Abstract [en]

Global textile production and consumption has increased steadily over the past 15 years, which has caused significant impacts on the climate and the environment. In 2022, the EU launched a strategy for sustainable and circular textiles, stating that extending the life of textile products is the most efficient way to reduce their impact on the climate and the environment. Shell jackets for outdoor use are textile products that are frequently discarded by their first users and re-sold on the second-hand market. This study evaluates the performance of 16 second-hand shell jackets from three second-hand stores in Sweden via material testing of four key functional aspects. Comparing the results with the jackets’ original performance, this study describes the change in functionality over time. The results indicate that air permeability does not change significantly, whereas water repellency, water penetration resistance, and breathability decrease over time, although they do so at different rates. With the aim of promoting circularity and encouraging longer product use, this study also compares the price evolution of jackets with their functionality over time. The results reveal that the resale price of the jackets is lower than could be expected based on the level of remaining functionality in the jackets.

Abstract [en]

Food production and consumption significantly contribute to climate change. The public sector, which procures large quantities of food, has a crucial role in steering toward more sustainable food systems. More empirical studies involving practitioners are called for to understand the complexity of sustainable public food procurement. This study examines how actors interpret and implement sustainability in food procurement, as well as their influence on this process. A comprehensive analysis of multi-actor collaboration and stakeholder engagement involving interviews with key actors such as procurement officers, wholesalers, chefs, and food producers is presented. Findings highlight a consensus on the need for sustainability measures, such as purchasing local and organic products. The results showcase the potential transformation of power dynamics within the supply chain in response to modifications in procurement standards toward local produce and the overuse of product-specific criteria. However, assuming that local is invariably sustainable carries the risk of falling into the “local trap” when the consequence of procuring local varies and requires further investigation. The influence of system-level factors, including market dynamics and regulatory frameworks, plays a significant role in implementing sustainable procurement, as well as alignment and coordination in the supply chain.

Abstract [en]

Life cycle assessments of circular economy measures (CE LCA) of consumer products have been criticized for oversimplifying important aspects of the use phase such as user behavior and rebound effects, limiting our understanding of the environmental performance of circular economy measures. This study tests the usefulness of a framework designed to facilitate accounting for such aspects, by applying the framework to a case study of reuse of shell jackets enabled by “premium secondhand” outdoor stores. Methods for collecting use phase data were user surveys and interviews with store managers. Using the framework on this case study generated several novel insights which are interesting in themselves and as inputs to CE LCA. For instance, secondhand shell jackets have a significantly lower frequency of use during their first use span compared to the second and to shell jackets in the linear reference scenario. This implies that reuse in this case does not function as a mere use extension of otherwise similar use phases as is commonly assumed. The generation of such insights, which hitherto have been lacking in CE LCAs, points to the usefulness of the framework as a tool for opening the “black box” of the use phase in CE LCAs to improve understanding of the environmental performance of circular economy measures.

Abstract [en]

Aviation accounts for approximately five percent of global greenhouse gas emissions through the combustion of fossil fuels. This paper analyses the opportunities and challenges of mitigation measures in limiting travel volume, energy and emission intensity to reduce the climate impact of aviation in Sweden. Several measures are in place that aim to reduce the climate impact of the aviation industry, ranging from regulations to technology alternatives to fossil-based jet fuel. These measures face several crosscutting challenges, many of which are of a socio-economic and political nature, and these aspects are often neglected in favour of focusing on technological solutions. The market creation for alternatives to fossil-based jet fuel is a major challenge, as most consumers today have a limited awareness of and willingness to pay for these innovations. Policy measures in place are proven ineffective in incentivising change. An understanding of the industry as a socio-technical system is required. The value of this review is its broader consideration of the pathways to reduce aviation's climate impact, offering new perspectives and pointing to areas for further research considering all components, their interactions and interdependence.

Abstract [en]

