So much hot air...

Spurred on by others' green credentials and guilt about how much CO₂ my flying to New Zealand (and back) dumped into the atmosphere, I had a go on the Carbon Calculator website. If you put in details of where you've been and how you got there, it will tell you how much pollution you caused. I think even by walking to the kitchen you can destroy a sizeable section of the ozone layer. I'm staying on the sofa.

The upshot is that flying half way round the world and then coming back covers 38 572km and produces 4.2 tonnes (metric with an "...nes" on the end) of carbon dioxide...



...but it's not the end of the world (either literally or metaphorically) because I can buy trees to the value of £31.08, almost a forest, and everything will be OK and I will sleep at night. (If I'd only been to New York I would've got away with a measly £8.88 worth of trees. Which is a small tree in Durham somewhere.)

And I was actually going to do it!

But it seems trees are out of stock at the moment...



You see, this is what you get when you try to be holier-than-thou. If there are no trees left to buy, then there's probably something more wrong with the world than my £31.08 will put right...
