In its transitional phase, CBAM will only apply to imports of cement, iron and steel, aluminium, fertilisers, electricity and hydrogen. EU importers of those goods will have to report on the volume of their imports and the greenhouse gas (GHG) emissions embedded during their production, but without paying any financial adjustment at this stage. While importers are asked to collect data for the fourth quarter of 2023, their first report will only have to be submitted by 31 January 2024. Furthermore, a number of flexibilities have been built into the CBAM's structure for the first year of application, such as the use of default values for the reporting of embedded emissions and the possibility to use the monitoring, reporting and verification rules of the country of production.
The transitional phase will serve as a learning period for all stakeholders (importers, producers and authorities). It will allow the European Commission to collect useful information on embedded emissions in order to refine the methodology for the definitive period, which starts in 2026. As of that date, importers will need to buy and surrender the number of “CBAM certificates” corresponding to the GHGs embedded in imported CBAM goods.
To help EU importers and non-EU installations in the practical implementation of the new rules, a new CBAM transitional registry will become available on 1 October to help importers perform and report these calculations. The Commission is also gradually making available detailed written guidance, online training materials and webinars, sector-specific factsheets and a step-by-step checklist to support businesses as the transitional mechanism begins. Reviews of the CBAM's functioning and product scope during its transitional phase will be concluded before the start of the definitive period, as well as the feasibility of extending the scope of CBAM to other goods produced in ETS sectors.
