A22. 25,000 mtCO2e are equivalent to emissions from the annual energy use of approximately 2,300 homes. The threshold is also roughly equivalent to the annual greenhouse gas (GHG) emissions from approximately 4,600 passenger vehicles. It is also equivalent to just over 58,000 barrels of oil consumed or 131 railcars’ worth of coal. For more information about GHG emissions equivalencies in general you may access EPA’s Greenhouse Gas Equivalencies Calculator.
