Despite a group of green hotel and tourism standards to emerge in the last decade or so, the idea has not proved to be hugely effective in either marketing or reputation protection.  NGOs such as Greenpeace have criticised many such standards/schemes as being superficial and not addressing the key environmental impacts of resorts and hotels, namely energy and water use and land conversion.  In the niche of eco-tourism, standards and schemes remain important as a means of informing their customers (who are by nature environmentally aware and curious) of their credibility.   Perhaps the key issue at present for the hospitality and events sector is carbon emissions and this is the focus of standardization at present.

• Leading standards

The largest number of standards relate to eco-tourism and are mostly specific to location (e.g. Scotland, Italy etc).  Similarly for hotel standards.   In 2009, British Standards Institute launched the world’s first standard specifically related to sustainability in the events sector, BS 8901.  Many BS standards have formed the basis for international (mainly ISO) standards and the ISO events standard has nominally been termed ISO 20121. The COP15 Climate Change meeting in Copenhagen has become the highest profile environmental meeting to gain certification to BS 8901. A much larger and complex event which is aiming for BS 8901 certification is the London Olympic Games in 2012.  In February 2009, the London Organizing Committee for the Olympic Games (LOCOG) published its sustainability guidelines for all opening and closing ceremonies and the games themselves.
