Green Alliance is a charity and independent think tank based in central London, United Kingdom (UK). It researches and recommends new environmental policy proposals, and works strategically, in alliance with other non-governmental organisations (NGOs) and businesses, on promoting greater political support for the environment. The organisation conducts analysis on a range of policy themes: ‘natural environment’, ‘low carbon future’, ‘greening the economy’ and ‘resources’. Its ‘political leadership’ theme focuses on raising the ambition and commitment of politicians to act on climate and nature, highlighting the social and economic advantages of doing so. Many of Green Alliance's projects involve collaboration with partners, in businesses, academia and other NGOs. For instance, it has run a Circular Economy Task Force of businesses to advocate better resource management since 2013, and it leads the Greener UK NGO coalition, which has worked on UK post-Brexit environmental governance since 2016. Green Alliance hosts a blog and a podcast giving voice to organisations, opinion formers, experts and commentators on environmental issues. It holds regular events, including hosting major speeches by senior ministers and political leaders, such as Tony Blair, Caroline Lucas, David Cameron, Al Gore, Nicola Sturgeon, Alok Sharma and Kwasi Kwarteng. People Notable individuals involved in Green Alliance's early years include Maurice Ash, Tim Beaumont, Tom Burke, Julie Hill and Rebecca Willis. Shaun Spiers has been executive director since 2017. Since the early 1990s, Green Alliance has regularly convened a strategic alliance of the chief executives of UK's foremost environmental NGOs, leading joint advocacy on major national policy issues.

One of the founders, Maurice Ash, said at the launch "We’re a bunch of optimists. We’re not the doomsters. We believe in the possibilities of the future...” The initial ‘alliance’ was a cross party, cross sectoral group of senior figures, including peers, judges, organisational leaders and academics. Green Alliance has since focused on influencing the ambitions of UK government environment policy using a collaborative approach. In the 1980s, it elicited the first ever environmental policy statements from all the main UK political parties. It was the first organisation in the UK to raise genetic modification (GM) as an environmental issue at the end of the 80s, with a
