A year and a half ago American Airlines CEO Doug Parker was scoffing at United’s investments in biofuels being good for the environment. There was real evidence for his position, that current biofuel technology is simply too resource-intensive to be useful.

Now, though, American has done a 180 – with a new President whose environmental priorities open up the possibility for new subsidies.

United Airlines has announced that they’ll reduce greenhouse gas emissions 100% by 2050, making a bolder claim than world airlines through trade association IATA which commit to a 50% reduction in carbon footprint by 2050.

Adding United and perhaps soon others could help bring about critical mass that makes this technology viable to solve our environmental problems.

Noble goals, and surely they’ll make progress towards those goals, but the claim that they’ll be a carbon neutral airline next month is dubious to say the least.

Several airlines sell Catholic indulgences that go by the name carbon offsets. The idea is that they’ll funnel donations to non-profits that do good for the environment in some amount the counteract the effects of carbon attributable (on average) to a given passenger’s travel.

I’m skeptical of these measures for several reasons. Not least of which because adoption rates are infinitesimally low.
