Towards a proportionality assessment of risk reduction measures aimed at restricting the use of persistent and bioaccumulative substances

International chemicals legislation aims at adequately controlling persistent organic pollutants (POPs) and substances of very high concern (SVHCs), such as persistent, bioaccumulative and toxic (PBT) and very persistent and very bioaccumative (vPvB) substances, with a view to progressively substitute these substances with suitable less hazardous alternatives. Using cost-effectiveness analysis to assess the (dis)proportionality of measures to control such substances (collectively called PBT in this paper) requires benchmarks. The present study provides building blocks for possible benchmarks by looking at the cost-effectiveness estimates for regulatory measures that have been applied or considered for various PBT substances. These cost-effectiveness estimates vary widely, and the main factors possibly explaining this variation are discussed. The available cost estimates currently do not allow deriving a value for society’s willingness to pay to reduce PBT presence, use and emissions, as decisions referring explicitly to these estimates are scarce. Roughly speaking, the available evidence suggests that measures costing less than € 1,000 per kg PBT use or emission reduction will usually not be rejected for reasons of disproportionate costs, whereas for measures with costs above € 50,000 per kg PBT such a rejection is likely. More research is needed to strengthen the evidence base and further elaborate a systematic approach towards proportionality benchmarking.
