A Greenhouse Gas Cheat Sheet


Courtesy of the Carbon Catablog; a handy guide to help you out when you are talking about them nasty gases!

The Gases

There are greenhouse gases caused by humans (anthropogenic) and those caused by Mother Nature.

Unless you have some seriously good connections, the only gases we can change are the ones emitted by us. To help us along, the Kyoto Protocol has selected six major greenhouse gases (2005) that we need to either reduce or neutralize.

Carbon dioxide (CO2), the most dominant and notorious greenhouse gas produced by the burning of fossil fuels, deforestation…

Methane (CH4), otherwise known as “swamp gas,” is that which is emitted from animal manure, garbage dumps…

Nitrous oxide (N2O) is laughing gas, but its main form comes via fertilizer and car exhaust…

Hydrofluorocarbons (HFCs) are small but potent, and found in your kitchen fridge, air conditioners, foam-blowing agents, aerosol propellants…

Perfluorocarbons (PFCs) are by-products of aluminum smelting, and are used for manufacturing semi-conductors. They have become substitutes for ozone depleting chemicals… a lesser of two evils?

Sulfur hexafluoride (SF6) is the most potent greenhouse gas. You’ll find it in Nike Air shoes, car tires, electrical insulation…
