Abstract [en]

The objective was to examine 10-year changes in dietary carbon footprint relative to individual characteristics and food intake in the unique longitudinal Västerbotten Intervention Programme, Sweden. Here, 14 591 women and 13 347 men had been followed over time. Food intake was assessed via multiple two study visits 1996–2016, using a 64-item food frequency questionnaire. Greenhouse gas emissions (GHGE) related to food intake, expressed as kg carbon dioxide equivalents/1000 kcal and day, were estimated. Participants were classified into GHGE quintiles within sex and 10-year age group strata at both visits. Women and men changing from lowest to highest GHGE quintile exhibited highest body mass index within their quintiles at first visit, and the largest increase in intake of meat, minced meat, chicken, fish and butter and the largest decrease in intake of potatoes, rice and pasta. Women and men changing from highest to lowest GHGE quintile exhibited basically lowest rates of university degree and marriage and highest rates of smoking within their quintiles at first visit. Among these, both sexes reported the largest decrease in intake of meat, minced meat and milk, and the largest increase in intake of snacks and, for women, sweets. More research is needed on how to motivate dietary modifications to reduce climate impact and support public health. © 2020, The Author(s).

Abstract [en]

The average Swedish household throws away 480 kg of solid garbage per year. But this amount of material is only a small share of the resource consumption that our lifestylegives rise to. Our homes need to be built, goods produced, we are transported,and food is produced. In today's linear consumption society, every individual inthe EU is estimated to have a material footprint of 29 tons/year on average – afootprint that needs to shrink to 8 tons in order to stay within “planetaryboundaries”. In a circular system, products are recycled and shared leading toless resources and materials needed, but do we know how much? Which resourceand material consumption is generated in Sweden? What could we achieve througha transition to a sharing and circular economy, and how would our consumptionpatterns look like within a sustainable material lifestyle? The goal of thisstudyis to assess the material footprint of sharing and circular lifestyles inhousing, mobility and food system. "8 ton society" takes athree-level method approach: (1) National: assessing the material footprint ofsharing and circular lifestyles in housing, mobility and food systems on anational level. (2) Municipal: Mapping material and waste streams at municipallevel (for the three Swedish municipalities Göteborg, Malmö och Umeå), by whichmunicipalities can identify opportunities for a circular society, for exampleby supplementing existing climate strategies and waste plans with circularaction plans. (3) Household: Combined with a household level analysis ofmaterial footprints, the project contributes to behavioral change at householdlevel as well as strengthened decision making and innovation at national andmunicipal level. The results of the study are material footprints and scenariosthat are used as basis for the development of reduction measures. The scenariosdescribe potential “8t societies” for Sweden, meaning potential policy andsocietal innovations that allow for a drastic reduction of material footprint.These include sharing and circular solutions. Additionally, the project willcontrast the Swedish results to similar projects that have been carried out in Finland and Germany.

Abstract [en]

Objective:The objective of this study was to examine climate impact from diet across background and sociodemographic characteristics in a population-based cohort in northern Sweden.Design:A cross-sectional study within the Västerbotten Intervention Programme. Dietary data from a 64-item food frequency questionnaire collected during 1996-2016 were used. Energy-adjusted greenhouse gas emissions (GHGE) for all participants, expressed as kg carbon dioxide equivalents/day and 4184 kJ (1000 kcal), were estimated using data from life cycle analyses. Differences in background and sociodemographic characteristics were examined between participants with low and high GHGE from diet, respectively. The variables evaluated were age, BMI, physical activity, marital status, level of education, smoking, and residence.Setting:Västerbotten county in northern Sweden.Participants:In total, 46 893 women and 45 766 men aged 29-65 years.Results:Differences in GHGE from diet were found across the majority of examined variables. The strongest associations were found between GHGE from diet and age, BMI, education, and residence (all P < 0·001), with the highest GHGE from diet found among women and men who were younger, had a higher BMI, higher educational level, and lived in urban areas.Conclusions:This study is one of the first to examine climate impact from diet across background and sociodemographic characteristics. The results show that climate impact from diet is associated with age, BMI, residence and educational level amongst men and women in Västerbotten, Sweden. These results define potential target populations where public health interventions addressing a move towards more climate-friendly food choices and reduced climate impact from diet could be most effective.

