Quantum computing is a form of computing based on the principles of quantum mechanics. Quantum computing promises to revolutionise society through technological solutions to previously unsolvable problems or by enhancing the capacities of current computational technologies. Additionally, quantum computing has the potential to revolutionise the humanities and social sciences. We denote the study of these changes as “quantum humanities”, whose study focuses on the potential of quantum computing. This paper proposes a research programme for quantum humanities, which includes the application of quantum algorithms to humanities research, reflection on the methods and techniques of quantum computing and evaluation of its potential societal implications. Moreover, we argue that, foundationally, quantum mechanics has serious implications for the ways in which data and information are used to produce seemingly objective technologies. Thus, quantum computing is a nexus for the study of knowledge itself. This research programme aims to define the field of quantum humanities and to establish it as a meaningful part of the humanities and social sciences.

Artificial Intelligence (AI) has started to impact many facets of the economy and people’s routine activities. This article contributes to our understanding of how the legal system is reacting to the ongoing uptake of AI and the disputes or right infringements this uptake creates. Select legal cases regarding the use of AI technology for automated decisions are reviewed, with a focus on filings in Europe and the USA. This exercise reveals which type of legal challenges can be expected when it comes to deploying automated systems in these jurisdictions. Additionally, incipient regulatory efforts targeting AI on both sides of the North Atlantic are introduced and briefly discussed. The paper sheds light on how different legal systems accommodate an emerging technology with disruptive potential and offers a mapping of exemplary legal risks for prospective actors or organisations seeking to develop and deploy AI.

Quantum computing research and development efforts have grown dramatically over the past decades, led in part by initiatives from governments around the world. Government quantum computing investments are often driven by national security or digital sovereignty concerns, with the language used depending on the geography involved. For example, a focus on “national security” and quantum computing is prominent in the USA, while European countries regularly focus on “digital sovereignty”. These phrases are often loosely defined and open to interpretation, and they share some common motivations and characteristics (but also have important differences). This paper identifies specific governmental entities typifying the national security/digital sovereignty perspectives, along with these organisations’ respective roles within national and international policy engagement in quantum computing. It analyses governmental structures, historical developments and cultural characteristics that contributed to this national security–digital sovereignty divide. Building on this analysis, we use the history of other technologies to illustrate how we might adapt tested policy approaches to modern political dynamics and to quantum computing specifically. We frame these policy approaches so that they do not overemphasise “digital sovereignty” or “national security”, but rather address interests shared across both concepts, with a view to facilitating international collaboration.

This policy-oriented article explores the sustainability dimension of digitalisation and artificial intelligence (AI). While AI can contribute to halting climate change via targeted applications in specific domains, AI technology in general could also have detrimental effects for climate policy goals. Moreover, digitalisation and AI can have an indirect effect on climate policy via their impact on political processes. It will be argued that, if certain conditions are fulfilled, AI-facilitated digital tools could help with setting up frameworks for bottom-up citizen participation that could generate the legitimacy and popular buy-in required for speedy transformations needed to reach net zero such as radically revamping the energy infrastructure among other crucial elements of the green transition. This could help with ameliorating a potential dilemma of voice versus speed regarding the green transition. The article will further address the nexus between digital applications such as AI and climate justice. Finally, the article will consider whether innovative governance methods could instil new dynamism into the multi-level global climate regime, such as by facilitating interlinkages and integration between different levels. Before implementing innovative governance arrangements, it is crucial to assess whether they do not exacerbate old or even generate new inequalities of access and participation.

The scaling of urban climate action and its governance is rapidly becoming a central focus in the urban climate governance literature and policy debates. Building on the broader scaling literature and inspired by related initiatives in other fields, this article calls for the development of a systematic “science of scaling” for urban climate governance. Such a science of scaling may help to give a better understanding of how well-performing urban climate action and its governance can be multiplied, accelerated and broadened (ie horizontal and vertical scaling and scaling out, up and down), and it may help to uncover scaling trajectories towards systemic change in cities (ie deep scaling).

Rome is a complex metropolis. The city faces the challenge of imagining and shaping an inclusive and sustainable future for its inhabitants. On several occasions, city policies and interventions have not met the goal of preserving environmental resources. For their part, the inhabitants of Rome tend to doubt the ability of institutions to take care of the city’s resources. We focus on civic environmental monitoring led by the local independent association A Sud, aimed at assessing the environmental status of two of the city’s rivers. From a review of applicable literature on governance, environmental and social justice and climate urbanism, we build a theoretical frame to guide our analysis. We inquire how civic monitoring in a complex city can benefit urban resource governance and foster urban transitions. We also explore the extent to which these initiatives have the potential to inform or have actually informed the scientists and policymakers responsible for designing city adaptations. Our analysis demonstrates that citizen-gathered data can enrich the scientific knowledge base and trigger claims for interventions, bringing in information on local issues often overlooked by competent institutions. The initiatives also improved individual and collective attitudes towards the city and its resources, stimulating a sense of care and a watchful citizenship.

