How Can the Automotive Industry Reduce Nitrogen Oxide Emissions?

[DelLillian]

The automotive industry can reduce nitrogen oxide emissions through the following measures: 1. Accelerate the phase-out of yellow-label vehicles and old vehicles: Yellow-label and old vehicles generally fail to meet emission standards. 2. Strengthen environmental inspections for new heavy-duty vehicle registrations: Heavy-duty vehicles have prominent issues with non-compliance to environmental standards and are a key focus for pollution control. 3. Require heavy-duty vehicle and engine manufacturers to immediately conduct self-inspections for compliance issues. 4. Comprehensively enhance environmental supervision of in-use vehicles: Currently, the registration process for new vehicles lacks strict oversight, allowing many National I and II vehicles to enter the market disguised as National IV or V vehicles. 5. Strengthen fuel quality supervision: Fuel quality is a crucial factor in ensuring compliance with nitrogen oxide emission standards for motor vehicles. 6. Expedite the improvement of relevant emission standards: Establish and release real-world driving emission limits and testing methods applicable to heavy-duty vehicles.
