| الوصف: | Climate change mitigation involves changes in production and consumption ways to boost a radical decrease in Greenhouse Gases (GHG) emissions, which come mostly from fossil fuels combustion. To meet these challenges, a lot of countries initiated an energy transition to switch to new energy system, especially concerning electricity production, in such a way that they partly fulfil low carbon economy requirements. To provide decision-makers guidance in their strategic choices, decision-aid tools are useful to identify and reduce environmental impacts burdens. In particular, Life Cycle Assessment (LCA) which assesses environmental impacts throughout a product's life cycle is now a recognized and standard approach. Consequential LCA (cLCA), one of its most recent developments, assesses changes consequences considering either direct or indirect effects on environment. Currently, due to the lack of generic consequential Life Cycle Inventories (LCI), cLCA is scarcely used by practicioners. This situation is emphasized for electricity, due to its large involvement in technosphere and its shifts to production modes in the context of energy transition. This work aims at the development of a design methodology for generic inventories for consequential LCA, taking in account electricity technical specificities. Electricity is defined here as a different production means combination (a “mix”) which varies from country to country. To simplify electricity production mix, a typology is set using a GHG emissions study and electricity mix separation in production means. The typology identifies four groups, ranked by increasing GHG emissions, i.e, 0-37 gCO2eq/kWh, 37-300 gCO2eq/kWh, 300-600 gCO2eq/kWh and >600 gCO2eq/kWh, and specific compositions. Considering a consequential perspective, an evolution analysis of twelve selected countries from 1960 to 2010 is then conducted. Thus, an analysis of past transitions, i.e., shifting from a group to another, is given. Amono-objective optimisation model is developed, involving, first, ... |
