The global aviation industry decided in 2050 to halve the final release of combustion products in comparison with 2005 figures, the year in accordance with the plan, adopted 22 September 2009 the head of British Airways, Mr. Willie Walsh. Mr. Walsh, who will announce the initiative in New York during the United Nations forum on the global climate change, said that such decision is "the best solution for the entire planet and should be taken at the December summit in Copenhagen, at which heads of state must come up with new proposals to limit emissions of harmful substances into the atmosphere, which should replace the Kyoto treaty in 1997. "Emissions from the combustion products of global aviation were not included in the Kyoto Protocol 12 years ago," – said Mr. Walsh. "Today we have an opportunity to correct this omission – and we must take advantage of it." However, the proposed plan, likely will not accept activists against environmental protection. By choosing to compare the performance to reduce the number of combustion products in 2005, the aviation industry to offer reduction, starting from higher starting numbers than if the comparison was chosen in 1990, used by the Intergovernmental Panel on Climate Change. Although the airlines suggest that the greenhouse gases effects, are released into the atmosphere, make up only three per cent, a figure likely to rise significantly in the near future, unless steps are taken to prevent it.
