I have been trying to find a good site/company to offset my flying however I haven't found any that matches my criteria: Easy to input the trip that should be compensated. Ie. I want to be able to write HEL-CPH-CDG-ATL-etc.. and not have to select each segment individually. The company should not be some half bogus one but the payment must be used without much deduction for administration etc. Some kind of certification would be good. Can anyone please help me find such a site to compensate my pollution?
