Abstract

Mobility services and accessibility services could contribute to reduced car-dependency and a more sustainable transport system. However, uncertainty remains regarding what the effects will be and further research is needed.

In this paper we examine potential effects on passenger car-travel in an urban context. To do so, we actuate the Avoid-Shift-Improve (ASI) framework using a System Dynamics approach and develop thematic Causal Loop Diagrams. We draw on the findings from a literature study and workshops engaging actors involved in creating visions and planning for the future of mobility and accessibility services in Stockholm, Sweden. The effects discovered are categorized as direct, enabling and structural/systemic, using a retrofitted version of the Three-Levels Model.

Contributions include the mapping of mechanisms through which the services can have positive and negative effects in relation to ASI, demonstrating a high degree of interconnectedness. This includes potential synergetic and competitive relations between the services. In addition, the approach gives insight to potential cumulative impact of the services, relatable to Mobility as a Service, including ‘user near’ effects regarding, e.g., commuting and leisure travel, as well as systemic and structural level effects. A discussion is conducted on the implications for actors and policy-makers.

To Durham by train

Text by Nina Wormbs

I received an invitation to go to Durham university to speak at a conference and engage with PhD students. I immediately considered it, but I also let my host know that having me over would probably cost more, as taking the train is more costly these days. And I like to take the train. The offer remained and I said yes.

Come spring and planning, I postponed this for too long. Perhaps due to the war, perhaps because of workload. It worked fine in the end, but in hindsight I would most likely have chosen a slightly different route back home.

Stockholm – Durham is rather long. I discarded ferries early on since I now know – through an earlier mistake – know that they are not good from a CO2 perspective. I also decided not to sleep on the train. The reason was mainly Covid and the lack of flexibility if you want to have your own compartment. Thus I was left with travelling during the day and stopping on the way. Since I have family in Lund, that was a natural place for my first night.

That allowed me to make an early start on the travel across Germany for Köln. The trip had four legs: I changed trains in Copenhagen, Fredericia and Hamburg. This went smooth and without incidents. I arrived in Köln and had time for a long walk in the city and then dinner with a friend who also hosted me for the night. Great stop.

Next day I took the high-speed train to Brussels and then the Eurostar to London St Pancras. This gave me ample time in the afternoon and night in London and also the possibility for a long walk the next morning. Lovely as they say.

The train for Durham left from King’s Cross which is next to St Pancras. This train was also without incident and I arrived less than three hours later in a magnificent city. The river Wear makes a loop around a hill on which the old town with its castle and world heritage cathedral is built. It is to a high degree a university town, with most of the campus south of the inner city.

The conference and PhD spring school lasted four days and I left on the fifth. When I got around to make reservations, options were few due to Easter, and I ended up taking the Eurostar to Paris. That was a late train to start with, which also became delayed. Still, I managed to walk around and smell Paris before I went to sleep in a tiny little room on La Fayette.

Easter Saturday started with a high-speed train to Köln via Brussels. No worries. In Köln I had time to buy lunch and walk a bit around the cathedral which is just outside of the station. However, the train to Hamburg turned out to be delayed and I could have missed my connection. The train waited, however, which was a relief. Normally the trip between Copenhagen and Lund is effortless, but during Easter construction work was undertaken and I had to take the bus between the airport and Hyllie. In the end it did not take longer actually, but was slightly more inconvenient. I was rather tired when I put my head on the pillow, after that 15 hour journey. I stayed on in Lund and eventually managed the last leg to Stockholm.

With this many trips, an interrail mobile pass is the cheapest option. The app mostly worked well and a mobile pass is really useful as it also has search functions, Q&A, community and is flexible. I made reservations on all trains, also those where I did not need to.

Stockholm – Durham can perhaps be done in two days. But it would be tough and you are vulnerable to delays. I only had two delays and only one was serious. With more travel days the risk diminishes of unexpected major changes to your itinerary.

And mobility becomes more travel and less transport.

A multi-criteria analysis of building level graywater reuse for personal hygiene – new article co-authored by Timos Karpouzoglou

Timos Karpouzoglou has been with the Division since 2018, and is working closely with the KTH WaterCentre, where he previously was a research coordinator. His current research is focused on urban water infrastructure and is informed by social sciences and the humanities. In a new article, together with Jörgen Wallin (KTH) and Jesper Knutsson (Chalmers), Timos investigates how water demand globally exceeds over available water supply, and takes a closer look at the reuse of bathroom graywater for shower and bathroom sink hot water. The investigation focuses on water and energy savings, water treatment, economic benefit and investigates the main actors and institutions that are involved. “A multi-criteria analysis of building level graywater reuse for personal hygiene” was published in the 2021 December issue of Resources, Conservation & Recycling Advances.