Abstract [en]

Although food production is a main driver of environmental pressure and resource use globally, food delivers critical nutrition to humans. In life cycle assessment (LCA) of foods, the dominant functional unit is mass, despite the ISO requirement that the LCA unit should reflect the actual function. Studies have used various dietary quality scores in environmental assessments of foods, but the consideration of the dietary context is largely missing. The main function, i.e., nutrient supply, is complex since the nutritional value of a food item depends on its dietary context. Moreover, overall nutritional value is a combination of multiple nutrients. The aim was to combine scientific knowledge from the fields of nutrition and LCA to generate a basis for further research. The long-term aim was to help develop methods to support sustainability-based planning and decision making by food chain stakeholders. The proposed functional unit expresses the nutrient content of individual foods in relation to the nutritional supply of the complete diet, to create a single score reflecting the nutrient quality in a given dietary context. The nutrient quality index developed was evaluated by analyzing how relationships in global warming potential (GWP) between single products differed when using as functional unit either the mass of the food product, a nutrient quality index not considering the dietary context (the Nutrient Rich Foods Index 9.3, NRF9.3) and the new dietary dependent nutrient quality index (NQI) proposed. Two dietary scenarios were explored, an average Swedish diet and a typical unhealthy diet. The products considered were: bread, apples, tomatoes, milk, hard cheese, spread and chicken fillets. The results, calculated using bread as the reference, indicated that in both dietary contexts apples, tomatoes, and hard cheese had lower NQIadjusted GWPs compared to when GWPs were calculated using mass as the functional unit. Milk's NQI-adjusted and mass-calculated GWPs differed little, while the chicken fillet GWPs were the same in the unhealthy diet and performed better in the average diet. The NRF9.3-adjusted GWPs differed from the NQI-adjusted ones for all analysed foods. The main conclusions were: 1) considering nutritional value in the LCA of foods improves our understanding of how the environmental impacts and nutritional functions of food are related; 2) the environmental performance of different products varies with dietary context; and 3) application of the NQI could help industry, authorities, and consumers improve products and diets.

Abstract [en]

There is great potential for reducing greenhouse gas emissions (GHGE) from public-sector meals. This paper aimed to develop a strategy for reducing GHGE in the Swedish school food supply while ensuring nutritional adequacy, affordability, and cultural acceptability. Amounts, prices and GHGE-values for all foods and drinks supplied to three schools over one year were gathered. The amounts were optimized by linear programming. Four nutritionally adequate models were developed: Model 1 minimized GHGE while constraining the relative deviation (RD) from the observed food supply, Model 2 minimized total RD while imposing stepwise GHGE reductions, Model 3 additionally constrained RD for individual foods to an upper and lower limit, and Model 4 further controlled how pair-wise ratios of 15 food groups could deviate. Models 1 and 2 reduced GHGE by up to 95% but omitted entire food categories or increased the supply of some individual foods by more than 800% and were deemed unfeasible. Model 3 reduced GHGE by up to 60%, excluded no foods, avoided high RDs of individual foods, but resulted in large changes in food-group ratios. Model 4 limited the changes in food-group ratios but resulted in a higher number of foods deviating from the observed supply and limited the potential of reducing GHGE in one school to 20%. Cost was reduced in almost all solutions. An omnivorous, nutritionally adequate, and affordable school food supply with considerably lower GHGE is achievable with moderate changes to the observed food supply; i.e., with Models 3 and 4. Trade-offs will always have to be made between achieving GHGE reductions and preserving similarity to the current supply.

Abstract [sv]

Syftet med rapporten är att skapa ett underlag för mer operativa, eller konkreta, hållbarhetsmål för aktörerna i livsmedelskedjan. Dessa mål ska i möjligaste mån vara kopplade till kvantifieringar av en hållbar nivå för resursförbrukning och miljöpåverkan globalt.

