Earth Day 2026 -- April 22

This is our city. This is our air. This is our water.

Earth Day is not a hashtag. It is a Wednesday. And these Houston organizations will be doing the work that day — same as every other day. Here is how to join them.

April 22, 2026

Earth Day is Wednesday.
What are you doing?

Houston sits on the Gulf Coast, in a floodplain, downwind from the largest petrochemical complex in the Western Hemisphere. Our air quality ranks among the worst in America. Our bayous flood every year. And our neighbors are organizing every single day to change that. Earth Day is not the start — it is a checkpoint. Show up Wednesday. Then show up again.
