The political agenda is manifested in policy as well as legislation. Policies relating to environmental conservation and sustainable development provide an example of how policy can influence developments in tourism. since the 1980s, international strategies, conventions, resultant national policy and growing public awareness have ensured that the concepts of sustainable development and eco-ethics have penetrated all types of business and activity . However, because sustainable development is more of a policy matter then a legislative one, some companies and authorities take it board more then others. This is as true of the tourism industry as any other.
