The UN Environment Programme has named five new climate visionaries as its 2025 Champions of the Earth, recognizing their work on climate justice, sustainable cooling, forest protection, and methane emissions reductions. The laureates, including Pacific Islands Students Fighting Climate Change, Supriya Sahu from Tamil Nadu, Mariam Issoufou Architects, and Imazon from Brazil, are driving real change for people and the planet with their innovative leadership in areas such as climate law, sustainable cooling, resilient buildings, and deforestation prediction models. Imazon's non-profit research institute, using science and AI-driven geospatial tools, is curbing deforestation in the Amazon and supporting legal cases. Cynthia Houniuhi is honored for pioneering forest monitoring systems, while Manfredi Caltagirone, posthumously awarded the Lifetime Achievement Award, dedicated his career to addressing climate challenges, particularly methane emissions, and shaping global energy policy through his work at UNEP's International Methane Emissions Observatory.
