Detailed explanation-1: -Among all greenhouse gases, CO2 is responsible for 60% of greenhouse gas effect.
Detailed explanation-2: -Carbon dioxide is currently responsible for over 60% of the “enhanced” greenhouse effect, which is responsible for climate change. This gas occurs naturally in the atmosphere, but burning coal, oil, and natural gas is releasing the carbon stored in these “fossil fuels” at an unprecedented rate.
Detailed explanation-3: -Carbon dioxide is the primary gas emitted, though fuel combustion also releases small amounts of methane and nitrous oxide, and vehicle air conditioning and refrigerated transport release fluorinated gases too.
Detailed explanation-4: -CO2 accounts for about 76 percent of total greenhouse gas emissions.
