CNCA Innovation Fund
The CNCA Innovation Fund was created in 2015 to invest in high-potential, city-led projects that develop, test, implement and amplify deep decarbonization strategies and practices. To date, the Alliance has invested $2.4 million in 27 early-stage innovation projects targeting transportation, energy-supply, buildings, and waste systems. These projects endeavor to accelerate deep decarbonization around the world by showing the "art of the possible" in urban climate change.
Carbon Capture, Storage, and Utilization
City Lead: Copenhagen
These publications mark the end of a one-year project carried out in collaboration between five climate vanguard cities, all members of CNCA: Amsterdam, Copenhagen, Helsinki, Oslo and Stockholm. A suite of background notes and reports have been developed that explore carbon capture storage and utilization technologies (CCSU), and the solutions they provide to cities. Until now, the discussion on carbon capture has rarely been mentioned in the context of cities.
