The Life Cycle Assessment is a multi-stage and multi-criteria analysis, which allows to measure the environmental impacts generated by a product or a service, and this, throughout its life cycle: from the extraction of raw materials to the end of life, passing by the stages of manufacture, use, etc.

The realization of an LCA can be particularly interesting for :

- public authorities (whether they intervene at international, national or European level)- scientists;
- industrial companies.However, any structure offering products and/or services has the possibility to carry out an LCA.

A Life Cycle Assessment is useful :

- to identify the environmental issues and impacts of a company;
- to develop eco-designed products;
- to compare the environmental impact of its products with those of its competitors;
- to consolidate its brand image and stand out from the competition.

LCA is composed of 4 steps, which are totally interdependent:

1. Define the scope of the study and the functional unit used;

2. Carry out the inventory of life cycle data;

3. Evaluate the environmental impacts;

4. Interpret the results.

Yes, the LCA result can be used in the GHG assessment in several ways, depending on the scenario.

One example is that a company can use the physical approach instead of the monetary approach if they purchase a product a certain number of times during the year of measurement.

Yes, LCA can measure the products of Suppliers that impact Clients' emissions.
