Summary The idea of a circular economy (CE) has become prominent in both European and Chinese policy making. perspectives on CE share common conceptual basis exhibit many similar concerns seeking to enhance resource efficiency. Yet they also differ, this article explores differences the focus China Europe. We present evidence differing understandings concept discourse, drawing qualitative quantitative analysis documents, media articles, academic publications. show that perspective is broad,...
Abstract Integrated assessment models (IAMs) have emerged as key tools for building and assessing long term climate mitigation scenarios. Due to their central role in the recent IPCC assessments, international policy analyses more generally, high uncertainties related future projections, IAMs been critically assessed by scholars from different fields receiving various critiques ranging adequacy of methods how results are used communicated. Although conceptually diverse evolved very...
China's wide-ranging circular economy (CE) efforts have been studied multiple times from a range of perspectives. Synthesizing the relevant literature, this paper provides critical reflection on transition to CE in China. Key factors for success shifting towards are seen multi-level indicators and upscaling niches. This makes novel contribution limitations progress, based emerging evidence projects that fail sustain. Enriched by experts feedback, critically addresses future challenges deep...
Technology roadmaps are increasingly used by governments to inform and promote technological transitions, such as a transition hydrogen energy system. This paper develops framework for understanding how current roadmapping practice relates emerging theories of the governance systems innovation. In applying this case study roadmaps, finds that transitions needs place greater emphasis on ensuring good quality transparent analytic participatory procedures. To be most useful, should embedded...
Hydrogen remains an important option for long-term decarbonisation of energy and transport systems. However, studying the possible transition paths development prospects a hydrogen system is challenging. The nature technological transitions inevitably means profound uncertainties, diverging perspectives contested priorities. Both modelling approaches narrative storyline scenarios are widely used to explore future energy, but each approach has shortcomings. This paper presents hybrid...
The UK has an extensive natural gas pipeline network supplying 84% of homes. Previous studies decarbonisation pathways using the MARKAL energy system model have concluded that low-pressure networks should be mostly abandoned by 2050, yet most iron pipes near buildings are currently being replaced early for safety reasons. Our study suggests this programme will not lock-in use in long-term. We examine potential future uses improved version introduces a number options including bio-methane,...
The tightened climate mitigation targets of the EU green deal raise an important question: Which strategy should be used to achieve carbon emissions net neutrality? This study explores stakeholder-designed narratives future energy system development within deep decarbonization context. European net-neutrality goals are put under test in a model comparison exercise using state art Energy-Environment-Economy (E3) models: ETM-UCL, PRIMES and REMIND. Results show that while achieving transition...
Energy system models are important tools to guide our understanding of current and future carbon dioxide emissions as well inform strategies for reduction. These offer a vital evidence base that increasingly underpins energy climate policies in many countries. In light this role policy formation, there is growing interest in, demands for, modellers integrate more diverse perspectives on possible preferred futures into the modelling process. The main purpose ensure resultant decisions both...
Abstract This paper explores the role of 'hydrogen economy' as a guiding vision encompassing multiple contested technological futures, value judgements and problem framings. Hydrogen visions draw upon six overarching competing narrative themes: power independence; community empowerment democratisation; ecotopia; hydrogen technical fix; inevitability progress; 'staying in race'. In other words economy possesses great interpretive flexibility. This, it is argued, key to hydrogen's rhetorical...
Hydrogen is widely recognised as an important option for future road transportation, but a widespread infrastructure must be developed if the potential hydrogen to achieved. This paper and related appendices which can downloaded Supplementary material present mixed-integer linear programming model (called SHIPMod) that optimises supply chains scenarios of fuel demand in UK, including spatial arrangement carbon capture storage infrastructure. In addition presenting number improvements on past...
Plastic is valued for its versatility, but concerns have been raised over the environmental impacts of mismanaged plastic waste. A better understanding flows can help to identify areas inefficiency and potential leakage natural systems. This research provides an overview in EU discusses options increase circularity. The study conducted a comprehensive stationary material flow analysis covering 400 categories plastic-containing products with detailed final destination results show relevance...
Achieving the swift energy transition necessary to meet global climate ambitions requires concerted action across governance scales, from municipal authorities national governments. Decision-making is often closely informed by system modelling, making models a crucial tool foster multi-level that based on mutual understanding and coordination scales. Here, we review 186 modelling studies identify challenges opportunities for community take into account facilitate systems. We show current...
