life cycle assessment (LCA) is the compilation and evaluation of the inputs, outputs and the potential environmental impacts of a product system throughout its life cycle.
This is raw material directly used in the production of goods. This is not the same as fuel used to power the production process as this only indirectly contributes to the production of goods.
Global Warming Potentials (GWP) are calculated as the ratio of the radiative forcing of one kilogramme of greenhouse gas emitted to the atmosphere to that from one kilogramme of carbon dioxide over a period of time (e.g. 100 years).
