  2. 2. What is the SOER 2010?The European environment — state and outlook 2010 (SOER 2010) is aimed primarily at policymakers,in Europe and beyond, involved with framing and implementing policies that could support environmentalimprovements in Europe. The information also helps European citizens to better understand, care for andimprove Europes environment.The SOER 2010 umbrella includes four key assessments:1. a set of 13 Europe‑wide thematic assessments of key environmental themes;2. an exploratory assessment of global megatrends relevant for the European environment;3. a set of 38 country assessments of the environment in individual European countries;4. a synthesis — an integrated assessment based on the above assessments and other EEA activities.SOER 2010 assessments Thematic Country assessments assessments Understanding SOER 2010 Country profiles climate change — Synthesis — Mitigating National and climate change regional stories Adapting to Common climate change environmental themes Climate change Biodiversity mitigation Land use Land use Nature protection Soil and biodiversity Marine and Waste coastal environment Consumption Assessment of Freshwater and environment global megatrends Material resources Social Air pollution and waste megatrends Water resources: Technological Each of the above quantity and flows megatrends are assessed by each EEA member Economic country (32) and Freshwater quality megatrends EEA cooperating country (6) Environmental Air pollution megatrends Urban environment Political megatrendsAll SOER 2010 outputs are available on the SOER 2010 website: The websitealso provides key facts and messages, summaries in non‑technical language and audio‑visuals, as well asmedia, launch and event information.

  6. 6. Thematic assessment | Consumption and the environment Summary The consumption of goods and services in EEA member countries is a major driver of global resource use — and associated environmental impacts. Growth in global trade is resulting in an increasing share of environmental pressures and impacts from European consumption taking place beyond Europe. Food and drink, housing, mobility and tourism are responsible for a large part of the pressures and impacts caused by consumption in the EU. Achieving significant reductions in environmental pressures and impacts will require changing private and public consumption patterns, to supplement gains achieved through better technology and improved production processes. Drivers and pressures caused by total national consumption can be allocated to eating and drinking, housing and infrastructure, Consumption is shaped by an array of complex, and mobility. These three broad consumption areas are interrelated factors such as demographics, income and estimated to have contributed approximately two-thirds prices, technology, trade, policies and infrastructure, of consumption-related material use, greenhouse gas as well as social, cultural and psychological factors. emissions, acidifying emissions and ozone precursor Production activities across economic sectors, including emissions. extractive industries, agriculture, energy, transport and manufacturing, are directly responsible for the majority The reasons for these high shares are that food and drink, of the environmental impacts caused by the economy. housing and mobility are the areas which Europeans However, it is private and public consumption that are spend most on and at the same time the areas with the the fundamental causal factors and drivers of change in highest pressures per euro spent. Tourism is a fourth area production activities. causing high and growing environmental impacts, both within the EU and elsewhere. Consumption leads to the direct creation of environmental pressures from the use of products and services, for A major reason why consumption negatively affects example, through driving a car or heating a house with the environment and causes an over-use of resources is fossil fuels. Of greater magnitude, however, are the because the costs to society of environmental and resource indirect pressures that are created along the production degradation are not fully reflected in the prices of goods chains of the goods and services consumed, including, for and services. Thus, many goods are relatively cheap example, food, clothing, furniture or electricity.

Never mind the legitimate desires of many other billions on our planet to share those lifestyles .... We will need to change the behaviour of European consumers. To work on peoples awareness, and to influence their habits. Janez Potočnik, European Commissioner for Environment (March 2010) …the major cause of the continued deterioration of the global environment is the unsustainable pattern of consumption and production...

