Climate Action BA

“Mayors across the world have the challenge of promoting climate policies that will help us create more resilient, sustainable and inclusive cities. The climate agenda is essential to generating opportunities for growth and promoting fair and sustainable development for everyone". Horacio Rodríguez Larreta

For years, the City of Buenos Aires has been a regional leader in the fight against climate change. The climate change agenda is at the heart of our government’s priorities, not least because it contributes to the quality of life of our residents, creating a healthier urban ecosystem.

In Buenos Aires, several government departments are actively involved in the development of our Climate Change Strategy. A fundamental component of this strategy is our new Climate Action Plan, developed with the support of C40 Cities and based around our commitment to achieving carbon neutrality by 2050.

Buenos Aires manages several active climate mitigation and adaptation policies.


Ecobicis - public bike share system

(200 stations)

100 new hectares of green public spaces (2016-2019).


Bicycle lanes


Modernization of devices for the separation and treatment of recyclable waste.


Pedestrian zones

(259 street blocks in the city centre)

100% led street lighting

(first city in LATAM)

Collective urban action is critical to advancing the climate goals of the Paris Agreement at the local level. Buenos Aires actively participates in international city networks that are committed to sustainable development and the fight against climate change.

Buenos Aires’ mayor, together with the mayor of Bogotá, was elected Vice President of C40 for Latin America in 2020, and is a member of C40’s Steering Committee. Within this framework, both cities launched the "Dialogue for Climate Action" joint initiative to encourage and support other cities in the region to develop ambitious climate goals.

Urban 20 (U20) 2020 is the G20 engagement group that represents the voice of cities. In 2020, Buenos Aires co-chaired (together with Rome) a Special U20 Working Group on Covid-19. Its objective was to analyze the challenges and responses of cities to the crisis unleashed by the pandemic, with a focus on the financing necessary for a green and fair recovery.
