In 2007, Eurostar became the world's first carbon-neutral train service through its launch of “Tread Lightly,” an environmental program with the goal of reducing the trainline's carbon dioxide emissions by 25% by 2012.[166][167] The program included: reducing power consumption on its rolling stock; sourcing more electricity from lower-emission generators; adding new controls on lighting, heating, and air conditioning; reducing paper usage via electronic tickets; recycling water and employee uniforms; sourcing all food on board from Britain, France, or Belgium.[167] Eurostar also funded three renewable energy projects in developing regions around the world: a windfarm in Tamil Nadu, India; a micro-hydropower project in China; a plan specifying improvements on fuel consumption of three-wheeler taxis in Indonesia.[166]
