Notes: Emission estimates relate to energy end use (i.e. do not include emissions from fuel supply and processing, or
from power generation for electric railways).
‘Motor vehicles’ include all road vehicles plus off-road recreational vehicles. ‘Aviation’ includes emissions
from general aviation. ‘Maritime’ includes emissions from small pleasure craft and ferries, and from all fuel
consumption for the coastal shipping task. Emissions due to military transport are excluded.
