European Green parties have experienced stagnation and crisis in recent years, a stark contrast to the 'green wave' of 2019 when they secured record results in European Parliament elections and entered governing coalitions across the continent. However, a 'greenlash' has seen them drop out of nearly all government coalitions, with election results often falling short of expectations. As enthusiasm for climate movements wanes, Green parties are seeking strategies to revive their fortunes.
The UK Greens’ Surge
For inspiration, Europe’s Greens should look to the UK, where the Green Party of England and Wales has soared in popularity under new leader Zack Polanski. With a historic byelection win in February, record results in May’s local and devolved elections, and membership tripling to over 230,000 in nine months, the party offers a compelling case study.
Shift in Messaging
Since Polanski’s election in September 2025, the party’s positioning has shifted notably. Climate breakdown and environmental protection are no longer dominant themes; instead, Polanski focuses on economic inequality, the cost of living, housing, and rent prices. He frequently speaks of 'the 99% versus the 1%,' taxing the rich, and 'rip-off Britain.' The Greens have also taken clear stances on the Gaza genocide and trans rights, distinguishing themselves from Labour.
Three Key Lessons for European Greens
1. Emphasise Economic Inequality
Research across 11 European countries suggests that Green parties can expand their electoral coalition by focusing on redistributive policies and economic inequality. This does not undermine their credibility on climate issues or demobilise core supporters. In the UK, a report on the May elections found that Green voters were equally motivated by redistribution and taxes as by climate breakdown. Among financially insecure voters with liberal social attitudes, 47% voted Green, far exceeding Labour’s 25%.
2. Hold Strong Positions on Key Issues
Clear support for trans and minority rights, as seen in the UK, not only boosts support among those who care about these issues but also allows the party to focus on other topics. By addressing 'gotcha' questions with unwavering clarity, the party can pivot to its core agenda.
3. Embrace Progressive Identity Politics
The UK Greens have become a home for progressive activism, welcoming those engaged in local organising, campaigning, and mobilising against war crimes. The party is present at protests, strikes, and cultural spaces, even organising raves. This approach mirrors successful campaigns like Zohran Mamdani’s in New York, building coalitions among progressive activists and marginalised groups.
A Unique Opportunity
While strategies must be tailored to national contexts, these three lessons are broadly applicable. The perceived 'greenlash' has made many Green parties hesitant, watering down demands and moderating appeals. The UK example suggests a different path: be bolder and clearer in messaging. With many social democratic parties weakening, Green parties have a unique opportunity to broaden their appeal and potentially become the dominant left-of-centre force in Europe.
