Article 15 1.

the number of registrations of zero-emission heavy-duty vehicles in Member States;

the progress in the deployment of public and private alternative fuels recharging and refuelling infrastructure for heavy-duty vehicles covered by this Regulation, as well as the existence of infrastructural constraints in third countries on the operation of newly EU-registered heavy-duty vehicles outside the Union;

the impact on employment, especially on micro, small and medium-sized enterprises (SMEs), the effectiveness of measures to support retraining and upskilling of the workforce, and the importance of an economically viable and socially fair transition towards zero-emission road mobility; special emphasis shall be placed on the impact on peripheral Member States and on the impact on the transport of perishable goods;

whether the continuation of the exemption set out in Article 6b for manufacturers producing few vehicles is still justified;

the impact of establishing minimum energy-efficiency thresholds for new zero-emission heavy-duty vehicles placed on the Union market;

the level of the excess CO2 emissions premium, to ensure that it exceeds the average marginal costs of the technologies needed to meet the CO2 emissions reduction targets;

the inclusion of the following heavy-duty vehicles, which do not currently fall within the scope of Regulation (EU) 2017/2400, in the CO2 emissions reduction targets:

any specific constraints in complying with Article 3d(1) due to socio-economic cost benefits in view of specific territorial morphology or meteorological circumstances, as well as recent investments in biomethane already made by public authorities;

the role of a carbon correction factor in the transition towards zero-emission mobility in the heavy-duty vehicles sector;

the role of a methodology for registering heavy-duty vehicles running exclusively on CO2 neutral fuels, in conformity with Union law and with the Union climate-neutrality objective;

whether the creation of new vehicle sub-groups for EHC lorries has led to an undue increase in engine rated power;

the possibility of developing a common Union methodology for the assessment, and the consistent data reporting, of the full lifecycle CO2 emissions of new heavy-duty vehicles that are placed on the Union market;

options to consider zero-emission heavy-duty vehicles which have been retrofitted from conventional heavy-duty vehicles previously registered, for the purposes of compliance assessment under this Regulation.
