InterContinental Hotels Group (IHG) plans to launch Innovation Hotels, a green standard for all IHG brands.
The hotel chain plans to convert all of its brands to being so-called Innovation Hotels within the next few years.
As Innovation Hotels, each hotel will feature solar panels on its roof as well as a rooftop garden to provide extra insulation.
The new standard will also feature recycled glass windows, furniture made from recycled materials and a rainwater harvesting system for toilets.
