Increasing interest in biofuels trade between developed and developing countries has spurred worldwide discussions on issues such as subsidies and the ‘food for fuel’ crisis. One issue missing in recent discourse is the pressure exerted on developing countries to adopt large-scale mechanized farming practices to increase economic efficiencies. Such approaches often exclude small-scale farmers from participating in the emerging biofuels market, thus exacerbating poverty and social exclusion. Drawing on both qualitative and technical data, we discuss such pressures using Brazilian ethanol and biodiesel production. Pressure from international markets to become more economically efficient may contribute towards the erosion of recent schemes to encourage social benefits for small farmers in biodiesel production. We conclude with trade and policy implications.

Este trabalho analisa a evolução de cinco distribuidoras de energia elétrica, localizadas no Nordeste do Brasil, por meio de indicadores técnicos e financeiros. Três empresas privatizadas e duas públicas foram analisadas entre 1997 e 2008. Os indicadores financeiros mostram a lucratividade e capacidade de as firmas gerarem valor para os acionistas, enquanto os técnicos a qualidade do serviço prestado aos consumidores. Duas proposições foram estabelecidas sugerindo que as empresas privatizadas tiveram seus indicadores financeiros e técnicos melhorados, comparativamente às empresas públicas, depois da privatização. Observou-se que os indicadores financeiros das distribuidoras privatizadas melhoraram em relação aos das públicas, gerando mais valor para seus acionistas. No entanto, não há evidência de que a privatização impactou na melhoria dos indicadores técnicos e qualidade do serviço.

Few sectors in the global economy need deep decarbonization as much as heavy industry, which is currently the largest and fastest growing source of global carbon emissions. Based on an original dataset of 111 expert interviews and 52 site visits, this paper asks: what sociotechnical pathways, capabilities, and regional innovation systems are emerging to support industrial decarbonization? It combines and applies insights from evolutionary economic geography and transitions studies, such as sociotechnical capabilities and learning, as well as spatial frameworks such as challenge-oriented regional innovation systems (CoRIS) and green industrial restructuring. It utilizes these collective concepts of pathways, capabilities and CoRIS to explore the organizational and technological, individual, and systems level dimensions of industrial decarbonization efforts ongoing across Great Britain. We find that within industrial net-zero clusters, spatial and technological proximities are being effectively leveraged, especially through new forms of networking, collaboration, and partnerships. CoRIS provides the basis for greater reflection on perennial transitions issues, both within and across clusters, related to incumbency and innovation, in addition to spotlighting emergent issues such as light versus deep green restructuring and incremental versus transformative change. In simpler terms, industrial decarbonization unfolds as a multi-scalar process. Industrial decarbonization exhibits both incremental and transformative patterns of change. Industrial decarbonization lastly involves dynamic processes that coevolve across a spectrum of sociotechnical attributes.

PurposeThis paper aims to explore three operations and supply chain management (OSCM) approaches for meeting the 2 °C targets to counteract climate change: adaptation (adjusting to climatic impacts); mitigation (innovating towards low-carbon practices); and carbon-removing negative emissions technologies (NETs). We suggest that adaptation nor mitigation may be enough to meet the current climate targets, thus calling for NETs, resulting in the following question: How can operations and supply chains be reconceptualized for NETs?Design/methodology/approachWe draw on the sustainable supply chain and transitions discourses along with interview data involving 125 experts gathered from a broad research project focused on geoengineering and NETs. We analyze three case studies of emerging NETs (biochar, direct air carbon capture and storage and ocean alkalinity enhancement), leading to propositions on the link between OSCM and NETs.FindingsAlthough some NETs are promising, there remains considerable variance and uncertainty over supply chain configurations, efficacy, social acceptability and potential risks of unintended detrimental consequences. We introduce the concept of transformative OSCM, which encompasses policy interventions to foster the emergence of new technologies in industry sectors driven by social mandates but lack clear commercial incentives.Originality/valueTo the best of the authors’ knowledge, this paper is among the first that studies NETs from an OSCM perspective. It suggests a pathway toward new industry structures and policy support to effectively tackle climate change through carbon removal.

This paper analyzes the evolution of five electricity distribution companies in the Northeast of Brazil using technical and financial indicators. Three privatized and two public firms were analyzed between 1997 and 2008. The financial indicators are used as proxies for the capacity of the business to generate value for shareholders, while the technical indicators are used as proxies for service quality provided to consumers. We observed that the privatized firms had their financial indicators improved after privatization, increasing the value of the firm for the shareholders. However, there is no evidence that privatization affected the quality of service provided to consumers.

We propose reforming the Brazilian regulatory safety framework (BRSF) for offshore oil and gas production and drilling operations. Brazil has emerged as a leading offshore producer with extensive proven reserves yet to be exploited. However, the BRSF has not been updated since 2007, and there are now major concerns about the industry׳s safety, particularly after the BP Deepwater Horizon accident, along with the technical challenges due to extreme conditions under which Brazil׳s resources are located. Drawing on experiences from three leading offshore oil and gas producers (Norway, the UK, and the US), we recommend the adoption of three best practices: the UK׳s ‘safety case’ approach (where operators are expected to provide convincing and valid arguments that a system is sufficiently safe for a given application in a specific environment), Norway׳s ‘barrier management’ (evidence that there are at least two tested and independent barriers to avoid accidents) and greater investment in safety research and development, as suggested by the US׳s National Commission on the BP Deepwater Horizon Oil Spill and Offshore Drilling. We discuss implications for policy reform and how best practices can be applied within the Brazilian context.
