LCA Study

STEP 2/5: PERFORM LCA STUDY

An EPD summarises environmental performance from a life cycle perspective, so a Life Cycle Assessment (LCA) report must be prepared.  Collecting production and other data for the LCA report is a core activity in the process of creating an EPD.

The LCA report must:

• comply with internationally accepted principles for life cycle assessment, LCA, according to the ISO standards 14040 and 14044; and
• follow the general purpose of EPDs, the collection of data, methods and assumptions used as advocated in the ISO standard 14025 and described in the General Programme Instructions; and
• be in line with the PCR for the product category of interest.

Companies may perform the LCA themselves if they have the in-house expertise. An EPD/LCA consultant can be employed to perform this step.

Where can I find an EPD/LCA consultant?

We suggest engaging an experienced EPD/LCA professional. Both the Australian Life Cycle Assessment Society (ALCAS) and the Life Cycle Association of New Zealand (LCANZ) have the contact details of all Certified LCA Practitioners on their websites here (ALCAS) and here (LCANZ).

Alternatively, look for an EPD for a similar product in our EPD library here or the International EPD System EPD library here and see which consultant has helped prepare the EPD.

Sourcing LCA background data

An excellent source of regional lifecycle data is the Australian Life Cycle Inventory Database Initiative (AusLCI). This provides a national, publicly accessible database of authoritative, transparent environmental information on a wide range of Australian products and services.

In some cases, specific LCA data does not exist, which can lead to difficulties in acquiring data to cover the entire lifecycle of a product or service. EPD Australasia and the International EPD® System allow organisations to use a defined proportion of selected generic data in their LCA calculations. The use of generic data is described in the PCR.
