L-category vehicles may be type-approved only if they comply with the following environmental requirements:
| Test type | Description | Requirements: limit values | Subclassification criteria in addition to Article 2 and Annex I | Requirements: test procedures |
|---|---|---|---|---|
| I | Tailpipe emissions after cold start | Annex VI (A) | UNECE global technical regulation No 2, Chapter 6.3. L-category vehicles equipped with a combustion engine having a displacement < 50 cm3 and travelling with vmax < 50 km/h shall be attributed to class I vehicles. | |
| II |
| Directive 2009/40/EC (6) | ||
| III | Emissions of crankcase gases | Zero emission, closed crankcase. Crankcase emissions shall not be discharged directly into the ambient atmosphere from any vehicle throughout its useful life. | ||
| IV | Evaporative emissions | Annex VI (C) | ||
| V | Durability of pollution control devices | Annexes VI and VII | ||
| VI | A test-type VI has not been attributed | Not applicable | Not applicable | |
| VII | CO2 emissions, fuel and/or electric energy consumption and electric range | Measurement and reporting, no limit value for type-approval purposes | UNECE global technical regulation No 2, Chapter 6.3. L-category vehicles equipped with a combustion engine having a displacement < 50 cm3 and travelling with vmax < 50 km/h shall be attributed to class I vehicles. | |
| VIII | OBD environmental tests | Annex VI (B) | UNECE global technical regulation No 2, Chapter 6.3. L-category vehicles equipped with a combustion engine having a displacement < 50 cm3 and travelling with vmax < 50 km/h shall be attributed to class I vehicles. | |
| IX | Sound level | Annex VI (D) | When UNECE regulations Nos 9, 41, 63 or 92 replace the EU proprietary requirements set out in the delegated act on environmental and propulsion performance requirements, the (sub-)classification criteria laid down in those UNECE regulations (Annex 6) shall be selected with reference to test type IX sound level tests. |
