Chicago Takes Action


Mayor Richard M. Daley unveiled the Chicago Climate Action Plan (CCAP), which outlined our plan to reduce local GHG emissions to 80% below 1990 levels by the year 2050.

To achieve this, Chicago must meet an interim target of 25% reduction below 1990 levels by 2020.

August 2015

Chicago joined the Global Covenant of Mayors for Climate and Energy (GCoM), the world’s largest cooperative effort among mayors to reduce GHG emissions, track progress, and prepare for the impacts of climate change.

As a signatory, we pledged to conduct a GHG emission inventory in compliance with the Global Protocol for Community-Scale GHG Emissions Inventories (GPC), the first global standard protocol under which cities can complete community-scale inventories.

Chicago was one of the first cities in the world to develop a GPC-compliant GHG emissions inventories for 1990, 2000, 2005 and 2010.

June 2017

Mayor Rahm Emanuel expanded efforts to reduce citywide GHG emissions to levels equivalent to or greater than 26-28% from 2005 levels by 2025.

December 2017

A group of over 50 international leaders convened at the North American Climate Summit to sign the Chicago Climate Charter, a cooperative agreement to mitigate climate change through advocacy, transparency, cooperation, policy, infrastructure planning, and collaboration at the municipal level.


We remain steadfast in our efforts to take action at the global, municipal and grassroots level. Sustain Chicago exists to provide local citizens the knowledge, tools and resources they need to do their part to reduce emissions and create a cleaner future for the generations ahead.
