Sustainable Mobility in the Century of Metropolises: Case Study of Greater London

1. Introduction

The twentieth century is called the “metropolitan century” (UN-Habitat, 2020), mainly because those metropolises represent approximately 53% of the world’s population (OECD, 2018). It’s projected that around 325 new metropolitan areas will emerge globally by 2035. Population growth is expected to be led by Asia and Africa, while Europe’s population will remain stable and Latin America will experience slower growth. Presently, Asia is home to 1,038 metropolitan areas, accounting for 56.11% of the total. This is followed by Western Europe with 325 metropolitan areas (15.76%), Latin America and the Caribbean with 215 (12.5%), Africa with 235 (11.7%), and Eastern Europe with 121 (3.9%). In addition to this, the municipalities, which are part of the metropolitan areas, can represent a third of the national world economy (UN-Habitat, 2020)

The rapid growth of metropolitan regions, especially in Asia and Africa, spotlights the necessity for in-depth research on urban expansion and demographic transitions. As urban landscapes evolve, they present unique challenges and opportunities, demanding a comprehensive understanding of territorial development and mobility. This includes not just growth management but also ensuring sustainable and harmonious urban expansion that integrates human and environmental elements. Such an approach necessitates a nuanced understanding of urban dynamics, bridging the gap between theoretical models and the complex realities of metropolitan life.

Despite global efforts by the UN (2020) and OECD (2018) to standardize the definition of metropolises, research often neglects the intricate relationship between human activities and goods movement. Effective management of these densely populated and economically pivotal areas requires a focus on infrastructure, urban networks, and mobility, tailored to each metropolis’s unique characteristics, including mobility, migration, economic growth, and community needs. Addressing the critical role of mobility within metropolises necessitates specific legislative and planning efforts to cater to the complex interplay of factors that shape urban life (ITF, 2021; UN Habitat, 2020; Moreno-Monroy et al., 2020); Lermana et al., 2020; Brömmelstroet & Verkade, 2020; Orum & Collins, 2019; Dijkstra et al., 2019; Nikolaeva et al., 2019; Benini, 2018; Peres et al., 2018; BRASIL, 2015; Costa et al., 2014; Harrison and Growe, 2014; BRASIL, 2012; Brenner, 2011; Yigitcanlar et al., 2008; Venables, 2005; Jessop et al., 2008; Antrop, 2004; Moura & Cardoso, 2004; Holmes et al., 2000; Ciechocinska, 1984).

Bridging these insights, the transition from a general framework to a more granular analysis exemplifies the leap from standardized definitions of urban areas to the nuanced understanding required to grasp the dynamics of Functional Urban Areas (FUAs) in Europe, where the intricate tapestry of mobility and urbanism transcends mere geographic or administrative boundaries. Functional Urban Areas (FUAs) in Europe, based on urban centers and local units, highlight the complex relationship between metropolises and mobility. However, regional mobility’s intricacy often exceeds municipal boundaries, challenging the definition and analysis of metropolises (Dijkstra et al., 2019).

Academic research is essential for comprehending the complexities of urban development and the pivotal role of mobility in shaping cities. Studies from as Xue et al., (2022), Kulkarni et al., (2019), Zheng and Chen (2019), Lim et al. (2019), Guidotti et al. (2016), Cho et al. (2011), González et al. (2008) and Brockmann et al. (2006) highlight this interplay, demonstrating how urban planning and mobility are mutually influential. This concept, eloquently summarized by Winston Churchill in 1944: “First we shape our mobility system, and afterwards that mobility system shapes us” as noted by Brömmelstroet & Verkade (2020) and Te Brömmelstroet et al. (2021). Academic research is crucial also for understanding Metropolitan Areas, their growth complexities, and the influence of mobility on urban development. Similarly, studies on metropolitan mobility are deepened by an extensive scholarly foundation, leveraging insights from both historical and recent contributions. Abou Jaoude et al. (2022), Barbera & Rossi (2021), IPCC (2021), Maheshwari et al. (2020), and Goodspeed (2020), UN (2015, 2020), Sennett (2018), Lundqvist (2016), Harrison & Growe (2014), Jessop et al. (2008) and Santos (1979, 1985), offer valuable insights for understanding the complexities of mobility in metropolitan areas.

