Reducing Food Emissions through Plant-Forward Meals

Columbia Dining is committed to reducing emissions through strategic, plant-forward menu planning and procurement. Columbia Dining partners with the Office of Sustainability to track food purchases and determine the carbon footprints of their menus using the CoolFood Calculator, a resource created by the World Resources Institute (WRI).

1. Procurement Data  

  • Our team is gathering procurement data from Columbia Dining’s food purchasing partners, including Sysco and other small vendors. This data is then categorized into various segments to facilitate input into the CoolFood Calculator. The CoolFood Calculator converts all the kilogram amounts of food into metric tons of CO2 emissions for comprehensive analysis and tracking. converts all the kilogram amounts of food into metric tons of CO2 emissions for comprehensive analysis and tracking.
  • 2023 has been established as a baseline year.  

2. Menu Planning  

  • The Dining culinary team has set a target for 50% of items in every meal to be plant-based.  

3. Annual Targets   

  • Established annual targets to reach the 25% reduction by 2030.
  • Team will assess results and adjust approach as needed.
  • John Jay is the first dining hall to participate in the initiative. Learnings will subsequently be applied to other residential dining locations.  

During the Fall 2023 semester, Columbia Dining and the Office of Sustainability partnered with students in the Climate School on a capstone project that measured emissions from the procurement of food in John Jay dining hall. The students found that red meat comprises just 13.4% of purchased products but accounts for 72% of Columbia Dining's total carbon footprint. Their recommended action plan included committing to the Plant-Powered Carbon Challenge. 

The Plant-Powered Carbon Challenge was an initiative of the NYC Mayor’s Office aimed at reducing carbon emissions through a plant-forward procurement strategy.  

Columbia Dining was the first organization to sign on to the challenge, announced on December 5, 2023. As part of the challenge, Columbia Dining committed to reducing its food-based carbon emissions by 25% by 2030. 

Participants in the Plant-Powered Challenge were given guidance from Greener by Default, a research-backed strategy group. 

The recommended approach was to gradually offer sustainable choices for student diners to make, without taking other options off the menu. Where and when possible, plant-based foods will be integrated into regular features or offered as the default choice, while continuing to give diners the option for meat or dairy. 

Columbia Dining is committed to serving delicious food and preserving student choice. We’re not taking anything away, just adjusting the role meat plays in our meal planning.   

For example, look for plant-based menus as a regular feature at traditional stations, or as the primary menu with optional meat additions. The team is also baking in-house vegan desserts. 

The early findings were incredibly promising. In just a few months, John Jay achieved a notable reduction of 12% in emissions specifically from beef, a remarkable step in the journey towards an overall campus reduction of 25% reduction by 2030.