Rapporten beskriver en process som startar med att identifiera de relevanta hållbarhetsaspekterna för livsmedelsystemet och baserat på litteratur kvantifiera dessa på global nivå, nedbrutet till en globalt hållbar nivå per capita. Som ett komplement till det globala användes också nationella källor för de miljömål som är av mer regional karaktär. Livsmedelssektorns hållbarhetsprestanda är en kombination av konsumtionsmönster och hur effektiva och hållbara produktionssystemen är. Då rapporten syftade till att ge underlag för konkreta mål för alla aktörer i systemet skapades två typer av mål, en typ som berör konsumtionsmönster och en typ som berör produktionskedjornas hållbarhetsprestanda. För att de totala hållbarhetsmålen ska nås måste både konsumtionen och produktionen förändras, och med hjälp av dessa två mål kan båda aspekterna hanteras i samma ramverk. Om produktionssystemen inte förbättrar sin hållbarhetsprestanda krävs större förändringar i konsumtionen och vice versa.

De mål som sätts för försäljning/tillhandahållning till konsument i rapporten är avsedda att användas av aktörer som säljer eller på annat sätt har möjlighet att påverka konsumtionsmönster, som exempelvis handel, food service och den offentliga måltidssektorn. Dessa mål ger en bild av faktisk slutkonsumtion. De mål som sätts för produktionen, alltså produktionens värdekedjor, är avsedda att användas av aktörer som producerar livsmedel, alltså lantbruk och livsmedelsindustri.

Det var inte möjligt att sätta kvantitativa mål för alla relevanta hållbarhetsaspekter, för vissa aspekter finns inga vetenskapliga uppskattningar av den hållbara nivån för påverkan. Brist på metodik och data är ett annat allvarligt hinder för att sätta operativa mål. I rapporten har dessa kunskapsluckor identifierats och alternativa mål har föreslagits för att alla aspekter ska kunna hanteras konkret. Med alternativa mål menas mål som kan bygga på indirekta mått på hållbarhet som exempelvis energibesparingsmål istället för ett mål om hur stor den totala energianvändningen kan vara, då detta inte finns kvantifierat.

Abstract [en]

Agricultural waste is a huge pool of untapped biomass resources that may even represent economic and environmental burdens. They can be converted into bioenergy and bio-based products by cascading conversion processes, within circular economy, and should be considered residual resources. Major challenges are discussed from a transdisciplinary perspective, focused on Europe situation. Environmental and economic consequences of agricultural residue management chains are difficult to assess due to their complexity, seasonality and regionality. Designing multi-criteria decision support tools, applicable at an early-stage of research, is discussed. Improvement of Anaerobic Digestion (AD), one of the most mature conversion technologies, is discussed from a technological point of view and waste feedstock geographical and seasonal variations. Using agricultural residual resources for producing high-value chemicals is a considerable challenge analysed here, taking into account innovative eco-efficient and cost-effective cascading conversion processes (bio-refinery concept). Moreover, the promotion of agricultural residues-based business is discussed through industrial ecology, to promote synergy, on a local basis, between different agricultural and industrial value chains. Finally, to facilitate a holistic approach and optimise materials and knowledge flows management, the connection of stakeholders is discussed to promote cross-sectorial collaboration and resource exchange at appropriate geographic scales. © 2018, © 2018 Nathalie Gontard, Ulf Sonesson, Morten Birkved, Mauro Majone, David Bolzonella, Annamaria Celli, Hélène Angellier-Coussy, Guang-Way Jang, Anne Verniquet, Jan Broeze, Burkhard Schaer, Ana Paula Batista, and András Sebok.

