What is C40 UK?

C40 Cities Climate Leadership UK (“C40 Cities UK”) operates as part of the C40 Cities Network. The C40 Cities Network is headed by C40 Cities Climate Leadership Group Inc (“C40 Cities US”) in the United States. 

The C40 network is a network of the world’s megacities committed to addressing climate change. The aim of the C40 network is to support cities to collaborate effectively, share knowledge, and drive meaningful, measurable and sustainable action on climate change. The C40 network connects 94 of the world’s leading cities to take bold action to tackle climate change, leading the way towards a healthier and more sustainable future.

Role in the C40 Cities Network

C40 Cities UK plays a key role in the C40 network and delivers on its mission by working and leading on a number of projects, including:

Climate Action Planning (“CAP”)
C40 Cities US devoted additional resources to supporting cities in Latin America, South East Asia, and Africa to develop their climate action plans. So far, 73 cities have committed to tough climate targets to deliver and implement Paris compatible action plans by the end of 2020 and eight cities have published their action plans. The CAP programme is supported by C40 Cities UK staff in project management and administrative roles.

Women4Climate Tech Challenge
C40 Cities US launched the Women4Climate Tech Challenge as a competition designed to spark innovation and accelerate climate solutions from women in the tech community. In the framework of the Women4Climate initiative, the Tech Challenge is a key action for the C40 network to support and promote diversity and inclusion in technology and innovation, where women are largely underrepresented and provide to mayors the best women-led climate-focused tech solutions. The programme was delivered by C40 Cities UK and is funded by L’Oréal and the Michelin Corporate Foundation. 

Reinventing Cities
C40 Cities US launched Reinventing Cities as a competition designed to engage the private sector to propose innovative projects to drive carbon neutral and resilient urban regeneration on 39 selected sites in 15 cities. More than 230 expressions of interest were received from 1,200 companies and organisations and 82 finalists will compete in the final round. The programme was delivered by staff from both C40 Cities UK and C40 Cities US and is funded by Climate-KIC Holding B.V. and C40 Cities UK. 

Breathe London
C40 Cities US launched its first air quality monitoring programme called Breathe London. Supported by the Children’s Investment Fund Foundation, C40 Cities UK collaborated with the Greater London Authority on a new sensor project to better understand Londoners’ exposure to air pollution around the city. 

Cities Finance Facility (“CFF”)
The C40 CFF, work undertaken substantially by C40 Cities UK, continues to support cities to access financial resources. Following a rigorous and competitive process, C40 Cities UK selected nine cities to receive specialist financial advice and bespoke support from leading global experts over the next two years to develop sustainable infrastructure projects.
