Sustainable tourism: In 2016 Spain was the third most visited country in the world with 75.3 million tourists. This is great for the economy and job creation but what is the impact on the environment? Besides CO2 emissions from transportation by plane and car, the biggest environmental impact is from water usage and plastic waste.
Because of the hot climate and the tendency of tourists to consume more water when on holiday than they do at home, the amount used can run up to 440 liters a day. This is more than double what the inhabitants of an average Spanish city use and has a major impact on the areas with water shortage in Spain.
In addition to this, tourists generate a lot of waste and in particular plastic waste. 75.3m tourists with an average stay of 5 days consuming 2-3 plastic water bottles per day each is about 940m bottles or 28.2km2 (the equivalent of 1/3 of the city of Barcelona) covered in plastic. And that is just water bottles. Other plastic packages such as soda, juices, sun creams and hair products add up to a similar amount. (Source: Eurostat)
