Took a few minutes and used an emissions calculator to work out that my air travel from 2003 to the present caused the emission of approximately 24 tonnes of CO2. Spent a few more browsing from
http://www.ecobusinesslinks.com/carbon_offset_wind... to see what my options for offsetting are. I'm not terribly enthused about any of the schemes based on retiring pollution credits or whatever from emissions trading schemes - emissions trading between companies seems perfectly defensible but me paying a company to save energy strikes me as less obviously a good thing, partly because it ought to have benefits in and of itself so why should I pay them to do it and partly because it strikes me as potentially undermining an emissions trading scheme for me to reduce the supply of credits tradeable between companies by buying some of them myself. Taking the argument to absurd lengths, if too many people did it and bought up the whole supply, where would unavoidably polluting industries buy their credits? Of course, this ought to raise the price of credits and thereby encourage more supply. And raise the incentive for companies to lower their own emissions rather than buy credits. Although I find that a bit dubious as long as we're talking about voluntary trading schemes. In any case, I'm not so enthused about subsidising a company to reduce it's emissions - would much rather see a mandatory cap and trade scheme, absent the even better solution of a carbon tax . In any case, of the projects I looked at, the Solar Electric Light Fund (rural electrification projects in the developing world to substitute for kerosene and diesel) seemed the most appealing theoretically. I wonder whether I should be disturbed at the lack of independent certification but it seems likely it may simply not exist for this sort of project.
