Further development of the model
During the past five years the main efforts of the Danish Program for Cleaner Products
have been focused on selected industrial sectors and anchored in the respective trade
associations. Experience shows that this procedure in most cases is successful.
However, an industrial sector-oriented action often starts with the production of the
goods while the phases of use and final disposal of the products with their associated
environmental impacts not in the same degree are subject to action. On the other hand the
action has to be anchored on a suitable place and the trade associations appear to be
useful in that context.
The very ideal of a future action would be to focus on improvements during the whole
life cycle of the products and to involve trade associations and similar centrally placed
players.
The Danish Council for Cleaner Products launched in the year 2001 a project for the
development of a "Model for selection of future target areas in the Danish Program
for Cleaner Products". The model should assure that the future product-oriented
actions had focus on the most relevant products and create a concise and correct basis for
environmental assessment of all product groups. The model should also facilitate the
selection of future areas of action.
The present project has the aim of developing the first, preliminary issue of such a
model. The project is a forerunner for a more detailed study, which aim is the further
development of the model as well as to strengthen the weak spots, which by nature are
inherent in a first issue of a screening-based model.
A secondary aim of the project has been to relate the industry-oriented product actions
carried out until now with the selection of product groups, which until now have not been
submitted to an industrial sector-oriented action.
The model for selection of future target areas consists of an Access-database, which is
structured with an input of products and industrial sectors. The database is basically
structured around the Danish Statistics of Goods ("Varestatistikken"), the
Danish Statistics of Raw Materials ("Råvarestatistikken") and the Danish
Statistics of Foreign Trade ("Udenrigsstatistikken"). All three statistics are
issued by Statistics Denmark. In order to have clearness the model operates with a total
of 95 product groups (two-digit KN-code level) and 106 manufacturing industrial sectors
supplemented with 40 non-manufacturing industrial sectors within the building industry and
commercial activities (three-digit DB code level, correspondent to the international NACE
code system). Via the Statistics of goods the product groups have been related to the
manufacturing industries. Further information allows for calculation of the supply factor,
which indicates the economic importance of the product group in Denmark. Via the
Statistics of foreign trade the product groups are related to the non-manufacturing
industrial sectors (the building sector and the commercial sector are not included in the
Statistics of goods). Furthermore preliminary evaluations of the flow through the supply
chain have been carried out based on information from the Statistics of goods respectively
foreign trade. These evaluations cover the flow from extraction of raw materials, through
manufacturing to marketing of finished goods. Since no information about the flow of goods
in the supply chains is available, it has been necessary to draw a picture based on
information from a number of other statistics.
Input of products
For each of the 95 product groups an environmental assessment has been carried out and
subsequently the products have been ranked according to the three levels "High",
"Medium" and "Low". This assessment is based on the American
input/output database "eiolca" (Economic Input/Output LCA), which comprises
information about 485 product groups. The American product groups are to a certain degree
comparable to the Danish product groups. By using the American method it has been possible
to create a consistent and uniform basis for evaluation of all 95 Danish product groups.
This was not possible with the other two methods studied.
An input/output analysis does not cover the whole life cycle, but only the phases from
extraction of raw materials until and including manufacturing. Therefore the phases of use
and final disposal are not included. This in combination with the fact that the
consumption of resources is not included in the environmental assessments probably is the
most important limitation for use of the American database.
The database "eiolca" has a large number of environmental parameters of which
the following eight have been selected as representative for an assessment at screening
level:
Emission of SO2
Emission of NO2
Consumption of water
Green house effect (GWP)
Consumption of energy
Consumption of copper
Dangerous wastes (amounts produced)
Total emission of toxic substances (weighted according to degree of danger) |
Figure 1:
The eight environmental parameters used in the environmental screening.
