Global Solidarity Report 2025:
How to get net-zero back on track

The Global Solidarity Report 2025 confronts the world’s biggest test – a net-zero transition and argues that the climate crisis is fundamentally a solidarity crisis. Despite clear technical pathways to phase down fossil fuels and accelerate the transition to clean energy, global solidarity has collapsed to perilous lows and puts this task in jeopardy.

This year the numbers are alarming. Global solidarity has been in decline for more than a decade and has now reached 33 out of a possible 100. And it is the first time the report’s public polling by Ipsos shows a drop in agreement with every solidarity question across generations, genders, income groups, and in wealthier and poorer countries.

Today, the incentive to prioritise narrow national or political interests over humanity’s shared future are far too strong. So what do those of us who want to solve global problems like net zero do in a low solidarity world? The report explains history teaches us how we need groups of people taking action to create powerful ripple effects that make more and more people believe change is possible. Eventually solidarity is built and becomes strong enough to unlock transformational change. It provides two ‘big bets’ for 2025 that it argues are the kind of action that can move the needle on both climate progress and solidarity at large.

The Global Solidarity Report 2025 arrives at a critical moment, rightly stating that the climate crisis is a solidarity crisis.Yet it also shows that in world where solidarity is weak, concrete actions can reverse this trajectory, including new alliances of responsible governments, and communities of citizens and businesses leading by example through collective commitment.

The Global Solidarity Report reminds us that cooperation and inclusion are the true sources of resilience. When we invest in knowledge, transparency, and participation, we strengthen not only our energy systems but also our democracies and trust in our institutions.

The Global Solidarity Report affirms that when solidarity is weakening, driving action with those who are prepared to step up can halt division and allow us to rediscover what humanity is capable of.

The Global Solidarity Report reaffirms a message I sent strongly at the UN General Assembly this year; failure is not inevitable, it is a choice. We have the scientific and technological solutions to avert a climate crisis, but we have not yet delivered the scale and pace of action we urgently need.

The Global Solidarity Report warns that a lack of solidarity is holding back climate progress and rightly offers hope that ‘coalitions of the willing’ can move the needle in these challenging times.
