Largely due to its combined natural and cultural attractiveness, Europe is the world's primary tourism destination and tourism generates 10% of EU GDP. New types of tourism and increased frequency of holidays have serious environmental impacts at regional and local level. A damaged environment could undermine tourism in the future.
Responses to sustainability challenges are dispersed across EU legislation and policies, while the evidence base to track progress is still fragmented.
Europe is the world's number one tourist destination. In 2013, France, Spain, Italy, the United Kingdom and Germany were among the world's top 10 destinations for holidaymakers. As a result, in 2010, this industry became a key sector of the European economy, generating over 10% of EU GDP. Thus tourism also contributes to regional and potentially sustainable development, while shaping a European identity and awareness on natural and cultural heritage.
The European Union (EU) aims to promote tourism in order to maintain the region's position as a leading destination, and maximise the industry's contribution to growth and employment. The 2010 European Commission communication, 'Europe, the world's No 1 tourist destination — a new political framework for tourism in Europe', is the most recent general policy reference and establishes main priority actions for the sector.
Figure 1: Components of the tourism system
The tourism industry is composed of many different sectors, including transport, agriculture, and energy (Figure 1). Because of this, policy responses to the sustainability challenges are fragmented across large areas of EU legislation. A comprehensive policy reference specifically for tourism does not yet exist.
This policy fragmentation leads to problems of data availability for the sector as a whole, especially with regard to environmental impacts. As a result, the European Commission encourages a coordinated approach for EU initiatives in order to consolidate the whole knowledge base (such as through the European Tourism Indicators system) and to increase sustainable growth (as recalled in the European Commission communication, 'A European Strategy for more Growth and Jobs in Coastal and Maritime Tourism').
Peak periods have traditionally led to high environmental pressures especially in islands, coastal and mountain regions, while new trends are constantly emerging, with tourism taking place throughout the year, during the off-season, or in some cities that experience consistently high levels of visitors. This is due to globalised trends in culture and communication, an internet‐based economy, and the increasing affordability of travel for ever-larger sections of the population. Europe has also become the world's largest 'source region' of tourists taking trips elsewhere in the world.
Key trends in tourism volume (demand and supply) and intensity at country level
In 2012, within the EU-28, 51.3% of the population made at least one trip of four overnight stays during the year as a tourist.
More than half (57.4%) of the nearly 545 000 accommodation establishments active in 2012 were concentrated in four EU Member States: Italy, Spain, Germany and the United Kingdom.
In 2012, Spain was the most common tourism destination for non-residents, followed by Italy and France, which together accounted for 48.7% of the total nights; this needs to be seen in connection with the rapid growth in secondary homes (Box 1). As for tourism intensity in 2012, the Mediterranean destinations of Malta, Cyprus and Croatia, as well as various destinations within Austria were the most popular.
Key trends in tourism density demand and intensity across EU regions
Tourism intensity within a certain destination shows the huge importance of tourism to many of the EU's coastal regions and, even more so, to its islands and most of the Alpine region. In the context of the sustainability of tourism, this relationship can also be seen as an indicator of potential tourism pressure in the 20 top regions that together accounted for 38.6% of the total overnight stays in 2011.
Also tourism density is particularly concentrated in coastal, mountain, and lake areas, where an increase in building and infrastructure has increased environmental pressure on protected and other natural and semi-natural territories.
Especially in the Mediterranean, tourism infrastructures and activities often have irreversible effects on natural areas rich in biodiversity and results in habitat deterioration for both terrestrial and aquatic plant and animal communities.
Tourism impacts on environment and health
Despite the difficulties of quantifying the real impact of tourism on the environment, any increase in the number of tourists undoubtedly has an impact on environmental variables such as waste generation and energy consumption (in terms of volume and local level).
A tourist consumes 3 or 4 times more water per day than a permanent resident, with non-tourist water use ranging between 100 and 200 litres per person per day across Europe. Necessary investments in the sewage system and wastewater treatment have taken place and have led to Europe's bathing waters being much cleaner today than they were 30 years ago. In 2013 more than 90% of bathing areas were judged as having good water quality.
