Abstract Fodder for feeding pork and poultry requires a large amount of cultivated and processed agricultural crops, which are often related to greenhouse gas emissions from land-use change (LUC). Given the rapid growth in meat production in Brazil for domestic consumption and international export, the link between LUC emissions and consumption of pork and poultry meat is central to evaluating the role of Brazilian meat production and the implications for international climate policies. In this paper, we first estimate LUC emissions from soybean production destined to feed pork and poultry in Brazil during the period 2008–2012. Second, we allocate such emissions to domestic and international consumption of pork and poultry meat. Concerning international consumption, Brazilian export of meat to 189 countries is evaluated. Although the majority of the LUC emissions from soybean production are tied to the domestic consumption, 17% and 39% of the emissions embodied in Brazilian pork and poultry, respectively, are exported to other countries. The most prominent destinations of Brazilian pork and poultry in terms of embodied LUC emissions are Eastern Europe, Asia and South America. In the case of pork, the fluxes of emissions from Brazil to Ukraine (1.28 Mt CO2-eq) and Russia (1.18 Mt CO2-eq) are particularly large. In the case of poultry, the largest transfers of embodied emissions are from Brazil to developing countries and especially the Middle East. These results are relevant to environmental policies and international agreements aimed at achieving the sustainability of Brazil's meat sector.

Questions of justice in the transition to a green economy have been raised by various social forces. Very few proposals, however, have been as focused and developed as the “just transition” strategy proposed by global labour unions. Yet, labour unions are remarkably absent from discussions of the transition towards a green economy. This is surprising as labour unions are arguably the largest organizations in the world fighting for basic rights and more just social relations. This paper tries to advance the potential contribution of labour unions in this arena by asking: what is the full scope of “just transition” today and how have labour unions developed and refined it over the years to render the move towards a green economy both environmentally and socially sustainable? The concept of just transition is hotly debated within labour unions and has different interpretations, and hence different strategies. The last section assesses these interpretations by means of a normative framework, which seeks to fuse political economy and political ecology. Empirically, we add to the growing literature on labour environmentalism, as well as transitions more generally. Analytically, our goal is to place the various approaches to a “just transition” within a heuristic framework of environmental justice that is explicit about power relations when demanding justice, two themes central to this special issue.

The implementation of resource management strategies aimed at reducing the impacts of the anthropogenic activities system requires a comprehensive approach to evaluate on the whole the environmental burdens of productive processes and to identify the best recovery strategies from both an environmental and an economic point of view. In this framework, an analytical methodology based on the integration of Life Cycle Assessment (LCA), ExternE and Comprehensive Analysis was developed to perform an in-depth investigation of energy systems. The LCA methodology, largely utilised by the international scientific community for the assessment of the environmental performances of technologies, combined with Comprehensive Analysis allows modelling the overall system of anthropogenic activities, as well as sub-systems, the economic consequences of the whole set of environmental damages. Moreover, internalising external costs into partial equilibrium models, as those utilised by Comprehensive Analysis, can be useful to identify the best paths for implementing technology innovation and strategies aimed to a more sustainable energy supply and use. This paper presents an integrated application of these three methodologies to a local scale case study (the Val D'Agri area in Basilicata, Southern Italy), aimed to better characterise the environmental impacts of the energy system, with particular reference to extraction activities. The innovative methodological approach utilised takes advantage from the strength points of each methodology with an added value coming from their integration as emphasised by the main results obtained by the scenario analysis.

Abstract The management of failure analysis has a strategic importance within a refinery from the organizational, engineering and economic point of view. The determination of an algorithm, that allows a methodical and as far as possible automatic approach to management of failure data, can make substantial improvements in the organization of work and in the decision-making processes. A panel of expert, made up of academicians and refinery operators, was formed in order to develop a Risk-Based Inspection and Maintenance (RBI&M) procedure. RBI&M procedure developed comprises six modules: identification of the scope, functional analysis, risk assessment, risk evaluation, operation selection and planning, J-factor computation and operation realization. Taking into consideration historical data regarding Near Accidents, Operating Drawbacks, Occupational and Environmental Accidents occurred in refinery over the last years the panel of expert defined a risk matrix in order to evaluate the risk associated to critical events and maintenance activities. Five probability classes and five severity categories, that take into account four impact categories (Health and Safety, Environmental, Economic and Reputation), have been defined. This paper reports the application of the RBI&M method to two specific stages in the maintenance activities of the refinery, i.e. the oil refinery turnaround and work orders management. The panel of expert developed heuristic methods in order to apply RBI&M procedure to the two cases allowing the refinery to minimize the overall risk taking into consideration the limits in term of time and budget (in turnaround case) and of human resources (in the management of work orders). The results have highlighted a clear improvement in the indices which measure the quality of maintenance.

