Abstract [en]

Food waste prevention has become an issue of international concern, with Sustainable Development Goal 12.3 aiming to halve per capita global food waste at the retail and consumer levels by 2030. However there is no review that has considered the effectiveness of interventions aimed at preventing food waste in the consumption stages of the food system. This significant gap, if filled, could help support those working to reduce food waste in the developed world, providing knowledge of what interventions are specifically effective at preventing food waste.

This paper fills this gap, identifying and summarizing food-waste prevention interventions at the consumption/consumer stage of the supply chain via a rapid review of global academic literature from 2006 to 2017.

We identify 17 applied interventions that claim to have achieved food waste reductions. Of these, 13 quantified food waste reductions. Interventions that changed the size or type of plates were shown to be effective (up to 57% food waste reduction) in hospitality environments. Changing nutritional guidelines in schools were reported to reduce vegetable waste by up to 28%, indicating that healthy diets can be part of food waste reduction strategies. Information campaigns were also shown to be effective with up to 28% food waste reduction in a small sample size intervention.

Cooking classes, fridge cameras, food sharing apps, advertising and information sharing were all reported as being effective but with little or no robust evidence provided. This is worrying as all these methods are now being proposed as approaches to reduce food waste and, except for a few studies, there is no reproducible quantified evidence to assure credibility or success. To strengthen current results, a greater number of longitudinal and larger sample size intervention studies are required. To inform future intervention studies, this paper proposes a standardised guideline, which consists of: (1) intervention design; (2) monitoring and measurement; (3) moderation and mediation; (4) reporting; (5) systemic effects.

Given the importance of food-waste reduction, the findings of this review highlight a significant evidence gap, meaning that it is difficult to make evidence-based decisions to prevent or reduce consumption-stage food waste in a cost-effective manner.

Abstract [en]

A warmer climate leads to rising sea levels. Despite uncertainties about how rapid and substantial future sea-level rise (SLR) will be, society needs to prepare and adapt. This study examines the state of planning for future SLR in Sweden by surveying 33 coastal municipalities in southern Sweden and interviewing local, regional and national authorities with relevant accountability. The results reveal that there are considerable gaps in current planning for SLR. Almost one-third of municipalities lack guiding planning documents for SLR, and more than two-thirds do not discuss SLR beyond 2100. We argue that the prevailing uncertainty and ambiguity in assessments of future SLR is problematic within a traditional “predict-then-act” paradigm, and that robust approaches, such as scenario planning, can reduce many of these problems.

Abstract [sv]

Den starka forskningsmiljön “Bortom BNP-tillväxt - Scenarier för hållbart samhällsbyggande” undersöker vad som skulle kunna hända i det svenska samhället när tillväxt inte ses som ett självändamål, utan målet istället är kvaliteter samhället kan tänkas vilja uppnå. Syftet med denna rapport är att beskriva testversionen av scenarier för Sverige 2050. Scenarierna är kvalitativa och ska skapa underlag för fortsatt utveckling, diskussioner och analys. Scenarierna är så kallade normativa backcasting-scenarier vilket innebär att de visar på framtida tillstånd där fyra hållbarhetsmål (klimat, markanvändning, delaktighet och försörjningstrygghet) ska uppfyllas. Inriktningen på de fyra scenarier är 1) kollaborativ ekonomi, 2) lokal självförsörjning, 3) automatisering för livskvalitet, och 4) cirkulär ekonomi i välfärdsstaten. Scenarierna presenteras som beskrivningar av framtiden i Sverige och med en kort beskrivning av den globala utvecklingen och utvecklingen i Sverige som kan förklara scenariots antaganden. Mycket arbete återstår. Till exempel ska scenarierna presenteras och diskuteras i flera forum det kommande året och återkoppling från diskussionerna ska arbetas in i en ny version av scenarierna. Ekonomiska modelleringar av scenarierna kommer också att genomföras, och därefter hållbarhetsutvärderingar och fördjupningar av delar av scenarierna

Abstract [en]

The strong research environment ”Beyond GDP growth - Scenarios for sustainable building and planning” explores what could happen in the Swedish society when growth is not seen as an end in itself but the goal is instead other qualities that society might wish to achieve. The purpose of this report is to describe the test version of scenarios for Sweden in 2050. The scenarios are qualitative and aim to create a basis for further development, discussion and analysis. The scenarios are so-called normative backcasting scenarios which means that they illustrate future states in which four sustainability targets (climate, land use, participation and resource security) are to be attained. The focus of the four scenarios are: 1) collaborative economy, 2) local self-sufficiency, 3) automisation for quality of life, and 4) circular economy in the welfare state. The scenarios are presented as descriptions of the future in Sweden, with a brief description of global trends and developments in Sweden that may explain the scenario assumptions. A lot of work remains. For example, the scenarios will be presented and discussed in several forums in the coming year, and the feedback from the discussions will be incorporated into a new version of the scenarios. Economic modeling of the scenarios will also be performed, and after that sustainability assessments of scenarios and in depth studies of parts of the scenarios.

