Extending responsibility is one possible solution to the problem. The main idea from Lindhqvist is that producers are responsible for environmental impacts of goods and products. In the case of waste from household, it is generated from goods that producers no longer own, which is a step away from the basic principle that responsibility is closely related to actors’ ownership of goods and products. OECD is more specific in its definition of EPR and makes an important contribution by clearly pointing out that producer responsibility should be extended beyond the consumption stage. As such, OECD emphasizes the gap in environmental regulation that EPR can close. In this sense, EPR has a specific and unique role in regulating environmental impact beyond the consumption stage when it comes to waste from consumers or households.
Determining ownership of waste, when products no longer have a commercial value, in a complex economy with many streams of products, is difficult. Consequently, demanding responsibility for products environmental impact when they are discarded is difficult, which is discussed in the next section.
EPR as a complementary policy
The EU defines waste as a substance or object that its holder discards, intends to discard or is required to discard (European Commission, 2023a). In a complex modern economy, owners can discard or leave goods when they are no longer of use. This can cause different kinds of problems and damages to society, such as littering. As discussed in the previous section, this is related to difficulties in establishing property rights and connected responsibilities.
Traditionally, responsibility and costs for waste management have been taken over by society. In Sweden and many other countries, collection of municipal waste from households is the responsibility of the municipalities under a strict monopoly. Although taking over such responsibility often leads to well-functioning waste management, it also comes with high management costs. This is because, in principle, generating waste is costless to households in the economy. Consequently, there is a lack of incentive to reduce waste, as the costs for waste management are passed on to society.
As already noted, EPR assigns responsibility to producers. This way, some problems related to the lack of incentive to reduce waste management are addressed. Because the amount or volume of produced and introduced materials on the market is related to the amount of waste generated, the latter can be used as a “good enough”-indicator of relevant policy instruments. If implementing EPR can make producers reduce the amount of material introduced to the market by presenting higher waste management costs for producers, then it is also a useful tool within environmental policy.
An obvious challenge is that producers are made responsible for environmental problems in the consumption stage. In a well-functioning economy, policy instruments to lower waste will create incentives upstream or downstream the different stages of the economy. However, because determining property rights of waste is difficult, these policy instruments are challenging to design effectively. Complementary policy instruments that can reduce environmental damage related to waste are therefore needed. Assigning responsibility to producers, i.e., implementing EPR systems, is potentially one of these complementary instruments.
It is still worth reflecting on whether EPR meets the criteria for an effective policy instrument when the responsibility of producers is limited to the post-consumer stage. In theory, the two most common criteria for effective design of environmental policies are the polluter pay principle (PPP), and to put regulation as close as possible to the source of the environmental problem. The polluter pays principle ensures that the costs of pollution and environmental degradation are paid by those responsible for causing them. When polluters are required to bear the costs of their actions, they have a financial incentive to reduce pollution which leads to more efficient resource allocation. The second criterion for an effective policy instrument is to place regulations close to the source of environmental issues, which leads to precise and tailored signals in the market to reduce environmental damage. When regulations are further away from the source, the signals are less clear, and actors may adjust to the regulations without even reducing environmental impact.
EPR, even as defined by the OECD, has problems with both these two criteria. A lot of waste is generated by consumers and although the amount of waste is related to the amount of material introduced by producers, a large part is closer related to consumer behavior rather than that of producers. If there is an overconsumption of households that generates waste, for instance, the overconsumption itself or the consecutive waste generation can hardly be reduced by putting responsibility on producers, even if the producers may increase the recycling of what is consumed. The reason is that the waste-generating behaviors, i.e., the source of the problem, are not targeted through EPR. When the responsibility lies with the producers, which is far away from consumer behaviors it may lead to adjustments by producers that have little to no effect on consumers behavior and in turn, on the amount of waste generated at the consumption stage.
As long as consumers behavior is not targeted, any responsibilities taken on by producers will at best shift the waste generating behaviors from one product to another or create a recycling market, without affecting the market of new goods with virgin inputs. Ultimately, EPR needs to be combined with other policies that target consumer behavior to achieve efficiency as an environmental policy instrument.