Transition intermediaries are expected to play an important role in the acceleration stage of the energy transition. While existing scholarship helps us understand the role of transition intermediaries in the early stages of transitions, it remains unclear what role intermediation plays in subsequent transition stages, especially at the local level where the implementation of policies and legislation takes place. In this article, we aim to investigate how intermediation takes shape in the acceleration stage of the energy transition. Drawing on the literature on transition intermediaries and intermediation at the local level, we explore the role of transition intermediaries in two local energy projects in the Netherlands. Through extensive qualitative research, we find that various actors can act as transition intermediaries and that a single actor can fulfil different intermediary roles simultaneously. Our findings contribute to the literature on transition intermediation and urban intermediaries, emphasising the key role intermediaries play in aligning innovations with existing institutional configurations. Furthermore, we highlight their role in connecting the energy transition to broader societal developments, including through citizen involvement in local and regional governance arrangements.

Climate adaptation planning in pursuit of resilient and sustainable societies has become a focal point in urban policy. Climate adaptation planning is generally regarded as separate from traditional urban planning practices. Globally and in Europe, however, cities are increasingly integrating climate adaptation planning into their traditional urban planning instruments and processes. Recent research indicates that the scope of such integration is at varying stages. The City of Rotterdam (Netherlands) and the City of Antwerp (Belgium) have been identified as two European cities that face similar climate impacts and risks given their proximity to a large river delta. Both cities aim to integrate climate adaptation into their respective urban planning policies, but the scope of their integration differs. This paper critically analyses the urban planning policies of these two cities to distil key lessons learnt that cities with similar climate impacts and approaches to urban planning may potentially face in integrating climate adaptation planning into urban planning policies. The paper finds that identifying and evaluating the synergies, co-benefits or trade-offs of adaptation measures is a key challenge to integrating climate adaptation into urban planning policy. It is a potential stumbling block for long-term sustainable development and climate resilience.

Given the state of the climate emergency, European Union (EU) cities must find innovative ways to achieve a sustainable and decarbonised urban mobility trajectory. This requires integrated and cross-sectoral approaches that enable all sectors influencing such mobility to contribute to this goal. Building on the concept of the climate-connected city and drawing on an extensive empirical investigation of two Dutch cities (Rotterdam and Maastricht), this study reflects on how decarbonisation targets are integrated with other sustainability objectives across all policies and levels involved in reconfiguring mobility towards an environmentally sustainable model. The study finds that spatial development tools and processes, in combination with regulatory instruments imposing strict limits on emissions, can strengthen cross-sectoral support for the behavioural changes needed to decarbonise urban mobility. However, this integrative dynamic may be countered by local economic actors and by national and EU economic and fiscal instruments, whose narrow focus on reducing vehicle emissions and expanding road capacity forces cities to dilute their sustainable mobility policies. This suggests that in order to accelerate the decarbonisation of urban mobility, these instruments should be aligned with a broader set of sustainability goals and solutions and be combined with greater attention being given to the urban dimension into national and European transport policies.

This piece addresses Case C-458/19 P before the Court of Justice of the European Union (CJEU) concerning a substance of long-term exposure, namely bis(2-ethylhexyl) phthalate (DEHP). The case concerned the interplay of two complex procedures of European chemical law, namely: the procedure for authorising the use of a substance listed in Annex XIV of Regulation (EC) No 1907/2006 (REACH Regulation); and the procedure for listing a substance in Annex XIV of the REACH Regulation on the basis of its intrinsic properties as a substance of very high concern for the risks it poses, or may pose, to human and environmental health. The significance of this judgment is that it provides a better understanding of how Article 60(4) of the REACH Regulation is interpreted in an analogous manner in relation to other provisions of the same Regulation. Whether DEHP is a question of reproductive toxicity (Article 57(c) of the REACH Regulation) or endocrine-disrupting properties (Article 57(f) of the REACH Regulation), this judgment offers insights into the limits of the CJEU’s willingness and/or ability to use a teleological approach to interpret legislation in this area. Furthermore, this work supports the possibility of applying the principle of intergenerational equity to issues related to long-term exposure such as this one.
