Climate action creates jobs, drives innovation, and builds stronger communities. It protects lives, fuels economies, and shapes a more abundant future for everyone. If you know a leader, an innovator, an educator — someone who steps up when others look away — nominate them for the UN Environment Programme’s Champions of the Earth 2025 award, the UN’s highest environmental honour. It recognizes outstanding leaders from government, civil society and the private sector whose actions have a transformative impact on the environment.
