CO2 emissions are only part of the story when it comes to the effects of aviation on the climate [1]. For example, contrails and formation of clouds contribute to warming. Additionally, the proportion of emissions attributable to flight is expected to grow significantly over the next 30 years. And it's easy to understand why, a single roundtrip flight across the atlantic is comparable to a whole year of commuting [2].
