The paper, authored by researchers at UC Davis affiliated with UC Agriculture and Natural Resources, concludes that efforts are on track to achieve the state’s world-leading target for reducing dairy methane emissions by 40% by 2030.

The report, written by distinguished professors of livestock emissions and agricultural economics, takes a comprehensive look at progress and projections, expanding upon the analysis of progress previously conducted by the California Air Resources Board. By documenting achievements to date, additional reduction efforts already funded, historic and current economic trends, and the projected availability of new solutions, the analysis lays out a workable path toward meeting California’s goal. The pathway shows that California dairy farms are on track to achieve the full 40% dairy methane reduction goal and will reach “climate neutrality” by 2030. Climate neutrality is the point in which no additional warming is added to the atmosphere.

“This analysis shows that California’s dairy sector is well on its way to achieving the target that was established by SB 1383 in 2016,” said CDRF’s Executive Director Denise Mullinax. “With much important work still ahead, a clear understanding of this pathway helps dairy farmers, policy makers, researchers, and other partners make decisions to strategically press forward.”

The report outlines the need for continued implementation of California’s four-part strategy for dairy methane reduction: farm efficiency and herd attrition, methane avoidance (alternative manure management), methane capture and utilization (digesters), and enteric methane reduction. Continued alignment of state and federal climate-smart agricultural approaches and incentives will also be critical to maintaining progress.

“Milk demand is growing, and California is among the world’s low-cost suppliers of dairy products. It follows that effective California policy to reduce dairy greenhouse gas emissions must recognize that measures that cause milk production to exit the state do not mitigate global climate change,” said study co-author Daniel Sumner, Distinguished Professor in the Department of Agriculture and Resource Economics at UC Davis. “Therefore, measures to help off-set mitigation costs, provide positive incentives for adoption of low-cost emission-reducing practices, and help stimulate innovation in methane reduction, are the economically efficient approaches.”

The paper recognizes that enteric methane from the dairy and other livestock sectors is a significant source of greenhouse gas emissions in the U.S. and California. Several feed additives are expected to become commercially available in the next several years, which could be used to reduce enteric methane emissions from California’s dairy herd.

“Adoption of enteric feed additives will become a valuable tool for dairy value chains to meet their greenhouse gas reduction goals,” said co-author and professor Ermias Kebreab, associate dean of global engagement and director of the World Food Center at UC Davis. “While this report provides only a broad overview of some of the most promising solutions, there is an incredible amount of research being conducted at UC Davis, nationally and internationally. The dairy industry, global food companies, state and federal agencies, and others continue to invest heavily in supporting enteric mitigation research efforts.”

The report finds that methane reductions from California’s programs and projects in place today, coupled with the implementation of a moderate feed additive strategy to reduce enteric emissions, is on track to reduce between 7.61 to 10.59 million metric tons of methane (CO2e) by 2030, all from the dairy sector alone.

The collective investment in California’s dairy methane reduction effort — from public and private funding — now exceeds $2 billion and counting. The California dairy sector, in coordination with the California Department of Food and Agriculture, was recently awarded up to $85 million by the United States Department of Agriculture under the Partnerships for Climate-Smart Commodities. The funding will leverage additional matching state funds and private capital investments, for a total of more than $300 million in new investment.

“It is important to highlight California’s investments and success to date as an example of what is possible within the global livestock sector,” said co-author Frank Mitloehner, UC Davis animal science professor and air quality specialist in Cooperative Extension, and director of the UC Davis CLEAR Center. “California dairy farmers have demonstrated tremendous progress toward the state’s methane reduction goal over the past several years. Given the short-lived nature of methane, this rapid reduction is an important contribution to the global effort to quickly limit climate warming.”

UK stocks slipped on Monday as investors refrained from making risky bets ahead of key central bank decisions this week, while gains in Unilever limited losses on the FTSE 100 after the consumer goods giant announced a new chief executive officer.
