In an effort to reduce confusion about what constitutes sustainable tourism, media tycoon Ted Turner announced this morning that a set of specific criteria has been developed under the auspices of the United Nations Foundation.

The coalition, called the Global Partnership for Sustainable Tourism Criteria, received input from 2,500 conservationists, industry leaders, governmental authorities and U.N. bodies, Turner said. The resulting criteria focus on four aspects of sustainability: maximizing tourism’s social and economic benefits to local communities, reducing negative impacts on cultural heritage, reducing harm to local environments and planning for sustainability.

The 40 specific points within the criteria range from respecting the intellectual property rights of local communities to measuring greenhouse gas emissions and implementing procedures to reduce and offset them. To see the complete list of criteria, click here.
