Serving Plant-Based by Default in Colleges Can Cut Emissions by 24% and Meat Consumption by 81% – Here’s Why

A recent trial conducted at three college campuses in the US revealed that serving plant-based options as the default in cafeterias can lead to a significant decrease in meat consumption and greenhouse gas emissions. The study found that presenting only vegan dishes to students resulted in up to 81.5% more students choosing plant-based meals, leading to a 23.6% reduction in GHG emissions. Additionally, meat emissions are twice as high as plant-based foods, making the shift towards plant-based options beneficial for the environment.

The success of default plant-based options in changing eating habits relies on proper implementation by dining hall operators and staff. By making plant-based dishes the default option, campuses can encourage sustainable food choices and drive decarbonization efforts. The study also emphasized the importance of engaging staff, understanding audience preferences, and leveraging local food culture to increase satisfaction with plant-based dishes. Promoting defaults as part of climate action plans and providing support for on-site staff can help institutions adopt more sustainable dining practices.
