Non-CO2 Greenhouse Gases

Carbon dioxide (CO2) is by far the most common greenhouse gas, currently accounting for over three-quarters of all U.S. emissions. It is also the most well-known greenhouse gas and tends to dominate the conversation about the climate crisis. However, other lesser-known greenhouse gases, including methane, nitrous oxide, and fluorinated gases, also contribute to climate change. Driving down these greenhouse gases, in addition to curtailing carbon emissions, is key to solving the climate crisis. This three-part article series covers the science behind non-CO2 greenhouse gases, their main sources, and federal policies to address them.
