The UK government is consulting on its approach and principles to reach net zero aviation by 2050. Essentially the solutions proposed are based around bio-fuels and new technologies, with little emphasis given on reducing demand for air travel – which is assumed to continue to expand by 3% per year.
The Government’s own Climate Change Committee recommends managing passenger numbers to allow only slow growth of about 0.7% per year from 2018 to 2050. In the UK, 70% of flights are made by a wealthy 15% of the population, with 57% not flying abroad at all.
