Notes de l'éditeur
The demand for transport is going to get several times greater globally as 3 rd world countries economies improve
Anthropogenic – man made. CO2 is not the only greenhouse gas but is the one that is relevant to the transport sector
Transport is 23% of total but this excludes international aviation and shipping
Domestic aviation 0.9MtC, international aviation 9.3MtC
HGVs and vans are important as cars
Effects of improvements in engine and fuel technologies recently… this is New Cars not the current car fleet
International Aviation … the elephant in the cupboard
Even if we cut other transport emissions we will see a substantial growth in aviation which has a doubling effect on GHG because of Reactive Forcing effects of contrails producing extra water vapour in the atmosphere (water vapour is a greenhouse gas) and NOx impact on ozone in atmosphere
