An employee who works British Airways (BA) has told newspapers the company creating more CO2. The unnamed person is a whistleblower - someone who tells the truth company secrets. The whistleblower said BA and many other airlines use "fuel-tankering" to save money. However, fuel-tankering is very bad the environment. Scientists say it adds to global warming. Fuel-tankering is when airplanes store extra fuel to get to their destination and back. This means the airline saves money paying all the fuel its home country instead buying more expensive fuel its destination. Scientists say fuel-tankering puts as much CO2 the air each year as a large town.
A documentary British Airways and fuel-tankering was shown the BBC this week. In the documentary, the CEO BA promised to look again how it carries fuel. He said the airline uses the fuel-tankering method and said it was "maybe the wrong thing to do". The money saved fuel-tankering each flight is very small, but there is a big cost to the environment. A recent flight London to Italy had three tons extra fuel. The airline saved just $50 on the flight but an extra 600kg of CO2 was put the atmosphere. Greenpeace said this was a "classic example a company putting profit before planet". It said: "They'll happily pour extra fuel the fire a small boost to their profit margin."
