Projects will will reduce greenhouse gas emissions from manure on California dairy and livestock farms
“Methane is one of the most potent greenhouse gases there is, but it’s also one that we know how to reduce,” said CDFA Secretary Karen Ross. “The projects funded through AMMP and DDRDP today will have an important impact on California’s methane emissions and help us meet our SB 1383 target of a reduction of 40 percent below 2013 levels by 2030 — among the most ambitious goals in the world.” (Public Domain)
SACRAMENTO — The California Department of Food and Agriculture (CDFA) today announced that it has awarded $37.65 million in grant funding to 41 methane reduction projects across the state. These projects, part of the Alternative Manure Management Program (AMMP) and the Dairy Digester Research and Development Program (DDRDP), will reduce greenhouse gas emissions from manure on California dairy and livestock farms.
In line with the Budget Act of 2021’s guideline to prioritize AMMP, 27 AMMP projects totaling $18.94 million and 14 DDRDP projects totaling $18.71 million in grant funds are being awarded, and the projects will contribute $74.1 million in matching funds.
These grants enable recipients to improve their manure management practices and are anticipated to result in a total estimated annual greenhouse gas (GHG) reduction of 233,393 metric tons of carbon dioxide equivalent (MTCO2e).

“Methane is one of the most potent greenhouse gases there is, but it’s also one that we know how to reduce,” said CDFA Secretary Karen Ross. “The projects funded through AMMP and DDRDP today will have an important impact on California’s methane emissions and help us meet our SB 1383 target of a reduction of 40 percent below 2013 levels by 2030 — among the most ambitious goals in the world.”
Dairy manure produces methane when it decomposes. Methane is a powerful GHG that traps 25 times more heat in the atmosphere than carbon dioxide within a 100-year timeframe, contributing to global warming.
Dairy digesters help capture methane emissions and use them to produce electricity or natural gas. Alternative manure management practices such as scrape collection instead of flush or solid separation so more manure is handled in a dry form also help to significantly reduce methane emissions.
Implementing these practices can also provide other important co-benefits such as reducing odor and certain air pollutants like reactive organic gases or nitrogen oxides (NOx), improving the efficiency of water recycling and reuse for irrigation, and producing compost from manure solids that can be used for fertilizer and animal bedding.
This latest round of grants brings the total of AMMP and DDRDP projects to 273 since 2015. Together, these projects are anticipated to reduce an estimated 2,555,727 metric tons of GHGs per year, which is equivalent to removing more than 550,600 cars from the road.
In addition to these investments, CDFA partnered with the California Dairy Research Foundation on a proposal that was recently awarded a grant of up to $85 million by USDA through its Climate Smart Commodities Program. This award will support AMMP-related projects and activities focused on building climate-smart dairy markets and provide financial incentives for California dairy producers to reduce both methane emissions and nitrogen surplus. These projects will also leverage matching funding from non-federal sources.
