Membership at Level 5 builds on Level 4, but the hotel would also have ISO and/or other certificates or awards to show that environmental concerns were an intrinsic part of management policy.
There would be detailed policies (available to guests on request) regarding energy saving (in rooms, kitchens, public spaces and in external facilities such as lighting and parking).
The hotel management would show awareness of the environment in all their dealings with guests, staff, suppliers, local authorities and certification authorities, including regular inspections to check on continuing improvements.
There would be an annual sustainability report published on the hotel website, along with the hotel environment charter.
The member of staff in charge of environmental concerns would be a qualified architect or engineer or maintenance expert, able to demonstrate how eco-friendly policies were implemented in the building fabric, lighting, water management, vehicles, food management, waste and other issues.
In the case of new hotels, they must be constructed in the spirit of innovative buildings aiming to be carbon neutral and to sequester carbon emissions.
It is possible to save paper with electronic purchasing software, with suppliers informed of the hotel’s green policy.
There are now many agreements between hotels and suppliers for collection and reuse of packaging.
Cleaning and washing should be with biodegradable / phosphate-free products. Locally sourced building materials should be used in the hotel wherever possible.
