An upcoming review of the heavy-duty CO2 emissions standards in the European Union will consider several adjustments to the regulation, including the possibility of extending the CO2 emissions reduction targets to other vehicle segments, as well as setting specific targets for trailers.

The European Commission is currently developing the requirements for the upcoming Euro VII standards. This paper assesses the total manufacturing costs of the emissions control systems—including both engine and aftertreatment technologies—that will likely be required to meet these limits.

China’s fuel consumption standards for heavy-duty vehicles (HDVs) have progressed since Stage 1 was first introduced in 2012, and Stage 4 standards are currently in development.

The monitoring of on-board fuel consumption metering (OBFCM) data is aimed at preventing a growing gap between the certified and real-world CO2 emissions from trucks. This can only be achieved, however, if regulation mandates a certain accuracy for the OBFCM methods in real-world operation.

The European Union CO2 emission performance standards for heavy-duty vehicles mandate fleet-wide average emission reductions of 15% in 2025 and 30% in 2030 for new vehicles compared to the values reported by manufacturers in the baselining period, which ran from July 1, 2019 to June 30, 2020.
