Protest and the Ballot Box

Why this matters

Disruptive protest is one of the most contested tactics in the climate movement. Critics argue it alienates voters and benefits anti-climate parties. Supporters argue it shifts attention and pressure onto decision-makers. Until now, the question of whether protest actually moves electoral preferences - the metric politicians watch most closely - has been underexamined.

What we found

In Germany, Last Generation protests were associated with rising support for the pro-climate Linke and falling support for the anti-climate AfD. In Sweden, Restore Wetlands protests boosted the Centerpartiet by 0.45 percentage points, with parties tending to benefit more the more pro-climate their stance. In the UK, Just Stop Oil protests raised Green Party support by 0.34 points but also trended towards a rise in Reform UK support, suggesting a more polarising dynamic. Nevertheless, across all three countries, we found little evidence of backfire effects against pro-climate parties.

What it means for the movement

Disruptive climate protests can shift voting intentions in a pro-climate direction, with effects comparable to or slightly exceeding those of political advertising and in-person campaigning. Even modest shifts matter: policymakers track polls closely, and changes in voting intention can shape policy decisions between elections. The UK pattern suggests media and political context may shape whether protests unify or polarise - worth attending to for organisers planning future tactics.
