LED light bulbs are set to replace traditional lighting in more than 300 hotels after the owner of accommodation chains Radisson, Radisson Blu and Missoni kicked its sustainability plan up a gear.

Rezidor hotel group will look to save 25 per cent on its current energy consumption by 2016, which is expected to deliver a saving of €25 million (£22.2 million) over the next four years.

Having signed a contract with Philips Lighting, the hotelier can move onto the next stage of its ThinkPlanet sustainability programme.

"One of the things we're going to do across the board is the move to LED lighting in all our public areas by the end of 2013," explained Inge Huijbrechts, director of responsible business at Rezidor, to BusinessGreen.

"Philips will provide technical assistance and design assistance for the different hotels because it's very important to choose the right lighting and take into account aspects like dimming and transformers, etc."

It is not the first time the hotel company has made its green intentions clear, having already declared in 2011 that all its new and refurbished hotel rooms would carry LED signage and equipping 94 per cent of all hotels rooms across its portfolio with energy efficient bulbs.

Newer technology like motion sensors and daylight sensors will also be fitted to its hotels in order to use illumination only when necessary, and the group will be monitoring their eco-friendly progress with monthly reports on a number of key performance indicators.

Speaking at the launch of Rezidor's green campaign, Ms Huijbrechts commented: "Think Planet reinforces Rezidor's position as one of the industry leaders in terms of sustainability. Many of our hotels have already introduced progressive, environmentally friendly measures - now we are spreading these initiatives into all our properties and focus on key energy-saving investments that will have the biggest impact."

The latest news follows a collaboration between the International Tourism Partnership (ITP) and the World Travel and Tourism Council (WTTC), along with a number of global hospitality companies, to come up with a way of measuring the carbon footprint of every guest's hotel visit and meetings.
