Aims: Screening is the first, extremely important step of health impact assessment (HIA) methodology. It contributes to the decision to conduct or not conduct a full assessment, and predefines the main fields of interest of the assessment.

Methods: Although there are examples of screening tools available on the Internet and in the scientific literature, in many cases lack of access to those tools creates a barrier to the use of HIA.
