Thanks to this Forum community for sharing information on purchasing a carbon offset for your travel. Our flights to Europe burn a lot of Jet Fuel (Kerosene)!
I have gone from backpacking through Europe using Rick's tour books from the library to now being a little older and enjoying my first Rick Steves tour. For my first tour - The Best of Eastern Europe, 14 days - I decided that now was the time to also start offsetting the carbon pollution that my trips generate. (flight and transportation)
So, I shopped around a bit for a carbon offset and here is what I found.
The top three companies seemed to be:
1-Carbonfund
2-Terrapass
3-NativeEnergy
And you may also be able to buy them directly from your airlines.
I used an online carbon calculator to determine that my own flight to Prague from the East Coast of the USA and back is estimated to generate more than 17,000 lbs of CO2. Then I rounded up my estimated total carbon up to 20,000 lbs CO2 to also account for the impact of the tour bus travel for 7 days (+ 2,500 ibs). Based on recommendations from several friends, I used Terrapass to purchase a Personal Carbon Offset for 20,000 lbs at a cost of $99.80.
I am looking forward to my trip, and I am wondering if any other travelers have an experience with this matter. For more information on this process click here - http://www.wikihow.com/Buy-a-Carbon-Offset
