U.S. Methane From Livestock Digestion (2012)

Gridded 2012 EPA Methane Emissions - Enteric Fermentation
atmosphere NASA VEDA COG
In plain English

What it measures. A map of 2012 methane emissions across the U.S. from enteric fermentation, the natural digestion in animals like cattle that produces methane.

How it's made. Compiled by the U.S. Environmental Protection Agency into a gridded national emissions inventory.

How & where you'd use it. Helps researchers and policymakers see where livestock are a major methane source.
