In recent years, increased light has been shed on the large amounts of food wasted along the food supply chain (FSC). As lifecycle assessments (LCAs) are commonly used for estimations of environmental impacts from food production, it is relevant to investigate and discuss how such wastage is reflected in foodstuff LCAs. The objective of the present paper is to review a larger set of LCAs of foodstuff in order to (1) investigate if and how wastage along the FSC is addressed and (2) explore the importance of including wastage accumulated along the FSC in terms of environmental impacts. Twenty-eight LCA case studies and two review papers, focusing on tomatoes, were reviewed and greenhouse gas (GHG) emissions chosen as indicator for the second objective. Only one third of the studies consider wastage at some part of the supply chain, in many cases in an inconsistent manner, and only in nine cases were GHG emissions from wastage included in overall systems GHG emissions. In these, wastage accounts for between 2 and 33% of total contribution to climate change. Omitting wastage when conducting LCA of foodstuff could result in underestimations of environmental impacts. Occurrence of wastage along all phases of the supply chain should be acknowledged in order to estimate environmental benefits from prevention and to identify areas where strategies with the aim of reducing wastage could be most efficient.

This paper provides a review of an emerging field in the food processing sector, referring to efficient and safe food supply chains, ’from farm to fork’, as enabled by Artificial Intelligence (AI). The field is of great significance from economic, food safety and public health points of views. The paper focuses on effective food production, food maintenance energy management and food retail packaging labeling control, using recent advances in machine learning. Appropriate deep neural architectures are adopted and used for this purpose, including Fully Convolutional Networks, Long Short-Term Memories and Recurrent Neural Networks, Auto-Encoders and Attention mechanisms, Latent Variable extraction and clustering, as well as Domain Adaptation. Three experimental studies are presented, illustrating the ability of these AI methodologies to produce state-of-the-art performance in the whole food supply chain. In particular, these concern: (i) predicting plant growth and tomato yield in greenhouses, thus matching food production to market needs and reducing food waste or food unavailability; (ii) optimizing energy consumption across large networks of food retail refrigeration systems, through optimal selection of systems that can be shut-down and through prediction of the respective food de-freezing times, during peaks of power demand load; (iii) optical recognition and verification of food consumption expiry date in automatic inspection of retail packaged food, thus ensuring safety of food and people’s health.

Potential environmental benefits have been identified for the utilization of carbon dioxide (CO2) as a feedstock for polyurethanes (PUR). CO2 can be utilized in the PUR supply chain in a wide variety of ways ranging from direct CO2 utilization for polyols as a PUR precursor, to indirect CO2 utilization for basic chemicals in the PUR supply chain. In this paper, we present a systematic exploration and environmental evaluation of all direct and indirect CO2 utilization options for flexible and rigid PUR foams. The analysis is based on an LCA-based PUR supply chain optimization model using linear programming to identify PUR production with minimal environmental impacts. The direct utilization of CO2 for polyols allows for large specific impact reductions of up to 4 kg CO2-eq. and 2 kg oil-eq. per kg CO2 utilized, but the amounts of CO2 that can be utilized are limited to 0.30 kg CO2 per kg PUR. The amount of CO2 utilized can be increased to up to 1.7 kg CO2 per kg PUR by indirect CO2 utilization in the PUR supply chain. Indirect CO2 utilization requires hydrogen (H2). The environmental impacts of H2 production strongly affect the impact of indirect CO2 utilization in PUR. To achieve optimal environmental performance under the current fossil-based H2 generation, PUR production can only utilize much less CO2 than theoretically possible. Thus, utilizing as much CO2 in the PUR supply chain as possible is not always environmentally optimal. Clean H2 production is required to exploit the full CO2 utilization potential for environmental impact reduction in PUR production.

