The current public transport offers in the South Baltic region seldom meet customer expectations for easiness and attractivity of cross-border/regional journeys and rarely include integrated tickets for multimodal rides. To address that, stakeholders from six regions around the southern Baltic Sea developed the INTERCONNECT project that was guided by a holistic perspective on sustainability. Informed by that, this paper's objective was to propose a tool/method containing a planning process with a comprehensive and on-line open-access catalogue of solutions for sustainable cross-border/regional public transport services to inspire and guide planning and decision-making. The tool/method that was developed in this paper include a 7-step process and a catalogue of 42 solutions that were developed through several workshops and discussions among the authors and other experts in the field. The findings were compared and integrated with literature findings, practical experiences, then assessed against a principled definition of sustainability, and finally scrutinized and reviewed by project partners and external experts. The authors expect the results to sufficiently cover possible solutions for strategic sustainable development of cross-border/regional public transport and to inspire further development in other regions with similar infrastructure and financial means. © 2021 Owner/Author.

The study was conducted in 2020 by The SustainTrans team at Blekinge Institute of Technology with support fromNetPort Science park as a pre-study within the Roadmapper project, an effort to accelerate regional transitions to sustainable transport.This particular pre-study was financed by the municipalities of Karlshamn, Olofström and Sölvesborgbut it also benefits the larger Roadmapper project that, in turn, is supported by a whole consortium of public and private organizations, led by the Swedish Energy Agency. The preliminary resultswere reported to themunicipalitiesin December 2020but thescientific review of the studywas finalized in March2021. 

Electric buses are growing in numbers in Sweden, which contributes to the development of a fossil fuel free society and a reduction of emissions. Earlier studies of bus systems have identified a need to further investigate societal costs, total cost of ownership, energy use on a yearly basis to account for seasonal variations, and noise during acceleration. Addressing those needs was the purpose of this study. 

Investigations were made in five cities in Sweden that have recently implemented different electric buses in their respective public transport system. Based on results from these investigations and earlier studies, updated and new calculations were made for electric buses on route 1 in Karlskrona, as a representative example. It was found that there were significant savings in societal costs and total cost of ownership when compared to diesel and biogas powered buses, mainly due to decreased noise, no emissions in the use phase, and decreased energy use.

This paper presents a case study of a transdisciplinary scenario planning workshop that was designed to link global challenges to local governance. The workshop was held to improve stakeholder integration and explore scenarios for a regional planning project (to 2050) in Blekinge, Sweden. Scenario planning and transdisciplinary practices are often disregarded by practitioners due to the perception of onerous resource requirements, however, this paper describes a ‘rapid scenario planning’ process that was designed to be agile and time-efficient, requiring the 43 participants from 13 stakeholder organizations to gather only for one day. The process was designed to create an environment whereby stakeholders could learn from, and with, each other and use their expert knowledge to inform the scenario process. The Framework for Strategic Sustainable Development (FSSD) was used to structure and focus the scenario planning exercise and its subsequent recommendations. The process was evaluated through a workshop participant survey and post-workshop evaluative interview with the regional government project manager to indicate the effectiveness of the approach. The paper closes with a summary of findings which will support those wishing to conduct similar rapid scenario planning exercises to inform policy planning for complex systems.

Without experiences of electric buses, public transport authorities and bus operators have faced questions about how to implement them in a cost-effective way. Simple cost modelling cannot show how costs for different types of electric buses differ between different routes and timetables. Tools (e.g., HASTUS, PtMS, and optibus) which can analyse such details are complicated, time consuming to use, and provide insufficient insights into the mechanisms that influence the cost. This paper therefore proposes a method for how to calculate total cost of ownership, for different types of electric buses, in a way which can predict how the cost varies based on route and timetable. The method excludes factors which cause minor cost variations in an almost random manor, in order to better show the fundamental mechanisms influencing different costs. The method will help in finding ways to reduce the cost and help to define a few cases which deserve a deep analysis with more complete tools. Testing of the method in a Swedish context showed that the results are in line with other theoretical and practical studies, and how the total cost of ownership can vary depending on the variables.

