Virtual arrival: Implementation of virtual arrival can reduce GHG emissions on the tanker and bulk carrier sectors by 5% (BP, 2010). Slow steaming: Maersk Line's experience in slow steaming shows that for over 1½ year since its implementation in 2009, the relative CO2 emissions were reduced by 7% (Maersk Line, 2010). Hanjin Shipping experience: With a number of efficiency measures put in place (Hanjin, 2010), the overall emissions of the company's shipping sector in 2010 were reduced by 12% (expressed in g-CO2/teu-km) compared to 2008 levels.
