Global warming potential of greenhouse gases relative to CO2

What you should know about this indicator
- Global warming potential (GWP) values are used to convert greenhouse gases into a carbon dioxide equivalent metric by multiplying emissions in mass terms by their respective GWP factors.
- For example, a GWP value of 25 for a certain gas means that one tonne of that ags has 25 times the warming impact of one tonne of carbon dioxide.
