Help support the Climate and Ecology Bill

The Climate and Ecology Bill was first introduced by Caroline Lucas MP as a private members’ bill in September 2020. It has been written with world-leading scientists to tackle the full extent of the climate and nature crisis in line with current science. Its purpose is to ensure the UK takes full responsibility for its part in limiting global warming to below 1.5 °C and reversing the destruction of nature, within its borders and across the world. The Bill will involve the public, through a science-led Climate and Nature Assembly, to help create a strategy that will be presented to Parliament and move us forward in a fair way to achieve the transformative change we so desperately need.

Supporters of the Bill so far number 8 Political parties, 35 Peers, 120 MPs, 193 Councils, 92 Scientists, and over 500 organisations including CIEEM, The Wildlife Trusts, Zoological Society of London (ZSL), British Trust for Ornithology, Whale and Dolphin Conservation, Amphibian and Reptile Conservation, The Co-operative Bank, Lush, National Education Union, Friends of the Earth, as well as many local climate networks and campaign groups.

Most recently, Mayor of London Sadiq Khan publicly endorsed the Bill, while youth campaigners were successful in calling on Peers to progress the Bill ahead of its second reading in the House of Lords where it is sponsored by Lord Redesdale. It is now continuing on its journey to becoming law with its Lords Committee stage set for this October and re-tabling in the Commons in the Autumn.

With the UK reaching 40 °C for the first time in recorded history two weeks ago and as wildfires burn across Europe, Northern Africa and the United States, it is now more than ever critical we get emissions under control in line with 1.5 °C and restore nature to help us mitigate and adapt to the impacts of climate change.

The campaign is looking for scientists and environmental professionals to support the Bill. If this is of interest to you please contact Simon Oldridge, Science Liaison, at

Alternatively, you can sign up as an individual supporter, and/or you can write to your MP calling on them to back the Climate and Ecology Bill.
