Propelled by the philosophy that “what gets measured, gets managed,” SSMC began tracking sustainability metrics for local cities and our county in 1997. We have been celebrating sustainability champions since 1999. The growing impacts of climate change and widening inequality in income and opportunity have prompted us to become more proactive in advocating for sustainable programs and policies. In 2019 we started the Sustainability Ideas Bank to equip local cities with proven sustainability solutions. In addition, we partner with other organizations to encourage sustainability programs and policies.

Indicators Report

Our Indicators for a Sustainable San Mateo County reports provide fact-based information on local trends impacting our economy, environment and society. This annual report presents metrics that raise awareness of sustainability in the county and improve our ability to make sound decisions for the benefit of future generations.



SSMC Awards

Each year SSMC celebrates sustainability champions with prestigious awards. In addition to our Sustainability Awards, we collaborate with the San Mateo Chapter of the American Institute of Architects to present Green Building Awards to sustainability building owners, architects and builders. In 2020 we presented Reach Code Awards for the first time. The SSMC Board also recognizes exemplary contributors to our work with the Ruth Peterson Award, named in honor of SSMC’s founder.


Sustainability Ideas Bank

The Sustainability Ideas Bank offers proven, impactful sustainability solutions to local cities and businesses that have been implemented successfully elsewhere. Why reinvent the wheel when you can benefit from the experience of others? Each solution includes resources and contact information so people can get questions answered by those who have paved the way.



To help accelerate sustainability, SSMC advocates for programs and policies that align with our values, and we partner with other organizations to magnify our mutual efforts. Recent efforts have included advocacy for equity in local mass transit with the Transportation Equity Allied Movement Coalition (TEAMC) and supporting electrification of buildings and electric vehicle infrastructure with the Campaign for Fossil Free Buildings in Silicon Valley. In 2020 we affirmed our support for working with communities of color and helping to eliminate racism with a Racial Equality Proclamation.
