What is the Environmental Sustainability Master Plan?
Thornton is committed to addressing City-wide sustainability and ensuring a resilient future for our community. Our 2026 Environmental Sustainability Master Plan (ESMP) builds on our previous sustainability efforts, including the 2020 Thornton Comprehensive Plan, the Sustainability Action Agenda, Transportation and Mobility Master Plan, the Water Efficiency Plan and more. It establishes a clear, equitable, and actionable roadmap to reduce greenhouse gas emissions, strengthen our community’s resilience, and protect our natural environment.
This initiative is driven by science, data, and community input. It prioritizes inclusivity, as all residents—especially those from historically underrepresented communities—have a voice in shaping our sustainable future.
