More than 1 billion people now participate in Earth Day activities each year, making it the largest civic observance in the world.

Get the scoop on Earth Day Network’s big plans for 2020, the 50th anniversary of Earth Day: citizen science, clean-ups and tree-planting, huge events, and more.

2020 theme: Climate Action

The enormous challenges – but also the vast opportunities – of acting on climate change have distinguished the issue as the most pressing topic for the 50th anniversary year. At the end of 2020, nations will be expected to increase their national commitments to the 2015 Paris Agreement on climate change, so the time is now for citizens to call for greater global ambition to tackle our climate crisis.
