I attended a presentation today on Carbon Offset for vacation travel. Expedia offers TerraPass carbon offsets already, as do several of the major rental car companies (view full list).
In case you are scratching your head wondering in the world a Carbon Offset is...
What is a Carbon Offset? (From TerraPass)
A carbon offset is a certificate representing the reduction of one metric ton (2,205 lbs) of carbon dioxide emissions, the principal cause of global warming.
I am interested if any of you have purchased carbon offsets as a part of one of your vacations. If so, what drove you to purchase them? Generally speaking, what do you think of this idea?
