Greenhouse gas emissions are gasses in the atmosphere that trap heat near the earth's surface. The Environmental Protection Agency has taken an inventory of these gasses since 1990 and posted them on this website. Learn which gasses are bad, how they get into the air, and the rates at which they emitted and removed from the atmosphere.
