Since the 1990s, air flight has made the world a smaller place. In one 24-hour period you can fly to the other end of the globe. In an hour you might be able to skip the traffic and fly to the other end of your country. But this convenience comes at a cost….to the climate. Aviation accounts for somewhere between 2 to 5% of the world’s emissions. And as the world’s desire to travel proves insatiable, the number of planes in the sky each day is only increasing. The aviation industry has aspirational plans to decarbonise using sustainable and/or synthetic aviation fuels. But these are currently some way off. In the meantime, airlines are offering carbon offsets. Offsets are controversial products and only 1% of passengers pay for them. So, this week on The Climate Question we are asking, can flying ever be climate friendly?
