WP1.4 Risk characterisation will concentrate on the development of methods, tools and indicators for translating results of assessments to policy-makers. The main objectives of this work package will be:

• to review and evaluate a number of current methods and their use for risk characterisation. These include health impact assessment (HIA), disability-adjusted life years (DALY), cost-benefit analysis (CBA), impact pathway methodology (IPM), Bayesian belief networks (BBN), value-of-information (VOI) method.
• to develop a meta-framework, an environment and health planner, and evaluate its usability in this project.
• to review the WHO 'Environmental health indicators for Europe' project and incorporate relevant practices into the procedures utilised in INTARESE.
• to enhance the integration of the methods reviewed, and the methods developed in other WPs in SP1.
• to provide the new methodology for use in SP3 policy analyses, to collect feedback from SP3 and SP5 on various stages during the project, and incorporate that into an updated methodology.
