(26)To reduce information and reporting requirements and to save costs for ADR entities and national competent authorities, reporting and information requirements should be simplified and the amount of information provided by ADR entities to the competent authorities should be reduced. For example, ADR entities should make their activity reports publicly available at least every two years, rather than every year. However, Member States should be allowed to set shorter reporting periods, for example reporting periods of one year. ADR entities should also have the possibility to communicate those activity reports to the relevant competent authorities in order to comply with other reporting obligations under Directive 2013/11/EU as long as they include all elements of information required in respect of such obligations.
