Special Address by the Secretary-General on the Global Response to the Climate and Energy Crises
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.
