Contested representations: A comparative analysis of palm oil sustainability in Malaysian and Dutch media

The emergence of palm oil as the world's most produced and consumed vegetable oil has prompted various policy initiatives to help govern the industry in a sustainable manner. These initiatives include transnational sustainable certification schemes, such as the Roundtable of Sustainable Palm Oil (RSPO), and national level sustainability standards, such as Malaysian Sustainable Palm Oil. To date, attempts to find consensus on sustainable policy and processes has been characterised by tension and disagreement. Most notably, stakeholders participating in policy dialogue from producing countries are unsatisfied with the outcomes of transnational palm oil governance. Tension stems from observations that sustainability is understood differently in the palm oil producing countries of the Global South compared with Northern consumption markets. To understand the different framings of palm oil and potential governance solutions, we investigate media coverage of palm oil sustainability in two different countries: the Netherlands – the largest importer of palm oil in Europe – and Malaysia – the second largest exporter of palm oil in the world after Indonesia. From a sample of 397 Malaysian and Dutch newspaper articles between 2000 and 2015, we employ framing analysis to examine the similarities and differences in media representations of palm oil sustainability. Our findings reveal considerable differences in the way palm oil sustainability is framed in the two countries. Malaysian media frame palm oil as a sustainable industry yet underpinned by a distrust towards transnational sustainability governance (e.g. RSPO) and a perception of unfair treatment towards producing countries by the West. Conversely, Dutch media frame the West as proud consumers of palm oil, who are driving up sustainability standards through NGO scrutiny and participation in transnational processes. We argue that a comparative analysis of media frames offers instructive insights for understanding processes of transnational sustainability governance. In particular, we posit that reconciling policy tensions between North and South palm oil stakeholders could be achieved by highlighting the differences in sustainability framings at different points in the value chain to identify contestation and consensus.

Collaborating with a Scottish Heritage Brand towards Enhancing and Preserving Sustainable Artisan Hand-Weaving Practices through a Knowledge Transfer Partnership

This paper discusses a Knowledge Transfer Project (KTP) with a global Scottish heritage brand to develop a year-round sustainable business model through a design-led approach to new product innovation that improves their sustainability credentials. Sustainability in textile production is under increasing scrutiny from the media, governments, regulators, and consumers, all demanding transparency in the supply chain. The company has an excellent track record of sustainable employment in rural communities and sought through the project to improve their production processes and waste output. Sustainability is a vast topic, where collaboration can help to address these key challenges. The company manages an artisan hand-weaving manufacturing system where yarn production and fabric finishing are regulated by the 1993 Harris Tweed Act of Parliament that protects and restricts production to the Outer Hebrides. The success or failure of the Harris Tweed® industry directly impacts the wider economy of the Outer Hebrides, which is considered “remote, rural, fragile” by UK and Scottish governments and their economic development agencies. The paper describes how academic/business collaboration can positively encourage innovation and help reposition businesses within a changing economic and sustainable landscape that explores these new opportunities. The paper reflects on how KTPs are a mechanism with mutual benefits, where pooling individual knowledge and resources can develop strong, sustainable, and authentic relationships that can provide tangible impacts of new knowledge generation and application within a scholarly and research context that can be clearly aligned to notions of bringing value to the sector, users, and the curriculum.

Viewpoint: Should we care where our timber comes from?

Forester Jez Ralph looks at the types of timber available in the UK and encourages engineers to dig a little deeper to better understand the options for a project and their sustainability credentials.

Life cycle assessment comparison of point-of-use water treatment technologies: Solar water disinfection (SODIS), boiling water, and chlorination

Numerous different point-of-use (POU) water treatment technologies exist that can remove, reduce or inactivate microbial pathogens present in untreated drinking water. However, there have been uncertainties as to which technology is best suited to rural populations. Environmental impacts of these technologies can bring further threats to rural communities, so the life cycle assessment (LCA) approach is frequently used to compare different POU water treatment technologies. The present study uses LCA to compare three treatment options: solar water disinfection (SODIS) using a Transparent Jerrycan (TJC), boiling, and chlorination. A life cycle inventory database is created for each stage, calculating the embodied energy and transportation energy considering daily reliance for all the technologies. Direct carbon dioxide emission at the point of use of energy/fuel, particulate matter formation and smog formation analysis can help to implement the most appropriate technology. The life-cycle assessment in this study indicates that when considering the environmental impact associated with providing sufficient safe drinking water for a family of six over a period of 6 months, SODIS has been found to have better sustainability credentials as a water treatment technology (6.0 kg CO2e per functional unit) with low contribution in all the three impact categories, followed by chlorination (9.8 kg CO2 e per functional unit) and boiling water (6808 kg CO2e per functional unit).

