Sacha's mum (that's what they have in the jolly old), one Maureen Haworth, sent her this article, which made its way to me via the emails (does anyone else long for the day of pneumatics?).
To be clear, I'm not opposed to trading your pollution credits (it seems like a natural extension of the market...highly inevitable...and vital if the whole thing is to work...but that's a whole other story). What I'm opposed to that this article pokes fun at so well is (a) the self-aggrandizing nature of this, and the marketing initiatives that are sure to follow, that only feed into our culture of selfishness and (b) trading pollution credits while you zip around in your Hummer (the last line of the article sums it up nicely).
Anyway, thanks Mrs. Haworth, wherever you are.
