Subterfuge
“Under the Climate Change Act, the UK is committed to cutting all its climate-changing emissions by 80%, based on 1990 levels, by 2050.
However, international flights and shipping are not included in the targets.”
Sky: Maybe this is what is known as “greenwash?” Is there to be no end to the subterfuge?
“In the European Union, greenhouse gas emissions from aviation increased by 87% between 1990 and 2006.[4]” ^ “Climate change: Commission proposes bringing air transport into EU Emissions Trading Scheme” (Press release). EU press release. 2006-12-20. Retrieved 2008-01-02.
“Much of the uncertainty about calculating the environmental impact of aviation emissions derives from the fact that emissions at altitude can instigate a host of chemical reactions in the atmosphere, which each have global warming and cooling effects over a variety of timescales, varying from less than 1 day to several hundred years.3 The overall effect is certainly one of an increased warming effect compared to emissions at ground level, but the extent of this remains open to debate, both in terms of how to calculate the magnitude of this effect, and what the value should be. Historically the Intergovernmental Panel on Climate Change (IPCC) quoted a value of 2.7 for this multiplier, with a range of 2-4.4”
