- How does PBL evaluate the quality of its models?
What is Integrated Assessment?
Integrated Assessment is a method commonly used by the PBL and in environmental sciences, in general. Environmental problems cut across the boundaries between academic disciplines. Integrated assessment, therefore, integrates knowledge from two or more domains into a single framework. Integrated Assessment is referred to as assessment, because it provides useful information for policy-making, rather than advancing knowledge for knowledge's sake.
Who should I contact for more information about PBL maps and graphs?
The (carto)graphic editorial board of the PBL is involved in the process of editing and producing graphs, maps, and diagrams for PBL publications. These could be scientific publications, reports for policymakers, or internet publications.
Activities of the (carto)graphic editorial board include:
- Development of (carto)graphic guidelines to better reflect the message in a map or graph.
- Harmonisation of figures and text within PBL publications.
- Storage and administration of data and figures, and providing them to PBL researchers and collaborating institutions.
- Supporting the designing and development of presentations for official use

Why does PBL use models next to measurement results in environmental assessments?
The PBL uses models to interpret measurement results and to explore possible future developments. As carrying out measurements is very expensive, mathematical methods enable us to obtain reliable results with as few actual measurements as possible. Moreover, measuring future events is of course impossible.
How does PBL evaluate the quality of its models?
We judge the suitability of computer models for use in environmental assessments. This judging is done by comparing model results to measurement results, or results from similar models, and by expert evaluation. The uncertainties around the model results that are most relevant to policy are identified and reported.
How does PBL deal with uncertainties in environmental assessments?
Many aspects may contribute to uncertainties in the results of environmental assessments, for example, uncertainties around measurement results, model assumptions, or because of a lack of knowledge. We try to deal with these uncertainties by assessing them and communicating them to policymakers and other stakeholders. For this purpose, together with Utrecht University and with inputs from a multidisciplinary team of more than 25 uncertainty experts from all over the world, we developed the Guidance for Uncertainty Assessment and Communication. This Guidance is implemented in the working procedures of the PBL. The Guidance is available in hard copy and as interactive web application.
