This month the government published our latest national CO2 statistics. They are quite interesting to look at, you can read the full press release here or just have a quick look at the chart above.

The headline is that CO2 is going in the right direction and everyone is rather pleased. In total we seem to have cut our national carbon footprint by 28%. That's the kind of good news we like to hear, if things are indeed what they seem.

But of course, things are not what they seem. The first big sleight of hand is to have excluded from the data the only 2 major sectors where carbon emissions are growing massively: shipping (up 17% since 1990) and aviation (up 109%). When these are included, the total UK saving falls to 25%.

But 25% is still good right? Well, it sounds good, but what's strange is that a big chunk of this saving (about a third of it, actually, or about 8% points) has been delivered in the last two years. And because the reporting is all a year in arrears, that means between 2007 and 2009. Hmmm. Can anyone think of anything that might have happened from 2007 to 2009 that would have reduced our carbon footprint by about 8%?

So what are we left with? When you include the boats and planes that refuel in the UK and allow for the recession we've just been having, well then you're left with about a 17% saving over 19 years, or about 0.9% per annum. Somehow that doesn't seem so exciting to me.



Here is the data table as published under, I believe, Kyoto reporting agreements. You'll notice it doesn't include shipping and aviation, we had to dig those out of a footnote to come up with the chart above.
