“CO2 emissions vary by fuel type. Gasoline and diesel engines emit CO2 based on their combustion processes. Electric vehicles produce zero tailpipe emissions but may indirectly contribute through electricity production. Calculating emissions involves considering distance driven and fuel efficiency. It’s crucial to promote fuel-efficient and electric vehicles to reduce overall CO2 emissions.”
