This morning, ClimateBiz reports on a recent survey by a Seattle P-I journalist on carbon calculators. The reporter tried out ten different calculators, and here are the results:
Not surprising. Last year, I did my own exploration of carbon calculators, and came out equally confused. TerraPass had made it into my list of Top 3 Calculators, along with ZeroFootprint and Nature. Now comes Cool Climate, the new calculator from UC Berkeley, that promises to be better than all its predecessors.
Not only is it hard to figure out which calculator to use, but there is also the accountability problem of carbon offsets, carbon calculators’ close cousins. When I am sitting at home in California, how can I know for sure, that the money I am giving will indeed result in carbon credits? The alleged 20% rate of doubtful credits, as reported by the U.N. Clean Development Mechanism organization, spells out caution.
Last, I have my own reservations about the behavioral consequences of relying too much on carbon offsets. I have said it before, we cannot buy our way out of our predicament. Conservation, efficiency, smarter technology solutions, should always come first, with carbon offsets as the absolute last resort. Recognizing that there are indeed circumstances when one has to fly, as an example, and carbon offsets do have a very legitimate role.
I wonder, what is your experience with carbon calculators? Do you buy carbon offsets? If so, when? How would you improve the current system?
