Whether mapping climate pollution from space or cutting air pollution on the ground, science drives all we do. It takes rigorous science to protect people and the planet. Our groundbreaking studies put the powerful climate pollutant methane on the international agenda — and we’re the only environmental organization building a satellite to map, measure and reduce it. Our work Our scientists lead large-scale collaborations with university and industry partners to guide our work. We even worked with Google to map air pollution at a level of detail never before achieved. We also fight to protect public health and to stop government attacks on science.
