Ambitious Climate Action

The Race to Zero – Leading with Climate Science

ICLEI150 is a movement of local governments across the ICLEI U.S. network stepping up to join the Cities Race to Zero to cut global emissions in half by 2030 and to zero by 2050.

Respond to the moment. Be recognized for real action.

ICLEI150 is ICLEI’s long-term commitment to helping you achieve your 2030 target and then your climate neutrality by 2050.

The Race to Zero

Race To Zero is a global campaign (established Fall 2020) to rally leadership and support from businesses, cities, regions, investors for a healthy, resilient, zero carbon recovery that prevents future threats, creates decent jobs, and unlocks inclusive, sustainable growth.

The objective is to build momentum around the shift to a decarbonized economy ahead of COP26 (November 2021), where governments must strengthen their contributions to the Paris Agreement. This will send governments a resounding signal that business, cities, regions and investors are united in meeting the Paris goals and creating a more inclusive and resilient economy.

The Cities Race to Zero is a collaboration between ICLEI, C40 Cities, Global Covenant of Mayors, CDP, UCLG, WRI and WWF.

Pledge to Meet the Climate Crisis

ICLEI Will Report Your Pledge

Pledges bring both recognition and accountability—but they must urgently be followed by action. 

Set 2030 Science-Based Target

ICLEI Will Provide and Report your Target

If you have a complete 2016 or newer community greenhouse gas inventory, ICLEI’s technical experts will calculate your science-based target (SBT). This target is the level of emissions your city or county must reduce to achieve your fair share of the Paris climate goals.

If you do not have an applicable inventory, ICLEI will help you create or update it.

Science-Based Targets are calculated climate goals, in line with the latest climate science, that represent your community’s fair share of the ambition necessary to meet the Paris Agreement commitment of keeping warming below 1.5°C. To achieve this goal, the Intergovernmental Panel on Climate Change (IPCC) states that we must reduce global emissions by 50% by 2030 and achieve climate neutrality by 2050. Equitably reducing global emissions by 50% requires that high-emitting, wealthy nations reduce their emissions by more than 50%.

Calculating the target requires the following inputs:

  • Your community’s GHG emissions inventory (between 2016 and 2019)
  • Your community’s current and projected population growth
  • The United States’ Human Development Index (HDI)
  • The planetary emissions carbon budget available to limit global temperature rise to 1.5°C above pre-industrial levels. This is the level of maximum warming recommended by the IPPC and agreed to by 195 country-signatories of the Paris Climate Agreement.

Science-Based Targets build internal and external support to achieve the target and boosts public confidence in local climate action. They show local governments what they need to do by 2030 and 2050, spurring innovation and collaboration.

Act Now: High Impact Action

ICLEI Will Identify and Report Community-Specific High Impact Actions

Using your community’s 2030 science-based target and greenhouse gas profile, as well as our knowledge of your community priorities, ICLEI’s technical staff will meet with your team to develop high-impact actions to achieve the 2030 target. 

Once identified, ICLEI will provide technical assistance and workshops to help your team begin implementation.

ICLEI’s Carbon Neutrality Framework and ClearPath planning module will support high-impact actions. ICLEI will draw from and leverage our partners, including American Cities Climate Challenge, America’s Pledge, C40 Green and Just Recovery, Project Drawdown, and many others. 

ICLEI150 participants are invited to participate in ICLEI’s technical assistance workshops targeting high-impact actions.  Topics may include building electrification, strategies for working with your utility provider, electric vehicle charging infrastructure, etc.

Let the World Know Your Progress

Reporting Will Develop Internal and External Support

Reporting your progress allows ICLEI and your team to co-develop the next steps in your journey. ICLEI will amplify your progress through its media and partner channels.