Abstract

Globally an increasing number of people are facing water scarcity. To address the challenge, measures to reduce water demand are investigated in the world. In the present paper, a novel approach to reuse bathroom graywater for shower and bathroom sink hot water is investigated. The investigation focuses on water and energy savings, water treatment, economic benefit and investigates the main actors and institutions that are involved.

The main results are that there is significant potential for water and energy savings with a positive economic benefit. Water savings of domestic hot water up to 91 % and energy savings up to 55 % were observed. The investigated treatment plant produces recycled graywater with a quality close to drinking water standards.

The investigation also presents that the reason for the positive economic benefit will depend on the utility tariffs. Therefore, two locations with different utility rate structures were investigated, Gothenburg, Sweden and Settle, USA. In Gothenburg, the utility cost for energy was the driver of economic benefit and in Seattle it was the water and wastewater cost that was the driver. The return of investment for the system and installation was shown to be 3.7 years in Gothenburg and 2.4 years in Seattle.

Beyond Unprepared and Sustainability’s Formative Moment – Formas’ Grants Two New Projects

Division researchers Fredrik Bertilsson and Eric Paglia recieved funding for four years each in the Formas Annual Open Call 2021 – Research projects for early-career researchers. In 2022 the Division looks forward to two new projects: one on humanistic expertice and knowledge and one that question the earlier periodization of the sustainability narrative.

Summary Beyond “unprepared”: Towards an integrative expertise of drought

Profilbild av Fredrik Bertilsson

The overarching hypothesis of this project is that the understanding of preparedness is fundamentally transformed in the era of Anthropocene. In Sweden, recent events such as the corona pandemic and the extreme weather in 2018 have pointed out insufficiencies in public readiness. This project explores drought in Sweden, which until recently was a marginal problem on the national agenda but is now a priority of the Swedish government. Both public agents and researchers call for collaboration an “integrative expertise” that combine the expert knowledge of natural sciences, social science and the humanities to advance public preparedness. However, the potential of humanistic expertise and knowledge is under-researched. The potential of humanistic knowledge becomes relevant in new contexts where problems and potential solutions fall outside the domain of previously dominating expertise. The aim of this project is to contribute to the expertise for increasing public preparedness. The purpose of the project is to study: the identification of Swedish “unpreparedness” in relation to the drought in Sweden in 2018, the historical processes behind this present unpreparedness, and the formation of future experts focusing on the significance of humanistic expertise. The project provides a novel and timely assessment of integrative expertise of drought. It engages with actors in the public sector, NGOs, academic research, and arts and culture

Summary Sustainability’s Formative Moment: The Birth of the Boundaries Narrative and the Rise of the ‘Human Environment’

Profile picture of Eric Paglia

This project examines the emergence of the “Boundaries narrative” between 1968-1974 in connection with the 1972 UN Conference on the Human Environment. “The environment” as a problem was well known, but in 1968 there were no international political institutions for managing it. Neither developing countries nor the business community had an interest in imposing restrictions for the environment’s sake. In this struggle between scientifically and ideologically motivated demands for restraint, and economically and politically motivated demands for continued expansion, the idea emerged that growth and environment could be reconciled—what would later be called sustainable development. We will study in detail the interplay of different expert cultures, from governments via constellations of scientists, to smaller groups that could include executives, researchers, diplomats, activists, economists and others. We are particularly interested in three key individuals and their networks: Canadian businessman Maurice Strong, economist Barbara Ward and MIT management professor Carroll Wilson. We will both question the earlier periodization of the sustainability narrative, and develop a new understanding of its scientific and political basis. The project is of potentially great importance for the narrative’s legitimacy in a time of mounting conspiracy theories, when the world could at the same time be on a path towards decisive transformation through the implementation of Agenda 2030.

”Två fel gör inte ett rätt” – How China is taken as an argument to not act for the climate

Nina Wormbs, Professor of History of Technology at the division, has published an article relevant in the context of the recent COP26 climate summit in Glasgow in the daily newspaper Dagens Nyheter on 17 November 2021. In the following we will present a short summary of its main points in English, while you can read the original in full length and in Swedish here.

Summary:

When climate issues are discussed in Sweden, China is often taken as a comparison. In fact, people use China as an argument to not act in regard to climate change.

