-based diet; consuming healthy calories; limiting food waste; and improving crop yields and farming practices. Shifting to a plant-based diet would lead to the biggest reduction in emissions. If these practices were fully adopted by 2050, the world would see net negative emissions.
Both consumers and producers have significant roles to play in reducing food emissions that involve legislation, investment and creating better policies. Although fully incorporating these five methods into daily activity could be difficult, the changes would lead to “a global food system that is more productive, has a lower environmental impact, and provides a healthy, nutritious diet for everyone.”
