Reliability of energy-related environmental footprints of products
The focus of this project will be the assessment of the variability of environmental footprints driven by dependencies on consumer behaviours and other factors. These include e.g. shower gel, shampoo and detergents in developed economies (where water is heated before use). Different sources of variability play a role, likely to be a mix of technology-driven (e.g., programmes in a washing machine, machine type and energy system) and consumer behaviour-driven (e.g., programme chosen in the washing cycle, product dosing and showering time) ones. Options to reduce the impacts of such products must address the different sources of uncertainty and variability, and potential trade-offs with other life cycle stages (e.g., impacts during production stages, if new ingredients are developed to allow effective washing at lower temperatures).