Ambitious fossil-free targets imposed on the aviation industry worldwide demand a large volumetric supply of sustainable aviation fuel (SAF) to meet. Sweden's commitment to a 30% volume SAF blending target by 2030 attracts interest in local production. However, the sustainability of local production is largely unknown. Addressing this gap, we aim to explore potential SAF technology pathways and assess their environmental performances in Sweden. To do so, we utilize a socio-technical system (STS) approach for pathways selection and prospective life cycle assessment (LCA) for environmental impact assessment. As a result, we identify two lignocellulosic-based and two electrofuel-based pathways and evaluate their global warming potential, mineral depletion potential, ionizing radiation, land use, freshwater ecotoxicity and human toxicity impact in comparison to jet fuel. Our findings show that the well-to-wake global warming potential (100 years) of 30% SAF is on average 20% lower than that of jet fuel, with non-carbon dioxide species emitted in flight being the major contributors, prompting the need for urgent research efforts to mitigate their potential impacts. Under the assumption that no burdens are allocated to waste material used as feedstock, lignocellulosic-based 100% SAF has a well-to-pump climate impact (100 years) ranging from 0.6 to 1.5 g CO2−eq/MJ compared to jet fuel's 10.5 g CO2−eq/MJ. In contrast, the well-to-pump climate impact (100 years) of electrofuel-based 100% SAF (ranging from 7.8 to 8.2 g CO2−eq/MJ) is only marginally lower than that of jet fuel, mainly attributed to emissions from steel and concrete produced for wind turbine manufacturing. In general, the use of electricity generated by wind power could shift the potential environmental burden associated with jet fuel from global warming to mineral depletion, land use, freshwater ecotoxicity and human toxicity. The STS approach underscores the need to prioritize changes in systems underpinning SAF production, in turn supporting policy and investment decision making.

Abstract [en]

While it may be impossible to accurately predict what the world will look like in the future, we can be certain that it will be different from the world of today. By extension, we know that using today's data in life cycle assessment (LCA) studies claiming to represent future scenarios is problematic. For the future impact of products to be estimated in a consistent and meaningful manner in LCA, the background system, most commonly the ecoinvent database, needs to be projected into the future alongside the foreground system modeled in a given study. Futura is a new piece of open-source software which allows LCA practitioners to create and share novel background databases representing arbitrary scenarios. It allows users to import a base database and then start making targeted changes. These changes take three main forms—adding new technologies, regionalizing new or existing technologies, and altering market compositions. All changes made are automatically added to a "recipe." This recipe file can be shared publicly. This recipe can be imported by other users and used to exactly recreate the modified database. The additive and transparent nature of this system means that initially simple scenarios can be built upon by others to progress toward more comprehensive scenarios in a stepwise manner. The inability to build on the work of others is a serious barrier to the progress of the LCA field. Futura goes some way to reduce this barrier in the field of prospective LCA.

Abstract [en]

Purpose

LCA is increasingly used in infrastructure policy and planning. This study maps approaches used in comparativeLCA of road and rail infrastructure to (1) determine the length of the analysis period, (2) estimate the maintenance frequency,and (3) include the efects of climate change on infrastructure performance. A LCA may need to fulfl diferent requirementsin diferent decision-contexts. The relevance of the approaches for decision-making in policy and procurement is thereforediscussed.

Methods

Ninety-two comparative LCAs of road and rail infrastructure published in peer-reviewed journals January 2016–July 2020 were reviewed. Papers were found through a systematic process of searching electronic databases, applying inclusion criteria, and conducting backward and forward snowballing.

Results and discussion

The analysis period was commonly determined based on infrastructure service life. The maintenancefrequency was estimated based on current practice, laboratory tests, modelling, or scenarios. The efects of climate changewere considered in two papers by comparing results in a control case and in a changed climate. In policy and procurement,current practice approaches are not adapted to innovative solutions or to climate change. Modelling and laboratory tests couldimprove calculations of the maintenance phase but might have some limitations related to innovative solutions. Scenarioscould be readily applied in a policy context; however, in procurement, consistent and generic scenarios should be used.

Conclusions

Results suggest what approaches could be used to account for maintenance in infrastructure LCA dependingon the decision-context. The LCA community is suggested to research other approaches than current practice to account forlong analysis periods, climate change, and innovative solutions. Additionally, literature not covered here could be reviewedfor additional approaches and perspectives. Examples include stand-alone LCAs, method development papers, papers onthe individual approaches and decision-contexts, certifcation systems, standards, and guidelines.

Abstract [sv]

Masshantering (schakt och fyll av jord och berg) kan bidra mycket till ett byggprojekts miljöpåverkan. Masshanteringens miljöpåverkan måste därför beräknas på ett representativt sätt redan i tidig planering. Trafikverket använder verktyget Klimatkalkyl för att beräkna byggprojekts klimatpåverkan och energianvändning. Detta projekt föreslår hur Trafikverket skulle kunna förbättra Klimatkalkyls beräkningar av masshanterings klimatpåverkan och energianvändning i tidiga planeringsskeden. Förslaget baseras på (1) inventering av befintliga livscykelanalys (LCA)-verktyg och en sammanställning av tidigare forskningsresultat, (2) identifiering av vilka aspekter av masshantering som har störst behov av förbättrad indata och (3) identifiering av approacher som skulle kunna göra Klimatkalkyls beräkningar av masshantering mer representativa och analysering av hur Klimatkalkyl skulle behöva ändras för att kunna implementera dessa approacher.

