What does it mean for you as Mayor of London to now be the chair of C40, and how will this position help Londoners?

I am honoured to have been elected as chair of the C40 Cities network, representing nearly 100 cities from around the world As Chair I will focus on addressing inequality through a green and just transition, calling on national Governments to action, and tackling the twin challenges of air pollution and climate change. Cities have shown that they are the doers, not delayers, and are central to solving the climate crisis. London is playing a leading role in this with the ambition to be a zero-carbon city by 2030.

As a global city, London has strong historic bonds with many places around the world. By tackling the climate crisis, Londoners benefit from stronger, fairer economies, cleaner air and healthier communities, and greater equity around the world As C40 Chair, I will ensure London listens and learns from other cities, while sharing its success stories, , such as the Ultra Low Emission Zone and our work on the Green New Deal.
