Green distribution options in e-commerce : Display versus content
- 2021
-
Conference paper (other academic/artistic)abstract
- Purpose: Lately, some e-commerce retailers have started displaying climate labels – i.e., eco-labels focusing on greenhouse gas emissions – on distribution or fulfilment alternatives in the check-out of the online store. Using actual purchase data, the purpose of this research is to understand the impact of climate labelling on customers’ choice of fulfillment.Design/methodology/approach: We analyse six months of customer checkout data from a market-leading pharmacy in Northern Europe using a nested logit formulation.Findings: We find that climate labels have a large and significant impact on the probability that a fulfillment alternative is selected by the customer. Further, if the label is attached to a top alternative, it increases the probability that the alternative is chosen. We also find that preselection has a strong effect on the impact of climate labels.Research limitations/implications:We note that climate labelling seems to have a strong impact on customer behavior, it opens up several venues for further research. For instance, there may be other relevant ways to slice the data to bring additional insights. And as climate labelling from more “well-known” labels are being used in e-commerce, the impact might be different.Research limitations/implications: The results have implications for retailers and logistics service providers alike, by indicating both how the content of the fulfillment option and the display of the option in the check-out impacts the business. The results further underline the importance of coordination between retailers and logistics service providers to provide support to consumers.Original/value: Contrary to previous research into greening e-commerce distribution, this paper takes a quantitative approach to address green consumer preferences.

Pulmonary function and atherosclerosis in the general population : causal associations and clinical implications
- 2024

In: European Journal of Epidemiology. - : Springer Nature. - 0393-2990 .- 1573-7284. ; 39:1, s. 35-49

Journal article (peer-reviewed)abstract
- Reduced lung function is associated with cardiovascular mortality, but the relationships with atherosclerosis are unclear. The population-based Swedish CArdioPulmonary BioImage study measured lung function, emphysema, coronary CT angiography, coronary calcium, carotid plaques and ankle-brachial index in 29,593 men and women aged 50–64 years. The results were confirmed using 2-sample Mendelian randomization. Lower lung function and emphysema were associated with more atherosclerosis, but these relationships were attenuated after adjustment for cardiovascular risk factors. Lung function was not associated with coronary atherosclerosis in 14,524 never-smokers. No potentially causal effect of lung function on atherosclerosis, or vice versa, was found in the 2-sample Mendelian randomization analysis. Here we show that reduced lung function and atherosclerosis are correlated in the population, but probably not causally related. Assessing lung function in addition to conventional cardiovascular risk factors to gauge risk of subclinical atherosclerosis is probably not meaningful, but low lung function found by chance should alert for atherosclerosis.

Research review (peer-reviewed)abstract
- In discussions on intestinal protection, the protective capacity of mucus has not been very much considered. The progress in the last years in understanding the molecular nature of mucins, the main building blocks of mucus, has, however, changed this. The intestinal enterocytes have their apical surfaces covered by transmembrane mucins and the whole intestinal surface is further covered by mucus, built around the gel-forming mucin MUC2. The mucus of the small intestine has only one layer, whereas the large intestine has a two-layered mucus where the inner, attached layer has a protective function for the intestine, as it is impermeable to the luminal bacteria.

Facilitating green delivery options for consumers through interaction : A retailer perspective
- 2021
-
Conference paper (other academic/artistic)abstract
- Efficient goods distribution is key to the success of e-commerce and can even be a means for retailers to stay ahead of competition. However, e-commerce distribution also has a negative environmental impact. In fact, e-commerce distribution is often the most inefficient and the least environmentally sustainable part of the supply chain (Gevaers et al., 2014; Mangiaracina et al., 2015). Given the rate of e-commerce growth, measures need to be taken to reduce the environmental impact from e-commerce distribution. Retailers are under pressure to act sustainably and are even suggested to have a responsibility to support consumers in behaving more sustainably (Wiese et al., 2015). Consumers are also vital to the challenge of improving environmental sustainability of e-commerce distribution (Buldeo Rai et al., 2019). They are often given a number of delivery options to choose from, and their choices affect the environmental impact. For example, consumers that are willing to wait a few extra days for their ordered products create better conditions for logistics service providers (LSPs), on which many retailers rely to execute the distribution of sold goods, to increase fill-rates of their vehicles and thereby decrease the environmental impact. For consumers to be able to make more environmentally sound choices of distribution, they need guidance when choosing delivery options. Providing such guidance constitutes a large challenge for retailers, as the most environmentally sustainable choice is far from intuitive (e.g. van Loon et al., 2015). In fact, retailers are largely dependent on other actors to succeed. For example, LSPs have the expertise related to the environmental effects of their logistics operations. As a retailer, taking on the challenge of offering green delivery options is often more complex than it would seem at first hand, since LSPs and retailers need to coordinate their respective networks and efforts. This paper takes an interaction perspective of this challenge, as a means to expand the understanding of the actors that need to be involved for green delivery options as presented to consumers. The purpose of the paper is to increase the understanding of how retailers can facilitate green delivery options for consumers through interaction with other actors. A literature review of green logistics literature serves as a point of departure as to what can constitute a green delivery option for consumers. Empirically, the paper is based on a single case study of a Swedish retailer with both physical stores and an online sales channel. The case company was selected due to its high ambition and determination to be able to offer green delivery options to consumers. Data was gathered through meetings, semi-structured interviews and documents provided by the company. Early results suggest that retailers need to interact with a number of actors to be able to offer green delivery options for consumers. In order for the green delivery options to be trustworthy, the retailer needs to have an understanding of the environmental impact of their different distribution alternatives. To gain such knowledge, interaction with their contracted LSPs is necessary, as they have the knowledge of the environmental impact of their operations in different contexts. Interestingly, the studied retailer also had close interaction with a consulting firm, whose role was to secure the quality of the LSPs’ data and to compare the delivery options in terms of environmental impact. When a retailer has an overview of the environmental impact of different delivery options, this knowledge needs to be transferred into green delivery options that are understandable and accessible for consumers. As retailers often rely on other actors to provide platforms though which consumers make their choice of delivery, interaction with such companies can be vital. In the studied case, the interaction between the retailer and the platform developer, combined with extensive internal interaction on the retailer’s part, lead to a website presentation of the green delivery options for consumers. Finally, interaction with consumers is of importance for retailers to understand how consumers react to the green delivery options. The findings suggest that for retailers to be able to offer green delivery options for consumers, a larger number of actors need to be involved than what has been suggested in previous literature, in which retailers, LSPs and consumers are commonly mentioned. Furthermore, LSPs may have a surprisingly peripheral role in the development of the green aspect of the service offering compared to what earlier research has suggested. By studying green distribution in relation to consumer offerings, this paper helps bridge the gap between the two research fields green logistics and e-commerce. In terms of practical implications, this study can be used by retailers to better understand how they can proceed in order to offer green delivery options to consumers.

