  No green here

  More Gore lore

  I still like the opening line he used for his speeches a few years ago: "My name is Al Gore, and I used to be the next President of the United States."On Gore's impromptu humor at a recent small climate summit posted 1 year, 9 months ago 14 Responses

  Great analysis

  An informative and insightful (and even fun, in a satisfyingly snarky way) read.  Thanks!On 'Environmentalists say' the WaPo should learn to distinguish rhetoric from reality posted 1 year, 10 months ago 2 Responses

  A Few Comments

  Kudos to Clark Williams-Derry for the helpful post examining what's behind carbon offsetters' air travel calculators.  It's great to see this information gathered in one place, even if the only definite conclusion that can be drawn is it's complicated. :)

  I noticed the chart from the Stockholm Environment Institute says, "Calculations were done on 7/3/06 if not indicated otherwise."  A year and a half is a long time, especially in a quickly-moving industry like carbon offsets.  Carbonfund.org has been using an updated calculator for some time.  It includes, among other improvements, a multiplier for radiative forcing and the ability to choose departure and arrival locations.  

  You can read about the methodology for the air travel calculator and all the Carbonfund.org calculators here: http://www.carbonfund.org/site/pages/carbon_calculators/c ....

  Thanks for this great post and keep up the good work.  Transparency is the name of the game for carbon offsetters, and we applaud any effort to increase it.  To that end, we'll be featuring a posting on the Carbonfund.org blog in the near future detailing the decisions behind our assumptions for air travel.
