London as a Host

London will host the first in-person Ecocity World Summit in four years, with the aim to make the 2023 edition the most impactful yet.

As one of the Top 10 Sustainable cities in the world, and the world’s first National Park City with 45% of the city as open green space, London provides a range of inspiring Ecocity principles in action. From sustainability-focussed developments and outstanding transport infrastructure to historical sites and attractions for delegates to visit, the capital is leading the way.

With London's commitment to becoming a net-zero carbon city by 2030, policymakers, activists, designers and academics have a crucial role in shaping the future of sustainable living.

Set against the London Festival of Architecture, the summit is bringing influential figures together to discuss urgent topics around city planning, sustainability, and urban lifestyles.

London and the C40

London is taking its role as a C40 city seriously. Home to some nine million people, the U.K’s Capital city is committed to making it a leader in the ecological future of our cities. Sadiq Khan, Mayor of London and current chairman of the C40 says, 

"Global cities have a big role to play in tackling climate change and environmental issues. London has shown its leadership by committing to a Green New Deal to help London become greener and fairer - creating new jobs and skills for Londoners and ensuring London becomes a net zero-carbon city by 2030 and a zero-waste city by 2050. It is fantastic news that London will be the host city for the Ecocity World Summit 2023."