Ett 70-tal LCA-verktyg identifierades genom en litteraturstudie. Det verkar som att verktygen Geokalkyl (från Trafikverket) och Tidligfaseverktøy for bane (från norska Bane NOR) skulle vara de mest relevanta i tidig planering. Denna rapport sammanfattar även resultat från forskningsprojektet Optimass forskning om masstransporter i Sverige. Dessa verktyg och forskningsprojekt ligger till grund för de approacher som utreds i projektet.

Följande aspekter av masshantering verkar ha ett behov av förbättrade schabloner eller en utredning av schablonernas representativitet: krossning, dumper, grävmaskin, lastbil och borrning. Dels bör Trafikverket utreda varför schablondata skiljer sig väsentligt mellan Geokalkyl och Klimatkalkyl, dels önskar entreprenörer tillägg eller förtydligande till Klimatkalkyls befintliga schabloner och dels kan Klimatkalkyls transportavstånd skilja sig väsentligt från faktiskt transportavstånd i byggprojekt. Dessutom bör Trafikverket undersöka om Klimatkalkyl borde inkludera arbetsmomentet vält i byggdelarna Jord Fall A, fyll och Jord Fall B, fyll.

Tre approacher som skulle kunna förbättra Klimatkalkyls beräkningar av masshantering identifierades och analyserades: (1) använda resultat från verktyget Geokalkyl (baserat på geografiska informationssystem) så att projektspecifika schakt- och fyllvolymer kan användas i Klimatkalkyl, (2) utnyttja samband mellan projektets svårighetsgrad och masshantering så att defaultdata kan representera byggprojekts svårighetsgrad och (3) använda region- eller masspecifika transportsträckor för att få mer projektspecifika beräkningar av transportrelaterade utsläpp och energianvändning. Alla dessa approacher skulle kunna förbättra beräkningarnas representativitet, men endast Geokalkyl kan implementeras utan vidare datainsamling.

Den approach som verkade ha störst möjlighet att öka beräkningarnas representativitet var att använda resultat från Geokalkyl. Trafikverket bör därför underlätta överförandet av resultat (m3 schakt och fyll) från Geokalkyl till Klimatkalkyl, vilket bland annat innebär att de två verktygen behöver samordnas så att de innehåller samma typåtgärder och använder samma terminologi.

Att utnyttja samband mellan projektets svårighetsgrad och masshantering bedömdes vara relevant i de byggprojekt som inte använder Geokalkyl. Dock behövs mer arbete för att verifiera samband mellan svårighetsgraden och masshanteringen och ta fram kriterier för olika svårighetsgrader.

Att använda mass- och regionspecifika transportavstånd verkar vara särskilt viktigt för jordschakt. Klimatkalkyls defaultavstånd till och från täkt (30 km) är ett representativt genomsnitt, men för vissa typer av jordschakt kan transportavståndet vara betydligt längre (upp mot 170 km). Dock behöver transportavstånd från fler regioner sammanställas innan nya schabloner kan implementeras i Klimatkalkyl. Klimatkalkyl skulle dock, även utan nya schabloner, kunna uppdateras så att användaren lättare kan lägga in representativa transportavstånd för fall B-massor.

Abstract [en]

As cities worldwide implement strategies to accelerate the transition toward a circular economy (CE), there is an increasing need for tools to monitor progress. However, a standardised metric for CE monitoring in urban areas is lacking. This study examines the potential of the EU Circular Economy Monitoring Framework (CEMF), an established indicator-based framework for measuring national- and EU-level circularity performance, as a monitoring tool for urban areas. For this purpose, available data sources that can support the framework's application at the urban level are mapped, and data quality is assessed following the pedigree matrix approach. Next, the CEMF indicators are computed for the urban area of Umeå, Sweden. The mapping showed limited availability of urban-level data, necessitating the downscaling of national-level data using proxy factors. Most available urban-level data are of high quality, while the quality of national-level data is reduced when used to compute indicators at the urban level. The application of the CEMF in Umeå indicates that there are areas where the municipality performs well, though further improvements are needed. We conclude that the CEMF has potential as a monitoring tool for urban areas. However, improvements in CEMF...s scope and data availability are recommended.
