Should New York City encourage residents to eat less meat and dairy to cut emissions?
New York City has released its first integrated greenhouse gas inventory that includes emissions from food production and consumption. The inventory found food is the third largest source of city emissions, behind buildings and transportation.
Why it matters
Including household consumption and goods produced outside the city gives a fuller picture of New York's carbon footprint than prior citywide measurements since 2005. It shows that eating more low-carbon foods such as fruits, vegetables, grains and legumes can reduce emissions.
Food accounts for 20% of New York City's overall emissions, ranking third behind buildings at 35% and transportation at 21%. The city has set a target to cut absolute carbon emissions from food purchases across city agencies by 33% by 2030.
The players
Mayor Eric Adams
Mayor Adams launched the Plant-Powered Carbon Challenge, urging leaders to reduce food-based emissions by 25% by 2030, and his office is set to formalize the city's commitments in a strategic climate plan.
C40 Cities
C40 Cities is a global network of mayors working on climate action, and New York signed its Good Food Cities Declaration in 2022.
The details
The inventory was developed by the Mayor's Office of Climate & Environmental Justice and is the first to include emissions from household consumption. It was modeled by EcoDataLab as part of a C40-coordinated project, and the city also signed the C40 Good Food Cities Declaration in 2022.
Timeline
2005: New York City began measuring citywide emissions.
2019/20: Meatless Mondays took effect in city public schools.
Early 2022: Plant-Powered Fridays were introduced in city public schools.
2030: Deadline for the 33% food purchase emissions reduction target.
Culture Shift
New York's inventory extends its 2022 signing of the C40 Good Food Cities Declaration by measuring food's emissions directly rather than only citywide sources. Like the Meatless Mondays rollout in city schools, it reflects a shift toward treating diet as a climate lever.
New Yorkers who eat more fruits, vegetables, grains and legumes can lower their household footprint, since food consumption is part of the city's emissions. Plant-based meals are already being served in city public schools and by NYC Health + Hospitals.
The takeaway
Shifting some meals toward plant-based foods is one of the more direct ways residents can reduce the emissions tied to what they eat, according to the city's findings. Small changes to weekly menus add up across a city of this size.
What happens next
The city's commitments will be formalized in Mayor Adams' strategic climate plan to be released later in April.
