Green Alliance is the UK’s leading environmental think tank, working to secure political leadership and action to address the climate and nature crises. Our vision is for a UK where people and the environment thrive together.
Founded in 1979 “to ensure that the political priorities of the United Kingdom are determined within an ecological perspective”, throughout our history we have been at the forefront of shaping the UK environmental agenda.
Our mission is to drive the ambitious, meaningful and urgent change in UK environmental policy and politics that enables people to thrive. We achieve impact by focused advocacy based on evidence and political insight, informed by an understanding of public opinion. We build relationships with a wide range of influential people and organisations and act as a bridge between them and political stakeholders to catalyse positive change. We are an independent, trusted, expert and non-partisan voice, working across the political spectrum.
We are known for our research and insightful analysis, providing evidence based solutions, improving understanding of complex environmental challenges and showing practically how to overcome them. Our advocacy is based on expert insights, aiming to drive greater political ambition, shape the political agenda on the environment and improve outcomes. We have established excellent relationships with politicians across parties, businesses and NGOs, and our work also involves significant engagement with civil servants, academics and the media. We regularly provide a platform for political leaders.
At the heart of what we do is forging constructive, purposeful alliances across sectors, to amplify messages, raise political ambition and secure progress. We convene through formal coalitions, informal networks and high profile events.
Some Of Our Recent Successes Include
February 2026, our freedom of information request led to the immediate publication of a suppressed a government a government assessment of the national security risks of global biodiversity loss and ecosystem collapse, which has gained global media coverage.
February 2026, Senedd Cymru passed an ambitious bill aiming to strengthen environmental laws and create an environmental watchdog, following sustained advocacy and advice from Green Alliance.
November 2025, the government published its first Methane Action Plan, strongly influenced by our work.
June 2025, our work was cited by ministers and MPs as vital in securing the UK ban on disposable vapes for the benefit of health and the environment.
November 2024, we were pivotal in gaining government commitment to create a new Circular Economy Strategy for England.
Our Strategy 2025-30
Our strategy 2025-30 focuses on strengthening the political mandate, at a time when the consensus around climate action in particular is at risk. While we understand political and policy realities, we never lose sight of the need for higher ambition. A non-partisan, cross party approach is at the heart of our work. The combination of our research, policy and analytical expertise gives us the credibility to lead political engagement. Work in alliance with a wide range of senior voices across sectors helps us to amplify impact. We expect the period to 2030 to be volatile and aim to increase our agility to react rapidly and change course when needed. Internally, we are focused on faster decision making, leaner organisational infrastructure, more effective communication and continuous impact monitoring. Throughout our work we propose fair, people-focused solutions that will make action on climate and nature politically possible.

Green Alliance’s Core Values
We are optimists: Grounded in evidence, we are ambitious about the change we can secure and persistent in pursuing it. We believe our vision of a UK where people and the environment thrive together is achievable.
We are collaborative: We are deeply invested in a strong and broad ecosystem calling for progress. We collaborate across sectors to design and implement winning strategies.
We are impact focused: We secure impact by focusing on real world outcomes. We are responsive, flexible and adapt our approaches towards the most impactful ways of securing change.
We embrace complexity: Environmental issues are inherently complex and inseparable from other important issues, including social impacts. We address this complexity head on, bringing clarity and direction through our work.
We are inclusive: We will strive to increase our own diversity and will ally with, support and learn from diverse voices and communities. An inclusive approach is essential to our success.
Our Commitment to Equity, Diversity and Inclusion
To achieve our mission, we aim to develop policy solutions that create a better future. As well as the environment, we consider people and social justice when designing environmental policies to bring about a fair green economic transition.
We believe making progress on equity, diversity and inclusion (EDI), including our commitment to anti-racism, is essential to our success and we recognise that this is a continuous process of improvement and learning.
The environmental and think tank sectors are among the least diverse workplaces in the UK. We are committed to changing that, in both the way we operate and by exercising our influence.
Our new Executive Director needs to be fully committed to EDI with experience of leading and developing the culture of an organisation.
At Green Alliance we believe that a diverse team leads to higher quality policy development and advocacy for the environment. We value the breadth of lived experience of our staff and support people to thrive. We encourage applications from all sections of society, particularly those from working-class backgrounds and people of colour who are under-represented in the environment and think tank sectors, to help us achieve our vision of a UK where people and the environment thrive together.
