Copenhagen, 10 October 2019: Today, the World Business Council for Sustainable Development (WBCSD) joined forces with C40 Cities and CDP at the C40 World Mayors Summit in Copenhagen, to launch the City-Business Climate Alliance (CBCA).

In this new alliance, C40 Cities, CDP and WBCSD have joined forces to accelerate climate action and support cities and businesses to translate their global climate commitments into practical actions.

The CBCA was announced in a speech by the Mayor of Toronto, John Tory. The Alliance provides a model for how city governments and businesses across the world can break down barriers to cooperation and collaboration.

It connects cities and business to a global network of successful city-business partnerships, enabling peer-to-peer learning, and it supports cities at the local level to set-up new partnerships.

The launch comes with the publication of the City-Business Climate Alliance Guide showcasing successful examples from cities including Boston, London, Paris and Helsinki.
