About three-quarters of Europeans live in cities, according to UN-Habitat. Cities, with their concentrated population and infrastructure, are especially vulnerable to certain effects of climate change and other environmental stresses like heatwaves, flash floods, pollution, noise, and soil contamination. Their aggregated consumption patterns can also lead to biodiversity loss. According to our estimates, in 2020, 96% of people living in EU cities were exposed to levels of air pollution by fine particulate matter (PM2.5) above the WHO guideline.
Also, building stock accounts for 40% of energy consumption and 36% of GHG emissions. At present, 75% of the European building stock is energy inefficient.
All these aspects have a disproportionate impact on vulnerable segments of the population and can exacerbate social challenges like segregation, poverty and inequality.
At the same time, however, cities are hubs of creativity, innovation and education, and have the capacity to affect significant systemic changes across a range of critical environmental issues. Cities have their own governments and are often best placed for local action to tackle and resolve environmental challenges. Historically, municipalities have played a crucial role in improving waste, wastewater and water management, public transport and land use via integrated urban planning approaches. Today, they have an increasingly central role in tackling climate change mitigation and adaptation, ecosystem preservation and restoration and circular economy. In addition, the presence of accessible, high-quality green spaces in cities supports physical and mental health and social well-being.
Still, more must be done to create truly sustainable European cities. Recent EU policies aim to enhance cities’ resilience and their capacity to transition towards sustainability.
Sustainable urban development refers to the process of creating livable and environmentally-friendly urban areas while addressing economic, social, and environmental challenges. It aims to achieve a balance between the needs of the community and the natural environment.
refers to the practice of creating cities that are environmentally sound and socially equitable, taking into consideration the needs and experiences of diverse communities.
Urban sustainability refers to the ability of a city or urban area to meet the needs of the present without compromising the ability of future generations to meet their own needs. Ensuring urban sustainability can be challenging due to a range of social, economic, and environmental factors.
While many community dynamics are at work, three are particularly important to building healthy and prosperous communities over the long term: economy, ecology, and equity—the three E's. Economy is the management and use of resources to meet household and community needs.
Sustainable urban living includes several aims including the use of renewable resources, energy efficiency, use of public transport, accessible resources and services.
Sustainable urban systems provide a high quality of life – with economic, social, and environmental benefits distributed equitably across the community – in the face of natural, climate, technological, and societal disruptions.
What is urban sustainability? Urban sustainability is a way planning cities that aims to improve the social, economic, and environmental conditions of a city to ensure the quality of life for current and future residents.
Increasing greenhouse gas emissions and strain on resources jeopardize the ability of future generations to thrive on Earth. Urban sustainability aims to restructure urban environments in ways that do not deplete resources for future generations and curb the effects of climate change.
The six main challenges to urban sustainability include: suburban sprawl, sanitation, air and water quality, climate change, energy use, and the ecological footprint of cities. Other urban sustainability challenges include industrial pollution, waste management, and overpopulation.
Cities, with their concentrated population and infrastructure, are especially vulnerable to certain effects of climate change and other environmental stresses like heatwaves, flash floods, pollution, noise, and soil contamination. Their aggregated consumption patterns can also lead to biodiversity loss.
One of the most effective strategic approaches to sustainable urban development is the use of green infrastructure. Green infrastructure, such as green roofs, green walls, permeable paving, urban gardens, and rain gardens incorporate plants, soils, and natural elements into the built environment.
This means the main ways cities can become greener are to: Reduce the amount of energy and resources used through improving the efficiency of systems, for example transport, and changing citizens' behaviours. Reuse and recycle waste energy and materials. Obtain energy from cleaner sources.
Principle 1: The planet has biophysical limits. Principle 2: Human and natural systems are tightly intertwined and come together in cities. Principle 3: Urban inequality undermines sustainability efforts. Principle 4: Cities are highly interconnected.
Urban areas often have high population densities, intricate transport networks and dense commercial and industrial areas, which can compound existing environmental and health issues, and exacerbate social inequalities. At the same time, cities have the capacity to shape the transition to a more sustainable future.
What is Sustainable Urban Development? Sustainable urban development is defined as development that meets the needs of a community without compromising the ability of future generations to meet their own needs. It prioritizes economic, environmental and social sustainability.
