Scope and Coverage
- Emission limits apply to all new and in-use motorcycles, tricycles, and mopeds for registration purposes.
Objectives
- Revise exhaust emission standards for new and in-use motorcycles, tricycles, and mopeds.
- Achieve substantial improvement in air quality for public health and welfare.
- Provide lead time for manufacturers to plan and design compliant vehicles.
Definitions of Key Terms
- Certificate of Conformity (COC): DENR-issued certification for meeting emission standards.
- Conformity of Production: Verification that production units meet PCAA standards.
- Emission: Measurable air contaminants or pollutants emitted into the atmosphere.
- In-use Vehicle: Motorcycle/tricycle/moped registered with Land Transportation Office (LTO).
- Moped (L1): Two-wheeled vehicle with engine ≤50cc and max speed ≤50 km/h.
- Motorcycle (L3): Two-wheeled vehicle with engine >50cc and max speed >50 km/h.
- Motorcycle (L4): Three-wheeled vehicle (including tricycles) with engine >50cc and max speed >50 km/h.
- Motor Vehicle: Any gasoline, diesel, or other non-human/animal powered conveyance for persons or goods.
- New Vehicle: Constructed entirely from new parts, never registered or sold.
- Type Approval: Official ratification of compliance with regulations.
- Vehicle Type: Category of vehicles sharing essential characteristics.
Emission Limits for New Motorcycle and Moped Type Approval
- Compliance required two years after DAO approval for new vehicle market introduction.
- Detailed emission limits set for:
- Motorcycle (L3) Level 1: CO, HC, NOx limits based on engine size (<150cc and >150cc).
- Motorcycle/Tricycle (L4): Uniform emission limits for all classes.
- Motorcycle (L3) Level 2: Stricter limits effective three years after Level 1.
- Mopeds (L1): Two levels of emission limits with specified lead times and adjusted limits for three-wheel mopeds.
- Test procedures follow European Economic Community Directive ECE 40 standards.
Issuance of Certificate of Conformity (COC)
- Application by manufacturers, assemblers, importers, or authorized representatives.
- Required documents include detailed vehicle and engine description, emission control system, fuel feed system, vehicle type approval test results, and other DENR-required particulars.
Validity of Certificate of Conformity
- Valid for six years from issuance for vehicle registration unless revoked or suspended.
- Suspension periods do not extend validity.
- Special validity rules apply for COCs issued under ECE R40.01 standards (valid until December 31, 2013).
Emission Standards for In-Use Vehicles
- Emission standards vary based on vehicle registration date:
- Registered before January 1, 2003: Higher CO, HC, and white smoke opacity limits.
- Registered between January 1, 2003, and December 31, 2011: Moderate limits.
- Registered on or after January 1, 2012: Stricter limits.
- Parameters measured include Carbon Monoxide (% by volume), Hydrocarbon (ppm), and White Smoke (% opacity).
Test Procedures for Exhaust Emission Measurement of In-Use Vehicles
- HC and CO measured at idle speed following DENR AO 2000-81 Annex C.
- White Smoke opacity measured at three-quarters maximum RPM or per manufacturer’s manual.
- Tests conducted using free acceleration method.
Separability Clause
- This Order supersedes DENR Administrative Order No. 2003-25.
- All inconsistent orders, circulars, or instructions are repealed or amended accordingly.
Effectivity
- Takes effect 15 days after publication in a newspaper of general circulation and submission to the Office of the National Administrative Registry (ONAR).
