Why the May Elections Matter for the Sustainability Movement

A growing body of evidence points to a troubling disconnect: public support for climate action remains relatively strong, yet the story we hear about it is increasingly negative.

Recent survey data suggests that right-leaning media narratives are amplifying a false backlash against net zero. Coverage is now more than twice as likely to skew negative than public opinion would justify. The result? A distorted picture in which climate policies appear far less popular than they really are.

This misperception has real consequences. Decision-makers and businesses begin to second-guess public appetite for change. Investment slows. Ambition softens. Confidence drains away.

That is why the May elections matter.

If parties like Reform perform strongly, it risks reinforcing the idea that voters are turning decisively against climate action regardless of whether that’s actually true. Narratives harden quickly in politics, and once embedded, they shape not just debate, but decisions: what gets funded, what gets prioritised, and what gets quietly dropped.

A Public Mood Set Against Change

To understand what may happen next, we need to look at the wider context.

Analysis from IPSOS paints a stark picture. Economic optimism is at its lowest level in nearly half a century of tracking. Confidence in public services has collapsed, with eight in ten people believing they are getting worse. Global instability - particularly conflict in the Middle East - is likely to push energy prices higher and further strain household finances.

This is fertile ground for political disruption.

When people feel economically insecure and pessimistic about the future, they become more open to risk. Unsurprisingly, six in ten voters now say that radical change is worth it. At the same time, while support for democracy itself remains solid, dissatisfaction with how the system is working is widespread and deep.

A Fragmenting Political Landscape

This mood is reshaping the political map.

Support is splintering. Voters are drifting away from traditional party loyalties, creating space for smaller and insurgent parties to grow. Reform and the Greens are both well placed to capitalise on disillusionment drawing support from opposite ends of the political spectrum but tapping into a similar sense of frustration. The Liberal Democrats may attract those seeking a more stable, centrist alternative, while nationalist parties could consolidate their positions in Scotland and Wales.

The result is a far more volatile and unpredictable electoral landscape.

What This Means for Sustainability

Several implications stand out and all of them matter for the future of climate action.

1. The two-party system is under real strain

With five parties now polling at broadly comparable levels, the UK’s electoral system is starting to look increasingly misaligned with political reality. Outcomes may become more distorted, not less creating governments with large majorities but limited mandates for bold, long-term change.

2. A new generation of political leadership may emerge

Electoral turnover could bring in representatives with less experience but more openness to new ideas. That creates uncertainty but also an opportunity to shape fresh approaches to sustainability.

3. Collaboration will become unavoidable

Fragmentation makes cross-party working essential rather than optional. For the sustainability movement, this is both a challenge and an opening: progress will depend on building broader, more flexible coalitions.

4. Narrative will be emotive

In a crowded political environment, the simplest and most emotionally resonant stories win. Parties like Reform and the Greens are already demonstrating this. By contrast, more complex or technocratic messaging on net zero risks being drowned out no matter how evidence-based it is.

5. Incumbency is a growing liability

Where the public mood is one of decline, those in power struggle to convince voters that progress is being made. This creates headwinds for any government trying to advance long-term sustainability policies that require patience and trust.

The Bottom Line

The May elections are not just another political milestone. They are a test of the narrative around climate action itself.

If the results are read as a rejection of net zero, the ripple effects will be felt far beyond politics shaping investment decisions, corporate behaviour, and the confidence of institutions to act.

But that outcome is not inevitable. The gap between perception and reality is still there and closing it may be one of the most important tasks for those working to advance sustainability