For each of the 95 product groups an evaluation has been made with regard to the eight
parameters, which results in the scores "High", "Medium" or
"Low", and a total evaluation, which is the result of the environmental
assessment and also results in a score of "High", "Medium" or
"Low". This ranking having three levels has been chosen for the present study
while the American method has a number of inherent uncertainties. Also the chosen level of
product groups presents uncertainties. Therefore a detailed ranking having more than three
steps does not make sense.
The evaluation of a product group and the subsequent ranking of "High",
"Medium" respectively "Low" has been carried out according to the
following procedure:
- For each of the chosen environmental parameters the product groups have been classified
according to their environmental impact, starting with the most polluting ones.
Subsequently the product groups have been divided into three groups featured by the scores
"High", "Medium" respectively "Low".
- After this a total assessment of the product group has been made based on the scores for
each of the environmental parameters. The total assessment also is awarded a score of
"High", "Medium" or "Low" according to the following
principles:
| For a product group having three or more environmental parameters ranking
"High" the total assessment is judged "High". An individual parameter
ranked "High" has thus a relatively higher weight in comparison to a simple
average consideration. |
| For a product group having six or more environmental parameters ranking "Low"
the total assessment is judged "Low". With other words a product group really
needs many scores "Low" to achieve the total score of "Low". |
| In all other cases the product group has been awarded the score of "Medium". |
Subsequently as a supplement to the environmental assessment an enviro-economic
evaluation has been carried out. In this evaluation the supply factor, which is defined as
the total of import and production minus export, has been multiplied by the total
environmental assessment of each product group thus expressing the importance of the
product group with regard to environment and economy.
Input of industrial sectors
The Access database also comprises information about the product-oriented environmental
actions, which have been carried out until now. This information is divided into two
parts, the industry-oriented action comprising product panels and branch-related projects,
and the product-oriented actions comprising eco-labelling and environmental guidelines for
the public purchasers issued by the Danish EPA.
The Access database also comprises information about earlier actions carried out under
the Program for Promotion of Environmental Management and Audits launched by the Danish
EPA as well as information about categories of companies submitted to environmental
approval according to article 5 in the Act of Environmental Protection. This information
may at a later time be included in the criteria for selection of a product-oriented action
within the industrial sectors.
The development of the model for selection of future target areas and its application
in selecting potential future areas of action has been carried out in five steps as
indicated below, see Figure 2.
Step 1: |
Relation between industrial sectors and
product groups using statistical information. That means which branches are producing
which goods.
|
Step 2: |
Environmental and enviro-economic
evaluations of all product groups. This includes the award of the scores "High",
"Medium" respectively "Low" to the product groups.
|
Step 3: |
Selection of industrial sectors related
to the product groups, which are ranked "High" in both the environmental and the
enviro-economic evaluation.
|
Step 4: |
Survey of the industry-oriented
environmental actions, which have been carried out until now.
|
Step 5: |
Selection of potential future areas of
action with regard to products and a description of the product groups. |

Figure 2:
The 5 steps in development and application of the model
Application of the model for selection of future target areas on all product groups
(95) results in 45 product groups being ranked "High". Simultaneously 34 product
groups are ranked "High" according to the enviro-economic evaluation. As a total
result, 19 product groups are ranked "High" in both evaluations.
For these 19 product groups it has been studied whether or not an industry-oriented
environmental action according to the Danish Program for Cleaner Products has taken place
within the related industrial sector. In the affirmative case the product group in
question has been withdrawn from the study.
As a result of this, a number of 14 product groups represent a potential area for
future product-oriented actions in which areas no former industry-oriented action has
taken place. The selected product groups are:
| Salt, earths and stone |
| Mineral fuels |
| Inorganic chemicals |
| Organic chemicals |
| Fertilizers |
| Miscellaneous chemical products |
| Rubber and articles thereof |
| Articles of stone, cement etc. |
| Iron and steel |
| Articles of iron and steel |
| Copper and articles thereof |
| Aluminium and articles thereof |
| Miscellaneous articles of base metal |
| Railway rolling stock and signalling equipment. |
The above-mentioned potential areas of action have been selected exclusively according
to environmental and enviro-economic evaluations. Other conditions such as
"High" ranking political issues, the desirability of visible actions,
reflections about the industrial sectors interest and willingness to carry out actions,
have not been included in the present study.
