Legislators are crucial to delivering climate and nature goals - turning domestic and international commitments into real-world action.
Peers for the Planet is a cross-party group of over 170 members of the House of Lords (Peers), working to put climate and nature at the top of the political agenda and to demonstrate UK leadership on a fair transition.
Our approach is non-partisan and collaborative, and our work focusses on both immediate priorities and long-term, systemic change.
We help Peers scrutinise, debate and amend legislation by ensuring they have access to high-quality scientific evidence and expert insight, so that they can assess each Bill’s implications for climate, nature and fairness - and how it could be strengthened. This applies across a wide range of policy areas, not just environmental legislation.
We do this by providing analysis and tailored, bill-by-bill support in the Lords, along with specialist briefings, roundtables, and practical help to contribute to debates, questions and amendments.
We connect Peers with leading expert organisations and we advise partners across civil society, academia and industry on how to engage effectively with parliamentary processes – strengthening their efforts as well.
Since the group was established in 2020, climate and nature issues have gained far greater prominence in the Lords. Our supporters have secured stronger climate provisions in legislation and more ambitious policies across government departments.
Why the Lords?
Legislators are crucial players in a just transition: the policy and legislative frameworks designed now will determine whether the UK can tackle the scale of the environmental and social challenges we face, now and for future generations.
While action by Government and in the House of Commons is essential, the House of Lords plays a distinct role as the UK’s second chamber. It is the only place where Bills are scrutinised line-by-line, enabling Peers to test the detail, propose changes and press for practical improvements.
The Lords also brings long-term thinking, drawing on members’ expertise across a wide range of disciplines and backgrounds and it has a culture of collaboration and a track record of securing world-leading reforms in the public interest.
Peers can also initiate legislation through Private Members’ Bills – helping put new solutions on the agenda and build momentum for change.
Since Peers for the Planet was established, every major reform that links key sectors or institutions to the UK’s climate and nature goals has been won in or instigated by the Lords.
The Parliamentary Group

Peers for the Planet supports members of the House of Lords from all parties and none. We work with experienced environmentalists and Peers who bring rich and valuable knowledge from other policy areas.
This broad reach builds cross-party momentum and holds space for consensus-building – helping to inform the political agenda and win ambitious, practical changes in law and policy, regardless of which party is in government.