Abstract [en]

Transition from the current oil-based world economy to an economy based on renewable resources can become a strong driving force for land use change. This paper describes the development of integrated explorative and normative scenarios for the analysis of future land use in a climate-neutral Sweden. The aim is to show how backcasting scenarios fulfilling far-reaching greenhouse gas reduction targets can be related to assumptions on possible external developments, in order to contribute to the discussion on future sustainable land use. A target-fulfilling scenario element was combined with an external scenario element, i.e. developments that cannot be influenced by the targeted actors. The scenarios were developed and analysed in collaboration with local actors. Four scenarios were used to describe how land in Sweden could be used when Sweden has achieved zero emissions of greenhouse gases in 2060. The explorative dimension stretched from a situation where there is no international climate agreement to one where there is an international agreement on reducing greenhouse gases. The backcasting dimension illustrated different strategies to achieve the target and stretches from a very influential municipal level to one where the national/EU level is most influential.

Abstract [en]

Information and Communication Technology (ICT) can have both negative and positive impacts on the environment. Immediate negative environmental impacts arise due to the production, use and disposal of ICT products, while positive effects can arise because ICT products and services replace other products. Other, more indirect consequences of introducing new technologies include e.g. that money saved by reducing costs due to ICT-induced energy efficiency, is being used in consumption of other goods and services that also need energy in their production. Such effects are examined within different disciplines under headings such as rebound effects, indirect effects, second order effects and ripple effects. This paper presents a review and discussion of different second order effects that can be linked to ICT usage in general, using e-commerce as an example. This is a first necessary step in developing methods which include second order effects when analysing the environmental impacts of ICT.

Abstract [en]

Forest biomass is used for many products including paper based products, sawn wood products and solid fuels. The production of forest derived liquid transportation fuels is currently limited  but predicted to increase.

Biomass is a renewable resource and therefore of high interest for applications such as new innovative materials, liquid and gaseous fuels. The production of various biofuels for transportation is forecast to increase and Sweden has a goal of a fossil-independent transportation system by 2030. Other, non-material, uses of forest biomass include the so called eco system services biodiversity, fishing, hunting, recreation, berry picking etc. which are also competing for forest biomass.

There is currently a net growth of forest in Sweden, which theoretically could allow for an increased use of this resource. However, the amount of forest biomass is not unlimited and its harvest should not exceed its growth. Therefore, forest biomass should be considered as a limited resource and its use should aim to maximize the environmental benefit compared to the use of fossil resources. For this reason, environmental impact evaluations of forest biomass based products should include alternative sources for products competing with this resource.

The pre-study reported herein included: a review of Swedish forestry and the relationships between different types of forest biomass and fuels; a workshop in which the competition for forest biomass was discussed with experts in the area; a theoretical reasoning around indirect effects and biomass potentials; and two case studies in which the theoretical reasoning is applied. Traditional assessments of environmental impacts of products and processes do not include the aspect of resource scarcity or competition for raw materials. In the case of bioethanol this has been shown to affect the results of such evaluation andthe same thing applies also to other forest biomass based fuels.

The main conclusion of the study is that alternative sources for products competing with forest biomass should be taken into account when assessing the environmental impacts of forest biomass derived products. This is, however, complex as indirect effects are difficult to predict and depend on numerous factors including market situations, financial instruments, legislation and policies etc. Nevertheless, the question is important for the development of biobased substitutes for fossil derived products .

Abstract [en]

The aim of this paper is to suggest and discuss policy instruments that could lead towards a more sustainable waste management. The paper is based on evaluations from a large scale multi-disciplinary Swedish research program. The evaluations focus on environmental and economic impacts as well as social acceptance. The focus is on the Swedish waste management system but the results should be relevant also for other countries. Through the assessments and lessons learned during the research program we conclude that several policy instruments can be effective and possible to implement. Particularly, we put forward the following policy instruments: “Information”; “Compulsory recycling of recyclable materials”; “Weight-based waste fee in combination with information and developed recycling systems”; “Mandatory labeling of products containing hazardous chemicals”, “Advertisements on request only and other waste minimization measures”; and “Differentiated VAT and subsidies for some services”. Compulsory recycling of recyclable materials is the policy instrument that has the largest potential for decreasing the environmental impacts with the configurations studied here. The effects of the other policy instruments studied may be more limited and they typically need to be implemented in combination in order to have more significant impacts. Furthermore, policy makers need to take into account market and international aspects when implementing new instruments. In the more long term perspective, the above set of policy instruments may also need to be complemented with more transformational policy instruments that can significantly decrease the generation of waste.
