(8)As regards the content of reports on its application, Directive (EU) 2022/1999 requires Member States to include, if possible, the determined or estimated volume of dangerous goods transported by road, in tonnes transported or in tonnes/kilometres. Due to the optional nature of that requirement, relevant data are not collected or are not reported consistently by the Member States. Meanwhile, Eurostat provides clear and consistent data regarding the carriage of dangerous goods, which the Commission relies on to draw up the triennial report to the European Parliament and to the Council. As the Commission already has access to those data, it is appropriate to remove the obligation to report the total volume of dangerous goods carried by road in the Member State in order to reduce the administrative burden.
