Interpretation of Euro 7 Emission Standards and Prospects for China 7 Emission Standards
The European Union officially released the Euro 7 emission standards on 8 May 2024.The standards merge and simplify the previous Euro 6/VI emission standards for light-duty and heavy-duty vehicles,tightening pollutant emission limits based on the princi-ples of fuel and technology neutrality.The new standards introduce controls on nitrous oxide(N2O)emissions for heavy-duty vehicles and enhance the durability requirements for vehicle emissions,ensuring low emission levels throughout the vehicle's lifecycle.With re-gard to electric vehicles,the Euro 7 standards set battery reliability requirements to improve the performance of power batteries in actual use.Furthermore,the Euro 7 standards impose more rigorous controls on real-world driving emissions,for the first time addressing non-exhaust emissions(brake and tyre wear particles).With regard to vehicle emission management,the Euro 7 standards introduce several new requirements,including Environmental Vehicle Passports(EVP),On-Board Monitoring(OBM)systems,and On-Board Fuel and Energy Consumption Monitoring(OBFCM),which leverage digital monitoring and management to enhance vehicle environ-mental performance.Finally,this paper examines the conceptualisation and specifications of the China 7 emission standards with regard to pollutant limits,non-exhaust emissions,greenhouse gas control,and remote monitoring.It serves as a reference for the development of the next phase of emission regulations in China.