Online sustainability claims: lessons from high-scoring B corporations in the Canadian food and beverage sector

PurposeSustainability certifications can support green innovation in important consumer sectors such as food and beverage. This research interrogates how certified companies communicate sustainability claims online and whether these practices differ from non-certified counterparts. The purpose of the study is to understand if certification stands to alter online communication about sustainability.Design/methodology/approachA discourse analysis of the websites and social media accounts of three highly-rated Canadian B Corps and three matching non-certified companies inductively identified 5 types of sustainability claims: transparency, brand story, green materials/processes, community engagement and sourcing partnerships. A comparative analysis was used to determine if certification alters corporate sustainability communication practices of firms.FindingsThe findings indicate that sustainability certifications alter external online sustainability communication. Of the 457 sustainability claims coded in the sample, 67.6% are from certified firms. Attaining certification also alters the areas of communication focus, increasing communication about the socially oriented community engagement dimension, which is often underrepresented.Originality/valueThe research contributes to the understanding of sustainability communication among privately held small and medium-sized enterprises (SMEs), which are currently underrepresented in the literature. The unique sampling used in this study considers how communication is altered post-certification as a novel way to understand the impacts of sustainability certifications.

Waste coal cement concrete for sustainable production

Concrete industry aims to mitigate its environmental footprint and provide cost-effective approaches for the promotion of sustainable development goals. Waste utilisation in concrete production could satisfy sustainability credentials. However, performance of waste incorporated mixes is not fully clear which limits the use of waste materials. Thus, a clear quantitative evaluation cannot be established. Locally obtained waste coal ash (WCA) was used in this study as a replacement to both CEM I and CEM II/B-S cements with replacement levels of 10 and 20% to achieve sustainable concrete production. Developed concretes were tested against various engineering properties (slump, density, compressive strength, water permeability and porosity) and sustainability characteristics (social, environmental and economic). A balanced scoring system have been used to evaluate the overall performance of laboratory mixes. Results revealed that WCA use provided similar slump values but reduced the fresh density. WCA mixes had lower compressive strength but enhanced absorption characteristics. Environmental and economic sustainability showed significant reductions while social sustainability indicators (sound permeability and thermal conductivity) showed enhanced performances for WCA mixes suggesting potential use for sustainable construction applications. Overall performances suggest that WCA mixes can improve overall performance by 11 and 15.5% for 10 and 20% replacement levels respectively.

Pre-certification conditions of independent oil palm smallholders in Indonesia. Assessing prospects for RSPO certification

Smallholders, who cultivate ±30% of the global palm oil land, are critical to the realization of a sustainable palm oil sector. However, particularly independent smallholders, untied to mills, lag behind in yields and experience challenges to market their produce. Sustainability certification, such as by the Roundtable on Sustainable Palm Oil (RSPO), is proposed as a way to improve smallholder livelihoods, while protecting the environment. However, independent smallholders experience barriers to obtain certification. Through interviews with 18 RSPO certified independent smallholder groups in Indonesia and 9 certification facilitators, this study examines how pre-certification conditions regarding smallholders’ socio-economic backgrounds, legality, group organization, planation management practices, and local supply chain conditions impact prospects for RSPO certification, and how groups who successfully achieved certification have dealt with challenges during the certification process. We found that the majority (77%) of RSPO certified independent smallholders in Indonesia consists of ‘former scheme’ smallholders. These smallholders often have clear land legality and are organized in groups prior to certification, which increases their eligibility for RSPO certification. However, due to upfront and recurrent costs for certification, as well as complexities in meeting RSPO standards, access to certification is strongly dependent on external facilitators. To up-scale certification for independent oil palm smallholders, and include more non-scheme smallholders, certification projects should involve more local actors including local governments and certified smallholder groups. In addition, certification should focus on core social and environmental concerns for smallholders, while being flexible with regards to the forms of proof needed to fulfil legality requirements.