Former actions have
been environmentally relevant
A comparison of the industrial sectors submitted to an environmental action according
to the Program for Cleaner Products with the present environmental assessment of product
groups shows that the former actions have been environmentally relevant. Industrial
sectors such as textiles, electronics, building and civil engineering, plastics, cleaning
products, varnishes and paint and transportation which have had or still have
environmental actions are all featured by products being ranked "High" in the
present study.
Recommended future types of action
In order to choose the relevant type of action for future environmental actions the 14
selected product groups have been studied in detail based on the information in the
Access-database. As an example, environmental information for each product group has been
examined in order to find the most important environment parameters with regard to life
cycle considerations until and including manufacturing. Furthermore the product
groups relation to one or more industrial sectors is described and the main features
of the companies covered by the industrial sector have been identified. Information about
the economic importance of the product groups for the Danish national economy, the
relations between product group and industrial sector, as well as information about
import-export is also included in the model for selection of future target areas. A large
amount of information has been included in order to carry out preliminary considerations
about the supply chain and the potential players in the field. This information is useful
for an environmental action including the most important phases in the life cycle of the
products.
Examination of the 14 selected product groups also shows important differences. Some
product groups are featured by large imports. This applies to goods such as chemicals,
rubber, iron and steel, copper and articles thereof. This finding indicates that it is
relevant to put focus on international co-operation and supplier management in
international supply chains.
Other product groups such as miscellaneous chemical products, iron and steel, articles
of iron and steel are featured by an important role of wholesalers/retailers. In this case
it is relevant to focus on actions involving both producers and wholesalers/retailers.
The types of action recommended by the present study are as follows:
- Industry-oriented action targeting manufacturing companies, which until now have not
been subject to environmental action. A prerequisite is that the action can be based in a
trade association.
- Supplementary industry-oriented action with relation to on-going activities.
- Supply chain projects laying emphasis on management in international supply chains.
- Supply chain projects laying emphasis on manufacturing, use and final disposal of the
products in which producers, wholesalers and retailers are involved or in which the users
have influence on the earlier steps in the supply chain.
- Individual projects laying emphasis on utilization and spreading of existing knowledge
including the use in public tenders.
- Inclusion in other product groups such as product groups comprising primary raw
materials and sub-products.
For each of the 14 selected product groups it has been examined which of the
above-mentioned types of action present the most promising potential. Different types of
action may be relevant to one product group.
Further development of the model
The model developed in the present project is based on screening. That means a number
of delimitations and choices have been included during the process of development. By
nature this has influence on the decisive power of the model.
The strength of the model for selection of future target areas is that it gives a
uniform and consistent environmental base for selection of relevant product groups for
future actions. The disadvantage of the model for selection of future target areas is
primarily related to the information of American origin and the selected level of details
concerning product groups and sub-trades.
Due to the fact that the American database is based on input/output analysis the phases
of use and final disposal of the products are not included in the life cycle
considerations. This should be kept in mind and emphasized in a possible further
development of the model. Furthermore information about the consumption of resources and
other environmental aspects such as waste and chemicals should be included in the model
since these aspects are not respectively to a limited extent included in the American data
base.
In order to handle the amount of information related to product groups and industrial
sectors on a screening level a superior level comprising 95 product groups, 106 producing
as well as 40 non-producing industrial sectors has been chosen. This choice implies that
some information has been put together and therefore may cover a broad spectrum of
products and industrial sectors. In a possible further development of the model for
selection of future target areas the degree of details should be increased where practical
possible. But it cannot be taken for granted to have access to more detailed information
since the existing information already at the present level is limited due to
confidentiality.
