On August 9, 2022, during a technical-political preparatory meeting for the C40 World Mayors Summit in Buenos Aires, the host city joined 17 cities worldwide in endorsing the call to action for a Plant Based Treaty and transformation of the local food system into a fair, healthy and sustainable one.

The Head of Government, Horacio Rodriguez Larreta who signed off on the endorsement said, “We are proud of our leadership on climate action. To promote the comprehensive well-being of people, now is the time to unite the mayors of Latin America and the world to promote faster and more ambitious action ahead of COP 27. Cities can achieve an enormous impact in the fight against climate change”.

In its 2050 Climate Action Plan, the City of Buenos Aires promotes sustainable food production through urban agriculture, healthy stations and the expansion of vegan markets. This effort, together with Law 6377 on urban agriculture enacted in 2020, supports a general increase in the consumption of foods with less environmental impact, moving away from unsustainable and unhealthy diets.

Plant-Based Treaty campaigner Stephanie Cabovianco said, “Considering that the City of Buenos Aires has a goal of carbon neutrality by 2050, and that according to C40, a change in the diet of cities could reduce emissions by up to 60% in just 10 years, we celebrate this step forward.”

Climate campaigners are now urging all C40 Cities to join the Plant Based Treaty initiative.


The Plant Based Treaty is modelled on the Fossil Fuel Non-Proliferation Treaty and inspired by treaties that have addressed threats such as ozone layer depletion. Since its launch in August 2021 the initiative has received support from 43,000 individual endorsers, 5 Nobel laureates, IPCC scientists, more than 800 NGOs and community groups, 700 businesses and 18 cities.

The global movement asking towns and cities to endorse the Plant Based Treaty to help pressure national governments to negotiate a global treaty that will:

  1. Halt the global expansion of deforestation attributed to animal agriculture.
  2. Incentivise a plant-based food system.
  3. Encourage public information campaigns about the benefits of plant-based foods.
  4. Free up land to rewild and reforest the Earth.
  5. Allow a just transition to more sustainable jobs, healthier people and a healthier planet.
