EU statistical agency Eurostat has made what it calls a "first tentative attempt" at quantifying tourism's impacts on the environment. The data "suggest a causal link" between tourism density and higher electricity consumption, waste water and municipal waste generation, and drinking water consumption, the brief report concludes. But it does not establish a direct relationship with air pollution, saying it was "too difficult to quantify the real impact". For each clear link between tourism and environmental pressure, the report also finds regions that do not conform.
