CDFA, Secretary Ross join announcement of methane reduction efforts with subnational governments at COP28

From a California Air Resources Board News Release

California officially kicked off a new international climate initiative that creates a partnership of subnational governments that are committed to reducing methane at the United Nations Climate Change Conference (COP28) hosted in Dubai.

The effort, which was initially announced in September during Climate Week, has expanded to 15 signatories, which include additions from Brazil, Canada, South Korea, Bolivia, Germany, Spain, and the United States.

The Subnational Methane Action Coalition creates collaboration with jurisdictions that oversee and regulate key sources of methane such as agriculture, energy and landfills to share goals and best practices in reducing the short-lived climate pollutant that accounts for almost 30% of current global warming and is 80 times more potent than carbon dioxide over a 20-year period.

“The science is clear that tackling methane emissions is one of the best investments we can make to fight climate change now and produce benefits in the near future to leave a better planet for generations to come,” said Liane Randolph, Chair of the California Air Resources Board. “California is ready to partner with governments across the world to implement actionable and effective solutions.”

“With leadership from our dairy families, California agriculture has been working to reduce methane emissions for a number of years. In addition, our efforts will require global solutions, bold ideas, and international partnerships to achieve the maximum reductions needed to accomplish our shared climate change goals,” said Karen Ross, California Secretary for the Department of Food and Agriculture.

California set a goal to reduce 40% of its methane emissions by 2030 compared to 2013 levels, and is leading the country with innovative solutions, including $100 million in funding to support a constellation of satellites that can monitor for large methane plumes. The California Air Resources Board (CARB), California Environmental Protection Agency (CalEPA), California Natural Resources Agency (CNRA) and California Department of Food and Agriculture (CDFA) collaborate in the state’s international engagements on methane.

Since methane is a potent greenhouse gas with a short atmospheric lifespan, methane emissions reductions can reduce the effects of climate change in the short term, and are critical for putting the world on a path to limiting warming by 1.5°C.

Signatories of the Coalition include:

• California (US)
• Queretaro (Mexico)
• Gauteng (South Africa)
• Espirito Santo (Brazil)
• Cross River State (Nigeria)
• Yucatan (Mexico)
• Delhi (India)
• Colorado (US)
• Rio Grande do Sul (Brazil)
• Pernambuco (Brazil)
• Baden-Württemberg (Germany)
• British Columbia (Canada)
• Santa Cruz (Bolivia)
• Andalusia (Spain)
• Gyeonggi (South Korea)

Other partners in the effort include the Climate Group, which convenes subnational governments for climate action through the Under2 Coalition, and the UC Berkeley Center for Law, Energy, and Environment, which will work with state agencies and Initiative members to create action plans, track progress, organize regular peer-to-peer learning opportunities, and share best practices.

Research shows that lowering methane emissions can prevent up to 0.3°C of warming by 2050. While over 150 countries have agreed to collectively reduce global methane emissions by at least 30% below 2020 levels by 2030 through the Global Methane Pledge of 2021, meeting this target will require significant efforts from subnational jurisdictions.
