WORLD’S LONGEST UNDERSEA TUNNEL STAYS COOL AND REDUCES ENVIRONMENTAL IMPACT.(EUROTUNNEL)

Eurotunnel’s sustainability efforts boosted with completion of new cooling system in
landmark Channel Tunnel that delivers energy savings of at least 33 percent or 4.8GWh per year

Eurotunnel today released official data demonstrating energy savings of 33 percent after the
first season of operating a new cooling system for maintaining requisite temperatures in the
landmark Channel Tunnel. The operator saved 4.8 GWh and approximately €500,000 in 2017
courtesy of the new cooling system – equivalent to saving enough electricity to run 1,000
households.
The newly-released data from the operation of the new cooling system will dramatically boost
Eurotunnel’s sustainability efforts, which, to date have been recognised with its fifth
consecutive certification from the UK’s Carbon Trust Standard for a further 9 percent
decrease of its carbon footprint in 2015-2016 compared to 2012-2013.

François Gauthey, Deputy Chief Executive Officer of Getlink, Channel Tunnel owner, said:

“Eurotunnel’s commitment to environmental protection involves a number of initiatives. We  saw the replacement of the Channel Tunnel cooling system as a chance to reduce our energy consumption and carbon footprint. “This effort required installing a new cooling
system—Europe’s largest—to maintain the Channel Tunnel at optimal ambient temperatures.
Honeywell’s Solstice® zd refrigerant, with its ultra-low global warming potential (GWP), and Trane’s chillers, which are already being used to cool large buildings and infrastructure,provided the best combination of features to help us meet our energy and environmental goals.”
