Wow. This weekend I was going to write about the fact that aeroplanes only make up a tiny proportion of CO2 emissions. But I had to give it up after I couldn’t find the actual figures. I was sure I’d read it in a recent issue of The Economist or something, but I couldn’t find it. I might have made it up.
But ranty Alex has written a post about it, and it’s true!
…if you get the data, you’ll find that, when you interpolate the emissions from aviation fuel uplifted from the UK, it makes up 5.5 per cent of the UK’s CO2 emissions. (Comparison – electricity generation is 30 or so, road transport a quarter)
It is a cracking post. Alex goes on to ask why environmental campaigners are so deseperate to cut aviation when even if flying were ever to be completely eradicated (which I think most whould agree is not even remotely on the cards) we would still be left with 94.5% of that mucky CO2 in the air.
So why would you go for the hardest problem first, especially when it only represents 5 per cent of the problem?
In my opinion, much more energy could be saved, and less CO2 emitted, if people would switch off unused lights, switch off their computers overnight, don’t leave their televisions on stand by, and so on and so on. Why do shops leave their lights on overnight? That makes me mad.
