Sokos Hotels has been granted a Green Key eco-label for all its hotels

Sokos Hotels has been granted a Green Key environmental certificate for all the chain's hotels. Ecological modes of transport and solar panels on hotel roofs are examples of our multifaceted environmental work.

"Environmental work at Sokos Hotels has been persistent, versatile and systematic. Each hotel has found a suitable angle to environmental work that is closest to their heart," says Program Director Marketta Viljasaari from Green Key. "And with the volume of a large hotel chain, small everyday acts yield large environmental benefits," Viljasaari says.

Kick scooters and snowshoes for customer use

An important part of Green Key work is to guide clients in ecological tourism. "We encourage our customers to use environmentally friendly modes of transport, for example. Guests of all our hotels can borrow ecological modes of transport from bicycles to kick scooters and from snowshoes to skis.  Additionally, we offer skiing track, route and city maps to our guests. Customers driving electric vehicles can more and more often charge their vehicles at Sokos Hotels' charging points," says Janina Nurmela, Concept Manager of Sokos Hotels.

The staff is also encouraged to exercise with, for example, stair-stepping challenges and by encouraging the use of bicycles on commutes.

One of the forerunners of the chain and the entire Finnish hotel field is Solo Sokos Hotel Lahden Seurahuone, where solar panels were fitted on the hotel roof in 2014. On a sunny summer, the hotel's entire hot water supply is heated with the energy provided by the solar panels.

Among all the Green Key hotels, this hotel produces heat with solar panels most extensively.

The energy of solar panels can also be distributed for floor heating or heat emitters, which ensures that the energy produced by the solar panels will not be wasted.

Development work for the environment will continue. At the turn of the year, a heat recovery system for waste water was commissioned. Its yield is then times that of the solar panels.

"We are very proud that we have managed to achieve Green Key eco-label for all our hotels in just four years. And our work will not stop here. Our next concrete goal is to decrease food loss by 15 percent by the end of 2020," Nurmela promises.