Sustainability dichotomies of used clothes supply chains: a critical review of key concerns and strategic resources

PurposeUsed clothes supply chains are becoming increasingly complex, fragmented and less transparent due to rising volumes of discarded clothes and its dispersed reverse logistics operations across the Global North (GN) and Global South (GS). While it has a promising impact on circular economy and international trade growth, increasing exports of used clothes and overflowing landfills raise some negative concerns on its overall sustainability. This paper addresses the dichotomy that exists in terms of interpreting the sustainability credentials of used clothes supply chains.Design/methodology/approachA systematic literature review was carried out and 55 articles were examined to identify the triple bottom line (TBL) sustainability impacts of used clothes supply chains. TBL sustainability issues were identified, reflected through the lens of natural resource-based view and interpreted in the form of propositions.FindingsThe paper pinpoints seven TBL sustainability concerns and prescribes three sets of strategic resources required in glocal used clothes supply chains for mitigating these. These are (1) slowing the supply chain by tackling poor quality, overproduction and oversupply issues, (2) improving logistics/supply chain infrastructure and ecosystem collaboration and (2) embedding transparent environmental, social and governance (ESG) measures taken by both value chain actors and regulatory bodies, for embracing system-level sustainable development.Originality/valueThis is one of the first studies to analyse TBL sustainability of glocal north–south used clothes supply chains. The study is unique in terms of its scope and contribution to the sustainable supply chain literature.

Competency-Based Medical Education (CBME): an Overview and Relevance to the Education of Future Surgical Oncologists.

In the next two decades, the global cancer burden is expected to rise by 47%, and the demand for global cancer surgery will increase by 52%. At present, only 25% of the estimated 80% of patients needing surgical intervention have access to timely surgical care. The shortage of a trained workforce of surgical oncologists is one of the main barriers to providing the optimal surgical intervention needed for cancer patients. Some of the contributing factors to the shortage of trained surgical oncologists are variations in the current global educational platforms, long training programs, and physician burnout. Therefore, the availability of a credible training framework and a sustainable certification pipeline for future surgical oncologists is critical to meet the global demand for an adequate healthcare workforce. The current surgical oncology educational program is a time-based construct that trains surgeons to function seamlessly in the multidisciplinary care of cancer patients. However, there is a lack of flexibility in the training framework and timeline despite differences in trainees' abilities. Developing a globally acceptable standard curriculum for surgical oncology training based on the competency-based medical education (CBME) framework and tailoring it to local needs can increase the surgical oncology workforce ready to tackle the rising cancer burden. However, successful implementation of the global CBME-based surgical oncology training curriculum requires an innovative approach to ensure that this framework produces a competent surgical oncologist that meets the local needs.

Data fusion approach for a digital construction logistics twin

Construction site logistics deals with the transport and storage of materials as part of the execution of a construction project. An important part of construction logistics is informing those who are involved in the project about the current status of the ordered materials. On the one hand, the missing overview of the material inventory on the construction site and incoming deliveries makes efficient daily work planning on the construction site more difficult. On the other hand, unnecessary search and travel times reduce the productive working hours of employees on the construction site. In order to provide a better overview, the information from existing data sources must be linked and visualized in an easily understandable way for all project participants. Therefore, a digital construction logistics twin is proposed in this paper. Here, the challenge lies in the creation of the digital twin. The aim of this paper is to reduce the manual entry and planning effort needed. Therefore, an approach is proposed, which uses the Building Information Model (BIM), information from the technical specifications and bill of quantities as well as catalogue data from the building materials trade. The Building Information Model comprises the three-dimensional building model, information about the building components, the construction schedule (4D BIM) and the planned storage spaces on the constructions site. The catalogue data adds relevant logistic attributes and could also enables guidelines to be checked, e.g., as part of a sustainability certification (e.g., LEED). If the suppliers’ telemetry data were integrated, end-to-end material tracking would even be possible, similar to “track-and-trace” services from parcel service providers for end customers. The provision of all this data via a Building Information Model server as a “single source of truth” increases the transparency of the construction and logistics processes for everyone involved in the project. Also, this information would, for example, favor the use of autonomous means of transport, which reduces the need for manpower for transport on the construction site.

