MEXALCA (Modular EXtrapolation of Agricultural LCA) extrapolates crop inventory data and impacts from an original country inventory to all producing countries worldwide. This allows estimates of worldwide means weighted by production volumes and of the environmental impact distribution. In this paper, the relationship between the yield and the environmental impacts is analysed in order to test whether...

Water accounting and environmental impact assessment across the product's life cycle is gaining prominence. This paper presents two case studies of applying the Life Cycle Assessment (LCA) and Water Footprint (WF) approaches to tea and margarine. The WF, excluding grey water, of a carton of 50 g tea is 294 L green water and 10 L blue water, and that of a 500 g tub of margarine is 553 L green water,...

The agri-food sector, and specifically agricultural production, is a major contributor to climate change. In order to manage the impact on the climate, a better understanding of the variability of global warming potential in agriculture is needed. This study assesses the variability in global warming potential of 27 crops using the modular extrapolation of agricultural life cycle assessment (MEXALCA)...

There is an increasing need for life cycle data for bio‐based products, which becomes particularly evident with the recent drive for greenhouse gas reporting and carbon footprinting studies. Meeting this need is challenging given that many bio‐products have not yet been studied by life cycle assessment (LCA), and those that have are specific and limited to certain geographic regions.
In an attempt...