Globally, the building sector is responsible for more than 40% of energy use and it contributes approximately 30% of the global Greenhouse Gas (GHG) emissions. This high contribution stimulates research and policies to reduce the operational energy use and related GHG emissions of buildings. However, the environmental impacts of buildings can extend wide beyond the operational phase, and the portion of impacts related to the embodied energy of the building becomes relatively more important in low energy buildings. Therefore, the goal of the research is gaining insights into the environmental impacts of various building strategies for energy efficiency requirements compared to the life cycle environmental impacts of the whole building. The goal is to detect and investigate existing trade-offs in current approaches and solutions proposed by the research community. A literature review is driven by six fundamental and specific research questions (RQs), and performed based on two main tasks: (i) selection of literature studies, and (ii) critical analysis of the selected studies in line with the RQs. A final sample of 59 papers and 178 case studies has been collected, and key criteria are systematically analysed in a matrix. The study reveals that the high heterogeneity of the case studies makes it difficult to compare these in a straightforward way, but it allows to provide an overview of current methodological challenges and research gaps. Furthermore, the most complete studies provide valuable insights in the environmental benefits of the identified energy performance strategies over the building life cycle, but also shows the risk of burden shifting if only operational energy use is focused on, or when a limited number of environmental impact categories are assessed.

Green information technology systems (Green ITS) are proposed as a strategy to reduce greenhouse gases (GHGs) emissions and other environmental impacts while supporting ecological sustainable development. The Green ITS concept combines both Green information technology (IT) and Green information system (IS) applications. The Green ITS concept has the potential to combat the carbon emission problem globally, beyond simply Green IT, because it combines management, organizational, and technology dimensions of climate change mitigation and adaptation, especially if supported by global policy. Examples include life cycle assessment software for measuring GHG emissions, and software for monitoring GHG emissions. Previous studies on environmental burdens such as GHGs, water and air pollution, energy losses and other forms of waste alongside socio-economic dependent variables including renewable resources and climate change policies are reviewed and synthesized. The research analysis conjointly points to the usage of renewable resources such as solar and wind as a critical strategy to scale back GHG emissions and enhance green growth. Empirical evidence shows that developed countries can reduce their carbon emissions while developing countries can utilize carbon emission-free technologies as they aspire to achieve development. The two significant benefits of the Green ITS strategy are first, to provide the environmental benefits of reducing greenhouse emissions and other environmental impacts and second, to enhance global green growth, which supports achievement of ecological sustainable development. Green ITS tools support achievement of the UN SDG 7, 13 and 15, which emphasize clean energy, climate action and ecological sustainable development, respectively. Future research directions include the formulation of a strategy to combat GHGs and design of a system to monitor carbon emissions and other waste remotely.

<p>The majority of global food production, as we know it, is based on agricultural practices developed within stable Holocene climate conditions. Climate change is altering the key conditions for human societies, such as precipitation, temperature and aridity. Their combined impact on altering the conditions in areas where people live and grow food has not yet, however, been systematically quantified on a global scale. Here, we estimate the impacts of two climate change scenarios (RCP 2.6, RCP 8.5) on major population centres and food crop production areas at 5 arc-min scale (~10 km at equator) using Holdridge Life Zones (HLZs), a concept that incorporates all the aforementioned climatic characteristics. We found that if rapid growth of GHG emissions is not halted (RCP 8.5), in year 2070, one fifth of the major food production areas and one fourth of the global population centres would experience climate conditions beyond the ones where food is currently produced, and people are living. Our results thus reinforce the importance of following the RCP 2.6 path, as then only a small fraction of food production (5%) and population centres (6%) would face such unprecedented conditions. Several areas experiencing these unprecedented conditions also have low resilience, such as those within Burkina Faso, Cambodia, Chad, and Guinea-Bissau. In these countries over 75% of food production and population would experience unprecedented climatic conditions under RCP 8.5. These and many other hotspot areas require the most urgent attention to secure sustainable development and equity.</p>

