A city is a human settlement of a notable size. The term "city" has different meanings around the world and in some places the settlement can be very small. Even where the term is limited to larger settlements, there is no universally agreed definition of the lower boundary for their size. In a more narrow sense, a city can be defined as a permanent and densely settled place with administratively defined boundaries whose members work primarily on non-agricultural tasks. Cities generally have extensive systems for housing, transportation, sanitation, utilities, land use, production of goods, and communication. Their density facilitates interaction between people, government organizations, and businesses, sometimes benefiting different parties in the process, such as improving the efficiency of goods and service distribution.
Sustainable transport refers to ways of transportation that are sustainable in terms of their social and environmental impacts. Components for evaluating sustainability include the particular vehicles used for road, water or air transport; the source of energy; and the infrastructure used to accommodate the transport. Transport operations and logistics as well as transit-oriented development are also involved in evaluation. Transportation sustainability is largely being measured by transportation system effectiveness and efficiency as well as the environmental and climate impacts of the system. Transport systems have significant impacts on the environment, accounting for between 20% and 25% of world energy consumption and carbon dioxide emissions. The majority of the emissions, almost 97%, came from direct burning of fossil fuels. In 2019, about 95% of the fuel came from fossil sources. The main source of greenhouse gas emissions in the European Union is transportation. In 2019 it contributes to about 31% of global emissions and 24% of emissions in the EU. In addition, up to the COVID-19 pandemic, emissions have only increased in this one sector. Greenhouse gas emissions from transport are increasing at a faster rate than any other energy using sector. Road transport is also a major contributor to local air pollution and smog.
The Erasmus Programme is a European Union (EU) student exchange programme established in 1987. Erasmus+, or Erasmus Plus, is the new programme combining all the EU's current schemes for education, training, youth and sport, which was started in January 2014.
A sister city or a twin town relationship is a form of legal or social agreement between two geographically and politically distinct localities for the purpose of promoting cultural and commercial ties.
The Core Cities Group is a self-selected and self-financed collaborative advocacy group of large regional cities in the United Kingdom outside Greater London and Edinburgh. The group was formed in 1995 and serves as a partnership of eleven city councils: Belfast, Birmingham, Bristol, Cardiff, Glasgow, Leeds, Liverpool, Manchester, Newcastle, Nottingham and Sheffield.
Agoria, previously known as Fabrimetal, is a Belgian employers' organization and member of the Federation of Belgian Enterprises.
Relations between the European Union and the United States began in 1953, when US diplomats visited the European Coal and Steel Community in addition to the national governments of its six founding countries. The two parties share a good relationship which is strengthened by NATO, cooperation on trade, and shared values.
The European Institute of Innovation and Technology (EIT) is an independent body of the European Union with juridical personality, established in 2008 intended to strengthen Europe's ability to innovate. The EIT’s three “core pillars” of activities are: entrepreneurial education programmes and courses across Europe that transform students into entrepreneurs; business creation and acceleration services that scale ideas and budding businesses; and innovation-driven research projects that turn ideas into products by connecting partners, investors, and expertise.
A sustainable city, eco-city, or green city is a city designed with consideration for social, economic, environmental impact, and resilient habitat for existing populations, without compromising the ability of future generations to experience the same. The UN Sustainable Development Goal 11 defines sustainable cities as those that are dedicated to achieving green sustainability, social sustainability and economic sustainability. They are committed to doing so by enabling opportunities for all through a design focused on inclusivity as well as maintaining a sustainable economic growth. The focus will also includes minimizing required inputs of energy, water, and food, and drastically reducing waste, output of heat, air pollution – CO2, methane, and water pollution. Richard Register, a visual artist, first coined the term ecocity in his 1987 book Ecocity Berkeley: Building Cities for a Healthy Future, where he offers innovative city planning solutions that would work anywhere. Other leading figures who envisioned sustainable cities are architect Paul F Downton, who later founded the company Ecopolis Pty Ltd, as well as authors Timothy Beatley and Steffen Lehmann, who have written extensively on the subject. The field of industrial ecology is sometimes used in planning these cities.
ICLEI – Local Governments for Sustainability is an international non-governmental organization that promotes sustainable development. ICLEI provides technical consulting to local governments to identify and meet sustainability objectives. It has a strong focus on biodiversity and has worked across local, national, and global levels. ICLEI was the first and is the largest transnational network of local governments engaging in climate action.
C40 Cities Climate Leadership Group is a group of 96 cities around the world that represents one twelfth of the world's population and one quarter of the global economy. Created and led by cities, C40 is focused on fighting the climate crisis and driving urban action that reduces greenhouse gas emissions and climate risks, while increasing the health, wellbeing and economic opportunities of urban residents.
