Okay, let's look at methane. So, now methane has 28 times the global warming potential of CO2. So when biogas comes out of landfills or municipal waste digesters, it is roughly 50-50 CO2 and methane. Now, what is the difference between the biogas that comes out of a biodigester or a landfill versus natural gas that comes out of the ground? Literally nothing. There is no difference. Natural gas is also about 50% CO2, 50% methane. Biogas is also approximately that.

So what makes biogas renewable versus natural gas not renewable? The only difference is the life cycle of biogas—like the waste that goes in and the gas that is produced—that time is much shorter compared to natural gas. Natural gas has the same raw ingredients. It's the same organic matter: the plants, the shrubs, and all of this stuff. Over millions of years, it goes down, and then, by pressure and heat, it transforms into fossil fuels. And then that gas, that associated gas that comes out, is just as renewable as biogas.

This is important.
