San Diego’s long game on climate just got a crucial federal nod. SANDAG’s San Diego Regional Climate Action Roadmap has cleared federal review, the regional planning agency announced Friday, setting up a decades-long strategy that runs through 2045 for cutting climate pollution across the county.
The sign-off caps months of outreach and technical work, and SANDAG says the final product reflects what residents shared at public meetings, in surveys and through written comments.
What SANDAG Announced
According to SANDAG, the federal government approved the Roadmap in January 2026. The agency publicly thanked residents who showed up at meetings, filled out surveys and submitted written comments.
SANDAG describes the Roadmap as a regional blueprint that pulls together local plans, technical analysis and community priorities into one document. With federal approval in hand, the agency says the region is poised to shift from high-level planning toward more coordinated work on identifying specific projects and lining up funding.
What Is In The Roadmap
The San Diego Regional Climate Action Roadmap, completed on December 1, 2025, lays out 23 long term greenhouse gas reduction measures across transportation, electricity, buildings, industry, waste, water and natural lands, according to the San Diego Regional Climate Action Roadmap. The plan details how the region could cut emissions 47% by 2035 and 83% by 2045.
The 115 page document notes that the work was funded with a planning grant from the U.S. Environmental Protection Agency. It also includes analyses of air quality co benefits, workforce needs and community priorities that are expected to intersect with the climate measures.
Why Federal Approval Matters
The federal sign off is a key box checked because the Roadmap was developed under the EPA’s Climate Pollution Reduction Grants program, a roughly 5 billion dollar federal effort that supports planning and competitive implementation awards for states, cities and tribes, according to the EPA.
Tapping into that program can make it easier for regions like San Diego to compete for implementation funding and technical assistance. Still, local agencies will have to win project level grants and pull together matching resources. The EPA initiative includes noncompetitive planning grants, along with competitive awards for implementation, which is where most construction and larger investments would be financed.
Next Steps For San Diego
SANDAG and its partners say the immediate work now centers on coordination. That includes aligning the Roadmap with existing city and county climate plans, prioritizing near term projects and chasing state, federal and philanthropic dollars, as outlined in the Roadmap’s “Next Steps” section.
The agency plans to track outcomes, update measures as new data rolls in and focus on making sure investments deliver clean air, climate and equity benefits to frontline neighborhoods. Implementation will be phased. Some actions can start relatively quickly, while others will depend on new technology, policy changes or significant capital.
Officials emphasize that the Roadmap does not legally bind local governments. Instead, it is meant to function as a shared framework for collaboration across jurisdictions. SANDAG says it will keep the public in the loop as ideas move from concept to funding and eventually construction.
Residents are told to expect board briefings and public workshops as the agency works through its implementation pathways in the coming months.
