If everysingle person and company in the uk, was 100% efficiant (sp) which as we know is imposible, then the world as a whole would be 2% cleaner.. woo hoo well done uk. But the realism is we are prob cuttin immisions by 20% if we are lucky.. so the uk cuts global immissions by 0.8 % again well done uk.. If you ask me, i'd rather not loose performance cars/bike, i'd rather have a cheaper boiler installation ect.. for the sake of 0.8%.. what difference will that make? not a lot of course not, we need everyone.. the usa, china all that, to do the same as our government, then maybe we will get somewhere.  We have already lost our seasons in this country(uk).. summer lasts about two weeks and is stupidly hot, rains most of the time, and it's not very cold in winter. ..it's all downhill from here really.
