Decarbonizing Industry and Heavy Transport in California
California is a national leader in climate policy with state mandates to achieve net zero emissions by 2045. Yet, California is the third largest industrial emitter in the nation, with the state’s refineries, trucks, airports, ports and other industries responsible for 80 million metric tons of CO2 in 2022 or 6% of total industrial emissions in the United States.
Meeting our collective global climate goals requires building more than 700 net-zero industrial projects and purchasing 7 million zero-emissions trucks by 2030. Most of these projects will occur in regional industrial hubs in places like California where the physical, social, regulatory, and economic infrastructure is in place to support rapid scale up.
That’s why RMI and the Mission Possible Partnership, in collaboration with the Bezos Earth Fund, are working to create a clean industrial hub in California to help advance heavy transportation and port decarbonization, low-emissions cement production, green hydrogen, and industrial electrification. Investments to transition and build new, clean facilities and vehicles will reduce pollution and help the state reach its climate policy targets while creating a green economy for California workers.
Why California
California can lead the clean energy transition through its strong environmental regulations and world-leading customer base for sustainable products. In fact, California has the largest state economy in the United States and contributes 14% to the United States’ GDP.
While the state might be known for tech, film, and recreation, its industrial sector is a large part of its economy. The Ports of Los Angeles and Long Beach alone support 3 million jobs nationally and manufacturing contributes an additional 11% to California’s GDP. California’s industrial sector also brings significant pollution. Together, industry and heavy transport sectors like trucking, shipping, and aviation, contribute nearly 30% of all emissions in the state.
To support a sustainable future, California is leading on policy to unlock investments in clean fuels and industrial decarbonization. California has a net-zero emissions target by 2045, supported by key legislation for zero emissions vehicles, a low-carbon fuel standard, cap-and-trade program, and a Buy Clean Act. Combined with federal, state, and local funding for new and retrofitted facilities, these policies are catalyzing a wave of project announcements statewide. Between 2022 and 2024, more than 22 commercial scale decarbonization projects were announced in California across five sectors, including trucking, aviation, and shipping.
To date, clean industrial projects in California have mobilized more than $14 billion in public and private funding. This includes:
Even with the tremendous progress stakeholders have made in California to advance decarbonization projects, significant work remains to transition the state’s industries to net-zero by 2045.
Clean Industrial Hubs/Clusters – A Regional Approach
Clean industrial hubs bring together key stakeholders, such as project developers, policy makers, financial institutions, and community-based organizations to support regional clusters of industrial decarbonization projects.

Our Work in California
In California, RMI and the Mission Possible Partnership work on accelerating low-carbon solutions for industry and heavy transport. We provide technical assistance to first-of-a-kind (FOAK) decarbonization projects and for the ecosystem of policy, finance, infrastructure, and community engagement needed for success.
