🗞️ Driving the news: Scientists at the UK’s Pirbright Institute are developing a vaccine to reduce methane emissions from cows, a major source of greenhouse gases
• The project, backed by the Bezos Earth Fund with $9.4 million, aims to cut emissions by at least 30%
• Unlike feed additives, the vaccine would be a long-term solution requiring just a single dose
🔭 The context: Livestock accounts for about a third of human-related methane emissions, a gas 28 times more potent than CO₂
• Previous attempts to tackle the issue include feed additives and selective breeding, but these have limitations
• The vaccine would trigger antibodies to suppress methane-producing gut bacteria in cows, but its effectiveness and potential side effects remain under study
🌍 Why it matters for the planet: Reducing methane from cattle could significantly lower agriculture’s contribution to climate change
• Methane is responsible for about 30% of global warming, and solutions targeting livestock emissions are crucial for sustainable food production
• If successful, the vaccine could be a breakthrough in cutting agricultural emissions
⏭️ What's next: Scientists must prove the vaccine is effective, safe for cows, and viable for mass deployment
• Challenges include ensuring consumer acceptance and combating misinformation, as seen with past feed additive controversies
• Researchers aim to develop a proof of concept that could lead to commercial use
💬 One quote: “The appeal of a vaccine is that it’s a very well-adopted, common practice… and people know about the benefits of vaccination for animal health generally.” — John Hammond, Director of Research at The Pirbright Institute
📈 One stat: A single cow produces about 200 pounds of methane per year, contributing to a third of human-related methane emissions
