Scientists at COP30 are promoting vaccines and dietary additives, such as seaweed and garlic, to reduce methane emissions from the world's one billion cows. Methane is estimated to be 80 times more potent than carbon dioxide in trapping atmospheric heat. Critics argue these measures unfairly target the agricultural sector and livestock owners while ignoring larger industrial CO2 sources.
Researchers are testing a specific red seaweed, Asparagopsis taxiformis, as a feed additive for livestock to eliminate methane emissions from cow burps. The "methane tamer" product is expected to reach U.S. supermarkets by early 2025 as a low-carbon beef option.

Chef Callum Munro and climate activist Shona Cameron are promoting seaweed as a renewable alternative to fish and meat on the Scottish Isle of Skye. The initiative introduces "sea spaghetti" and other algae-based recipes to local schools to encourage sustainable eating habits. Proponents argue seaweed is a year-round vegetable of the sea that requires no fresh water or fertilizer to grow.
