A Moment of Choice
On 23 June 2026, in a special address at London Climate Action Week, the UN Secretary-General draws on the latest scientific evidence to show how the worsening climate crisis and growing energy insecurity are rooted in continued fossil fuels dependence. He outlines a clear pathway to accelerate the transition to a more secure, resilient and sustainable energy future: one powered by renewable energy, strengthened international cooperation, and science-based action.
The Secretary-General highlights how renewable energy offers the clearest route to energy security, affordability and resilience, while underscoring the urgent need to strengthen adaptation efforts in a world already experiencing dangerous climate impacts. He also makes an urgent call to action to cut methane emissions — one of the fastest and most powerful drivers of global warming.
The Case for Urgent Action on Methane
The UN Secretary-General's Call to Action on Methane offers a practical roadmap for governments, industry and financial institutions to rapidly cut methane emissions this decade through proven and cost-effective solutions. Developed by the UN Secretary-General’s Climate Action Team in collaboration with UN partners and leading institutions, the Call to Action highlights how methane reductions can deliver immediate climate benefits alongside cleaner air, stronger food systems and economic opportunity.
