Tri-City Ecology Center (TCEC) | Conservation, Preservation, Education

The natural environment of Fremont, Union City and Newark — like the rest of the Bay Area — is under intense developmental pressure. Rapid growth imperils habitats, from the hills to the Bay itself.

Founded in 1971, the Tri-City Ecology center (TCEC) is your local leader in advocating sound environmental policies that preserve and maintain unique natural resources, clean air, clean water, and a high quality of life.

Please join us in protecting our environment!

Join the Tri-City Ecology Center Climate Challenge and take climate action from home!

Did you know that 40% of US emissions come from 5 basic household activities (transportation, home heating fuels, electricity, food, and waste)? And now there are affordable solutions for each of these activities that can greatly reduce our carbon footprint, and even save us thousands of dollars!

Join the TCEC Climate Challenge today! It’s easy – all you have to do is:

1. Complete your “energy profile” to learn about your household’s carbon footprint.
2. Browse the 90 climate-friendly and sustainable actions and select a few to start seeing big cost and resource savings!
3. Celebrate that you’ve helped to protect our air, water, and our future.

Why wait: Join today to start fighting climate change in your own home. We are working to have 100 households join and take 3 actions each by Earth Day to reduce CO₂ by over 100 tons!

Remembering Donna Olsen (1931-2020)

It is with sadness and regret that we mourn the loss of Donna Olsen, an original organizer of the Tri-City Ecology Center in 1971. Donna served on the initial Board of Directors and continued to serve until her recent passing. She filled every position at some time, but her prime role for decades was to be the editor of Eco-Logic, TCEC’s monthly newsletter. She was respected as a community activist, an environmental leader, an opinion shaper and a model for others to emulate. She was a true gem of Fremont, and a part of its long history, and she will be sorely missed. Read more about Donna’s many contributions to TCEC and our community.
