Although the majority of our environmental impact is associated with jet propulsion, like any large company we also have associated emissions related to electricity, water, waste and ground transportation. In addition to office buildings, we also devote considerable resources on the ground to support the operational requirements of running the airline business in and around the airport, as well as housing more than 20,000 staff in company-provided accommodation. These requirements continue to grow as we expand our flight operations. In 2012-13, more than 4,400 new employees joined the company.
A number of energy and water savings projects are being studied for implementation across the Group's built environment in the coming year.
