Groupe Eurotunnel, the operator of the Channel Tunnel and Le Shuttle service, has emblazoned the Carbon Trust Standard logo onto its Le Shuttle locomotives. Le Shuttle transports 2.5 million passenger vehicles and 1.4 million lorries each year between England and France.

The company has held the Carbon Trust Standard since 2009 for all of its operations, including the Channel Tunnel and all its railway subsidiaries: GB Railfreight, Europorte France, Europorte Proximite, Eurotunnel Channel, Europorte Services, and Socorail.

Eurotunnel continues reducing its emissions through a number of initiatives, such as reducing the speed of trains using the Tunnel at night, using less energy for cooling the Tunnel, and sourcing its electricity supply from low-carbon sources based in France.
