CO2 Equivalent Emissions is a standard which allows comparison of different amounts and types of greenhouse gas and particulate pollution. A figure for CO2 Equivalent Emissions is calculated by determining the global warming impact of each type of emission, and converting this to the amount of CO2 which would have the same impact. Adding these CO2 equivalent numbers gives a single CO2 Equivalent Emissions figure to enable legitimate comparisons between processing facilities, industries, and countries.