Thematic assessment | Consumption and the environment Box 2.1 Consumption and chemicals There is growing concern about the potential human health and environmental impacts of chemicals in consumer products, in particular persistent and bio-accumulative organic compounds, endocrine-disrupting chemicals and heavy metals used in plastics, lubricants, textiles, cosmetics, dyestuffs, flame retardants, wood preservatives, electronic goods, and food packaging. Exposure to these chemicals is thought to be linked with declining sperm counts, genital malformations, impaired neural development and sexual behaviour, obesity, and cancer. Many of these chemicals leach easily from the products and can be found in the environment — in ambient (urban) air, indoor dust, wastewater, sludge — in some cases at levels high enough to be of health concern (Fisher et al., 2006). Some are highly persistent in the environment where they may undergo further transformation. For example, it has recently been shown that the flame retardant polybrominated diphenyl ethers (PBDE) exposed to wastewater treatment can generate dioxins (Betts, 2009 — orig. Steen et al., 2009). Widely-used plasticisers such as phthalates and bisphenol A; perfluorinated chemicals used in a variety of commercial applications as water, oil, soil and grease repellents; and brominated flame retardants are most often discussed in this context due to their suspected health effects and ubiquitous presence in the environment. A matter of particular concern is exposure to a mixture of low levels of chemical compounds that may exert synergistic effects, especially in unborn and very young, vulnerable children (ULSOP, 2009).representing 268 out of Europes 501 million people more important, for example tourism for degradation(Eurostat, 2010) and allocated them to final consumption of coastal habitats, chemicals in consumer productscategories.

The next set of bars indicate how the pressures would have developed over the same period if they were linked to economic growth only. The two sets of bars can be compared to see if decoupling has occurred. For example, the Netherlands showed strongest decoupling in GHG emissions 1995–2005, while Italy showed very little decoupling. The right-hand two pairs of bars demonstrate the extent to which shifts in consumption patterns and improvements in eco- efficiency in the provision of goods and services have contributed to the observed decoupling.

Box 2.2 Health impacts of unsustainable consumption patterns: obesity Current consumption patterns of a large part of the European population, especially in terms of food and mobility, are linked to several health risks, with overweight and obesity issues being of greatest concern because they are linked to serious health problems including cardiovascular disease, diabetes, some types of cancer and reduced life expectancy. Although overweight has many and complex determinants, increasing calorie intake, coupled with a more sedentary lifestyle, is the root of the problem. More than 53 % of the EU population are estimated to be overweight (IASO, 2008), and the numbers are increasing (WHO, 2008). Excessive intake of high-energy food, often cheaper, heavily advertised and more easily available than more healthy food, plays an important role. Although not all healthy food has low environmental impacts and vice versa, several dietary recommendations, such as a higher proportion of cereals, potatoes, vegetables and fruit in diets, and less meat, are beneficial both to human health and to the environment (Figure 4.2). Higher calorie intakes combined with sedentary lifestyles do not only have adverse health effects but also mean that more food has to be produced, resulting in higher life-cycle environmental impacts than diets based on recommended healthy calorie intakes. Insufficient physical activity is another very relevant factor for overweight, obesity, and their related health problems. In addition to individual behaviour/life style-related choices, physical activity depends on many conditions, including mobility patterns, access to walkable neighbourhoods, safe green areas, as well as infrastructure, promoting physical activity. Overweight people report that they walk less (Eurostat, 2006) and tend to live in low-density areas and with a higher dependency on car-based transport, although the nature of this association is highly complex (Scottish Government, 2008; Eid et al., 2007).16 The European environment | State and outlook 2010

Thematic assessment | Consumption and the environment 3 Understanding what shapes current and potential future consumption Private consumption is shaped by an array of complex non‑renewable resources in response to global increases and interrelated factors, including demographics; income in demand, and rising food prices (see Chapter 4). These and prices; trade, globalisation and technologies; supply resource price increases were alleviated by the economic of goods and services and how they are marketed; downturn but could well reappear when a period of stable information and transparency on products and services; economic growth returns. policies; housing and infrastructure, as well as social and psychological factors such as habits, culture and taste Rather than growth being a driver of future consumption (Mont and Power, 2010; Power and Mont, 2010). patterns, the potential for growth may in future depend to an increasing extent on how we consume.

The relevance of prices for consumer decisions means that, generally, consumers demand more of any product if the price goes down and less if the price increases. The 3.1 Economic influences on degree of change in demand resulting from a variation consumption in price depends on the price elasticity of that particular product or service. For example, price elasticities for basic The most important factor influencing consumption food items such as bread, milk and eggs are lower than for patterns is the level of disposable income at the individual restaurant meals, as going to a restaurant is much easier to household level (OECD, 2008a).
