UN climate conference in Belém, Brazil

COP30 concluded with an agreement on a wide range of climate issues among all 193 countries present at the conference, showing that nations can still come together to confront the defining challenges no country can solve alone. "COP30 has delivered progress," UN Secretary-General António Guterres said. But he urged countries to go further, through deep and rapid emission cuts and credible plans to transition away from fossil fuels and toward clean energy.

Events

World Cities Day

This year’s World Cities Day showcases how data-driven decision-making, technology, and AI can be used to improve urban life and recover from climate change impacts. From early warning systems to geospatial mapping, digital tools can improve basic services, strengthen urban resilience, and create greener spaces for all.

World Tsunami Awareness Day

Tsunamis threaten human life, disrupt livelihoods, industry, agriculture, gender equality, and critical services such as education and healthcare. Investments in tsunami early warning, evacuation mapping, and risk education are vital to enhance local preparedness and limit impacts. Learn more about early warning systems here.

World Sustainable Transport Day

The transport sector accounts for roughly 15 per cent of total greenhouse gas emissions, making it the fourth largest source of global emissions. Without action, transport-related emissions could grow by up to 65 per cent by 2050. Decarbonizing the transport sector, through measures like electromobility and alternative fuels, is vital to limit global warming. Learn more about transport and climate change here.
