Best Green Infrastructure Grants in California

The Community Planning and Capacity Building Grants, offered by the California Air Resources Board, provide up to $500,000 to assist communities in planning for equitable transportation solutions. These grants focus on early-stage planning, outreach, and workforce development, particularly benefiting Tribal governments, rural communities, schools, and first-time applicants. This funding aims to promote clean transportation initiatives and enhance local readiness.

The Climate Adaptation Planning Grant, part of California's Sustainable Transportation Planning Grants, provides $3 million to support local and regional efforts in addressing climate vulnerabilities in transportation infrastructure. This grant encourages the development of adaptation plans that aim to mitigate damage from climate change and extreme weather. Open to applicants with ongoing or new adaptation efforts, it fosters strategic planning for roads, railways, and other critical transport systems across the state.

The Tribal Solar Accelerator Fund (TSAF) empowers tribal communities across the U.S. by promoting renewable energy projects and workforce development. Launched by GRID Alternatives, TSAF provides critical funding for solar initiatives, enhancing energy sovereignty and resilience. Since its inception, TSAF has integrated community participation into its projects, ensuring that tribes can access sustainable energy solutions. By prioritizing education and equity, TSAF supports a transition to a clean energy economy, aiming for a sustainable future for generations to come.

Urban Greening 2026

Urban Greening Grant Program funds projects that use nature-based solutions to mitigate the urban heat island effect, rising temperatures, and extreme heat impacts in urban areas.

The 2026 Urban Greening Grant Program will solicit Step 1 Concept Proposals (between May 4-June 4) and extend invitations to submit Step 2 Full Proposals in July 2026.

Successful projects will green and cool communities and offer multiple benefits including sequestering carbon, limiting stormwater runoff, providing habitat and preserving biodiversity, protecting public health during extreme heat, increasing equity, and expanding economic and workforce opportunities. Funded projects are expected to advance the goals of the State’s Extreme Heat Action Plan and Nature-Based Solutions Climate Targets.

Urban Greening projects must comply with all the following:

• Be located in an urban area;
• Provide public benefit; and
• Provide public access

The GFO-23-318 – BRIDGE 2024 initiative aims to accelerate clean energy innovation in California by funding Applied Research and Development (AR&D) and Technology Demonstration and Deployment (TD&D) projects. With over $25 million available, this program supports promising technologies that have received prior funding from the California Energy Commission or eligible federal agencies. It focuses on enhancing entrepreneurship by providing non-dilutive investments to early-stage clean energy companies, fostering market adoption of efficient energy solutions.

The Environment Pillar Award by Honda supports nonprofit organizations and schools in the U.S. focused on sustainability. Grants aim to reduce environmental impact through programs in decarbonization, clean energy, and efficient resource use. Eligible projects must align with Honda's mission and primarily benefit communities where Honda associates live and work. Organizations can apply for up to two grants, provided they meet specific eligibility criteria, including tax-exempt status under the IRS.

California Natural Resources Agency

The California Natural Resources Agency oversees and supports more than 26 distinct departments, conservancies, and commissions. Our Agency Executive Team leads efforts to steward California’s natural environment and to advance Governor Newsom’s key priorities.

Over 25,000 Californians work within our Agency all across the state to meet our mission to protect, manage, and restore the state’s environment and its vast natural, cultural, and historical resources. We advance this work with science as our foundation and inclusion and collaboration as our guiding principles.

Urban Greening Grant Program

Funding Purpose

The Urban Greening Grant Program will fund projects that use nature-based solutions to mitigate the urban heat island effect, rising temperatures, and extreme heat impacts in urban areas.

Nature-based solutions include all the ways land can be managed to boost the health and resilience of natural systems, helping them store carbon and protect against climate change impacts, including extreme heat. Nature-based solutions that address extreme heat impacts use natural cooling strategies to limit temperature increase and urban heat islands. Examples include planting trees that provide strategic shade, expanding green spaces that serve as places of refuge during heat waves, and increasing tree canopy cover in cities, communities, and schoolyards.

Successful projects will green and cool communities and offer multiple benefits including sequestering carbon, limiting stormwater runoff, providing habitat and preserving biodiversity, protecting public health during extreme heat, increasing equity, and expanding economic and workforce opportunities. Funded projects are expected to advance the goals of the State’s Extreme Heat Action Plan and Nature-Based Solutions Climate Targets. 

GFO-25-607 - Clean Transportation Program Hydrogen Infrastructure Project Opportunity (HIPO)

The purpose of this solicitation is to fund the deployment of hydrogen refueling infrastructure for light-, medium-, and/or heavy-duty on-road fuel cell electric vehicles.

This is a competitive grant solicitation. The California Energy Commission’s (CEC’s) Clean Transportation Program announces the availability of up to $45 million in grant funds for projects that will fund the deployment of hydrogen refueling infrastructure for light-, medium-, and/or heavy-duty on-road fuel cell electric vehicles (FCEVs). 

Of the $45 million, up to $21.2 million is dedicated to light-duty hydrogen refueling infrastructure and up to $23.8 million is dedicated to light-, medium-, and/or heavy-duty hydrogen refueling infrastructure.  

The solicitation objectives are to:

• Deploy new hydrogen refueling infrastructure for light-duty (LD) vehicles, with an emphasis on stations located in Santa Monica/West Los Angeles, San Francisco, Sacramento, and San Diego to alleviate market stress due to station demand, as well as medium-duty (MD) vehicles, or for heavy-duty (HD) uses including drayage, transit, and port operations. New hydrogen refueling infrastructure can also be a combination of the infrastructure types (mixed-use) listed above.
• Reopen temporarily non-operational (TNO) stations that would otherwise not return to open retail status.
• Provide additional funding for stations awarded under CEC Grant Funding Opportunity (GFO)-19-602 which are fully permitted and lacking capital to finish construction.
• Provide operations and maintenance (O&M) funding for the projects listed above once the station becomes open retail.

The Electric Vehicle Infrastructure Training Program (EVITP) Fund Grant, offered by the California Employment Training Panel, provides up to $2.7 million to train and certify electricians in installing electric vehicle charging equipment across California. This initiative aims to enhance the workforce's skills in a growing sector, ensuring economic competitiveness and job security within the state. The program represents a collaborative effort to support sustainable energy infrastructure and job creation in California.
