Rationale and central question
Current policy on hazardous substances is not sufficient to adequately control the risks to people and the physical environment. The use and number of hazardous substances is increasing, as is the reuse of products containing such substances. New policy is needed if we are to get a grip on hazardous substances.
Over the course of several decades, government policy successfully reduced the occurrence of hazardous substances in the physical environment, but of late this development is stagnating. The number of hazardous substances is increasing, as is the number of products that contain them. As a result, these substances are accumulating in the physical environment, giving rise to new risks and incidents. Examples of such risks and incidents include PFAS, plant protection products, microplastics and pharmaceutical residues.
The advisory report centres on the question of whether safer handling of hazardous substances in the physical environment is necessary and what steps should be taken to this end.
In this advisory report, the Rli makes 10 recommendations to effectuate a better grip on the dispersion of substances within the environment, reduce the adverse effects of cumulative exposure and move towards a safe circular economy by 2050. The recommendations are partly aimed at involving social parties more actively in assessing the usefulness and necessity of chemical substances. This requires greater transparency. Knowing which substances are in which products and what risks are involved is crucial to achieve safe closed-loop systems.
Transparent information and more knowledge needed
To prevent further increase in the risks related to hazardous substances, first more knowledge is needed about the extent to which they end up in the physical environment. This applies to the various phases of production, use, reuse and waste processing. The Rli, therefore, advises the Dutch Government to compel companies to keep track of the routes travelled by these hazardous substances throughout their lifecycle, using a track & trace system. In addition, government policy capacity and knowledge must be enhanced to improve policy implementation, enforcement and supervision. This calls for additional budget being allocated to this purpose.
Limit the risks of cumulative exposure, for both people and the environment
As increasing numbers of hazardous substances are used more often and in larger quantities, this also increases the risk of simultaneous exposure to multiple substances. Previously, risks to humans and the environment mainly were caused by exposure to individual substances. Today, however, there are many more diffuse mixtures of substances, each in low concentrations, but together they may have an equally harmful effect. The Rli recommends that the effect of this simultaneous exposure is taken into account when setting national environmental standards. This may also be necessary in specific areas, for which government will need to support municipalities and provinces.
Safe product reuse and recycling calls for new European regulation
The transition towards a circular economy poses new challenges. A circular economy has closed-loop cycles, which also means that hazardous substances can accumulate within those cycles. Prior to the production and reuse of such substances, specific attention should be paid to ensuring their safe reuse. The Rli, therefore, calls on the government to promote rules and regulations, on a European level, which incorporate such reuse into the risk assessments of substances. In addition, information should be readily available on the substances contained in all products. In this context, the possibilities for introducing a material passport for the chemical composition of each product should the investigated. Such passports would offer insight into the possibilities of reuse for the producers and users of those products.
On-line debate session and publication date
On-line debate session 8 june 2020
The Dutch Council for the Environment and Infrastructure (Rli) organized an on-line debate session with live presentations, on Monday, 8 June 2020 (10:30–12:45 hrs). At this meeting, the Council presented and discussed its advisory report concerning national and EU policy on hazardous substances. With the discussion and reflection involving experts, stakeholders and NGOs, the Council contributed to the debate on a European level. Diederik Samsom, Head of Cabinet of the European Commissioner Timmermans, gave his reflection on the discussion.
Publication date 11 maart 2020
On 11 March 2020, the Rli published its advisory report, ‘A grip on hazardous substances', and presented it to Minister Van Veldhoven for the Environment and Housing.
