Children's Environmental Health Day

Each year on the second Thursday of October, the children’s environmental health community commemorates Children’s Environmental Health Day (CEH Day). This day anchors the overall Children’s Environmental Health Movement and is a rallying point for education, and for individuals and organizations to take action on behalf of children’s environmental health.

If you advocate for a healthier environment for our nation's children, we invite you to join us!

Organizations, communities, and families can organize their own CEH Day activities or join existing ones. Get inspiration for creating your own event for 2021!


CEH Day 2021 is on October 14!

Days Until Children's Environmental Health Day 2021:

The fifth annual
Children's Environmental Health Day

October 8, 2020 was the fifth annual Children's Environmental Health Day. In addition to the 12 proclamations issued by cities, states, and counties across the US and 40 CEH Day activities held by child health advocates, organizers, and leaders nation-wide by our 55 partner organizations, CEHN hosted our first-ever CEH Day Livestream.

Individuals and organizations contributed 70 different "scenes" that made up our 12 hour program, which had a reach of nearly 4,000 and over 25,800 minutes watched.

CEHN also hosted a Twitter chat on climate and children's health and was joined by  63 organizations and individuals who shared their unique insights and valuable resources on this urgent children's health issue.

The Day was bolstered by 55 CEH Day partners, generous sponsors, and  content creators who made #CEHday Live a fabulous reality. The purpose of CEH Day is to increase visibility of and bring real change around children's environmental health issues. We can estimate a small part of the increased visibility from the reach of the day's hashtags (#CEHchat, #CEHday, and #ChildrenAtTheCenter had an estimated reach of 2.7 million yesterday alone). However, we are far more excited to watch and take part in the true measure of success of CEH Day throughout the next year- creating true and lasting changes to our policy, our practices, and our knowledge that cultivate a safer, healthier future for our children.
