Sustainable San Mateo County (SSMC) is a nonprofit organization dedicated to advancing sustainability in San Mateo County (SMC) through data-driven education, policy insight and community engagement. Since its founding in 1992, SSMC has empowered local governments, businesses and residents with research and resources to accelerate the adoption of impactful sustainability policies.

Through our core programs, SSMC provides local leaders with reliable data, analysis and best practices, helping cities make informed decisions that address environmental, economic and social equity challenges. Beyond informing policy, SSMC builds public understanding of sustainability issues, equipping residents with the knowledge to advocate for change.

With a commitment to collaboration and practical action, SSMC continues to serve as a trusted partner in creating a resilient, thriving SMC.

Indicators Report

Our Indicators Reports deliver fact-based insights on local economic, environmental and societal trends. Each year, we select a deep-dive topic based on community priorities and map regional barriers and opportunities through data-driven research and interviews with local leaders, residents and CBOs. By co-creating solutions with those most affected, we ensure our findings are rooted in equity. Following publication, we host facilitated sessions with a cross-section of stakeholders—building a bridge between data and action to foster the cross-sector collaboration necessary to turn these insights into measurable regional progress for future generations.

The Sustainability Dashboard measures key performance indiactors accross the county

Sustainability Dashboard

Our Sustainability Dashboard tracks progress in 13 sustainability focus areas with over 90 equity-focused metrics for all 20 cities and the unincorporated areas of San Mateo County. Local leaders and residents can track progress toward sustainability goals and identify where more work is needed. While sharing the data with city leaders, we also suggest proven solutions from our Sustainability Ideas Bank that have been successfully implemented by other cities.

Sustainability Ideas Bank

The Sustainability Ideas Bank offers over 90 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.

Youth Development

SSMC is cultivating the next generation of sustainability leaders. Since 2019, our internship program has trained more than 88 students in research, leadership and sustainable practices, inspiring many to pivot their careers toward climate action. Additionally, our Youth Advisory Council empowers nearly 50 high school students each year to spearhead their own advocacy and climate projects. These young leaders don’t just participate; they actively influence SSMC’s organizational priorities through direct input to our Board of Directors, while gaining the policy and advocacy skills necessary to lead future sustainability efforts across San Mateo County’s cities and schools.

Webinars

SSMC’s webinars bring people together and build community. At these online gatherings, you’ll meet experts on a wide variety of sustainability topics and explore solutions to current issues. You can ask questions and suggest ideas. Past topics have included gas-powered leaf blower bans, advocacy training for how to influence local policy and how communities and schools can work together to drive sustainable food system change.

Advocacy

SSMC believes in the power of advocacy to drive positive change in our communities. We do this by fostering connections among residents, local organizations and decision-makers to advance sustainability solutions. We equip communities with data and tools to advocate for their needs, with a special emphasis on ensuring historically marginalized communities play a central role in shaping program and policy decisions.
