The California Air Resource Board (CARB) is an organization entrusted with educating and safeguarding communities from the harmful effects of air pollution and develops programs that combat climate change. Like California, many states have instituted environmental regulations to help limit the amount of short-lived climate pollutants (SLCPs), like HFCs, into the environment. However, its CARB that has led the charge and has driven innovation that has led to developments in cleaner fuels and low- and zero emission vehicles. Their work extends into an effort to further reduce HFC emissions by 40 percent by 2030, and they have proposed an ambitious second phase of regulations that will significantly impact the commercial refrigeration industry.
Refrigerants with a GWP greater than 150 will not be allowed in new, stationary refrigeration systems charged with more than 50 pounds.
Refrigerants with a GWP greater than 750 will not be allowed in chillers (including process chillers) greater than -15 °F and ice rinks, effective January 1, 2024.
Refrigerants with a GWP greater than or equal to 2,200 will not be allowed in new chillers ranging from -15 °F through -58 °F, effective January 1, 2024.
Companies owning or operating 20 or more retail food facilities with refrigeration systems charged with more than 50 pounds must collectively meet a 2,500 GWP average or 25% percent greenhouse gas emission potential (GHGp) reduction over 2018 levels, by 2026.
Companies owning or operating 20 or more retail food facilities with refrigeration systems charged with more than 50 pounds must collectively meet a 1,400 GWP average or 55% greenhouse gas emission potential (GHGp) reduction over 2018 levels, by 2030.
Companies owning or operating fewer than 20 retail food facilities with refrigeration systems charged with more than 50 pounds must collectively meet a 1,400 GWP average or 55% greenhouse gas emission potential (GHGp) reduction over 2018 levels, by 2030.
Get ready! Other states are following California's actions.
California has been the leader in instituting rules and regulations that support the protection of the environment, but many states have followed suit and are likely to adopt similar regulations. The U.S. Climate Alliance, which was established in 2017, is a bipartisan coalition of governors committed to reducing greenhouse gas emissions. What was once a commitment of 16 states and Puerto Rico has grown to 25 members, representing 55 percent of the U.S. population and an $11.7 trillion economy. This Alliance has pledged to implement policies aiming to reduce greenhouse gas emissions, track and report their progress and facilitate new and existing policies to reduce emissions and promote clean energy deployment.
CARB – The Refrigerant Management Program (RMP) requires facilities with refrigeration systems containing more than 50 pounds of high-GWP refrigerant to conduct and report periodic leak inspections, promptly repair leaks; and keep service records on site. The regulation also requires service practices intended to minimize refrigerant emissions. Read More>