Medan Sverige är en global föregångare inom hållbar utveckling betonar Klimatpolitiska rådet 2019 att hållbarhetsåtgärderna är för långsamma för att uppfylla de aktuella målen, särskilt när det gäller transport och stadsmiljö. Regional utveckling och kommunal fysisk planering spelar avgörande roller i förändringsprocessen eftersom planerare och strateger behöver ta itu med internationella avtal såsom Parisavtalet, Agenda 2030 och Den nya urbana agendan, samt svara på nationella mål och lokala prioriteringar. Det finns indikationer på att otillräcklig samordning mellan de nationella, regionala och lokala planeringsinsatserna är en nyckelfaktor bakom misslyckandet med att hålla sig på rätt spår. För att hjälpa till att hantera denna brist engagerade planerare från Region Blekinge i sydöstra Sverige SustainTrans-gruppen från Institutionen för Strategisk hållbar utveckling vid Blekinge Tekniska Högskola för att bana väg för en scenarioplaneringsstrategi över en 30-årig horisont (till 2050). Tanken var att ta fram åtminstone tre scenarier och att få med regionala, lokala och några relevanta nationella intressenter i genomförandet. Som ett minimum skulle de fyra identifierade nyckelområdena från projektet Strukturbild Blekinge 2.0 täckas in i studien:

Blekinges övergripande utveckling (exempelvis befolkningsutveckling)Arbetsmarknad, näringsliv och turismAttraktiva stads- och livsmiljöerInfrastruktur och transport

Rapportförfattarna från SustainTrans-gruppen arbetade iterativt med befintliga kunskaper, statistiska data och resultat från en intressent-workshop. Ett startläge identifierades och fyra utforskande scenarier togs fram och strukturerades efter de sannolika effekterna av höga och låga regionala hållbarhetsinsatser respektive hög och låg befolkningstillväxt: 

’Tveksamma Blekinge’ (oförändrad befolkning/ ej hållbart)’Blind tillväxt’ (ökad befolkning / ej hållbart)’Hållbarare Blekinge’ (oförändrad befolkning/ hållbart)’Nystart Blekinge’ (ökad befolkning/ hållbart)

Scenarioprocessen inkluderade alla nyckelområdena från Strukturbild Blekinge 2.0 som viktiga utvecklingsområden och resulterade i bredare samtal mellan offentliga intressenter. Detta kommer också förhoppningsvis lägga en grund för ökad samordning och integration mellan dessa organisationer.

Baserat på intressenternas synpunkter på scenarierna från workshopen, blev rapportförfattarnas bedömning att scenarierna ’Tveksamma Blekinge’ och ’Blind tillväxt’ skulle få för många negativa konsekvenser. Detta kunde ju också förväntas med tanke på scenariernas namn men mer specifikt handlade det om att det förstnämnda scenariot ge en gradvis nedgång medan det senare på sikt ge verkligt destruktiva resultat för livskvaliteten, naturen och samhällsekonomin. ’Hållbarare Blekinge’ och ’Nystart Blekinge’ bedömdes å andra sidan vara bättre eftersom de troligen skulle säkerställa en god livskvalitet. Med det senare scenariot kan den högre folkmängden sannolikt också ge extra fördelar som högre skatteinkomster och en mer välmående region. Det finns dock en risk att befolkningsökningen kan hämma hållbarhetsprestanda om den skulle drivas för långt.

En åtgärd som identifierades som avgörande för att slå in på spåret till något av de föredragna scenarierna var att stärka planeringsfokus för nya bostäder till täta blandade samhällen inom det befintliga urbana fotavtrycket. Det finns samtidigt regionala gränser för tillväxt som är svåra att uppskatta med den begränsade typen av kvalitativa bedömningar som denna studie skulle täcka. Därför rekommenderas att fler studier görs som bygger vidare på scenarierna, går in i mer detaljerad kvantitativ modellering och bygger färdplaner för ett attraktivt och hållbart Blekinge 2050.

Earlier studies have mainly focused on technology, economy and advantages of electric buses, and they have largely shown that electric buses could be one of the solutions for sustainable public transport. Despite this, the present procurement process for public transport in Sweden is not suitable for including support systems for electric buses. This study was aimed to find a stakeholder collaboration model that would allow electric bus systems to be more effectively included in the procurement process for public transport. The results were achieved by several multi-stakeholder collaboration seminars and meetings that included representatives from regional public transport authorities, bus operators, bus manufacturers, energy companies, municipalities, and experts involved in bus transport. The study primarily developed two stakeholder collaboration models, suggesting that charging infrastructure should be designed separately from the common procurement process. In these models, energy companies, electric grid owners, charging infrastructure operators, regional public transport authorities, and municipalities need to collaborate. The first model is designed for a system that includes chargers at certain locations along a route and/or stakeholders with a low level of experience of electric bus systems, while the second is designed for a system that includes bus charging at the depot and/or stakeholders with a high level of experience of electric bus systems.