New CAP and the challenge of sustainability: a synthetic indicator for the Italian wine sector

Among the keys that enable the actors in the food chain in becoming more sustainable, the Strategy assigns an important role to knowledge and information. For this reason, the Farm to Fork Strategy aims to make the Farm Accountancy Data Network (FADN), the main data source of sustainable indicators, turning it into a Farm Sustainability Data Network (FSDN).
 Wine not only represents one of the most important products of the Italian agri-food system (value of turnover and exports), but it is also characterised by a widespread use of traditional certification systems (PDO/PGI, Organic), to which in recent years specific certifications of sustainability have been added, evaluated through its threefold dimension: economic, environmental, and social. Indeed, the wine sector is much ahead of others in the process of sustainability certification both for the process and the product itself.
 The paper is an effort to test the current set of information included in the FADN and some related computable indicators as a feasible tool for the assessment of sustainability in the wine sector. The goal of this paper is twofold. Firstly, we assess the actual level of sustainability of the wine sector in Italy through an indicator that synthetizes the three dimensions (economic, environmental, and social) of sustainability at the regional level. Secondly, more in general, we test the current capacity of the FADN information to provide a reliable measure of sustainability given the intention of the EU legislator to switch the European data network from FADN to FSDN.

Implications for the global tuna fishing industry of climate change-driven alterations in productivity and body sizes

Tunas and billfishes are the main large pelagic commercial fish species. Tunas comprised around 5.5 million tonnes and USD 40 billion in 2018. Climate change studies and projections estimate that overall, global fisheries productivity will decrease due to climate change. However, there are seldom projections of the climate-driven productivity of the higher trophic levels where tunas and billfishes belong. In this work, we use a mechanistic model to evaluate the effects of climate change and fishing for globally distributed and commercially exploited seven tuna species and swordfish which are divided into 30 stocks for management purposes, under a range of climate change (RCP 2.6 and 8.5) and fishing scenarios (from no fishing to 1.5 times the fishing mortality (F) at the Maximum Sustainable Yield, FMSY) from two Earth System Models (IPSL and MEDUSA). The results suggest that high trophic level species will be more impacted by climate change than by fishing pressure under the assumption that they remain nearby their MSY levels. However, no-fishing scenarios project much higher biomass. The overall productivity of the target species will decrease by 36% and only the Pacific bluefin showing a slight increase in the future. Five species; Atlantic and Southern bluefins, swordfish, bigeye, and albacore are estimated to decrease in biomass and size at different rates. These species represent almost a third of the landings in the Atlantic Ocean and 10% in the Pacific Ocean being the bluefins, the highest-valued tuna species. On average, the body size is expected to decrease up to 15% by 2050. Fish price and demand are partially driven by body size and therefore, revenues can be reduced even in stocks with an increase in productivity. The fishing industry can adapt to the changing climate by increasing the value of fish through sustainability certifications and reducing fuel consumption and time at sea with higher digitalization. Reducing fuel consumption would also be an additional mitigation measure to climate change since it would reduce CO2 emissions.

Do U.S. consumers value genetically modified farmed salmon?

Genetically modified (GM) salmon is the first animal GM product approved for human consumption. Given that genetic modification in the food industry is a highly controversial issue, understanding consumers’ preferences for GM salmon vis-à-vis non-GM farmed and wild-caught salmon is important to provide insights into food policy decision makings on animal GM products. We use a choice experiment to estimate U.S. consumers’ willingness to pay for GM salmon and examine heterogeneity in preferences across levels of consumer perceptions, knowledge, and attitudes. Our results show that U.S. consumers are willing to pay significantly less for GM salmon than non-GM farmed or wild-caught salmon, suggesting their lower valuation of GM salmon. Heterogeneity exists in the valuation of consumers. Consumers who are more concerned about farmed fish in terms of health and safety, environmental sustainability, and welfare, those who report a higher subjective knowledge of GM, and those having a negative attitude towards GM food and technology place a lower value on GM salmon. Consumers require a larger price discount for GM salmon if the salmon is fresh than frozen. Our study draws policy implications for the competition between salmon industry players and for labeling rules and sustainability certifications of GM salmon.

