Ecocity World Summit is the pioneer global conference on sustainable cities. The hybrid physical-virtual summit will take place 6-8 June 2023 at the Barbican Centre. It will convene representatives from communities across the city from school children, academia and professionals to investors, trade associations and political leaders, to share new thinking and maintain the energy and momentum generated by COP26.

The bid to host the summit was supported by the UK Government, Mayor of London, London Councils, City of London Corporation, Transport for London, UK Green Building Council, Royal Town Planning Institute, Green Finance Institute and Bartlett Faculty of Built Environment, UCL.
It was led by New London Architecture (NLA) in partnership with London & Partners, the Barbican Centre and professional conference organisers MCI. Summit Director, NLA’s Amy Chadwick Till, will lead a programme committee of industry experts to shape and deliver the programme.