During the recent COP26 summit in Glasgow, the focus was also on China, since the country is highly invested in coal both at home and abroad. It is obvious that we need to work with China together, since its emissions are enormous. Despite this, China has recently undertaken steps towards a sustainable society.

In particular, it has become normal to point to China in a debate, if one does not want to engage with those questions the current climate crisis is bringing up. This can include coal power plants but also a justification for flying to Mallorca or Thailand for fun, because Chinese tourists could be seen in Gamla Stan. In order for this practice not to spread further, we have to understand why those arguments are not valid and what they result in.

First, it makes no sense to motivate one’s own harm-doing by arguing that someone else would produce even more harm.

Secondly, the comparison with China’s emissions are an eternal but nevertheless problematic way of relativising one’s own influence. Because you are always able to find someone who produces more emissions than yourself. More than Sweden. More than Europe. Of course it is important how much we emit as humanity, but the China-argument suggests that there would be some form of give- and take, like as if life would be a zero-sum-game. Instead, it is the opposite: every ton of CO2 counts.

Additionally, the China-argument points to an understanding, in which one does not have to do a tiny bit of right, while someone else does so much wrong. Maybe this argument is spreading, because more and more people repeat it. People in Sweden have limited knowledge of China. China is bigger, has more people, and all of them are striving towards a better life. That’s why it might be easy to point to China, in order to relativise one’s own responsibility.

Thirdly, China is often portrayed as an enemy in Swedish media. It can therefore be seen as a nation different from Sweden, being imagined like the negative “other”.

Why are the USA never mentioned in this context, despite their higher historical and per-capita-emissions (IPCC and carbonbrief.org)? Qatar, Kuwait and the United Arab Emirates are also hardly ever named, even though they are leading the per-capita-emissions statistics.

If one looks into the emissions of production chains of consumer goods, of which a lot are produced in China but used somewhere else like in Sweden, the territorial basis for emission-calculations seems off.

Furthermore, within most individual nations the gap between rich and poor gets bigger, which means that the individual emissions are not what the average suggests, but rather high if you are rich, or low if you are poor. Therefore, it would be a great idea to change the focus from nations to individuals, like Chancel and Piketty suggested in 2015.  This makes even more sense, since the richest 10% of the world’s population accounted for 50% of emissions since 1990. Those 10% can be found in every country, but they are not evenly distributed. More so, since 40% of those live in the USA, while only 10% live in China. It might be a cold shower for a Swedish discussant that every Swede with a monthly income of over 27,500 SEK belongs to this group.

This is not being written to support China’s climate policies. Instead, it is to show that China is not relevant if one wants to discuss a domestic climate action plan, as the relationship between being rich and producing lots of emissions is evident – and Sweden is one of the richest countries on earth.

Film launch: Resource Extraction and Sustainable Arctic Communities – REXSAC

REXSAC – Resource Extraction and Sustainable Arctic Communities – is a Nordic Centre of Excellence in Arctic research, funded by Nordforsk and led by the Division, together with Stockholm University and Stockholm Environment Institute. Representants in REXSAC from the Division are researcher and LTU Professor Dag Avango, Professor Sverker Sörlin and doctoral students Jean-Sébastien Boutet and Camilla Winqvist. Today the new REXSAC film was launched.
The film “Resource Extraction and Sustainable Arctic Communities” with results and conclusions from the work in REXSAC is availabe and open access. The film highlights how mineral extraction systems combined with other societal activities and climate change exert pressures on Arctic ecosystems & local- and traditional livelihoods. Follow the link to the REXSAC blog below, to read more about why and how the film was made, and also to watch it.

Discussing the issue of flying and sustainability

By Nina Wormbs

The week before Christmas, a number of colleagues at the Division gathered for a workshop where we discussed flying habits. It was part of the research project Decreased CO2-emissions in flight-intensive organisations: from data to practice at the EECS school, KTH Royal Institute of Technology, led by Daniel Pargman with funding from the Swedish Energy Agency. Elina Eriksson led the workshop with support from Daniel and Aksel Bjørn-Hansen.

The aim of the project is to see how we might reduce the carbon footprint of KTH that stems from flying. Since flying is a large part of KTH emissions and totally dominates those of travel, it could be seen as low hanging fruit. At the same time, travel is nowadays also part and parcel of academic culture. Thus, there are interesting obstacles to change behaviour.

