Air transport account for less than 4% of the 51 b tons of CO2 we send every year. These politicians aren’t going to make any difference.
We could ask them to be role models, but with what finality? Again air transport is not the most urgent problem. I understand this is a topic that can be used to raise awareness, but the most useful thing these politicians could do is to rethink the way (EU) businesses are leading China and India to use coal for energy. Why no one proposes to handle this topic, I do not understand. And if someone would handle it, then it would be time to use your next vote wisely.