Sustainability Assessment of Buildings Indicators

The building sector is responsible for a high environmental impact, namely during construction, maintenance, demolition, and lifetime. It is then urgent to develop tools for guiding all stockholders to make buildings more sustainable. In order to make the sustainability assessment of a building, it is necessary to make a survey of the most appropriate parameters for this analysis and organize them hierarchically. The first sustainability certification rating tools were developed in the 90′s of the last century, namely Leadership in Energy and Environmental Design (LEED) and Building Research Establishment Environmental Assessment Methodology (BREEAM), which allow for the quantitative sustainability assessment of different types of buildings. After the first developments, many authors joined in the endeavor of producing easier-to-use and more accurate sustainability assessment systems using sustainability indicators and their respective weights. This work provides a rational pathway throughout the relevant literature on sustainability indicators, comparing indicators proposed by different authors and different sustainability certification systems.

Sustainability labels in the Spanish coffee market: A hedonic price approach

Aim of study: Focused on the coffee sector, the purpose of this paper was to determine the implicit price paid for the main sustainability certifications (Fairtrade, Organic, Rainforest Alliance and UTZ certifications) using the hedonic price approach. Area of study: Spain. Material and methods: The total sample included 645 coffees. The characteristics were collected between the months of September and October 2021 from coffee packs sold in the main five supermarkets of retail chains in Spain. A log-log price/attribute function was used to estimate the hedonic price function. Main results: The attributes UTZ certification, origin, and coffee intensity received significant positive effects leading to higher premium prices of 28.51%, 25.50% and 26.50%, respectively. In contrast, Fairtrade certifications had a negative impact on the average price of coffee. Research highlights: The proposed model could be considered as a first approximation of a hedonic pricing model estimation for sustainable coffee in Spain. The results provide useful information for the coffee sector in developing effective marketing strategies that support the sustainability of food.

Social equity in sustainability certification systems for the built environment: understanding concepts, value, and practice implications

Sustainability certification systems play both an agenda-setting and practical role for a variety of architecture, planning, and engineering project types. The evolution of existing systems and the creation of new certification systems to address a broader set of social sustainability topics provide a unique opportunity to explore the different ways the industry is thinking about and applying social equity ideas to varied projects. We explore this diversity by conducting a content analysis of the guidance documents from eight sustainability certification systems to better understand how social equity is defined, the context in which the concept is applied, and how systems value the idea. The manner and degree to which systems engage with recognitional, procedural, and distributional aspects of social equity varies. Consequently, there is no guarantee that certification leads to real-world equitable outcomes. Moreover, sustainability professionals seeking to use certification systems to address unequal social impacts or benefits still need to bring a clear set of goals regarding equity of what and for whom, as well as ideas of how to measure and evaluate the distribution of social costs/benefits in order to put social equity into practice.

With and beyond sustainability certification: Exploring inclusive business and solidarity economy strategies in Peru and Switzerland

Certification of sustainability standards is an important governance strategy aimed at enhancing the human well-being outcomes of agri-food value chains. While the impacts of certification on well-being are positive for some farmers under certain conditions, they are insignificant or adverse for others. Many barriers can impede positive impacts of certification on well-being. Alternative or complementary strategies such as inclusive business and solidarity economy may challenge these barriers. However, since certification, inclusive business and solidarity economy strategies are studied in isolation, their precise similarities and differences, their interplay and their relative efficacy and limitations remain elusive. Therefore, this paper explores to what extent and how inclusive business and solidarity economy strategies may overcome the persistent governance and economic barriers that limit well-being impacts of certification. We explore four purposively selected cases of inclusive business and solidarity economy strategies from the cacao value chains connecting Peru and Switzerland. Results show that value chain actors combine different specific elements of the three strategies (certification, inclusiveness and solidarity) into portfolios of instruments, which reflect their value chain role and organizational missions. These instrument portfolios may address some of the barriers of certification schemes, but they come with their own challenges and limitations. We conclude that promising future research may use comparative research designs to disentangle specific instruments of inclusiveness, solidarity, and certification; to build typologies of instrument portfolios; to understand their interaction with systemic change in markets and land-use systems; and to specify the conditions under which value chain actors can use specific instruments to improve well-being outcomes of agri-food value chains.

