A worker said airlines create extra CO2 by fuel-tankering. This is when airplanes have extra fuel to go somewhere and come back. Airlines use "fuel-tankering" to save money. It is bad for the environment. Fuel-tankering creates lots of CO2. It creates as much CO2 each year as a large town.
The boss of British Airways promised to look at this problem. He said fuel-tankering was "maybe the wrong thing to do". A flight from London to Italy puts an extra 600kg of CO2 into the air because of fuel-tankering. The airline saves just $50. Greenpeace said airlines put profit before the planet.