Each year at the Blekinge Institute of Technology, in total 15-30 international master students from the Structural Dynamics and the Erasmus program take a 7.5 credit course in strategic sustainable development. In 2016, the course had rather good scoresfrom the students’ course evaluation, but the students also identified a need for improvements regarding feedback from teachers during the course and also regarding the examination of the course. A study was therefore initiated, aimed at finding out if changes in feedback and examinations can increase students’ learning towards the learning outcomes in the course, and if so, how the teaching and examination in the course could be developed in such direction. The study found through literature review, interviews among colleagues, and surveys among students that instead of a final exam, several knowledge tests and reflective questions during the course could increase the students’ learning. The course design was developed and then implemented in 2017. According to the students’ course evaluation the same year, this lead to even better perceived learning. Except from providing further evidence that students’ learning increases with individual feedback, the study showed how that can be implemented.

The aim of this thesis was to explore if, and then how, electric cars and buses can contribute to sustainable personal mobility. Electric vehicles have increasingly been seen as a potential sustainable solution for the transport sector due to their high energy efficiency, close to zero emissions in the use phase, and the possibility to be powered by electricity from renewable resources. However, there are concerns about future scarcity of resources (e.g. lithium and cobalt for batteries), vehicle range, costs, high energy use in the production of batteries, as well as insufficient scientific support for how electric vehicles could be a part of a transition towards sustainability regarding personal mobility.  

The challenges for a fast transition towards sustainability are large and many. The transport sector is not contributing to such development, mainly due to emissions, use of fossil energy, and use of materials mined and recycled under unacceptable conditions. Furthermore, existing societal goals (e.g. fossil-fuel independent vehicle fleet by 2030 in Sweden, UN Agenda 2030, and the Paris agreement) are insufficient for sustainability and are not complemented by concrete plans or an approach for how to engage stakeholders and achieve coordinated actions for sustainability. The Framework for Strategic Sustainable Development includes a principled definition of sustainability that is necessary and sufficient for sustainability and procedural support for collaborative innovation for a strategic transition to fulfillment of that definition, which is why it has been used as an overarching methodology in this thesis. 

The research verified through several studies conditions for how electric vehicles can play a vital role in a strategic transition of personal mobility towards sustainability. Through stakeholder collaboration (e.g. interviews and workshops), a vision for sustainable transport with a focus on electric vehicles and an initial development plan towards that vision were designed. Several life cycle focused studies investigated (through calculations and data collection from literature, life cycle databases, interviews and workshops) about environmental and social impacts and costs for electric cars and buses. The stakeholder collaboration, combined with conceptual modelling, also resulted in models for generic support for multi-stakeholder collaboration and planning for strategic sustainable development of transport systems and communities, and for how to include electric buses in the procurement model of public transport.

The strategic sustainable development perspective of this thesis broadens the analysis beyond the more common focus on climate change issues and should be able to reduce the risk of sub-optimizations in community and transport system development when applied in that context. The generic support for multi-stakeholder collaboration could potentially also promote a more participatory democratic approach to community development, grounded in a scientific foundation.

Electric vehicles seem to offer a great potential for sustainable transport development. The Swedish pioneer project GreenCharge Southeast is designed as a cooperative action research approach that aims to explore a roadmap for a fossil-free transport system by 2030 with a focus on electric vehicles. It is the following combination of objectives that puts demand on a new process model adapted for cross-sector and cross-disciplinary cooperation: (i) a fossil-free transport system in Sweden by 2030 and, to avoid sub-optimizations in the transport sector, (ii) assuring that solutions that support (i) also serve other aspects of sustainability in the transport sector and, to avoid that sustainable solutions in the transport sector block sustainable solutions in other sectors, (iii) assuring cohesive creativity across sectors and groups of experts and stakeholders. The new process model was applied in an action-research mode for the exploration of electric vehicles within a fully sustainable transport system to test the functionality of the model in support of its development. To deliver on the above combination of objectives, a framework was needed with principles for sustainability that are universal for any sector as boundary conditions for redesign, and with guidelines for how any organization or sector can create economically feasible step- by-step transition plans. The Framework for Strategic Sustainable Development (FSSD) is designed to serve such purposes and therefore is embedded into the new process model. The exploration of this new model also helped to identify four interdependent planning perspectives (‘Resource base’, ‘Spatial’, ‘Technical’ and ‘Governance’) that should be represented by the respective experts and stakeholders using the model. In general, the new process model proved helpful by giving diverse stakeholders with various competences and representing various planning perspectives a common, robust, and easy-to- understand goal and a way of working that was adequate for each of their contexts. Furthermore, the evolving process model likely is relevant and useful not only for transport planning and electric vehicles, but for any other societal sector as well and thus for sustainable community planning in general.
