Is the green key standard the golden key for sustainability measurement in the hospitality sector?

This article describes a method for promoting sustainable business practices in the hospitality sector and focusses on energy usage in hotels. It raises questions about the actual impact of eco-labels on actual environmental performance.

Introduction: Defining Sustainability

There are many different uses of the term sustainability as well as its derivatives, such as social sustainability, environmental sustainability, sustainable development, sustainable living, sustainable future, and many others. Literally, the word sustainability means the capacity to support, maintain or endure; it can indicate both a goal and a process. In ecology, sustainability describes how biological systems remain diverse, robust, resilient and productive over time, a necessary precondition for the well-being of humans and other species. As the environment and social equality became increasingly important as a world issue, sustainability was adopted as a common political goal. The concept of sustainability the way most of us use it today emerged in the 1960s in response to concern about environmental degradation. This degradation was seen by some to result from the consequences of industrial development, increase in consumption and population growth and by others as poor resource management or the result of underdevelopment and poverty. Sustainability was linked to ethical concerns, typically involving a commitment to justice between generations involving issues such as equal distribution of wealth, working conditions and human rights, and possibly between humans and nonhumans, as discussed in chapters of Robert Garner, Holmes Rolston III and Haydn Washington. We can distinguish between different types of sustainability, for example between social (in terms of promoting equality, health, human rights), economic (in terms of sustaining people’s welfare, equitable division of resources) and environmental (in terms of sustaining nature or natural resources for humans and for nonhuman species) sustainability, as well as combinations of them. The study of sustainability involves multidisciplinary approaches, anthropology, political ecology, philosophy and ethics and environmental science. This type of multidisciplinary combination enables us to explore this new form of institutionalized sustainability science in a neoliberal age of environmental knowledge production and sustainability practice.

Education for the future?

Building on the Millennium Development Goals, Education for Sustainable Development (ESD) and Education for Sustainable Development Goals (ESDG) were established. Despite the willingness of many educational institutions worldwide to embrace the SDGs, given escalating sustainability challenges, this article questions whether ESDG is desirable as “an education for the future”. Many challenges outlined by the SDGs are supposed to be solved by “inclusive” or “sustainable” economic growth, assuming that economic growth can be conveniently decoupled from resource consumption. Yet, the current hegemony of the sustainability-through-growth paradigm has actually increased inequalities and pressure on natural resources, exacerbating biodiversity loss, climate change and resulting social tensions. With unreflective support for growth, far from challenging the status quo, the SDGs and consequently, the ESDGs, condone continuing environmental exploitation, depriving millions of species of their right to flourish, and impoverishing future generations. This article creates greater awareness of the paradoxes of sustainable development and encourages teaching for sustainability through various examples of alternative education that emphasizes planetary ethic and degrowth. The alternatives include Indigenous learning, ecopedagogy, ecocentric education, education for steady-state and circular economy, empowerment and liberation. “This is an Accepted Manuscript of an article published by Taylor & Francis in 'Journal of Environmental Education' on 01/20/20, available online: https://www.tandfonline.com/doi/full/10.1080/00958964.2019.1710444 LinkedIn: https://www.linkedin.com/in/helenkopnina/

Tourism life cycle assessment (LCA) : proposal of a new methodological framework for sustainable consumption and production

Extending the scope of eco-labelling in the food industry to drive change beyond sustainable agriculture practices

New consumer awareness is shifting industry towards more sustainable practices, creating a virtuous cycle between producers and consumers enabled by eco-labelling. Eco-labelling informs consumers of specific characteristics of products and has been used to market greener products. Eco-labelling in the food industry has yet been mostly focused on promoting organic farming, limiting the scope to the agricultural stage of the supply chain, while carbon labelling informs on the carbon footprint throughout the life cycle of the product. These labelling strategies help value products in the eyes of the consumer. Because of this, decision makers are motivated to adopt more sustainable models. In the food industry, this has led to important environmental impact improvements at the agricultural stage, while most other stages in the Food Supply Chain (FSC) have continued to be designed inefficiently. The objective of this work is to define a framework showing how carbon labelling can be integrated into the design process of the FSC. For this purpose, the concept of Green Supply Chain Network Design (GSCND) focusing on the strategic decision making for location and allocation of resources and production capacity is developed considering operational, financial and environmental (CO2 emissions) issues along key stages in the product life cycle. A multi-objective optimization strategy implemented by use of a genetic algorithm is applied to a case study on orange juice production. The results show that the consideration of CO2 emission minimization as an objective function during the GSCND process together with techno-economic criteria produces improved FSC environmental performance compared to both organic and conventional orange juice production. Typical results thus highlight the importance that carbon emissions optimization and labelling may have to improve FSC beyond organic labelling. Finally, CO2 emission-oriented labelling could be an important tool to improve the effects eco-labelling has on food product environmental impact going forward.
