Sadiq Khan,
Mayor of London Said...

"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."
