Q412. What do the quantities of GHG emissions mean in everyday terms?
A412. EPA's greenhouse gas equivalencies calculator can help you translate GHG emissions measurements into easily understood concrete terms, such as "equivalent to the annual carbon dioxide emissions of 183,000 cars." Note that the EPA's GHG Reporting Program provides emissions information in metric tons of CO2 equivalent, so be sure to select metric tons when using the equivalency calculator.