Mobility profoundly influences urban life, affecting economic, political, and societal dimensions (UN-Habitat, 2020). It is a key driver of regional growth and enriches urban experiences, reflecting societal behaviors (Meredith et al., 2021; Vidovic et al., 2019). Analyzing community dynamics shows the impact of population density on movement and addresses emerging needs. Moreover, mobility’s link to sustainability is undeniable, with transportation being a major contributor to emissions—particularly, automobiles, which are responsible for 80% of these emissions (IPCC, 20211; Nikolaeva et al., 2019; Zignani et al., 2013). Consequently, transitioning to sustainable mobility practices is essential. Frameworks like the New Urban Agenda and Sustainable Development Goals highlight sustainable mobility’s role in fostering resilient urban communities (UN-Habitat, 2020). The significance of sustainable mobility in urban contexts, particularly its role in addressing climate change through decarbonization, housing risk assessments, and urban transport policies, is crucial (Boland et al., 2023; Winklet et al., 2023; Drummond, 2021; Palliyani & Lee, 2017; Mavrogianni et al., 2015). This emphasis aligns with efforts to improve intelligent transport systems and to understand the wider impact of mobility on urban development (Larkin et at.; 2017; Richter & Ruhl, 2013). An in-depth grasp of urban dynamics, encompassing governance and sustainable mobility, is essential for effective urban planning (Johson & Hasrstad, 2022; Krukle et al., 2019; Contreras Platania, 2019). The UK’s Office for Science (2013) underscores the need for long-term planning and evidence-based policymaking, projecting the paths of urban development and sustainability until 2065 and advocating for a unified approach to the effects of climate change on mobility (Ferris, 2020).

London’s experiences encapsulate the broader context of urban mobility and sustainability, stressing the importance of comprehending how cities manage sustainable mobility’s complexities. This research aims to unravel how metropolises like Greater London tackle sustainable mobility challenges and opportunities. The research question is: How are the different dimensions of mobility perceived and what are the essential attributes needed to guarantee the sustainability of a metropolitan region?

The main objective of this study is to analyze the different dimensions of mobility as a function of common interest and to define the necessary attributes to make a metropolitan region sustainable. Achieving this broad aim involves two targeted goals. The first specific goal is to explore perceptions of diverse stakeholders regarding the various dimensions of mobility, with the objective of uncovering how these dimensions are understood and prioritized in the context of sustaining metropolitan regions. This step is crucial for highlighting the spectrum of stakeholder views on mobility’s impact on essential urban interests like accessibility, environmental sustainability, and social inclusivity, using qualitative research methods. The second specific goal aims to distill and articulate the essential attributes of mobility that are considered vital by stakeholders for the sustainability of metropolitan regions. This involves a qualitative analysis to pinpoint both agreements and differences in stakeholder opinions on what makes mobility sustainable, focusing on aspects such as policy frameworks, technological advancements, and strategies for community engagement. These specific goals not only support the main objective but also deepen our comprehension of mobility’s critical role in fostering sustainable metropolitan environments.

This study is structured into four principal sections, beginning with the Theoretical Background, which explores the Metropolitan Phenomenon, Greater London, and its recent policies and programs. Following this, the Method section describes the case study approach, qualitative research phase, and data collection methods employed. The third section, Findings, presents an analysis of general documents related to Greater London, the evaluation of interviewees, and the subcategories for examination. The study concludes with Concluding Remarks, summarizing its contributions to academic discourse on the subject and providing insightful, substantiated conclusions.

