I've never used it myself, because I don't feel like it should be up to the passenger/user to volunteer to pay for their carbon. I also donate to charities outside of carbon credits, and those donations are tax deductible, unlike carbon credits. I'd be more inclined to buy carbon credits for my travel if they were tax deductible like charitable donations are.
