Total methane emissions have declined since 1991, but methane emissions from livestock are up

The recently passed Inflation Reduction Act includes a number of provisions meant to reduce greenhouse gas emissions in the US.

Part of that effort is $29.6 billion in funding for programs directly related to reducing methane emissions.

As a greenhouse gas, methane is 25 times as effective as carbon dioxide at trapping heat in the atmosphere. It’s the second largest source of greenhouse gas emissions in the US, after carbon dioxide.
