Abstract
This study involved an environmental assessment of retail channels using the simplified life-cycle assessment (LCA) method to quantify the environmental impact of packaged beverages consumed in 7-Eleven convenience stores (c-stores) and Carrefour hypermarkets, with the aim of offering shoppers more environmentally friendly chain stores. The life-cycle impact assessment (LCIA) of packaged drinks at the point of sale (POS) shows the environmental impact of (1) consumer transportation mode and (2) truck distribution. A comparative analysis was conducted on the consumption of 1800 cartons of packaged beverages in c-stores compared to hypermarket channels replenished by individual distribution systems. The paired t-test was used to assess the impact of the consumption of 1800 boxes of 24 packs of 10-ounce drinks. The significance level of the beverages consumed in Carrefour and 7-Eleven c-stores differed by 0.1. The logistics-focused LCA explained the environmental and business rationale for replenishment and sustainable customer transportation. We conclude that, due to consumer preference for retail channels and mode of transport, the carbon footprint for the same products consumed in different channels should not be identical. The research demonstrated a tool to convey more environmental profiles of transportation mode selection to consumers and contribute to building sustainable communities.
Highlights
An increasing number of supply chains are adopting carbon regulatory mechanisms to achieve sustainable development, such as introducing carbon labels on products to indicate the contribution to climate change made by the product throughout its lifespan [1,2]. the carbon dioxide emitted as a byproduct of the manufacture, transport, or disposal of a consumer product is listed on the carbon emission label, should the same products consumed in different retail channels have an identical carbon footprint? Worldwide, consumers buy one million plastic bottles every minute
