Welcome to TREA
TREA’s (Thames Region Ecological Association) main goal is to educate its members and community to protect the environment, stay informed and take personal action. We also have an entrepreneurial streak given that TREA encourages citizen participation and innovative projects from and for the community.
Making a positive impact in our community
Waste & Recycling
Learn how to reduce waste through individual habits and larger events
Active Transportation
Learn the best practices and practical strategies for active transportation
Reducing Fossil Fuels
Gain practical knowledge & network to reduce reliance on fossil fuels
TREA projects support our strategic goals of increasing waste diversion, active transportation and reducing fossil fuel usage. These projects, in collaboration with other community organizations, have provided opportunities for residents to engage in more sustainable activities. We encourage self-sufficiency given TREA’s strong interest in relocalization, climate change stability, and energy conservation – which are important topics to Londoners.
