Life cycle inventory analysis
6 Life cycle inventory analysis
6.1 Data collection and calculation procedures
Data collection follows the guidance provided in /Error! Reference source not found./,
clause 4.3.2. The calculation procedures described in /Error! Reference source not
found./ are applied consistently throughout the study.
According to the definition of scope of the study, all relevant inputs and outputs related to
the products or product systems are identified and quantified.
More details on the models and unit processes are illustrated in chapter6.6.
6.2 Developing product level scenarios
Except for the required modules A1 to A3, which described the product stage, the calculation
for the other modules is based on assumptions, described as scenarios.
[Please describe the scenarios, if necessary for each life cycle stage separately]
A detailed description of the scenario(s) can be found in chapter 8.
(If an optional module of the life cycle is declared, the additional technical information
related to the scenario underlying this module, e. g. recycling or reuse rates, is a required
part of the information of the declared information module)
6.3 Selection of data/ background data
As a general rule, specific data derived from specific production processes or average data
derived from specific production processes shall be the first choice as a basis for calculating
a product LCA.
For life cycle modeling of the considered component, service or product, [software XY] is
used. All relevant background datasets are taken from [name of database] database. The
datasets from the [name of database] database are documented in [source of
documentation]. The applied data sets are representative for the year [indicate year]
and have a [global, regional, national coverage].
The description of the type of data and background data used must be reported (specific /
generic)
6.4 Data/ background data quality requirements
The requirements for data quality and background data correspond to the specifications of
EeBGuide.
[The Data sets are based on 1 year averaged data.
The time period over which inputs to and outputs from the system is accounted
for is 100 years from the year for which the data set is deemed representative.
18
Life cycle inventory analysis
The technological background of the collected data reflects the physical reality of
the declared product / product group.
The datasets are complete and conform to the system boundaries and the criteria
for the exclusion of inputs and outputs]
For life cycle modeling of the considered products the software [name of the software]
System for Life Cycle Engineering, developed by [company of the software], is used. All
relevant background datasets are taken from [name of the database] database and
provided by the company [name of the firm]. The last revision of the used data sets took
place less than [xxx years ago].
Generic data shall be checked for plausibility. Guidance for the selection and use of generic
data is provided in CEN/TR 1594.
The background report must contain:
-
the data sets used and their sources (e.g. name of the database, literature
source), including details of the year for which the data is representative,
the representativeness of the data sets used,
the treatment of missing data,
the data quality
6.5 Allocations
In the present study no/a [name allocation] allocation has been made. Detailed
explanations can be found in the chapters below.
(The following allocations have to be described if relevant:
- Allocations in the use of secondary materials as raw materials,
- Allocation of co-products (Distinction from other products manufactured in the
plant),
- Allocation at multi-input processes if carried out in the modeling,
- Allocation procedure of reuse, recycling and recovery.
The chosen allocation methods and the allocation factors from independent sources have to
be justified. The consistent application of the allocation rules must be documented.)
6.5.1 Co-product allocation
[No/the following] allocation rules are considered: [xxx]
6.5.2 Allocation of multi-Input processes
Different products are treated together within a process, as for example in a waste
incineration plant, biomass power plant or landfill. The allocation is based on a physical
classification of the mass flows.
Optionally, the environmental impacts associated with the inputs should be allocated
according to how they affect the following production processes.
[No/the following] multi-input allocation rules are considered: [xxx]
19
Life cycle inventory analysis
6.5.3 Allocation procedure of reuse, recycling and recovery
[No/the following] allocation procedure for reuse, recycling and recovery are considered:
[xxx]
6.5.4 Description of the allocation processes in the background report
The application of allocation rules meets the requirements of the EeBGuide.
6.6 Description of the unit processes in the background report
The modeling of the unit processes reported for the LCA are documented in a transparent
way and respecting the confidentiality of the data present in the background report, as for
example:
-
The allocation of corporate data to data sets from LCA programs
The assignment of process data to the subsections of the life cycle in the LCA
(This can be represented in a tabular manner or as flow diagrams (e.g. screenshots made
from the LCA program)
