In the month that has been confirmed as the world’s warmest March on record, it has never been clearer that we need to act with every lever we have to turn things around. At Zero Hour, we’re ramping up activities as we veer ever closer to the next UK Westminster General Election. We want to make sure that your next MP is ready to take environmental action as soon as they hit Westminster (more on this below!).

What is the Climate and Nature Bill?
The Climate and Nature Bill (CAN Bill) will make sure the UK does its bit to keep global warming down to 1.5°C, which gives us a chance to avoid the worst impacts of climate change. This means cutting down greenhouse gas emissions really fast. It’s a plan for a new UK law that addresses the full extent of the climate and nature crisis in line with the most up-to-date science. The Bill is the only proposed legislation before the UK Parliament that ensures a comprehensive and joined-up approach to the climate emergency and nature crisis.
While the existing Environment Act only offers to halt the decline of nature by 2030, the Climate and Nature Bill commits to reversing biodiversity loss by 2030. Weaning ourselves off fossil fuels means big changes. So it’s important that everyone is on board with them. That’s why the Bill also calls for a climate and nature assembly to help Government and Parliament develop an emergency strategy on the way forward.
The Bill, which was written by scientists, experts and campaigners, was first introduced in Parliament by Caroline Lucas MP in September 2020 and now has the backing of over 150 parliamentarians representing all major political parties.
Allow us to (re)introduce ourselves
As we gear up for the General Election, Zero Hour (the campaign for the Climate and Nature Bill) are making sure that the Bill is back on the books in parliament! This means we can sign up as many election candidates as soon as possible over the coming months.
We are proud that Labour/Co-op MP Alex Sobel is now leading the charge and reintroduced the Climate and Ecology Bill in the House of Commons in March—with cross-party backing from all major UK political parties—under a new name: the Climate and Nature Bill (or “CAN Bill”). The content of the CAN Bill is the same as the Climate & Ecology Bill—so that we are still holding the UK’s environmental ambition in line with science.

The Labour Party currently backs the “ambition and objectives” of the CAN Bill and with Alex Sobel taking the reins, we hope that we can get even closer to securing the party’s full backing. In 2019, Sobel set up the Net Zero All-Party Parliamentary Group to help secure a low carbon and clean industrial and economic future for the UK, and between 2021 and 2023 he was Shadow Minister for Nature Recovery and the Domestic Environment in the Opposition Party’s DEFRA team—so he is very well placed to help move the campaign forward.
Alex Sobel MP said:
‘I’m proud to have introduced the Climate and Nature Bill with cross-party support from MPs of all main parties. This joined-up climate and nature plan is continuing the legacy of the Climate Change Act 2008. This CAN Bill is needed if we want to reclaim our environmental leadership; and finally get serious about reducing energy bills, protecting our wildlife, creating green jobs, and bolstering our energy and food security.’
‘When made law, the CAN Bill will set the UK on a path where we can properly tackle the interconnected climate and nature crises—whilst making sure that no one is left behind in the long-overdue just transition we need. Global emissions are rising. Nature is in peril. So in this pivotal election year, let’s align our climate and nature laws in line with the science—and our international agreements—and deliver the climate and environmental action the public are crying out for.’
Chris Packham, Deborah Meaden and Tori Tsui launch ZH’s election campaign
This is the last Westminster general election, which will usher in the last Government able to turn the tide on climate change and nature loss—another five years will be just too late. This is why we’ve launched The Nation Needs You! Zero Hour’s election campaign calling on all candidates who will stand in the next General Election to back the Climate and Nature Bill. The launch (12 March) was packed and we were grateful to Chris Packham, entrepreneur Deborah Meaden, climate justice activist Tori Tsui, vice chair of Peers for the Planet Baroness Rosie Boycott and Zoological Society London scientist Prof. Nathalie Pettorelli for joining us.

Within twenty four hours of the campaign’s official launch, over 800 candidates (10% of the total number standing for election) had agreed to back the Bill. CE Bill supporters include both incumbent MPs and Westminster challengers from all main parties across the UK, including Conservatives, Labour, Labour/Co-op, SNP, Greens, Lib Dems, DUP, Plaid Cymru, Scottish Greens, SDLP and Alliance.
Tori Tsui said: “It’s not a surprise that this upcoming election is absolutely vital for ensuring rapid climate and nature action. We absolutely need candidates to stand by a commitment to the CAN Bill. As voters, we have a responsibility and duty to hold our candidates to account. We can’t delay action any longer. It is up to us to make our voices heard.”
