The UK Cities Commission for Climate Investment (3Ci) is a partnership between Connected Places Catapult, Core Cities, London Councils and a wide range of other private and public organisations.


3Ci adopts a novel approach to addressing the challenge of financing Net Zero in major cities across the UK. Through new research delivered by the 3Ci, we estimate that approximately £200 - £300 billion must be invested to achieve Net Zero across London and UK Core Cities. This is beyond the financing capacity of the public sector alone. 3Ci brings together the investment sector with cities to accelerate the opportunities for private finance to play a leading role in accelerating Net Zero infrastructure investment across commercial real-estate, housing, transport, renewable electricity generation, waste management and other green infrastructure

Cities are the engine of the global economy and home to a growing majority of the world’s population. In the face of increasing global challenges, from inequality to climate change, how can cities advance and inform more inclusive and sustainable models of urban development?

The Global Future Council on Cities 2023-2024 is focused on the urban affordability crisis – a widespread and multifaceted global challenge that highlights systemic injustices and deepens inequities. The Council curates and advances promising interventions that catalyse impact and action to address this crisis and can be used by public, private, and civil society stakeholders to drive change. be used by public, private, and civil society stakeholders to drive change

Cities have long been and will remain the fundamental engines of human progress. Today, 55% of humanity lives in cities, a number projected to grow to 60% by 2030. Just 600 cities fuel more than 65% of global economic growth, while 100 of them account for roughly 40%.

After two years of lockdowns, the Cities Council is focused on evaluating, tracking, and spurring a dynamic recovery from Covid in cities of the New Economy. Toward that end, the Council has launched the Dynamic Cities Framework, a guide for evaluating, tracking, and advancing the progress of New Economy cities as sustainable, vibrant, responsive hubs for talent and innovation. In 2022, the Cities Council is working to turn the Dynamic Cities Framework into an index, a set of metrics Cities can focus on to attract talent and enhance the lives of citizens.
