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.

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.

This study, part of an R&D project with Dutch tour operators, assessed Dutch consumer preferences towards a carbon label for holiday trips. A general survey (n = 504) assessed the perceived importance of a CO 2 label to consumers. To determine the preferred design, two focus groups (n = 15) followed by a panel study (n = 1246) were performed. Finally, a pilot study (n = 100) assessed potential effects of the label on attitude and booking intention. The general survey's results indicate that a carbon label could impact on the travel choice of some Dutch travellers, when label information is explicit, understandable and simply designed. The focus groups in combination with the panel study showed that Dutch consumers prefer a recognisable carbon label, similar to the EU energy label. The pilot study revealed that consumers' attitudes increased significantly, but that intention to book was not significantly affected for the group that was shown the carbon label. These findings contribute to understanding consumer attitudes towards tourism eco and carbon labels, and their content and design. Implementation of a carbon label for tour packages still requires a number of barriers to be resolved. Sustainability remains a low priority during holiday decision-making.
