Climate change

Last updated December 10, 2020

Fighting climate change is one of the biggest challenges of the 21st century. To address this challenge, the city must reduce its greenhouse gas emissions considerably and become carbon-neutral over the next 24 years. This is a collective effort in which everyone must participate, including companies, organizations, governments and citizens.

Impacts on climate change

The impacts of climate change are apparent all over the world. In Montréal, heat waves and flooding are two very real consequences of climate change. 

According to the international scientific community, the rise of global warming must be limited to 1.5 °C to avoid the worst impacts. Our choices and actions in the coming years will be crucial.

Our commitments for the climate

Our objective is to reduce our greenhouse gas emissions by 55 per cent between now and 2030, and to become a carbon-neutral city in 2050.

How will we meet this objective?

We’ve created a climate plan, with 46 measures around transportation, street and green space development, reducing garbage/food waste and energy-efficient buildings.


The ecological transition is a collective effort. The city has made a commitment to tangible actions. Residents and companies; You can also do your part. 

Every action counts. Choosing active transportation, reducing food waste, planting trees, properly insulating your home and using an electrical heating system are some of the actions that have a big impact.
