To fight climate change, California approves seaweed that cuts methane emissions in cow burps
San Francisco Chronicle
California dairy farms will soon be able to feed their cows seaweed to fight climate change after the state Department of Food and Agriculture approved the use of a seaweed feed shown to reduce methane emissions from cow burps, the first in the U.S. to do so.
On Friday, Blue Ocean Barns, which produces the red seaweed at a farm on the Big Island of Hawaii, announced that the supplement had been approved for use on both conventional and organic dairy farms. Called Brominata, the red seaweed variety has been shown to cut methane emissions in dairy cows by 52% over 50 days but so far has been used only in trials.
“California is being really bold and putting their money where their mouth is in their desire to have a sustainable dairy industry,” said Joan Salwen, CEO of Blue Ocean Barns. “They were very much first to grant a license and approve labels and get us into the market.”