Academic flying has interested us at the Division for many years and as a response to a discussion at our kick-off in 2015, the blog The travelling scientist was launched and Johan Gärdebo had a small project with workshops of similar kind.

In the workshop we received information on our flight patterns, data that the project has collected after great work. It was not easy for Pargman and his colleagues to get a full picture of the flying at KTH, and not even now do they know for certain the sources of KTH flying emissions. This data is of course crucial since the government has required that public agencies work with their emissions. And if we do not have data, we cannot report and reduce.

It turned out that flying at our Division, perhaps not so surprisingly, was not evenly distributed among our colleagues for the year 2019. Of 47 employees, 12 did not fly at all, whereas some made about a dozen flights. Moreover, the type of flights varied, and this is particularly interesting since the focus is CO2 emissions. Based on our division’s data a medium-range flight to Europe emits 3,4 times as much as a Scandinavian flight. And an intercontinental flight emits 20 times as much. Not surprisingly, Division emissions from intercontinental flights make up almost 80 percent. (See figure below.)

In the workshop we were encouraged to think about travelling and if and how to change it. This we did in small groups (everything on zoom of course) and with feedback through Menti. The first question regarded what flights could be avoided and common suggestions were intercontinental ones, very brief conference trips and those of committee work. On the other hand, field trips and archival work was hard to avoid.

This was most likely connected also to the insights of the pandemic, where we have realised that some things can indeed be done differently. The second question in the workshop focused on precisely this: what did we learn from the pandemic that we can use in the future. Here answers varied from the longing for real meetings with colleagues to realising that many meetings work fine digitally. Some digital conferences that we have experienced also shows that this was of meeting can be more inclusive.

About a dozen people joined the workshop, and hopefully it can still help the Division in contributing to a constructive change. KTH has environmental and emission targets and if we do not want to see hard regulation from above, we need to work from below. The workshop participants were in agreement that we have a responsibility to reach the climate objectives and most also believed that flying less is possible.

Experiences in Digital Teaching

Covid-19 has profoundly changed the way we work as scholars of the humanities. Teaching is no exception to this. The digitisation of university education was abruptly maximised and teachers were to a big extent forced to adapt to the new reality of online teaching on their own.

Kati Lindström has written about her experiences during the autumn term. She is a researcher with a lot of know-how both in teaching in general and in digital education in particular. In her opinion, the systems we use can be majorly improved. Canvas as a teaching platform is limited under these new conditions and needs a drastic makeover or at least generous supplementation to make education more efficient. As a result of inefficient software, teachers need to spend a lot of time on tedious clicking-work, which easily could be made obsolete. During the last term, this got out of hand.

The stress, which is put upon teachers, manifests in different forms. For Kati, it took the form of severe arm pain, which under the given circumstances is hard to mitigate. Therefore, the question needs to be asked:

A computer mouse, being used by a hand. A keyboard, pen, headphones and a mug are standing left of it. The picture is kept in black and white.

What can we improve in the field of digital education during the upcoming terms?

In the face of the surging Covid-19 pandemic, we will most likely not be able to go back to normal any time soon. So if we have to do online teaching to this extent for the foreseeable future, it should be in the interest of everyone to enable the conduction of education within the boundaries of (professional) sustainability.

Sustainable communities and heritage politics beyond nature-culture divide – funding from Formas

Formas granted the divisions Kati Lindström funding for the project Sustainable communities and heritage politics beyond nature-culture divide: Heritage development as a strategy against depopulation in Japan. The project will start next year and run until the end of year 2020.

The aim is to analyse the use of heritage development as a possible strategy against depopulation, by comparing how different types of heritage relate to the local communities. Governments often see heritage development as a means for the depopulating communities to acquire a more stable economic footing. While there is sufficient proof that especially world heritage nomination has brought an economic boost to many locations, there is also evidence that this is not necessarily a guaranteed long-term strategy. However, there is no clear understanding which heritage types function best in case of depopulation and how does depopulation influence the maintenance of heritage in the long run.

The project carries out qualitative analyses of 7 heritage nominations from four different categories (cultural landscape, natural, industrial and archaeological heritage) in Japan and asks which of the four types benefits the related communities best (economically, socially,culturally), how they are impacted by depopulation and changing community structures and how do local governments envision heritage maintenance with reduced population. It is expected that the results of the study serve as reference to heritage developers in depopulating communities worldwide. The study will be carried out from the perspective of environmental humanities, using various methods and sources from macroeconomic data to stakeholder interviews, participant observation, focus groups, media and site analyses.
