3Ci is an innovative collaboration of local government and the private sector.
Our mission is to support local authorities in securing the necessary long-term finance for achieving net zero.

We are creating a wider partnership, including UK Government, Innovate UK, Metro Mayors, Combined Authorities, Scottish and Key Cities, Counties and Districts and a growing league of private investors, financiers, advisors, developers and built environment technology professionals.
Achieving net zero is an urgent global challenge and government investment alone is not enough to achieve the transformation we need across our homes, businesses and infrastructure; enabling private investment will be critical.
3Ci, The Cities Commission for Climate Investment, is an innovative collaboration of local government and the private sector. Our mission is to support local authorities in securing the necessary long-term finance for achieving net zero.
3Ci is working to leverage the combined scale of cities and regions to mobilise finance and drive investment into low and net zero carbon projects across all local areas together, rather than individual ones. We believe this is the key to unlocking the investment so urgently needed.
Our place-based experience and ability to convene government, community, industry and financial institutions, makes us perfectly placed to help deliver the investment needed to get cities and regions to net zero – and get there fast.

LONDON REGIONAL INVESTOR EVENT
Thank you! 200+ Attendees 25 Speakers
“300 registered delegates coming to the Catapult, organised by the Greater London Authority, London Councils and our core team at 3Ci enabled us to have a conversation that is not otherwise possible almost anywhere in the world. We focused on combining the value of the place with the logic of capital so that local government and city wide government with pension funds, insurance companies, bankers and financial advisors can grasp the important task of investing in a liveable planet.” Prof Greg Clark CBE FAcSS, Chair of 3Ci (Cities Commission for Climate Investment) and Connected Places Catapult
The event hosted insightful conversations around the challenges and opportunities for local net zero projects, new funding models and the next steps in driving net zero investment in London.
