Abstract

Sustainability assessments provide scientific support in decision procedures towards sustainable solutions. However, in order to contribute in identifying and choosing sustainable solutions, the sustainability assessment has to fit the decision context. Two complicating factors exist. First, different stakeholders tend to have different views on what a sustainability assessment should encompass. Second, a plethora of sustainability assessment methods exist, due to the multi-dimensional characteristic of the concept. Different methods provide other representations of sustainability. Based on a literature review, we present a protocol to facilitate method selection together with stakeholders. The protocol guides the exploration of i) the decision context, ii) the different views of stakeholders and iii) the selection of pertinent assessment methods. In addition, we present an online tool for method selection. This tool identifies assessment methods that meet the specifications obtained with the protocol, and currently contains characteristics of 30 sustainability assessment methods. The utility of the protocol and the tool are tested in a case study on the recovery of resources from domestic waste water. In several iterations, a combination of methods was selected, followed by execution of the selected sustainability assessment methods. The assessment results can be used in the first phase of the decision procedure that leads to a strategic choice for sustainable resource recovery from waste water in the Netherlands.

Abstract

Ministries have each their own models to assess risks of chemicals. This report gives an overview of models used in environmental policy to asses risks on ecosystems. Nowadays, many locations deal with contamination that exceeds the risk limits. It therefore becomes crucial for environmental policy to determine real ecological risks of diffuse and chronic stress caused by single contaminants and by mixtures thereof. Effects of diffuse, chronic stressors are difficult to identify in the field. These issues triggered the development of the Stimulation Program Systems-Oriented Ecotoxicological Research (SSEO). Within the SSEO program, data are collected from diffuse and chronic contaminated fields. These data will be used in the next research phase to validate the eco(toxico)logical models used for policy formulation. The validation of models gives insight on the fact if policy measures should be (partially) intensified or relaxed for reaching the environmental policy targets.
