Eurostar won the Train Operator of the Year award in the HSBC Rail Awards for 2005.[1] In 2006, Eurostar's Environment Group was set up,[151] with the aim of making changes in the Eurostar services' daily running to decrease negative environmental impact.[152] The organization set itself a target of reducing carbon emissions per passenger journey by 25% by 2012.[152] Drivers were trained in techniques to achieve maximum energy efficiency, and lighting was minimised; the provider of the bulk of the energy for the Channel Tunnel was switched to nuclear power stations in France.[152] Eurostar's target was to reduce emissions by 35 percent per passenger journey by 2012, putting itself beyond the efforts of other railway companies in this field and thereby winning the 2007 Network Rail Efficiency Award.[151] In the grand opening ceremony of St Pancras International, one of the Eurostar trains was given the name 'Tread Lightly', said to symbolise their smaller impact on the environment compared to planes.[153] By 2008, Eurostar's environmental credentials had become highly developed and promoted.[154]