Interreg is a series of programmes to stimulate cooperation between regions in and out of the European Union (EU), funded by the European Regional Development Fund. The first Interreg started in 1989. Interreg IV covered the period 2007–2013. Interreg V (2014–2020) covers all 27 EU member states, the EFTA countries, six accession countries and 18 neighbouring countries. It has a budget of EUR 10.1 billion, which represents 2.8% of the total of the European Cohesion Policy budget. Since the non EU countries don't pay EU membership fee, they contribute directly to Interreg, not through ERDF.
A smart city is a technologically modern urban area that uses different types of electronic methods and sensors to collect specific data. Information gained from that data is used to manage assets, resources and services efficiently; in return, that data is used to improve operations across the city. This includes data collected from citizens, devices, buildings and assets that is processed and analyzed to monitor and manage traffic and transportation systems, power plants, utilities, urban forestry, water supply networks, waste, criminal investigations, information systems, schools, libraries, hospitals, and other community services. Smart cities are defined as smart both in the ways in which their governments harness technology as well as in how they monitor, analyze, plan, and govern the city. In smart cities, the sharing of data is not limited to the city itself but also includes businesses, citizens and other third parties that can benefit from various uses of that data. Sharing data from different systems and sectors creates opportunities for increased understanding and economic benefits.
Transport in the European Union is a shared competence of the Union and its member states. The European Commission includes a Commissioner for Transport, currently Adina Ioana Vălean. Since 2012, the commission also includes a Directorate-General for Mobility and Transport which develops EU policies in the transport sector and manages funding for Trans-European Networks and technological development and innovation, worth €850 million yearly for the period 2000–2006.
The Covenant of Mayors is a European co-operation movement involving local and regional authorities. Signatories of the Covenant of Mayors voluntarily commit to increasing energy efficiency and the use of renewable energy sources on their territories. By their commitment, they support the European Union 20% CO2 reduction objective to be reached by 2020.
Sea transport accounts for most of the European Union's external and internal commerce. The EU is the world's third-largest importer of fisheries and aquaculture products and the fifth-largest producer. Maritime borders make up more than 70% of the Union's external borders, and hundreds of millions of travelers pass through European ports each year. The security of Europe's energy supply is heavily reliant on marine transit and infrastructure. The significant expansion of EU Member States' fleets, as well as suitable port infrastructure, contribute to a well-functioning energy market and supply security, and hence to European residents' and the European economy's overall well-being. The Arctic region is therefore a vital new area for the EU to work towards and a new strategy for the Arctic region that matches with the European Green deal was established in late 2021.
The Cities for Climate Protection program (CCP) is one of three major global transnational municipal networks aimed at reducing urban greenhouse gas emissions. Established in 1990 by the International Union of Local Authorities and the United Nations Environment Programme, one of the largest global transnational networks, the International Council for Local Environment Initiatives (ICLEI), presented a framework to represent local government environmental concerns internationally. The ICLEI strives to ‘establish an active and committed municipal membership… that promotes environmental and sustainable development initiatives within…[a] framework of decentralised cooperation’. In 1993, subsequent to an ICLEI successful pilot scheme, the Urban CO2 Reduction Project, the CCP program was established during the post-Rio Earth Summit era. The CCP program illustrates itself within local climate policy, as a Transnational governance network.
Soil governance refers to the policies, strategies, and the processes of decision-making employed by nation states and local governments regarding the use of soil. Globally, governance of the soil has been limited to an agricultural perspective due to increased food insecurity from the most populated regions on earth. The Global Soil Partnership, GSP, was initiated by the Food and Agriculture Organization (FAO) and its members with the hope to improve governance of the limited soil resources of the planet in order to guarantee healthy and productive soils for a food-secure world, as well as support other essential ecosystem services.
The European Green Deal, approved in 2020, is a set of policy initiatives by the European Commission with the overarching aim of making the European Union (EU) climate neutral in 2050. The plan is to review each existing law on its climate merits, and also introduce new legislation on the circular economy, building renovation, biodiversity, farming and innovation.
Climate change and cities are deeply connected. Cities are one of the greatest contributors and likely best opportunities for addressing climate change. Cities are also one of the most vulnerable parts of the human society to the effects of climate change, and likely one of the most important solutions for reducing the environmental impact of humans. The UN projects that 68% of the world population will live in urban areas by 2050. In the year 2016, 31 mega-cities reported having at least 10 million in their population, 8 of which surpassed 20 million people. However, secondary cities - small to medium size cities are rapidly increasing in number and are some of the fastest growing urbanizing areas in the world further contributing to climate change impacts. Cities have a significant influence on construction and transportation—two of the key contributors to global warming emissions. Moreover, because of processes that create climate conflict and climate refugees, city areas are expected to grow during the next several decades, stressing infrastructure and concentrating more impoverished peoples in cities.