Abstract [en]

Knowledge about the environmental impact of alcohol is limited and as an effect alcohol is often excluded from environmental studies of diets or included in incomplete ways. This paper describes the climate impact of beer, wine and liquor by using life cycle assessment. The climate impact is quantified per litre of specific alcoholic beverages and per total amount of alcohol consumed based on self-reported data of 50 000 individuals from 2009 within two population-based cohorts in Sweden. The results show that alcoholic beverages generate greenhouse gas (GHG) emissions in the range of 0.73–2.38 kg carbon dioxide equivalents (CO2e) per litre. Alcohol consumption in the population studied generates on average 52 kg CO2e per person and year. Within the 10% of the population with the highest intake of alcohol GHG emissions are up to 202 kg CO2e per person and year. Consumption of wine is responsible for the largest share of GHG emissions from alcoholic beverages (61%) followed by beer (33%), while liquor and strong wine account for a smaller share (6%). Alcohol consumption among men generates 90% higher GHG emissions than among women. Alcohol consumption and in consequence alcohol-related emissions are decreasing with increasing age of men and women. Our results indicate that alcohol consumption in Swedish men and women is responsible for an average of 3% of total diet-related GHG emissions and in sub-populations with the highest consumption up to 6–11%. Limiting alcohol could be an effective option to reduce the climate impact of diets, especially among men.

Abstract [en]

The increased recognition of inter-relationships between the environmental and health effects of food has resulted in a new fast-growing research area. Development of methods for integrated analysis of environmental and nutritional impacts is essential to facilitate policy decisions and actions for sustainable food systems. Dietary quality scores is one of the methods suggested to combine environmental and nutritional assessments of foods, meals and diets. This systematic review provides an overview of how dietary quality scores are used in environmental sustainability studies of food products and diets. The review includes 24 articles applying 20 different types of dietary quality scores. We describe current approaches used to combine environmental and nutritional assessments, discuss methodological choices of importance and their impact on results, and identify research gaps that require further efforts to push the current frontier of knowledge. Based on our analysis we identify two different categories of dietary quality scores and four approaches used to integrate environmental and nutritional assessments. There is a large number of methods available to quantify a dietary quality score: which one is chosen as well as how they are combined with environmental assessments can affect the results, and hence also the conclusions of which foods that are more sustainable to eat. This is critical to understand for the set-up of studies and for the interpretation of results and drawing conclusions. Our categorization of existing methods used, how they differ, what applications they are suited for, and which methodological challenges they involve increases the understanding of what analyzes are possible today and point out areas where methods are lacking and where more research is required. Continued efforts are needed to bring about a transition to sustainable food systems that do not exceed the planets ecological limits and promote healthy populations. This systematic review provides guidance for future use and development of methods within the field of sustainable nutrition.

Abstract [en]

To achieve a more sustainable food sector, a supply chain approach is needed. In this study, experts in different areas along supply chains co-operated in an interactive process to define future environmentally sustainable supply chains of milk and beef. The basis was to use existing techniques, to have production performance corresponding to the best quartile of today and to consider other sustainability aspects, such as economics. The work resulted in concrete descriptions of alternative product chains for delivered milk and beef. To also permit concrete descriptions of the latter part of the product chains, two consumer-packed end products were selected for monitoring, namely fresh milk and sirloin steak. The production systems investigated comprised cropping, livestock production, industrial processing and production, logistics, packaging and wastage and distribution, but not retailers or consumers. The study area was a Swedish county and the reference level was its production of milk and beef in 2012. The future product chains were assumed to deliver the same amounts of commodities as in 2012, but with reduced environmental impact. Primary production was required to be at least as profitable as today. Beside description of the current situation, three alternative scenarios were created, focusing on delivery of ecosystem services, plant nutrient circulation and minimising climate impact, respectively. Life cycle assessments were performed for these four scenarios (reference plus three alternative scenarios) for single-product chains and county-wide. Furthermore, production costs in primary production were calculated for the four scenarios. The results revealed great potential to reduce the negative environmental impact of Swedish dairy and beef production at current volumes, irrespective of whether ecosystem services, plant nutrient circulation or climate impact is in focus. The single most important factor for decreased environmental impact for livestock production was increased production efficiency. Measures in agriculture, especially concerning feeds, were critical, but actions in processing and distribution also contributed. All alternative scenarios resulted in lower production costs than at present. It was obvious that as dairy and beef systems are connected, the potential for their environmental improvement must be analysed together. In conclusion, increased efficiency can decrease the negative environmental impact of Swedish cattle production and also reduce costs to the farmer.
