The first Earth Day over 50 years ago ignited a movement to stop polluting our planet. Today, our scientists and experts are tackling the most pressing challenges to achieve real-world impact: food security, decarbonization, healthy water systems, climate resilient cities, disaster preparedness, and more. This Earth Day, with a special focus on reducing plastics, join us in our commitment to realizing a just and sustainable future for our planet.
