Behavior science can make event food more sustainable—without taking away choice.
Food accounts for roughly 30% of global greenhouse gas emissions, yet conference organizers, nonprofits, and workplaces often overlook menus when planning sustainability efforts. In an Earth Talks presentation, sustainability professional Taylor Flores showed how simple behavioral nudges can dramatically lower the carbon footprint of meetings and events while keeping meals appealing, inclusive, and flexible.
Introduction
When organizations talk about sustainability, conversations often focus on recycling bins, reusable cups, or eliminating plastic straws. But according to Taylor Flores, one of the most powerful climate actions available may already be sitting on the lunch table.
Flores, Corporate Engagement Manager at Greener by Default, argues that the biggest environmental gains come not from changing how food is served, but what food is served. During her Earth Talks presentation, she shared a practical roadmap for reducing emissions at meetings, conferences, and cafeterias through small, evidence-based adjustments to menus—without requiring anyone to give up personal food choices.
The approach is refreshingly pragmatic: make plant-forward meals easier, more attractive, and more visible while preserving freedom of choice. Rather than forcing behavior, organizers can gently “nudge” people toward options that are healthier, more inclusive, and significantly lower in emissions.
Why Event Menus Matter More Than We Think
Many people underestimate food’s climate impact. Flores explained that plant-based meals generally produce about half the emissions of animal-based meals due to land use, methane emissions, and deforestation tied to raising livestock. In some cases, the difference is dramatic: plant-based alternatives can cut emissions by nearly 90% compared with conventional beef products.
