Energy-saving measures often relate mostly to technological improvements and renewable energy investments. However, the T2K partners believe that raising staff awareness on energy and carbon issues must be placed at the heart of any carbon strategy. Changing the behaviour of internal staff is crucial, as their daily actions will directly impact energy use in buildings or vehicles. An energy-efficient investment will not reach its potential if the people in charge of the system are not aware of its aim and proper functioning. Besides raising awareness, public transport operators should improve their staff ’s technical knowledge through training.