2. Theoretical Background

2.1. Metropolitan Phenomenon

The term “metropolis,” originally meaning a mother city in Greek, now signifies power and prestige in various contexts. Modern definitions vary, including megalopolis, metropolitan regions, urban agglomerations, and Functional Urban Areas, each applying specific criteria to identify metropolitan characteristics (Celestino, 2021; UN, 2020; Fang and Yu, 2017; Moreno-Monroy et al., 2020; Smith, 2013; Catalán and Serra, 2008; Kennedy et al., 2005; Keene, 2004; Luck and Wu, 2002; Hansen, 1959). Cities shaped by historical contexts require sound urban planning due to their impact on mobility, crucial for socioeconomic growth. Mobility, encompassing urban movements, reveals behavioural patterns and connects people, goods, and locations (Meredith et al., 2021; Vidovic et al.,, 2019; Zignani et al., 2013). Sustainable mobility, balancing environmental and socioeconomic factors, aligns with global policies and integrates mobility analyses into urban dynamics (UN-Habitat, 2020; Krukle et. at., 2019). The interplay between metropolitan areas, mobility, and climate change necessitates comprehensive adaptation strategies. Research highlights the importance of community-led initiatives and sustainable transport solutions in reducing greenhouse gas emission (Creutzig et al., 2012; Sudhakara Reddy & Balachandra, 2012; Smit & Wandel, 2006). The Urban Adaptation Index (UAI) and Sustainable Urban Mobility Plans (SUMPs) address urban mobility sustainably, balancing climate objectives with equitable accessibility (Neder et al., 2021; Arsenio et al., 2016). This study evaluates urban resilience and mobility strategies, using theoretical frameworks to inform sustainable policymaking.

The research is based on Walter Christaller’s Central Place Theory (1966) and the Growth Pole Theory (1955). Ribeiro and Fachinelli (2021) identified commonalities between these theories. The analysis involved: (i) identifying basic concepts from each theory; (ii) interpreting concepts in relation to metropolitan realities; (iii) correlating concepts between theories; (iv) detecting conditions crucial for each concept; (v) developing a minimal classification for concepts. Key concepts include: (i) territory study necessitates location; (ii) functional hierarchy depends on scale; (iii) regions require vision coverage; (iv) mobility is essential for connection and road dependency; (v) urban networks involve mobility; (vi) urbanization links to a phenomenon; (vii) investment concentration requires economic context analysis.

Converging concepts in both theories require specific conditions, categorized as physical (tangible aspects) or non-physical (intangible phenomena). Each concept’s existence depends on fulfilling its primary condition, forming a hierarchical structure essential for understanding urban and metropolitan dynamics. (Ribeiro & Fachinelli, 2021).

In the 21st century, cities confront challenges such as urbanization and climate change. Benko (2002) and Harrison and Growe (2014) discuss how globalization centralizes economic power in cities, altering urban dynamics. Mi & Coffman (2019) explore the sharing economy’s contribution to sustainability and urban mobility. Barbera and Rossi (2021), Sennet (2018) and Ellin (2006) introduces the “open city” concept, advocating for porosity in urban planning to enhance integration. The UN-Habitat (2020) emphasizes urban areas’ role in achieving Sustainable Development Goals through sustainable urbanization. Additionally, the text highlights the importance of integrating climate considerations into urban planning, as noted by the IPCC (2021), Maheshwari et al. (2020) and Lundqvist (2016). It concludes with the advocacy by Abou et al., (2022) and Goodspeed (2020) for scenario planning as a strategic tool to address urban challenges, emphasizing adaptability and stakeholder involvement for a more resilient and inclusive urban future.

Ribeiro and Fachinelli (2021) integrates these concepts, demonstrating that the study of metropolitan phenomena can be approached through the analysis of various dimensions including territory, scale, place, networks (JESSOP et al., 2008), urbanization (Harrison and Growe, 2014) urban economy, (Benko, 2002) culture and identity, (Sennet, 2018; Barbera and Rossi, 2021) innovation, (UN, 2015, 2020) climate change, (IPCC, 2021; Maheshwari et al., 2020; Lundqvist, 2016) and foresight (Abou et al.. 2022; Goodspeed, 2020).

