Flight shaming is becoming a thing.
If you didn't know, "Flight Shaming" tries to discourage people from flying, citing concerns over the impact to the environment.
In a recent report, Swiss bank UBS said the social pressure to discourage frivolous flights could cut passenger traffic in half.
In a summertime poll, 20% of the 6,000 people questioned said they cut air travel by at least one flight because of climate concerns.
The Air Transport Action Group says commercial flying accounts for about 2% of global carbon emissions and about 12% of emissions from transport.
Reuters reports: "With the pace of the climate change debate, we think it is fair to assume that these trends are likely to continue in developed markets," wrote UBS analyst Celine Fornaro.
UBS said it expects the number of flights in the European Union will increase by just 1.5% per year, which is half the rate predicted by plane maker Airbus.
Any cut in air travel will hit air manufacturers hard, with new plane orders at risk if travelers increasingly turn to trains and boats to travel with a cleaner conscience.
