Carbon Neutral Cities Alliance

A project of the Urban Sustainability Directors Network

In partnership with INC and C40

A collaboration of international cities committed to achieving aggressive long-term carbon reduction goals.

Cities striving for carbon neutrality recognize that averting the worst impacts of climate change will require cutting GHG emissions by at least 80% by 2050. Because urban areas account for nearly three-quarters of humanity's emissions, reaching this goal will depend in large part on our ability to reimagine and reinvent cities in ways that promote economic prosperity, social equity, enhanced quality of life, and climate resilience.

The Carbon Neutral Cities Alliance (CNCA or “Alliance”) aims to address what it will take for leading international cities to achieve these deep emissions reductions and how they can work together to meet their respective goals more efficiently and effectively.

CNCA Framework for Long-Term Deep Carbon Reduction Planning

A core function of CNCA is to facilitate other cities’ understanding of how leading-edge cities are planning for long-term deep carbon reductions, and enable cities to take a more robust, consistent, equitable and comprehensive approach to carbon neutral planning and implementation. 

In 2015, we developed a streamlined Deep Carbon Reduction Planning Framework that provides a template for cities to use in developing their own plans, and identifies specific strategic challenges that cities continue to face in making further progress on carbon reduction. Based on the carbon neutrality plans developed by CNCA cities, the Planning Framework focuses exclusively on long-term and deep reductions, which require transformative rather than incremental approaches.

We also developed a companion Outline of the contents of a state-of-the-art "80x50" plan for reducing community wide greenhouse gas emissions by at least 80% by 2050 ("80x50").

Released December 2015

Infographic: How Much is Spent on Fossil Fuels in Cities 

CNCA has worked with five U.S. cities to create an infographic showing how much the citizens, businesses and municipal government spend on fossil fuels every year, where it goes and what it could otherwise fund if it were instead invested in the city's clean energy future.
