FLY, BUT WITH IMAGINATIONAvoiding one single flight = 39 treesFlying is beautiful, but the wings have a high environmental cost. A 1.400km (870 miles) roundtrip flight involves the emission of nearly 400kg of CO2 , equivalent to the amount of CO2 that can be absorbed by 39 trees in a year. The plane is the means with greater CO2 emissions, especially over short and medium distances where takeoff and landing weight is greater. Flying is the way of moving with biggest CO2 emissions, and, according to some studies, CO2 emission at altitudes have a much bigger greenhouse effect then the ones made at sea level. For this reason we should fly only when strictly necessary and when the distance to cover is very high. For work we can rely more on technology, which allows us to make effective meetings with people at a considerable distance. Video conferencing let you see in people’s faces and to connect effectively people around the globe. When you travel for pleasure or for tourism, however it’s important to wonder about what you look for in a trip and see if you can find it in a closer destinations, reachable even without plane. Car, not only train, in this case is a valid alternative. For leisure generally it’s quite usual you move not alone, and so if you share a car you dramatically reduce your impact and your CO2 emissions. While on the plane you can not share your seat.
