The earlier...‘Carbon dioxide equivalents’ try to correct for the fact that one unit (e.g. a tonne) of a given gas doesn’t have the same same impact on warming as another. We therefore multiply the emissions of each gas by its ‘global warming potential’ (GWP) value: this measures the amount of warming one tonne of that gas would create relative to ...

Greenhouse gases trap heat and make the planet warmer. Human activities are responsible for almost all of the increase in greenhouse gases in the atmosphere over the last 150 years. 1 The largest source of greenhouse gas emissions from human activities in the United States is from burning fossil fuels for electricity, heat, and transportation.CO2 tanks are used with welding equipment, beer kegs, paintball guns, T-shirt guns and soda streams.
