Detailed explanation-1: -Transportation accounts for about 20% of greenhouse gas emissions, with road transportation accounting for three-quarters of this share. Aviation and maritime transportation account for 11%, respectively.

Detailed explanation-2: -The transport sector is responsible for approximately one quarter of greenhouse gas emissions. 95 per cent of the world’s transport energy still comes from fossil fuels.

Detailed explanation-3: -The transportation sector emits 14% of global greenhouse gas emissions. Most of this involves fossil fuels burned for road, rail, air and marine transportation.

Detailed explanation-4: -India’s transportation sector contributes about 10 per cent of total national greenhouse gas (GHG) emissions and road transportation contributes about 87 per cent of the total emissions in the sector.

Detailed explanation-5: -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.
