Hi, it's Greg Dalton.

I'd like to hear your comments on the show, topics we should cover, and guest suggestions.

This is Climate One. I'm Greg Dalton. Today, Arianna Brocious and I are digging into compost and cow poop. Yeah, manure really matters because nationally, 37% of methane emissions come from cows.

A lot of that is actually cow burps, which we'll get into later,

but a big chunk is cow poop.

Right, and not just manure. Landfills release a lot of methane too. In fact, 17% of all

U.S. methane emissions come from landfills, and most of that is from food waste.

In a 20-year time frame, methane has 80 times more warming power to the

climate than carbon dioxide. California has a new law that aims to tackle methane from these two

main sources, cows and landfills. We're spending today's show talking about it because California

has a track record of setting national policy, or at least leading by example.

Last year at COP 26 in Glasgow, more than 100 countries, including the U.S., signed the

Methane Pledge, promising to reduce methane emissions by 30% by 2030.

The California law targets a 40% reduction in the same time frame, so it's ambitious.

It is, and the more I learn about this law known as Senate Bill 1380s, a 40% reduction in the same time frame. So it's ambitious.

It is.

And the more I learn about this law known as Senate Bill 1383 or SB 1383, the more interesting and complicated it gets.
