Cow burps are one of climate’s strangest and most stubborn problems. Methane is an extremely potent greenhouse gas, and cattle are responsible for about 30 percent of global methane emissions. For years, the basic answer has been: eat less beef and drink less milk.

Kathryn Polkoff, PhD, co-founder and CEO of Hoofprint Biome, thinks there is a better way. Hoofprint uses natural enzymes to reshape the cow’s rumen microbiome, cutting methane production while boosting dairy milk yield and beef cattle weight gain. No harsh chemical feed additives. Just a solution that helps farmers produce more with less methane.

In Supercool’s first live recording, Josh talks with Kathryn at Raleigh-Durham Startup Week’s inaugural Climate Tech Day about cow burps, commercializing agricultural climate tech, and why Hoofprint could not exist without AI. It is a climate story about biology, business, and turning wasted energy into value.
