Modernizing California's industrial boilers will bring cleaner air and save lives.

California is home to the largest manufacturing sector in the country, where all kinds of essential everyday goods are made in factories across the state. These industrial facilities support more than 1.24 million jobs and provide a critical underpinning to our state’s economy. However, these facilities largely rely on polluting industrial boilers that worsen smog and threaten the health of nearby communities.

California’s Clean Heat Opportunity

California has the technology to clean up this pollution. Industrial heat pumps, electric resistance boilers, and heat batteries are more efficient and can meet the needs of a wide range of manufacturers and large facilities such as hospitals and universities. These zero-emissions technologies perform better, faster, safer, quieter, and cleaner than the 19th-century combustion technologies they replace. California manufacturers and hospitals are already adopting this technology. California can’t afford to fall behind and lose its competitive edge.

A major driver of California’s air pollution


Each industrial boiler emits an average of 2.2 tons of NOx annually, roughly equivalent to the emissions from 136 gas-powered cars.

Disproportionate exposure in environmental justice communities


92% of California’s industrial boilers are located in regions that already exceed federal ozone standards

Meanwhile, the majority of the industrial boilers in California are in or near disadvantaged communities

Transitioning industrial facilities to zero-emission technologies in CA can deliver major health benefits statewide. By 2050, industrial heat pumps can:

  • Deliver $47.5 billion in cumulative health benefits

  • Prevent 3,220 premature deaths

  • Prevent nearly 2 million asthma attacks
