This report presents the detailed analysis of eight urban environmental sustainability nexus. These constitute examples to help understand the complexity of urban systems and explore how, in practice, using nexus analysis can help identifying existing challenges, potential trade-offs and co-benefits on actions to achieve urban sustainability objectives and opportunities to move towards better coordinated and integrated policy and action. Findings have been summarized in the main Urban Sustainability in Europe – Avenues for change report.
It is becoming increasingly clear that the complex and interrelated challenges of climate change, environmental degradation and rising inequality will not be solved without a fundamental transformation of our societies. Far-reaching changes are needed to our technologies and infrastructures, cultures and lifestyles, as well as adaptations to the corresponding governance and institutional frameworks. Around the world, these important system innovations are converging in cities.
This report, building on the experience of both the EEA and Eionet, presents a synthesis of global and European megatrends with illustrations of key emerging trends, wild cards and uncertainties. It aims to inform about on‑going, emerging and potential future developments, raise awareness and contribute to the diffusion of anticipatory thinking.
People’s awareness of air pollution and the associated risks to their health and that of their children has grown significantly over recent years, often informed by local or national campaigns led by non-governmental organisations (NGOs) as well as by media coverage. In some countries, groups of concerned citizens, often supported by NGOs, have taken authorities to court over air quality issues, and the courts have ruled in favour of the right to clean air in several instances.
Green infrastructure is a strategically planned network of natural and semi-natural areas, which include other environmental features designed and managed to deliver a wide range of ecosystem services. These include water purification, air quality, space for recreation and climate mitigation and adaptation. This network of green (land) and blue (water) spaces can improve environmental conditions and therefore citizens' health and quality of life. It also supports a green economy, creates job opportunities and enhances biodiversity. To maximise the benefits it provides, GI should be an essential component of spatial and physical planning. Developing GI is a key step towards successfully implementing the EU 2020 biodiversity strategy. Target 2 of the strategy requires that ‘by 2020, ecosystems and their services are maintained and enhanced by establishing green infrastructure and restoring at least 15 % of degraded ecosystems.’
This report shows that, although cities and municipalities across Europe increasingly acknowledge the need to adapt to climate change, meeting the costs of measures for adaptation remains very often a major challenge. Nevertheless, the report presents examples of several cities and municipalities that have found innovative ways of financing adaptation and implementing measures. These range from classic funds to more innovative financing mechanisms, including crowdfunding and green bonds. These solutions could be relevant for other cities, towns and smaller municipalities, and the examples are meant as an inspiration to learn from.
Most European cities have at least one river or lake crossing their urban landscape. Urbanisation has come at a cost to rivers and lakes, as they have been heavily degraded to enable development, carry waste, supply drinking water and facilitate transport and industry.
This report builds on and complements existing products and initiatives on urban adaptation in Europe. It focuses on the state of actions in the field and progress achieved since the first EEA report in 2012, and it considers this analysis in relation to current challenges: Do existing actions lead to attractive, climate-resilient cities and if not, what needs to be changed? The report aims to broaden perspectives and provide input to a review and subsequent adjustment of urban adaptation to climate change by local governments and by supporting regional, national and European institutions, researchers and other relevant stakeholders.
This report provides a comparable measurement of urban sprawl for 32 European countries at three levels (the country level, the NUTS-2 region level and the 1-km2 cell level) and for two years (2006 and 2009). The analysis is based on the Copernicus system which monitors the Earth and collects data by different sources. This data provides information about a number of thematic areas, including land. Under land a pan-European component delivers information about various areas, including the level of sealed soil (imperviousness), through high resolution layers taken from satellite imagery. The analysis uses new urban sprawl metrics taking into account the way built-up areas are laid out and how they are used. It also looks at the factors which contribute to an increase or decrease in urban sprawl. The results confirm the conclusions of earlier EEA reports namely that in many parts of Europe current levels of urban sprawl have contributed to detrimental ecological, economic and social effects. This gives cause for concern and such effects may increase alongside planned urban development.
Cities are key players in minimising the use of resources and in developing the circular model. Generally, municipalities provide utilities and control public services for citizens and businesses that influence the majority of resource and energy use and the production of emissions and waste. Local authorities have the capacity to implement responses at multiple scales. This report analyses both the supply and the demand issues. It is divided into two parts: the first is devoted to how to avoid, prevent and reduce the use of resources; the second addresses reuse, recycling and harvesting.
The report introduces the concept of urban metabolism, the circular model and the role of compactness in urban resource efficiency. Cities require natural resources and energy to sustain the activities and daily life of the urban population. Nevertheless, there are opportunities to minimise the use of resources needed to sustain urban life and to reduce waste and emissions. As the urban form shapes the way people live, work and move, compact cities offer great potential to reduce the dependence on natural resources and energy. Urban planning, based on a vision of the future and developed with local stakeholders and crossing administrative borders, is a key factor in increasing the density of urban areas.
Shifting to a resource-efficient society is not just a question of technological change but a systemic one. It is a process that assumes fundamental changes in the governance, economy, social structure, culture and practices of the societal system. This report analyses challenges and opportunities for enabling resource-efficient cities.
Sharing knowledge bases to support environmental and resource-efficiency policies and technical improvements
In 2010, the EEA produced its first assessment of global megatrends as part of its five-yearly assessment of the European environment’s state, trend and prospects (SOER 2010). In preparation for SOER 2015, the EEA updated each of the megatrends, providing a more detailed analysis based on the latest data. This publication is one of the 11 updates being published separately. In mid-2015 the chapters will be consolidated into a single EEA technical report.
This TERM 2013 report includes an assessment of progress towards the transport-related environmental targets set out in the 2011 White Paper and other transport and environment regulations. It also includes a focus on the environmental impacts of urban transport.
Almost three quarters of Europeans live in cities. The air quality in our cities is therefore of significant importance to the health of Europeans. Considerable progress has been made in the past twenty years in improving urban air quality, but issues remain. A number of different air pollutants such as nitrogen dioxide, particulate matter, and ozone remain above regulated levels, posing a threat to human health. This report describes a European pilot project to help identify and address the reasons underlying this 'gap' in implementation of air quality policy in 12 European cities, and thereby draw lessons of wider relevance.
