Use of life cycle assessment methodology in the analysis of ecological footprint assessment results to evaluate the environmental performance of universities

The assessment of the environmental performance of an organization is an essential part of the decision making process of an Environmental Management System. Having robust indicators enables a reliable assessment. The Ecological Footprint Assessment is used in different types of organizations, including universities. Its ability to clearly communicate over-consumption by using a land-base unit is an advantage when involving the university community in achieving better environmental performance. However, its lack of standardization makes it difficult to use as an indicator. It is believed that Life Cycle Assessment offers a framework with which to standardize the Ecological Footprint Assessment. In this paper, an Ecological Footprint Assessment considering Life Cycle Assessment methodology is developed as a case study for Universitat Politecnica de Valencia. Findings regarding the critical decisions of the methodology are compared with 23 Ecological Footprint Assessments of universities using a Life Cycle Assessment framework. Only 26% of the studies analyzed reference the Life Cycle Assessment methodology. Critical decisions such as defining a Functional Unit were relevant but not standardized, while the definition of the product system was the most standardized and homogeneous decision. The difficulty of gathering information when Environmental Management Systems are not available makes the Ecological Footprint Assessment a weak indicator. Nevertheless, results show that Life Cycle Assessment can guide an Ecological Footprint Assessment methodology where comparability and reliability is possible. (C) 2016 Elsevier Ltd.

Sustainable design of biorefinery processes: existing practices and new methodology

Nowadays, eco-designing products is increasingly practiced. The next challenge for sustain- ability is to optimize production processes. Biorefi neries are particularly concerned with this improve- ment, because they use renewable resources. To identify the contribution of transformation processes to the overall environmental impacts, Life Cycle Assessment (LCA) appears as the adequate method. A literature review highlights that LCA is mainly performed on biorefi neries to compare biomass feed- stocks between them and to a fossil reference. Another part of environmental LCA compares the impacts of different processing routes. Nevertheless, these evaluations concern already designed pro- cesses. Generally, processes are considered as a unique operation in assessments. However, some criteria like operating can notably modify environmental burdens. The eco-design of biorefi nery pro- cesses can be guided by coupling process simulation to LCA. This method has been emerging in the chemical sector in recent years. Consequently, this paper proposes a new methodological approach to assessing the complete sustainability of biorefi nery processes, since its fi rst design stages. In addi- tion to coupling process simulation and environmental LCA, the other pillars of sustainability will be assessed. Indeed, Life Cycle Costing and Social Life Cycle Assessment can be performed to obtain an integrated methodological framework. The simultaneous optimization of the environmental, economic, and social performances of the process can lead to antagonist ways of improving. Consequently, compromises should be realized. Thereby, the multi-objective optimization can be accomplished by a metaheuristic method supported by a decision-making tool. Finally, the main limits of this method and some perspectives and ways for improving are discussed

Greenhouse gas emissions from a Western Australian finfish supply chain

Greenhouse gas (GHG) emissions in the form of carbon dioxide equivalent (CO2 - eq) from two Western Australian finfish supply chains, from harvest to retail outlet, were measured using streamlined life cycle assessment methodology. The identification of interventions to potentially reduce the GHG emissions was determined from the results obtained. Electricity consumption contributed to the highest GHG emissions within the supply chains measured, followed by refrigeration gas leakage and disposal of unused fish portions. Potential cleaner production strategies (CPS) to reduce these impacts included installing solar panels, recycling the waste, good housekeeping in refrigeration equipment maintenance, and input substitution of refrigeration gas. The results show a combination of these strategies have the potential to reduce up to 35% of the total GHG emissions from fillet harvest, processing and retail

Global Sustainability Under Uncertainty: How Do Multinationals Craft Regulatory Policies?

Multinational corporations are increasingly mindful of the significance of sustainability transitions and the need for operations that are energy efficient and environmentally sound. Achieving sustainability under conditions of uncertainty entails the involvement of multiple stakeholders in initiating and carrying outsustainability-focused initiatives. Using longitudinal analysis of Royal Dutch Shell’s sustainability policies, we developed an integrated model to elucidate how uncertainty influences sustainability policies in the specific context of multinational corporations (hereinafter – MNCs). We identified three phases in theevolution of Shell’s sustainability innovation: a self-reflective phase (2000–2003) characterized by intense pressure from climate advocacy groups, an investment phase (2004–2006) for which the MNC attempted to rise to the waste disposal and pollution challenge through renewable sources of energy, and a reorganization phase (2007–2010) to streamline operations. We also uncovered themes that influence how regulatory policies are crafted: responding positively to the “community’s voice”, risk spreading through joint ventures, revenue transparency for government accountability and reporting innovation that confronts hard truths. The practical implications are outlined