In Torremolinos (Spain), electricity consumption (of which tourism accounts for about 40%) increased by 160% between 1989 and 2008, while several studies have reported increases in municipal solid waste (MSW) as the seasonal tourist population rises. This has particularly been the case in small islands which are environmentally more vulnerable to the MSW growth and where any negative effects on health may spread more quickly. In Menorca, during the period 1998 to 2010, the daily average of MSW generated in August by tourists is higher than that from residents, while a Maltese resident generates a daily average of 0.68 kg of MSW compared to a daily average 1.25 kg by a tourist in a hotel.
Tourist transport by car causes the largest impacts on air quality whereas air transport accounts for the largest share of tourism-related GHG emissions (80% in 2000) in the EU-25. Rail, coaches and ferries account for almost 20% of all tourism trips, but are responsible for a very small percentage of environmental impacts. The most emission-intense mode of transport per kilometre travelled is cruise ship: direct air emissions of 0.330 kg CO2 per ALB KM have been estimated. Furthermore, most cruises start with flights to reach harbours, adding between 10% and 30% to the total emissions caused by the cruise.
The increasing speed and scale of global human movement has also enhanced opportunities for the spread of disease. In 2011, Europe was the main source of importation for measles into the USA, while several mosquito-transmitted diseases have expanded their range and locally occurred in northern Italy in 2007 and southeast France in 2010.
Response and prospects
Recent EU surveys show that the predominant factors in choosing holidays destinations continue to be the quality of natural features and landscape, especially in coastal areas. That confirms the importance of 'natural capital' for the health of the tourism sector that is becoming more environmentally conscious due to actions, some external, such as progressive policies, fiscal measures, and the highest number of 'green' certification schemes in the world (such as eco-labelling). However, many of these certification schemes are still showing limited effectiveness in terms of cost savings or increased consumers demand. More coherence should be provided across them, while also improving consumer confidence.
By 2020 the car is still expected to account for the largest share of trips by tourists, while air travel will account for the largest share of kilometres travelled compared to today. Europe will also continue to lead the world in international arrivals, which are expected to increase from 57 per 100 of the population to 89 per 100 in 2010–2030. Globally, air passenger/km are expected to rise from 5 billion to more than 13 billion over the period 2010 to 2030, while intra-Europe travel is projected to remain among the world's top five travel patterns between 2030 and 2040.
Box 1: Environmental impacts from second homes
Rapid growth of second homes during the 1990s increased pressure on the environment, especially in coastal and mountain zones. This caused negative impacts such as land uptake, transportation to and from the homes, wildlife disruption, disposal of human waste and visual pollution.
High densities of second homes can increase competition between their owners and locals for shared natural resources, resulting in huge pressures on infrastructures such as water supply, sewage, and roads.
However, second homes made out of renovated rural stocks, instead of large scale tourism development, may also positively contribute to local communities.
In Europe many second homes are owned by people resident in other countries. For example, the breakdown of the location of second homes owned abroad by residents of the United Kingdom is 27% in Spain, 26% in France and 23% in the rest of Europe.
Efforts exist to regulate construction of second homes. In Switzerland, with some exceptions, the construction of second homes is banned in areas where they already account for more than 20% of all homes.

 Actions: stimulate competitiveness in the European tourism sector; promote development of sustainable, responsible, high-quality tourism; consolidate Europe's image as a collection of sustainable, high-quality destinations; maximize the potential of EU financial policies for developing tourism.
 These challenges mainly concern: 1) energy consumption and supply, water quality, consumption and management, 2) waste production and management, 3) loss of biodiversity from land conversion, over-exploitation of natural resources or introduction of invasive alien species, pollution and disturbance of wildlife, 4) landscape and heritage management.

 In 2011, people aged over 65 made 29% more trips and 23% more overnight stays than 2006. Their tourism expenditure grew by 33% and accounted for 20% of all tourism spending of Europeans, compared with just 15% in 2006. They made more and longer trips. This group of tourists is expected to grow fast as in 2010, 17% of the population was 65 years old or more and by 2060, this figure is expected to be close to 30%.

 Like those ones caused by the Chikungunya virus. The Chikungunya virus was largely restricted to Africa and Asia until it began to appear on islands in the Indian Ocean in 2005, after an outbreak in Kenya in 2004. From there, it crossed to the Indian subcontinent in 2006, causing outbreaks of major diseases, especially in southern India.