Book chapter (peer-reviewed)abstract
- E-commerce presents a fantastic opportunity for consumers to receive product deliveries anytime, anyhow and anywhere. However, a major challenge for all logistics systems is that of environmental sustainability, and for e-commerce, the distribution of products to consumers constitutes one of the largest environmental challenges. This chapter focusses on green distribution alternatives for consumers, and thereby provides an overview of how e-commerce can become more environmentally sustainable through offering such alternatives. The chapter starts by pointing to two major trends behind the greening of e-commerce: the growth of e-commerce itself and the increasing societal and corporate concern for environmental sustainability. Building on a series of studies of e-commerce development on the Swedish market, the perspectives of consumers, retailers and logistics service providers paint a broad picture of e-commerce delivery. Finally, today’s as well as potential future challenges for sustainable e-commerce deliveries are discussed.

Klimatsmart e-handelsdistribution : Hur svårt kan det vara?
- 2022
-
In: Supply chain effect. ; :4, s. 12-19
-
Journal article (pop. science, debate, etc.)abstract
- Logistik spelar en viktig roll för e-handelns miljöpåverkan och e-handelns framfart medför att konsumenten i allt större utsträckning kan, och vill, påverka den miljömässiga hållbarheten i logistiken. Särskilt i den senare delen av försörjningskedjan, det som ofta kallas sista milen, så har konsumenten stor makt att påverka.

Slutrapport: Hållbar distribution i e-handeln : Hur kan klimatsmarta leveransalternativ underlättas?
- 2023
-
Reports (other academic/artistic)abstract
- Inom ramen för det VINNOVA-finansierade projektet ”Hållbar distribution i e-handeln: Hur kan klimatsmarta leveransalternativ underlättas” (HELSMART) har syftet varit att ta fram kunskap om hur e-handlare kan utforma och presentera klimatsmarta leveransalternativ till konsumenter för att minimera klimatpåverkan från e-handelsdistributionen, och på så sätt bidra till ett fossilfritt samhälle. I denna rapport presenteras resultaten från projektet, som pågått under 2020-2023 och som varit ett samarbete mellan Linköpings Universitet och Stockholms Universitet. Projektet har kombinerat olika datainsamlingsmetoder, vilket gett möjlighet att förstå utmaningen med hållbara e-handelsleveranser ur olika perspektiv. Metoderna inkluderar dels en genomgång av e-handlares hemsidor, dels fallstudier och intervjuer med e-handlare, logistikföretag och transportplattformsföretag, och dels konsumentdata från faktiska köp före och efter introduktionen av ”miljömärkning” av leveranser. Sammantaget har det här projektet följt utvecklingen av miljömässigt hållbar e-handelsdistribution i en svensk kontext under de senaste nästan fyra åren. Resultaten visar att det finns en enorm komplexitet kopplat till miljömässigt hållbara leveransalternativ. För att belysa denna komplexitet så presenteras i rapporten en process som beskriver tre steg för att kunna utforma och presentera klimatsmarta leveransalternativ till konsumenter. Dessa innefattar: Identifiera miljömässigt hållbara leveransalternativ, Erbjuda miljömässigt hållbara leveransalternativ till konsumenter, och Vägleda konsumenters val av miljömässigt hållbara leveransalternativ. Genomgång av de tre stegen leder sedan fram till en avslutande diskussion där fyra centrala budskap lyfts. För det första är det inte självklart vad som menas med miljömässigt hållbar leverans. Här finns t.ex. oklarheter i vad man är ute efter att minimera när man vill uppnå miljömässigt hållbara leveranser, och om och hur det går att jämföra olika logistikföretags utsläpp på ett rättvisande sätt. För det andra så befinner sig e-handlarna inte i ett vakuum utan är beroende av andra aktörer, vilket gör att de slutgiltiga utsläppen beror på beslut från en mängd olika och starkt skilda beslutsfattare. För det tredje så skapar externa märkningar transparens, samtidigt som de riskerar att skapa förvirring. För samtidigt som externa märkningar har sina fördelar, så kan de också leda till att för många typer av miljömässigt hållbara leveransalternativ kommuniceras parallellt. För det fjärde så visar resultaten att hållbara leveransalternativ är viktiga för konsumenter, men inte lika viktigt som allt annat. Men genom att placera det miljömässigt hållbara leveransalternativet högst upp i checkouten och markera det som förvalt, så ökar sannolikheten för att konsumenter ska välja detta alternativ. Små knuffar på tillräckligt många kan på sikt ha enormt stor effekt på totala utsläpp.
