The Carbon Neutral Cities Alliance (CNCA) is a collaboration of leading global cities working to cut greenhouse gas emissions by 80-100% by 2050 or sooner — the most aggressive GHG reduction targets undertaken anywhere by any city. The 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. These cities collaborate to share lessons in planning for and implementing deep carbon reductions and opportunities to accelerate best practices in deep decarbonization. This is how they do it: Developing carbon neutrality planning and implementation standards, supporting deep decarbonization innovations, advancing transformative change in key urban sectors
