Thursday Webinar: Major U.S. Climate Coalition Calculates America’s ‘Fair Share’ of Climate Action

Advocates Call for Transformational Domestic, International Action by United States

WASHINGTON— A new analysis finds that the United States would need to reduce greenhouse gas emissions by an amount equivalent to 195% of its 2005 emissions levels by 2030 in order for the U.S. to contribute its “fair share” to global action on climate change.

The United States Climate Action Network (USCAN) proposes that the U.S. meet part of its fair share by reducing domestic emissions 70% by 2030 and meet the balance by supporting emission reductions overseas.

The analysis, titled The U.S. Climate Fair Share to Limit Global Warming to 1.5 Degrees, was developed by a USCAN working group led by ActionAid USA, North Carolina Interfaith Power and Light, the Center for Biological Diversity and EcoEquity.

The fair shares challenge figures prominently in the international effort to limit warming to 1.5 degrees Celsius, as many observers find it implausible that other countries would make up for shortfalls in the U.S. contribution to meeting the goals of the Paris Agreement. If the U.S. does not do its fair share, the world will not achieve the Paris temperature goals.

On Thursday, Dec. 3, the authors of the analysis will host a webinar for journalists to discuss the findings and their implications for the incoming Biden administration.

When: Thursday, Dec. 3, at 1 p.m. ET/10 a.m. PT

Background: The USCAN analysis is part of a broader international effort to quantify individual countries’ fair shares of global climate action, an effort endorsed by hundreds of organizations around the world, which can be found at

The U.S. Climate Action Network (USCAN) is a vital network for 175+ organizations active on climate change. Their mission is to build trust and alignments among members to fight climate change in a just and equitable way. They envision a powerful, inclusive, and trusting network of U.S. organizations who worked together to meet the global goals in the Paris Climate Agreement and exceed the U.S. targets outlined in that agreement.

The Center for Biological Diversity is a national, nonprofit conservation organization with more than 1.7 million members and online activists dedicated to the protection of endangered species and wild places.
