Nearly 60 council leaders, representing 35% of the population have pledged to reach net-zero five years earlier than central government.
Warwick District Council, London Borough of Lambeth, St Albans City and District Council, Brighton & Hove City Council and Hammersmith & Fulham Council are among those who have pledged to meet net-zero early.
The pledge explicitly commits them to neutralising emissions by 2030 and those of their residents and businesses by 2045.
The 57 councils are part of UK100, a network for UK locally-elected leaders who are committed to play their part in the global effort to tackle climate change.
The network is pushing for more powers and resources from central government to enable them to take ambitius climate action.
Cllr Christopher Hammond, incoming Network Membership Director at UK100, said: ‘The fundamental challenge of our time is getting to net zero carbon emissions and averting climate breakdown.
‘It’s a task that will need bold leadership, legislative clarity, shifts in culture and behaviours, willingness to make mistakes and an enthusiastic adoption of new technologies.
‘I know from my time leading a city council that local government is uniquely placed to face and overcome these challenges. Not only do they provide services, but they have a unique sphere of influence. Fantastic things are already happening in county, city, town and village halls across the county.
‘UK100 is uniquely placed to galvanise, support and make an impact for its members. I look forward to joining this ambitious organisation and their passionate team at this important moment.’
Polly Billington, director of UK100, added: ‘These ambitious local leaders have pledged to do everything within their power to reach net zero emissions as soon as possible in a way that benefits their communities with new jobs and skills.
‘From Edinburgh to Cornwall local leadership, alongside funding and powers, is key to winning the race to net zero.’
