How much CO2 is emitted by the transport sector?
The transport sector is one of the more obvious emitters of CO2 – obvious because you and I emit it, and you and I can see it being emitted!
How much CO2 does the transport sector as a whole emit globally?
According to estimates, in 2015 transport accounted for about 21% of total global greenhouse gas emissions of about 35 billion tons (35,000,000,000 T). That would be about 7.5 billion tons (7.5 billion tons) of CO2 every year.
Of this, the air transport sector emits about 0.75 billion tons (about 10% of total transport), water transport emits about 1.3 billion tons (17% of total transport emissions), and the rest about 5.5 billion tons of CO2 (73% of total transport emissions) are emitted by road transport.
Some estimates suggest that the share of the transport sector to total CO2 contributions could significantly increase in the next 15 years – emissions from transport are estimated to increase by about 30% between 2015 and 2030.
