When choosing flights for travel, there are a few things you can do to minimize your environmental impact. One thing is to choose nonstop flights; multiple flights with connections or layovers contribute more air pollution. But here’s one you may not have heard of: Avoid red-eye or nighttime flights. The pollution emitted from planes at night has a more detrimental impact on the environment. Scientists have found that CO2 emissions at night aren’t offset by their “tendency to reflect incoming sunlight,” so they are basically twice as bad for the atmosphere.
