Analyze Eco-footprint Calculation

Explanation

The Part Eco-footprint page allows you to study the emission structure as a tree structure and also the associated emission information of a specific part. For example; you can study the accumulated total LCA emission for a specific substance built-in to the part selected in the tree structure. You can also study how a part's components contribute to the total accumulated eco-footprint for that specific part. It is possible to update your eco-footprint calculation by add/remove of substances on the specific part depending on the status of the part. For the Planned and In Progress status, substances can be added, removed or modified but for the Complete and Approved status, it is illegitimate to take any actions.

On the Structure Multilevel tab you can study the multilevel structure of the part emission. This tab contains information about the bill of material (BOM) as well as how emissions are built up through the BOM. It can be used to query for information like which components contributes with emissions of a certain substance. It is also possible to do a query based on specific criteria in order to determine which sub part and/or substances give the top part this characteristic.

Use the Material Declaration Quality tab to follow up the material declaration quality for one or a selection of parts in order to evaluate the reliability in the calculated result. This tab contains two sections; one in which you can study the total number of parts corresponding to the different material declaration qualities and one in which you can study the percentage distribution of the material declaration qualities for the sub part.

You can also study the declared mass for your eco-footprint calculation. The declared mass (%) shows the ratio (as a percentage) between the built-in substances weight and the part net weight. The built-in substances weight is equal to the sum of the accumulated weight for all substances in the structure with media code product and base UoM. In order to have a good knowledge about the substances built-in to your part the declared mass percentage should be close to 100%.

Use the Part Usage Emissions page to define and analyze amounts of emitted substances that are associated with the use phase of the part.

The Component Eco-footprint Build-Up page shows how a part's components contribute to the total accumulated emission for that part. The components are sorted by how much they contribute to the total accumulated emission. The number of components to study in the graph can be between 1 and 30.

In the LCA Stages section you have several options. A life cycle assessment (LCA , also known as life cycle analysis, eco-balance, and cradle-to-grave analysis) is the investigation and valuation of the environmental impacts of a given product or service caused or necessitated by its existence. If you enable the Cradle to Gate Emissions option, you will see the eco-footprint of the selected part during the partial life cycle from the production to the factory gate. If you enable the Use Emissions option, you will see the eco-footprint of the selected part during the partial life cycle when the product is in-use. If you enable the End of Life Emissions option, you will see the eco-footprint of the selected part at the end of the product life.

The Eco-footprints per Part History Analysis page shows the history of part emission calculations for a specific part and the selected substance code. The graph shows both the accumulated emission as well as the level emission. The period type and date range of the graph can be changed.
