Mensuração da ecoeficiência das micro e pequenas empresas da cadeia produtiva do petróleo e gás potiguar, com uso da taxonomia CE7. 2017. 166f. Tese (Doutorado em Ciência e Engenharia de Petróleo) - Centro de Ciências Exatas e da Terra, Universidade Federal do Rio Grande do Norte, Natal, 2017.https://repositorio.ufrn.br/jspui/handle/123456789/24150This thesis contribute to studies on environmental sustainability in the oil industry by measuring the eco-efficiency of Small Business of Supply chain oil and gas in Rio Grande do Norte. It also seeks to help maximize environmental efficiency, cost reduction, identification of method improvements in operational processes, adding value and strengthening business competitiveness in the region. Eco-efficiency is a management strategy that aims to reduce resource consumption, reduce the impact on nature and provide customers with higher quality products and services. For its measurement, we used the methodology called CE7 taxonomy, an acronym referring to the "seven competences of ecoefficiency" that, when adapted to the environmental strategies to support eco-efficiency, it will show the level of eco-efficiency in which companies are. We analyzed 44 (forty-four) Small business of the oil and gas production chain of Rio Grande do Norte, which works for Petrobras and are part of RedePetro RN. These companies are also part of the project "RN oil, gas and energy production chain" developed by SEBRAE-RN. We collected data from August to October 2016, using the survey method. At the end of the study it was evidenced the absence of eco-efficient Small business in the productive chain and that the best results occurred for 15.91% companies that obtained a level of "almost" eco-efficiency. The environmental strategies that promote eco-efficiency are energy efficiency, Solid Waste Management Plan (SWMP), environmental caution in supplier selection and environmental licensing. Finally, eco-efficiency is not an institutionalized management practice in the small business of this productive chain.Acesso AbertoGestão ambientalSustentabilidadeEcoeficiênciaCadeia produtiva do petróleodoctoralThesisCNPQ::ENGENHARIAS::ENGENHARIA QUIMICA::TECNOLOGIA QUIMICA::PETROLEO E PETROQUIMICA
