| Summary | Proposal to restrict the application of CO2 specific emission limits only to NMHC and CO emissions (back-to-back comparison of NOx and PM to apply under the regulation in any case). The proposal also aligns the text where applicable with the intent of paragraph 2.3.15.: “R49 original emission limits” means the emission limits as defined in Regulation No. 49 to which the original engine system was approved." | ||||||||
