Menu Nudges for Climate-Smart Events with Taylor Flores
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.
“Small menu changes can create major climate benefits without limiting choice.” Taylor Flores
Importantly, Flores noted that menu changes often produce larger carbon savings than other sustainability initiatives, such as reducing or eliminating single-use plastic, though these initiatives are important for other environmental and social reasons.
“We have been focusing for so long on how food is served, but not what food is served, even though the what is by far the larger source of emissions.” — Taylor Flores
This insight reframes sustainability planning for organizations. Reusable utensils and zero-waste initiatives still matter, but if climate impact is the goal, menu composition deserves equal—or greater—attention.
Six Behavioral Nudges for Climate-Smart Menus
Rather than promoting rigid rules, Greener by Default uses behavioral science to make sustainable eating feel natural and welcoming. Flores highlighted several practical techniques that event organizers can implement immediately.
- Plant-Based Defaults
The most effective strategy is surprisingly simple: make the plant-based meal the default while still allowing guests to opt into meat or dairy.
For example, a conference registration form might automatically select a plant-based entrée, with an optional checkbox for an animal-based alternative. Diners keep full freedom of choice, but research shows this subtle shift can dramatically influence decisions.
Key Takeaways
- Food choices often matter more than packaging for event-related emissions
- Plant-based defaults preserve choice while increasing sustainable selections
- Two plant-based dishes per meat option can normalize climate-smart eating
- Flavor-focused menu names make plant-forward foods more appealing
- Subtle ingredient swaps can reduce emissions without reducing satisfaction
“People are more than seven times more likely to order a plant-based meal from a menu that’s plant-based by default,” Flores explained.
- Climate-Friendly Ratios
When defaults are not practical, Flores recommends changing proportions.
Instead of offering one vegetarian entrée beside several meat dishes, organizations can aim for a two-to-one ratio: two plant-based choices for every animal-based option. This simple adjustment normalizes plant-forward eating and encourages guests to choose based on taste and appearance rather than identity.
“When menus shift from mostly meat options to mostly plant-based options, selection of plant-based meals can increase dramatically,” Flores noted.
- Subtle Substitutions
Some of the easiest climate wins happen quietly.
Switching dairy butter for plant-based butter, using oat milk creamers, or baking with plant-based ingredients often goes unnoticed by diners while improving inclusivity for people with allergies or dietary restrictions. Flores shared an example of a school district that saved thousands of dollars annually after replacing eggs and dairy ingredients in baked goods.
- Tasty Titles
Language matters.
Instead of labeling food “vegan,” “healthy,” or “meatless,” Flores encourages menu descriptions that emphasize flavor and ingredients. A “vegan pasta” becomes a “rosemary lemon chickpea pasta.” A “vegetarian hummus wrap” becomes a “roasted red pepper avocado hummus wrap.”
“Make sustainable meals inviting, delicious, and easy to choose.” Taylor Flores
Research suggests appealing names can increase plant-based food selection significantly because people respond to taste and curiosity more than dietary labels.
- Meat Reduction
Another practical strategy is serving smaller portions of meat in mixed dishes without eliminating it altogether.
Research cited by Flores found that reducing meat portions modestly—rather than drastically—can lower emissions while maintaining diner satisfaction. Blended dishes, such as mushroom-beef burgers or pasta sauces mixing vegetables with meat, also help reduce environmental impact while preserving familiar flavors.
- Designing for Inclusion
Throughout the discussion, Flores emphasized that climate-smart menus are also more inclusive.
Plant-forward meals can better accommodate lactose intolerance, religious dietary practices, health goals, and diverse food preferences. Importantly, her approach avoids judgment.
“We want to make sure there’s still at least one or two meat and dairy-based options available… to truly be inclusive.” — Taylor Flores
What Happens When Organizations Try It?
The ideas are not theoretical.
In 2024, Greener by Default partnered with sustainability media company Trellis (formerly GreenBiz) to redesign event catering using plant-forward ratios, tastier naming, and subtle substitutions. The result: more than 25,000 kilograms of carbon emissions avoided across events.
At a LinkedIn cafeteria pilot in San Francisco, shifting toward mostly plant-based entrées and making oat milk the default reduced food-related emissions by 50%, while diner satisfaction remained unchanged. Dairy consumption dropped substantially, and meat served per person was cut in half.
For Flores, these examples show that climate action can be practical, affordable, and inviting.
Practical Takeaways & Implications
Climate-smart menus do not require perfection—or persuasion campaigns.
Organizations planning meetings, conferences, or workplace meals can start small:
- Offer two plant-based choices for every meat option
- Rename dishes around flavor and ingredients
- Default to oat milk, plant-based butter, or dairy-free condiments
- Reduce meat portions by up to 25% in mixed dishes
- Make plant-based meals the default for RSVPs while preserving choice
- Focus on deliciousness and inclusion, not restriction
The broader lesson is hopeful: sustainability becomes easier when systems support better choices. Rather than asking individuals to overhaul habits overnight, event planners can redesign environments so climate-friendly decisions feel effortless.
As Flores reminded Earth Talks attendees, every meal matters—and every menu is an opportunity to make climate action more welcoming, joyful, and achievable.
