The owner of premium drinks like Johnnie Walker, Baileys, Captain Morgan and Guinness has made the switch to using 100% of its electricity from renewables at its Norwalk headquarters in the US.

The alcoholic drinks giant’s Norwalk office joins three of the company’s other sites in using 100% energy from renewable sources.

This, it claims, means 50% of electricity being used globally by Diageo are now coming from low carbon sources.

Larry Schwartz, Diageo’s North America President said: “By purchasing electricity derived from renewable sources, like wind or solar power, we will reduce our carbon emissions in Norwalk by more than 92%. This transition is just one of many positive changes Diageo has made in the last five years to deliver significant and sustainable improvements on our environmental impact.”

The company also generates its own renewable energy at its production sites and purchases carbon offsets for its fleet of commercial vehicles. Diageo claims the Norwalk facility has also earned an ‘Energy Star’ from the USA Environmental Protection Agency.
