The answer, of course, is very little.

 The Lisbon Treaty acknowledges the importance of tourism outlining, for the first time, a specific competence for the European Union in this field and allowing for decisions to be taken by qualified majority (Title XXII Tourism, Art. 195)

From The European Commissions DECLARATION OF MADRID WITHIN THE SCOPE OF THE INFORMAL MINISTERIAL MEETING FOR TOURISM UNDER THE SPANISH PRESIDENCY IN APRIL 2010 IN MADRID UNDER THE MOTTO "TOWARDS A SOCIALLY RESPONSIBLE TOURISM MODEL"

Doesn't it make you wonder why we  bother to have a parliamentary election in the UK, when even tourism is controlled by our real government in Brussels.

Also from the document

The raising of public awareness and promotion of responsible attitudes of European tourists is also essential in order to increase the demand for responsible tourist products and services in Europe.

This begs the questions. 1. What is a responsible tourist?

2. Isn't there a suggestion here that some action must be taken against the irresponsible tourist?

and from page 3.

3. Facilitating the access to holidays to groups with impaired mobility or those who are socially and/or economically disadvantaged, promoting as the same time a better and more prolonged use of tourist infrastructures, the maintenance of tourist activity in the regions for longer periods, and a strengthening of the feeling of European citizenship

Hmmm - holidays become a right for some, for the taxpayer to support?

pge 4.

 The Member States declare their willingness:

4. To support measures and initiatives encouraging the lengthening of the high season in tourism, thus contributing to reduce seasonality and to maintain tourist employment in off-season.

If this wasn't from the EU's website, I would have thought that it was some sort of strange joke.
