QuantiGES is a method developed by ADEME, to easily quantify and communicate on the outcomes of specific actions in terms of GHG reductions. This method is based on a monocriterion assessment (GHG impacts). For instance, it can be used to quantify the emissions reduction from implementing a new product design compared to a reference one (previous version). Through the creation of a consequence tree, QuantiGES enables you to assess the direct and indirect outcomes of your decisions.
QuantiGES can be used at different stages, from early design phases to communication and marketing.
The methodological guide includes a summary sheet, that presents results in a formal way (environmental reporting). It summarises all the key steps of the quantification process: consequence tree, quantification scope, reference scenario description.
