The California Air Resources Board (CARB) invited participants to a public workshop highlighting results from research studies on landfill methane emissions. CARB has supported a wide variety of research projects related to landfill methane emissions in California for over a decade. These studies employed an assortment of different technologies and spanned scales from individual landfills to statewide surveys. In this workshop, CARB staff summarized these studies and the current state of landfill methane emissions science in California, and highlighted the strengths and limitations of existing data as well as technologies employed thus far. CARB also solicited feedback on potential future research projects. Public input on methods, technologies, and priorities will help CARB fill existing knowledge gaps and has the potential to inform future quantification and/or mitigation efforts.  

Background

Methane is an important greenhouse gas that is responsible for more than 25 percent of current global warming. Methane’s relatively short lifetime in the atmosphere (about a decade) means that emission reductions will result in near-term reductions in methane concentrations in the atmosphere, slowing the pace of global temperature rise. Landfills are known to be among the most important human-caused sources of methane globally, and are estimated to account for about ten percent of methane emissions in California.