As efforts continue to incorporate environmental sustainability into product design, struggles persist to concurrently consider the environmental impacts resulting from transportation planning and supply chain network design. In fact, the transportation sector is the second largest contributor to direct greenhouse gas (GHG) emissions in the United States, following electricity generation. To address these concerns and consider environmental issues more holistically during the development of products, Design for X (X: manufacturing, environment, etc.) methods, such as environmentally benign manufacturing (EBM) and life cycle assessment (LCA) continue to be advanced through research. In spite of improving environmental performance through design, supply chain related impacts are not well understood and can be impacted by decisions made during product design. Thus, the aim of this research is to explore how changes to the design of a product affect manufacturing supply chain configurations and, in turn, influence product environmental sustainability. The environmental impacts for producing several three-ring binder design variations are predicted by assuming a given set of suppliers that provide materials and components to the manufacturer. Supply chain transportation impacts are also accounted for in the analysis. Transportation impacts are found to be minor compared to materials and manufacturing impacts.

Coronavirus had been in existence for many years, but its effects has not been so evident as the whole world experienced recently. It represents an unprecedented emergency and grave societal threat. The better way to cure the emergence disease is by protecting public health. However, governments, policy makers and the international community must quickly need to act, recognize and attempt to mitigate the negative impacts (current and potential) of the pandemic and related response efforts on key sectors that contribute to food security, nutrition and livelihoods. The livestock sector is a key contributor to these areas, especially for the world's most vulnerable populations. In the light of recent challenges in food supply chain, there is now considerable concern about the food production, processing, distribution, and demand. COVID-19 resulted in the movement restrictions of workers, changes in demand of consumers, closure of food production facilities, restricted food trade policies and financial pressures in food supply chain. The effects of COVID-19 on the livestock sector are still largely unquantified and yet to be fully felt. Formal assessments have not yet been possible, but current observations reveal disruptions to livestock value chains. Lessons from past epidemics indicate these disruptions are likely to grow, along with their dire, socio- economic consequences. Moreover, considering the doubt on how these factors will play out in various areas affected especially meat processing and distribution in the years to come from the bulk of discussion in this review.     Le coronavirus existait depuis de nombreuses années, mais ses effets n'ont pas été aussi évidents que le monde entier l'a récemment expérimenté. Cela représente une urgence sans précédent et une grave menace pour la société. La meilleure façon de guérir la maladie émergente est de protéger la santé publique. Cependant, les gouvernements, les décideurs et la communauté internationale doivent rapidement agir, reconnaître et tenter d'atténuer les impacts négatifs (actuels et potentiels) de la pandémie et des efforts de riposte connexes sur les secteurs clés qui contribuent à la sécurité alimentaire, à la nutrition et aux moyens de subsistance. Le secteur de l'élevage est un contributeur clé dans ces domaines, en particulier pour les populations les plus vulnérables du monde. À la lumière des défis récents de la chaîne d'approvisionnement alimentaire, la production, la transformation, la distribution et la demande des aliments suscitent désormais des i nquiétudes considérables. Le COVID-19 a entraîné des restrictions de mouvement des travailleurs, des changements dans la demande des consommateurs, la fermeture des installations de production alimentaire, des politiques commerciales restreintes et des pressions financières dans la chaîne d'approvisionnement alimentaire. Les effets du COVID-19 sur le secteur du bétail sont encore largement non quantifiés et ne sont pas encore pleinement ressentis. Les évaluations formelles n'ont pas encore été possibles, mais les observations actuelles révèlent des perturbations dans les chaînes de valeur de l'élevage. Les leçons des épidémies passées indiquent que ces perturbations sont susceptibles de se développer, ainsi que leurs conséquences socio- économiques désastreuses. De plus, la prise en compte du doute sur la manière dont ces facteurs joueront dans divers domaines touchés, en particulier la transformation et la distribution de la viande dans les années à venir, constitue l'essentiel de la discussion dans cette revue.