2.2. Greater London

In the contemporary urban landscape, the intricate dynamics between climate change response and urban mobility have emerged as pivotal determinants of metropolitan sustainability. Analyzing London’s Climate Response and its Implications for Metropolitan Sustainability seeks to illuminate this nexus, focusing on London’s strategic endeavors to navigate the challenges posed by climate change. Through an in-depth examination of initiatives such as the UK Climate Impacts Program (UKCIP) and the thorough assessment of climate impacts, this study endeavors to unravel how mobility, in its myriad forms, plays a crucial role in fostering or impeding the sustainability of metropolitan regions.

London’s diverse strategies to enhance environmental sustainability and mobility are central to this analysis. The research highlights key mobility attributes identified by stakeholders as essential for the sustainable development of metropolitan areas. Additionally, the study provides a strategic analysis of London’s environmental initiatives, emphasizing the London Environment Strategy’s shift towards integrating urban mobility with environmental sustainability.

By examining London’s comprehensive strategies for improving air and water quality, reducing greenhouse gas emissions, and strengthening flood defenses, this study aligns with the broader academic goal of identifying critical elements for metropolitan sustainability. It emphasizes the importance of integrating stakeholder perspectives with environmental strategies, presenting a framework for sustainable mobility that addresses climate change impacts and enhances urban livability.

This holistic approach demonstrates London’s commitment to creating a resilient, sustainable, and thriving metropolitan region. The city’s model of integrating environmental sustainability into urban mobility planning and policy development serves as a valuable reference for other metropolitan areas.

2.3. Mobility and Environmental Sustainability: Analyzing London’s Climate Response and Its Implications for Metropolitan Sustainability

This study seamlessly aligns with analyzing mobility’s role in fostering sustainable metropolitan regions, focusing on London’s climate change response through the UK Climate Impacts Program (UKCIP) and comprehensive climate impact assessments. Emphasizing climate scenarios, environmental, social, and economic impacts, and adaptation strategies highlights the critical interplay between sustainability and urban mobility (UKCIP, 2002).

The climate impact studies and adaptation options provide a foundation for exploring mobility’s essential attributes for metropolitan sustainability. Examining issues like flooding, water resources, health, biodiversity, and transport offers insight into urban mobility’s environmental dimensions and its interconnectedness with urban planning and policymaking. Adaptation options and policies, such as sustainable urban drainage systems, water-efficient appliances, and infrastructure adjustments, are integral to sustainable mobility frameworks. These measures address climate change impacts, improve urban livability, reduce reliance on unsustainable transport, and promote green spaces. Integrated planning and a multifaceted approach to climate change impacts align with the study’s broader objectives, emphasizing sustainability and resilience in urban mobility planning. Comprehensive strategies across sectors, as seen in Greater London’s transport, economic development, and emergency preparedness approaches, exemplify the holistic perspective needed for sustainable metropolitan regions (UKCIP, 2002).

2.4. Integrating Urban Mobility and Environmental Sustainability: A Strategic Analysis of London’s Environmental Initiatives (2018)

The 2018 London Environment Strategy aligns with this study’s objectives to analyze mobility dimensions and define attributes for sustainable metropolitan regions. This evolution from initial climate change responses to strategizing sustainability marks a paradigm shift towards integrating mobility and environmental sustainability (GLA, 2018).

London’s commitment to improving air and water quality, reducing greenhouse gas emissions, and bolstering flood defenses exemplifies a multifaceted approach to sustainability. These measures are essential for creating a resilient metropolitan region. The emphasis on revitalizing urban spaces and mitigating climate change aligns with the study’s goals, highlighting the importance of stakeholder insights in shaping policies for a sustainable region (GLA, 2018).

The Greater London Authority’s strategy integrates stakeholder input, focusing on reducing carbon emissions, advancing renewable energy, and improving waste management. Enhancements to green infrastructure and air quality ensure the sustained viability of metropolitan regions. The strategy’s multi-dimensional approach blends policy measures with objectives, fostering a greener, sustainable, and resilient city prepared for future challenges. This strategy underscores the importance of effective governance, sustainable urban development, and robust infrastructure in environmental stewardship, paralleling the scholarly emphasis on sustainable mobility (GLA, 2018).

