Emissions from aviation currently account for about 3% of total EU greenhouse gas emissions, but they are increasing fast – by 87% since 1990 – as air travel becomes cheaper without its environmental costs being addressed.
Praegu moodustavad õhutranspordi tekitatud heitkogused umbes 3% ELi kasvuhoonegaaside üldisest heitkogusest, kuid see suureneb kiiresti – 87% võrra alates 1990. aastast – kuna ilma keskkonnakulusid arvestamata muutuvad lennureisid odavamaks.
