Air New Zealand is now offering carbon offsets on its flights. The first question with any offset scheme is whether the offsets are robust, but in this case they're using Emissions Reduction Units from Trustpower's Tararua windfarm - actual Kyoto AAU, so they're rock solid environmentally.
The question now is how many people will do it. However, one obvious customer will be government departments, which now have to pursue carbon neutrality. And I think they'll be quite happy to pay the extra five bucks a ticket to do so.
