Energy supplier npower is the latest company to be awarded a ‘green’ standard for its efforts in reducing carbon emissions.

Launched in June 2008, the Carbon Trust Standard, which verifies the carbon footprint and emission reductions of organisations, was awarded to npower for measuring, managing and reducing its greenhouse gas emissions.

Npower claims it also achieved a 16% decrease in electricity usage last year, putting it on track to meet its 2014 target of a 38% cut in carbon intensity of its offices compared to 2008 levels. The savings are believed to have been made through lighting upgrades, heating and ventilation systems and monitoring and minimising energy use.

Darran Messem, Managing Director of Certification at The Carbon Trust said: “Energy suppliers have a big role to play in promoting energy efficiency and helping customers to reduce their carbon footprints. By putting sustainability at the heart of its own buildings, npower is leading by example when it comes to using energy as efficiently as possible.”

Paul Massara, CEO of npower added: “The certification demonstrates that big energy efficiencies can be made when you have the right tools for the job. The carbon reductions we’ve made can be achieved by other businesses on their own sustainability journeys.”

More than 650 organisations have achieved the Carbon Trust Standard since its launch, collectively cutting their emissions by more than 4.3 million tonnes and cutting gas, electricity and fuel costs by £645 million.
