The tourism industry contributes eight percent to global carbon emissions, directly and indirectly. Indirect carbon emissions are often neglected because they are difficult to calculate. The traditional approach to calculating indirect emissions – Life Cycle Assessment – is expensive and requires an expert data analyst. We introduce an alternative approach, the Environmentally Extended Input-Output Analysis. We show how this approach – currently used at macro-level to estimate carbon emissions at national or regional level – can be applied to the business level using carbon emissions generated by one hotel room clean as an example. Our comparative analysis shows that Environmentally Extended Input-Output Analysis leads to similar results as Life Cycle Assessment, while being substantially cheaper and more user-friendly. Environmentally Extended Input-Output Analysis, we conclude, enables tourism businesses to estimate the indirect carbon emissions of their operations, which is the key to identifying target areas for improvement.

This study aims to quantify the environmental impact of two retail distribution networks and offer consumers a channel that is more beneficial to the environment. The environmental impact of replenishing the packaged beverages sold in convenience stores (CVSs) and hypermarkets is assessed using the streamlined life-cycle assessment (LCA) approach. In this study, the life-cycle impact assessment (LCIA) for packaged beverages up to the point of sale illustrates the distribution-level environmental impacts of truck transportation. The matched-pair t -test shows that the environmental impacts of transporting 1800 cartons of 24-pack/10 oz. beverages to be sold in Carrefour and 7-11 stores is different at a significance level of 0.1. The transport-focused LCA is used to improve the understanding and compare the environmental characteristics of the two distribution and retail systems. This study constitutes a vehicle for communicating to both internal and external stakeholders the environmental profiles of distributing the same product sold through two retail channels.

Abstract: This study employed a two-phase methodology to assess the environmental impacts from offset lithographic printing on color-box packaging. The Analytic Hierarchy Process (AHP) was used to prioritize improvement options and the life-cycle assessment (LCA) approach was used to assess environmental impacts quantitatively. This study quantified the total amount of energy consumption and CO2 emissions caused by the printing processes of color-box packaging and showed that the total reduction of GHG emissions of the system that omitted the laminating and varnishing process was approximately 239 kg. Moreover, incineration contributes 2905–3004 kg of CO2 to potential global warming in the case of color-box packaging. The study demonstrated the viability of the AHP for evaluating environmental impacts of printing processes, ranking them in order of pollution potential, and subsequently identifying those critical for reducing environmental pollution on the printing operation. This study also showed how the LCA approach may be used together with expert opinion to identify opportunity to alter printing processes in order to address environmental impacts and improve the environmental profile of offset lithographic printing.