3. Method

3.1. Case Study

The research strategy adopted through the case study method is widely utilized by various authors across different topics related to metropolises as urban mobility (Melikov et al., 2021) levels of information mobilization for citizens (Uppal, 2021); the phenomenon of reurbanization (Duarte Alonso et al., 2018); collaborative planning (Deyle & Wiedenman, 2014); the perspective of elderly customers in delibery service (Byrne et al., 2012); case study understanding (Flyvbjerg, 2011); metropolitan planning organization (Fu et al., 2007). The study conducted by Eisenhardt (1989) synthesizes various previous research (Miles and Huberman, 1984; Yin, 1981; Glasser and Strauss, 1967) and proposes an analytical framework for case studies. The author outlines seven stages for conducting case study research with the aim of validating theories and applying them to the chosen study object. These re-search phases include Development of Instruments and Protocols, Data Collection, Data Analysis, Formulation of Hypotheses, and Conclusions.

The methodology employed in this study included data analysis, review of academic studies and documents, and qualitative interviews. It utilized academic databases and inter-national platforms to identify references and studies exploring the relationship between metropolitan regions, mobility, and climate change. Additionally, it reviewed relevant literatura, including books and scientific articles, to understand the subject matter and its evolution within the context of this research. A specific focus was placed on analyzing current policies related to climate change in the Greater London area and their impact on mobility. Lastly, qualitative interviews were conducted with subject matter experts to gain insights into their perceptions regarding the research objectives. This comprehensive approach ensured a thorough understanding of the dynamics at play and supported the development of well-informed conclusions.

3.2. Qualitative Phase of Research

This research employs qualitative methodologies to examine urban and metropolitan issues, drawing on frameworks from Creswell and Clark (2018) and Denzin (2006). The study concerning Greater London is structured into five distinct phases: articulation of a multicultural researcher’s perspective, establishment of a theoretical paradigm, development of a research strategy, collection and analysis of data, and interpretation of results. This process begins with the formulation of research questions and selection of appropriate ethical paradigms, followed by comprehensive literature reviews and the application of chosen methodologies to probe the multicultural dynamics of Greater London.

The third and fourth phases are centered on qualitative interpretation and analysis, involving active engagement with diverse communities. This is accomplished through interviews across governmental, academic, and business sectors, focusing on participant selection, qualitative data analysis, and the synthesis of findings into the existing theoretical framework to produce a detailed report. The study incorporates interviews with eight experts, designed to delve into the intricacies of mobility and metropolitan issues as depicted in the main structure (Figure 1). This approach ensures a thorough exploration of the subjects, emphasizing the complexity and multifaceted nature of urban dynamics.

The questions were structured according to subcategories aligned with theoretical frameworks or references to recent studies (Table 1). They aimed to gather information that connects directly with the specific documents analyzed. This approach ensures a comprehensive exploration of the subject matter, enabling a detailed understanding of how current data and concepts within the field either align with or diverge from established theories and recent research findings. By doing so, the study seeks to uncover new insights and perspectives, contributing to the ongoing discourse in urban and metropolitan studies.

3.3. Data Collection

Over four months, interviews with multidisciplinary experts from sectors including community, academia, third sector, private, and public were conducted to gather diverse insights (Table 3).

Using the Zoom platform for individual interviews from November 2023 to January 2024, data collection spanned various research categories. Despite its broad scope, this study specifically focuses on the critical issue of climate change, aiming to consolidate findings within this pressing global context. All sessions were recorded with the partici-pants’ explicit consent, evidenced by signed informed and voluntary consent forms, except for one participant who chose to remain anonymous. After the interviews, audio recordings were transcribed word-for-word using the noota.ai platform to ensure the fidelity of the transcription. Researchers reviewed each transcription to verify the accuracy of the documented discussions, guaranteeing precise capture of the dialogues.

