Quantifying the Impact of the Inflation Reduction Act on City Climate Actions and Goals: Methodology for Cities

Published in

In October 2022, C40 Cities and Climate Mayors published Climate Action and the Inflation Reduction Act: A guide for local government leaders to help mayors and their staff understand the opportunities within the IRA to advance climate goals.

This report, developed by C40 Cities, Bloomberg Associates, and Slipstream, provides guidance on how cities can evaluate the quantitative impacts of key provisions from the IRA to accelerate and support their carbon-reduction strategies.

This report builds on the methodology developed in partnership with the City of Chicago to create an Addendum to their Climate Action Plan (CAP), Impacts of the Inflation Reduction Act on Chicago's 2022 Climate Action Plan.
