Airports use a good deal of water and produce a fair amount of waste. At Heathrow International Airport in London, environmental responsibility is taken seriously.
"At Heathrow, we are committed to managing water sustainably by sourcing it responsibly, controlling use and efficiency, carefully managing the disposal of water, and monitoring our impacts on the surrounding environment."
In fact, from 2012 to 2013 Heathrow achieved a 3% reduction in water consumption per passenger
