Conclusions about the products
The analysis in this chapter is based on experience gained in the environmental administrations, at companies and in the research and consultancy area over the past 5-10 years, during which the environmental properties of the products have been investigated. Chapter structure
4.2 Products covered by the product initiativeFocus on all productsAs a basic principle, the product-orientated environmental initiative should be targeted at all products manufactured and consumed in Denmark. In an open economy with extensive imports and exports of goods and services, this means that the spotlight must be on products made in Denmark, of which some are exported, as well as on products that are imported and used in Denmark. Basically, the product initiative is targeted at physical products causing major environmental impact from a life-cycle perspective. Services are also included if they entail major consumption of physical products of importance to the environment. Cleaning and transport, for instance, are services relevant to the product initiative while marriage counselling is not. Given their turnover volume and environmental impact, foods are also essential to the product initiative while works of art will only be so as an exception. Furthermore, the products include both products used by the end user, the so-called end products, and semimanufactures used in their production. A huge number of products
Short product life
Amid this multiplicity of products, initiatives must, as mentioned, be directed at those product groups causing the heaviest impact on the environment, and where such initiatives have a reasonable chance of bearing fruit. The possible success of such initiatives depends, i.a., on the market on which the products are traded, and on the stakeholders and instruments that can be activated in order to change the environmental impact of the products. 4.3 Environmental properties of products in a life-cycle perspectiveThe influence of the products on the environment depends on the environmental properties of the individual product and on the size of consumption. Environmental properties are comprised by the overall environmental impact associated with the entire life-cycle of the product (see Box 4.1). These properties can be mapped by use of a so-called life-cycle assessment (LCA).The life-cycle perspective
For many products, it will be the choice of design in particular that determines a number of the environmental properties of the product - this applies, for example, to raw materials, production processes, function mechanisms, consumption during the utilisation phase and the scope for separating or stripping the products after use. In his or her choice of consumption and the subsequent use and disposal of the product, the consumer also has a decisive influence on the overall impact during the product life-cycle. Need for extensive insight
Box 4.1
Lack of life-cycle assessment data In many cases, the source data for LCAs are generally characterised by substantial uncertainties and deficiencies. This is especially true of information about the effects that can be caused by the use and spread of chemical substances. It is equally true of information on the environmental impact of the many different processes, raw materials and materials used in the manufacture, use and disposal of products. There are also problems in operationalising an important area of action such as the preservation of biodiversity. The inventory of environmental properties of products is one of the initial elements of LCAs, which are treated in the next section. 4.4 Evaluating environmental properties of productsThe vast majority of products can cause several different environmental problems. For this reason, it is rarely possible to immediately identify the - in overall terms - most important areas of action. That applies whether one is a manufacturer, dealer, authority, or a professional or private consumer. In addition to these data, there is thus a need for usable methods of comparison as well.Methods for both professionals and others
Environmental assessment of products from cradle to grave started on a small scale, 25-30 years ago. Since the early 1990s, there has been an increasing focus on developing the methodological foundation in the field. The Society of Environmental Toxicology and Chemistry (SETAC) has been very active in this field throughout this period but still needs to operationalise its underlying methods for a number of the stages in their code of practice for LCAs. ISO standard for LCAs
The elaboration of ISO 14041 is currently being finalised and work on ISO 14043 is well under way. The drafting work on the impact assessment standard (ISO 14042) includes two difficult stages with regard to the last part of the impact assessment, on which no clarification has yet been obtained. One is the question of "normalisation" - i.e. whether, and if so how, estimated contributions to environmental effects and resource consumption should be related to overall impact and consumption. The other is the question of "weighting" - i.e. how the contributions to each of the effects and consumptions of individual resources are weighted relative to one another. The outcome will probably be that the impact assessment standard leaves the user with a number of choices by providing instructions on different possible approaches to these steps. ISO eco-labelling standard
In connection with the standards for LCAs, discussions particularly revolve around the question of whether or not to include the total life-cycle of products and the question of how to evaluate the estimated effects in relation to one another. At the same time, this is of great importance to the potential of the standards. With regard to the eco-labelling standards, there are discussions as to who should be represented and what degree of consensus should be achieved in the laying-down of criteria. EDIP - a Danish environmental assessment method
The EDIP method stipulates that environmental properties and resource consumption must be normalised so that they can be expressed in percentages of the annual impact from an average person - either in Denmark, if a local or regional effect is considered, or world-wide, if the effect is global. The following weighting of the various environmental problems is based on Danish - politically adopted - objectives for reducing various kinds of environmental impact. In the case of non-renewable resources, the weighting is based on the known supply horizon. The EDIP method forms part of an package tool which also includes guidelines on environmentally sound design, a database and a PC program that will be available in 1997. The package tool ensures that environmental considerations are included in the design of products. The tool has been developed in relation to - and has so far been applied to - five different products within the field of electromechanics. But the method and the database may also be used for environmental assessments of products in other contexts and for other purposes. Knowledge of the environmental properties of products is relevant to all stakeholders involved throughout the product life-cycle. If this knowledge is not generated and disseminated, there is no basis on which to act. This topic is examined below. Here, it will be sufficient merely to present a number of examples of cases in which evaluations of the environmental properties of products are relevant to different stakeholders and examples of the knowledge that we in Denmark have in the field today. In not nearly all cases, the use of such a relatively complicated environmental assessment method such as the EDIP method will be a feasible prospect though it will usually be possible to base the product evaluations on the same principles or on parts of the method.

Main products from an energy and resource angle On the basis of energy consumption and resource losses, an examination of industrial products in Denmark allocates top priority to products within the sectors of transport, agriculture and food, construction and textiles when the products are considered throughout their entire life cycle /4/. What now needs to be investigated is whether the priority-setting method employed can be expanded to include the content of the products of environmentally or health hazardous chemical substances.

4.5 The potential of environmental improvements of productsNo sense in specific goalsThere are enormous variations in the dimensions of the relative or absolute environmental improvement that has been achieved through the current environmentally improved products familiar to us. Nor is there any sense in trying to draw up a specific goal for environmental improvements of products on the Danish market. The products vary far too much for that, and our knowledge of both the technical and the economic conditions needed to reduce the environmental impact of the products is much too insufficient. Reductions in energy and resource consumption and in emissions of xenobiotics can be achieved by economising and using known or adapted technologies. Extra insulation on refrigerators or electronic control of the energy or water consumed by products are examples of this. Technological leaps often needed
When the consumption of environmentally or health hazardous substances is concerned, there is no immediately visible limit to the improvements that are possible. Even today, many substances may be replaced by other environmentally acceptable substances or functions. Nor is there any reason to believe that such possibilities will be exhausted for the time being. Tools cannot suggest alternatives
4.6 Environmental properties are not absolutely allProducts are used for fulfilling a function or a particular need. Any initiative geared towards a product or product group must be based on the precondition that the need to be fulfilled can be fulfilled in a way that is environmentally and socially more ideal.There will be different understandings of the function of a product or the alternative ways in which a need can be satisfied. As a rule, the manufacturer of a product will look at changes within his product field while a private consumer has far more wide-sweeping possibilities of choosing between basically different ways of fulfilling, e.g., an entertainment function. Function and quality must be preserved when improving environmental properties
This is also a logical prerequisite if products are to be able to compete on a market on which products are bought primarily to fulfil a need, and, only secondarily, other factors such as environmental and working environment properties will be examined. It is important, then, for product initiatives to contribute to the development of a practice in which all relevant stakeholders in all relevant decision-making situations simultaneously take into account:
