Water cooler company Eden Springs claims it has slashed its carbon emissions by 184,000 tonnes since 2010.
The water and coffee supplier reckons it has offset the same amount of carbon as nearly 378,000 flights from London to New York by working with The Carbon Neutral Company.
Giving customers water coolers that turn off during the night and on the weekends is partly to thank for the results.
Transportation and biodegradable products also helped, while it now uses five gallon water bottles 50 times before they are recycled. The company says it is looking into greener transportation.
Chief Executive Raanan Zilberman said its office customers “can be reassured not only of a high quality experience for their employees and clients but also that they are contributing positively to their own environmental and social responsibilities”.
