Note also the colourful expression 'carbon time bomb'
Aviation produces about 2.5 per cent of mankind's emissions of carbon dioxide, the main greenhouse gas that scientists say is heating up the planet
If aviation emissions (at about 900 million tonnes of CO2 last year) were a country, it would be the sixth-largest polluter.
The biggest expected reductions, though, will come from growing use of sustainable biofuels and offsetting.
The concern, though, is whether huge demand for biofuels will compete for land used to grow food or lead to over-intensification of land use or further deforestation.
offsetting emissions. This basically means paying someone else to reduce international aviation's emissions growth.The scheme is called Corsia, or Carbon Offsetting and Reduction Scheme for International Aviation. Under Corsia, the international aviation sector will have a cap on emissions from this year. Any emissions growth, expressed in tonnes of CO2, will be divided up among participating airlines, which will have to purchase carbon offsets from approved emissions reduction projects equal to the emissions growth of the sector. ..These projects could be more efficient cook stoves, forest preservation projects, and wind or solar farms. The idea is that these projects receive financing from buying carbon offsets and this cash flow makes them viable. Over their lifetime, the projects reduce or prevent CO2 emissions because of the cleaner technology they use.

1 Qn: Air travel should be discouraged, not promoted. To what extent do
you agree? (Cam. 2008)
