Working toward a Sustainable Future
SANDAG is working to create a sustainable and safe future for everyone in the San Diego region. Although we enjoy one of the most temperate climates in the world, our region is still affected by a range of climate and environmental challenges. Hotter and more frequent heat waves, prolonged droughts, more destructive wildfires, degraded air quality, more extreme precipitation and flooding, rising sea levels, and destructive coastal storm surges are already impacting people, communities, and critical infrastructure. Given the increasing intensity and frequency of these events, the region will need to plan and invest differently to reduce risk and strengthen long-term resilience.
SANDAG is working with partners across the San Diego region to address both the causes and impacts of climate change. Our programs include climate mitigation, which focuses on reducing greenhouse gas emissions (GHGs), and climate adaptation, which focuses on reducing risks and preparing communities, infrastructure, and natural resources for climate-related impacts.
Current Key Projects
The California-Baja California Border Resiliency Plan (BRP) is a binational effort to study how climate hazards are impacting border region communities and ways for transportation infrastructure to better adapt to those conditions. The BRP will study conditions and identify strategies, programs, and projects that will help enhance and protect transportation infrastructure and the people who depend on it.
SANDAG collaborated with local governments, regional agencies, and other partners to complete the San Diego Regional Climate Action Roadmap in December 2025, which helps coordinate regional action to reduce GHGs. Together, these efforts help address shared regional climate challenges and support a more resilient San Diego region.
