2020 marks the 50th anniversary of the Nelson Institute and the 50th anniversary of Earth Day — both testaments to Wisconsin’s environmental leadership and legacy. In celebration of these monumental occasions, we have dubbed 2020 the Year of the Environment (pdf) and invite you to celebrate with us.

Paul Robbins, dean of the Nelson Institute, invites you to join our 50th anniversary celebration.

Earth Day 50th Anniversary Conference

More than just a celebration of a global civic-focused day of action, Earth Day holds special significance for us here at the University of Wisconsin-Madison. We are deeply invested in the Earth Day legacy, the responsibility that it bears, and the call to action that it continues to present.
