EU Member States are required to ensure that up-to-date information on ambient concentrations of the different pollutants is regularly made available to the public and to other organisations. This is done by providing information on websites, in the press and also in public spaces. The information needs to be regularly updated and the connection to the different limit and target values needs to be clear. When information or alert thresholds are exceeded, Member States need to inform the public about this and the actions that are taken. See the different EU Directives for more precise details on this obligation.
