for future reductions. Kyoto requires a 12.5% reduction in the CO2 equivalent for all 6 greenhouse gases that are considered. The government's predictions are that the main savings, compared with the base year, will be:
Carbon dioxide: 17.2 Megatonnes carbon equivalent
Methane: 14.3 MtC
nitrous oxide: 7.6 MtC
but that methane saving is already 57% of the base level; and the nitrous oxide 41%. It won't be possible to achieve those kind of savings again in the future - the government estimate is for another 1.3 MtC reduction in methane by 2020, and no further reduction in N20. The reduction in carbon dioxide came almost all from 1990 to 1995 when many coal fired power stations were replaced by natural gas fired ones. The UK's CO2 output is now
above its level in 1995, and the government predicts it will fall a little between now and 2010 - but then increase a little. The prediction for 2020 is no better than for 2010.
And the kicker is: the Kyoto figures for a country don't include
international air travel, only domestic. Now, UK domestic air travel isn't that much - it's a small group of islands, a bit smaller than California (London to Glasgow is roughly the same as Los Angeles to San Francisco, and those are the 2 large cities furthest apart). But we do, especially recently, do a lot of international air travel - budget airlines have grown immensely, taking us on short breaks to various parts of Europe. And the government is busy planning new runways and airport terminals to support the growth in air travel that
it wants. And that growth won't spoil the Kyoto numbers for the UK, so they don't worry about it.