Agroforestry is considered a sustainable form of land management that optimizes the use of natural resources (nutrients, radiation, water). Agroforestry is defined as the deliberate integration of woody vegetation with agricultural activities in the lower story. It provides a higher biomass production per unit of land, while providing more ecosystem services than woody-less agricultural lands, such as the reduction of soil erosion and nitrogen leaching, and increase carbon sequestration and landscape biodiversity. The objective of this paper is to evaluate the past and current European Union Common Agricultural policies aiming at promoting the afforestation or reforestation of lands, as the introduction of trees can be seen as a first step to carry out agroforestry practices in former agricultural or forest lands. Agroforestry was a traditional land use system in Europe before modern times. However, before the sixties land intensification and consolidation destroyed millions of trees all over Europe. On the contrary, some good examples of agroforestry promotion are found in Eastern European countries in order to reduce the effect of extreme events such as winds, flooding at the beginning and mid of the last century. In Western European countries, the introduction of trees in the land has been promoted by agroforestry, afforestation and reforestation at the end of the last century. Afforestation of agricultural lands have been the most successful CAP measure (over 1 million hectares) while agroforestry measures were not extensively adopted which may be explained by the funds associated to afforestation measure which compensated the losses of income 15 or 20 years in afforested lands. Agroforestry was poorly adopted in the CAP 2007-2013, having a better success in the CAP 2014-2020 due to the recognition of woody vegetation and the compensation of 5 years given for maintenance once agroforestry is established. However, policy rules ensuring Pillar I payment when agroforestry measure is adopted such as a management plans ensuring that maximum tree density (100 trees per hectare) is not reached, should be pursued.

Sustainability has become a central issue for firms in the energy industry. These firms have been under increasing pressure to uplift not only their environmental consciousness but also social impact of their actions. One constraint of these firms is prevention of trading off shareholder value maximization with increasing their corporate social responsibility activities geared to the long term benefits of stakeholders. Based on the principles of fairness and equity, Islamic Banking and Finance also provides a vehicle for the firms in the energy industry by incentivizing their corporate social responsibility activities.

Abstract Economic development in agriculture is often accompanied by strong environmental pressures that present risks, which could lead to irreversible damage of the associated agro-ecosystem. A form of agricultural management that utilizes natural resources rationally yet maintains ecological stability is necessary. Ecologically sound, yet productive, use of resources requires indicators that assess not only productive and economic factors, but also environmental impact and ecological effects. Thus, to study an agricultural activity and its interaction with the environment, a holistic approach, capable of considering ecological, biophysical and socio-economic aspects is appropriate. Here we use emergy analysis and its indicators as given in Odum (Science 242 (1988) 1132–1139), to evaluate how sustainability of a soybean crop in south Tuscany (Italy) is increased using the specific bacteria inoculation to satisfy, through fixation, the nitrogen need of the crop. Cultivation was studied with two options: (1) utilization of chemical fertilizers to supply nitrogen needs as often done in the past, and as a viable present alternative and (2) the symbiotic activity of Bradyrhizobium bacteria, given as inoculum, to cover all nitrogen needs. This article shows that proper agricultural management should help maintain, and increase, system capacity, i.e. the quality of the system environment (soil, water,…), to sustain biomass, and prevent environmental degradation. For an Italian agro-ecosystem, the results demonstrate that agricultural production is more than doubled and the use of non-renewable and toxic inputs, such as chemical fertilizers, is reduced by use of the inoculum. The good results for soybean suggests development of analogous cultivation methods for other agricultural species, such as gramineous, for which different N-fixing bacteria such as Azospirillum, have been already identified.