4. Findings

The findings were derived from an examination of key documents, publications related to Greater London, and an analysis of conducted interviews.

4.1. Greater London (General Documents)

London is a global city competing for international investment, talent, and tourism. By necessity, the city as spectacle must ramp up its multilevel urbanism to compete with other global cities. (Yoos, James and Blauvelt, 2016, p. 190)

Empire’s northward expansion and the city’s establishment under Emperor Claudius in 43 AD. Its Roman legacy still lingers in the City of London’s ancient gate names. After the Romans’ departure in 410 AD, London faced invasions by the Angles, Saxons, Vikings, and Normans, with the latter making London the capital in 1066. Despite calamities like the Great Fire of 1666, London thrived, especially known for St. Paul’s Cathedral and its expansion between the Cities of London and Westminster (Haywood, 1998). From post-Roman invasions to legal recognition as a metropolis, London’s history showcases resilience and administrative expansion.

The term “Metropolis” was legally recognized in 18552, defining London’s administrative reach beyond the City of London and leading to the formalization of the Metropolitan Region of London in 1888. This period saw London’s governance evolve, replacing parish councils with the Metropolitan Board in 1885.

The 1888 Local Government Act played a pivotal role in shaping the governance of London, frequently referencing the term “Metropolis” to signify its importance. The Act states:

In the application of this Act to the Metropolis, the following provisions shall have effect:

(1) The Metropolis shall, on and after the appointed day, be an administrative county for the purposes of this Act by the name of the administrative county of London. (LOCAL GOVERMENT ACT 1888, 40)

This clause officially designated London as an administrative county, thereby centralizing the city’s metropolitan services under a single administrative entity. The precise number of times “Metropolis” is mentioned underscores the legislative focus on London’s metropolitan status. According to Haywood (1998), the 19th century marked significant advancements with the introduction of railways in 1836 and the establishment of major train stations and the underground railway by 1862, reshaping London’s form and social structure.

In the 19th century, London’s population surged due to industrialization and emerging commercial hubs. Morris (1997, pag. 28) notes “The factory town produced the industrial slum” highlighting efforts like Regent’s Park to improve public health. Significant developments included the rebuilding of Parliament and the British Museum’s inauguration. Paul (2017) cites the Green Belt policy of the 1930s and the 1944 Greater London Plan as initiatives inspired by garden city ideas to organize housing and development.

• Post-war London saw the establishment of the Greater London Council (GLC) in 19653 and suburban expansion until the 1970s. Despite the GLC’s dissolution in 1986, London maintained an administrative framework of 32 boroughs and the City of London the City of London, each responsible for local planning (UDP) and services4 (Paul, 2017; Haywood, 1998).
• The late 20th century focused on sustainable development and economic regeneration (Haywood, 1998), with the Modern Architectural Research Group influencing urban modernism and the introduction of elevated pedestrian systems in the 1960s (Yoos et al., 2016) and other techniques explored movement patterns, economic, and transportation connections, reflecting London’s adaptability and planning evolution. (Parr, 2007; Batty, 2014; Coombes, 2014).
• The 21st century sees London engaging in global competition through urban strategies like “The Developing City 2050,” aiming for inward expansion (Yoos et al., 2016). This ambition sparks debates around urban growth versus Green Belt rigidity (Mace, 2018) or leading to an expansion far beyond its current size (Lloyd Jones, 2000). Effective planning must navigate jurisdictional complexities and align development with public transport (Keene, 2004; Mace, 2018).

Sustainable urbanization strategies are essential for balancing growth with ecological integrity, emphasizing urban planning’s role in mitigating climate impact on biodiversity(Saganeiti et al., 2023; Lampinen et al., 2023; Wilby and Perry, 2006). Policies must incorporate climate strategies into urban development, considering urbanization’s significant impact on land use driven by socioeconomic shifts (UN, 1993, 2001, 2015, 2020; Rahman et al., 2019; Dobraszczyk, 2017).