Assessment of the sustainable use of chemicals on a level playing field.

Misleading conclusions can result from applying tools beyond the purposes for which they were designed. A range of chemical assessment systems was compared against a set of principles germane to the sustainable use of chemicals relevant to the whole societal life cycles of finished products. These principles of sustainable use included: wider dimensions of sustainability, a foundation in science, consideration of life-cycle risk rather than simply intrinsic chemical properties, contributions to meeting human needs, open access, and peer review. A transparent basis in science is important for deriving objective, comparable, and replicable sustainability-based findings across materials and applications, and for guiding innovation. Few assessment systems currently identify how use of substances contributes to meeting human needs, a vital albeit often overlooked aspect of sustainable development, with most based largely on potential hazard without addressing wider life-cycle exposure and risk assessment. Qualitatively differing substances were illustratively assessed against the sustainability principles and life-cycle context of the Additive Sustainability Footprint (ASF), aspects of this analysis highlighting how differing material sourcing, manufacturing, and management in-use and at end-of-life can lead to widely divergent sustainability assessments. These illustrative ASF assessments also demonstrate that material use challenges, assessed on a systemic basis, are common across materials, with no defensible automatic assumption that there are inherently "good" or "bad" materials; differing stewardship across whole product life cycles substantially influences sustainability credentials for all materials. It is therefore important that the sustainability performance of all materials is assessed on an objective "level playing field," which also highlights "hot spots" for sustainable innovation from supply-chain management through manufacturing, substance selection by material compounders, maintenance inputs in product use, and beyond product end-of-life. Chemical regulation must evolve to include and embed wider sustainability principles into operational practice and become applicable and enforced across increasingly global value chains.

Developing global supplier competences for supply chain sustainability: The effects of institutional pressures on certification adoption

AbstractDue to institutional pressures faced by companies in their business environment, this paper investigates how sustainability certification adoption affects global suppliers' competences. Using multiple case studies, managers of 20 export‐oriented firms were interviewed, and secondary data were collected and analysed through inductive content analysis. Findings show normative and mimetic pressures as central for sustainability implementation by coffee suppliers. Additionally, we found that as a result of suppliers' sustainability improvement in their own operations, during the certification adoption, new competences emerged going beyond the triple bottom line dimensions, including improvements in aspects of institutional dimension of sustainability. In contrast to previous research in supply chain sustainability that emphasises coercive pressures, this paper demonstrates the role of normative and mimetic institutional pressures in developing new supplier competences. In doing so, we draw on the role of certification adoption in influencing global suppliers and hence sustainability throughout the supply chain.

Toward Regenerative Sustainability: A Passive Design Comfort Assessment Method of Indoor Environment

The fact that people spend a major part of their lifetime indoors, together with the lethal COVID-19 pandemic which caused people to spend even more time inside buildings, has drawn attention to the significance of achieving Agenda 2030 SD goal number three: good health and well-being, in reference to the indoor environment. The research subject is the health and well-being of building users explored through the sustainable (passive) design principles having an impact on the comfort and quality of the indoor environment. It is set within a regenerative sustainability framework encompassing the physiological, biophilic, psychological and social aspects of comfort. The Comfort Assessment Model’s categories, to some extent, rely on the first author’s doctoral thesis, with further modifications regarding the passive design criteria and indicators. A comparative analysis of the model with international sustainability certification (rating) systems has been performed, proving the significance of introducing more passive design comfort (health) related criteria into sustainability assessment models. In addition, a focus group of expert architects contributed to the research conclusions by responding to a questionnaire addressing the issues of sustainability, comfort and passive design, in terms of the health and well-being of building users, which confirmed the relevance of applied passive design measures for providing comfort indoors and fulfilling sustainable development goals.
