Agriculture produces 25% of human-caused greenhouse gas emissions—as much as electricity generation. Spark is currently working on two of the largest blockers to bring these emissions below zero: a lack of accessible greenhouse gas measurement technology and also solutions for livestock enteric methane production—which is ~25% of global anthropogenic methane emissions, driving ~0.1°C and counting of current warming. Current enteric methane commercial solutions incompletely address the very small portion of methane emissions from cows on feedlots and similar, globally estimated at ~2-5% (but getting better data here is another challenge to address).  Addressing the remaining 95%+ requires systematic research, international development, and sociology investments.

Catalyzing US Leadership in Livestock Enteric Methane ("Cow Burps")

Cows burp as much greenhouse gas methane in the United States as its fossil fuel infrastructure leaks. Developing anti-methane solutions could simultaneously improve cattle productivity by about 6%, and globally avoid 0.25°C of global temperature increase in 2100. The US has an opportunity to lead through 2023 Farm Bill research funding and capacity-building.
