Earth Challenge 2020

A Citizen Science Initiative

Earth Challenge 2020 will help fulfill our goal of engaging millions of global citizens.

What is Earth Challenge 2020?

April 22, 2020 marks the 50th anniversary of Earth Day. In recognition of this milestone Earth Day Network, the Woodrow Wilson International Center for Scholars, and the U.S. Department of State are launching Earth Challenge 2020 as the world’s largest coordinated citizen science campaign.

Earth Challenge 2020 will engage millions of global citizens to aggregate and collect more than one billion data points in areas including air quality, water quality, biodiversity, pollution, and human health. Through Earth Challenge 2020, citizen science volunteers will learn about their local conditions, and leverage information to inspire collaborative action and influence policy decisions.

Why citizen science?

Citizen science involves members of the public in scientific research to meet real world goals. Members of the public collect and share information at scales and resolutions previously unachievable.

How can I get involved?

There are many ways to join the movement.

The timeline for Earth Challenge 2020 spans eighteen months.

  • In 2018, we are asking people around the world to submit research questions to inform the direction of the project.
  • In 2019, hackathons will be hosted around the world to help create the technologies that will underpin Earth Challenge 2020 and encourage existing citizen science projects to join our efforts.
  • In Spring 2020, a new mobile app and global data collection campaign will launch with the objective of collecting one billion data points by Earth Day that year. Stay tuned!
