How much pollution does natural gas produce in California per year?

Natural gas combustion in California contributes to greenhouse gas emissions, primarily carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). In recent years, California has aimed to reduce its reliance on natural gas to meet climate goals, targeting a reduction of greenhouse gas emissions to 40% below 1990 levels by 2030. In 2020, natural gas power plants emitted approximately 30 million metric tons of CO2 in the state. However, the exact annual pollution levels can vary based on energy demand and regulatory changes.
