What are CO2 equivalents?

We consume electricity, travel, and heat our homes—all of which generate emissions that affect our atmosphere and impact the climate. These emissions include not only_CO₂, but also other climate-impacting gases such as methane and nitrous oxide. They can be calculated and expressed in_{CO₂ equivalents}. Methane, for example, is also released in excessive quantities as a result of human activity. 1g of methane is approximately 25 times more climate-impacting than 1g_{of CO2}. 1g of methane therefore equates to 25g_{of CO2 equivalents}.
