and\n\n(b) in force at the commencement of this Standard.\n\n0.3.2 This Standard also repeals each instrument made under section 7 of the Motor Vehicles Standard Act 1989 that creates or amends a vehicle standard with the name ADR 79/00, if there are no other vehicle standards created by that instrument that are still in force at the commencement of this Standard.\n\n# 1 SCOPE\n\n1.1 This vehicle standard prescribes the exhaust and evaporative emissions requirements for light vehicles in order to reduce air pollution.\n\n# 2 APPLICABILITY AND IMPLEMENTATION\n\n2.1 This vehicle standard is applicable to all M1 and N1 category vehicles with a GVM less than or equal to 3.5 tonnes, in accordance with the requirements of clause 1.1 of Appendix A and as provided in clause 2.2.\n\n2.2 This standard applies:\n\n2.2.1 from 1 January 2002 in relation to new model vehicles with an engine that operates on diesel produced on or after 1 January 2002:\n\n2.2.2 from 1 January 2003 in relation to vehicles with an engine that operates on diesel produced on or after 1 January 2003, other than new model vehicles referred to in clause 2.2.1;\n\n2.2.3 from 1 January 2003 in relation to new model vehicles with an engine that operates on petrol, liquefied petroleum gas or natural gas produced on or after 1 January 2003;\n\n2.2.4 from 1 January 2004 in relation to vehicles with an engine that operates on petrol, liquefied petroleum gas or natural gas produced on or after 1 January 2004, other than new model vehicles referred to in clause 2.2.3.\n\n2.3 For the purposes of:\n\n2.3.1 Clause 2.2.1, a “new model vehicle” is a vehicle of a model first produced with a date of manufacture on or after 1 January 2002.\n\n2.3.2 Clause 2.2.3, a “new model vehicle” is a vehicle of a model first produced with a date of manufacture on or after 1 January 2003.\n\n2.4 To the extent of any inconsistency, the applicability dates specified in clause 2.2 apply in lieu of any dates specified in Appendix A.\n\n2.5 Vehicles complying with ADR 79/01 Emission Control for Light Vehicles, need not comply with this vehicle standard.\n\n# 3 DEFINITIONS\n\n3.1 For the purposes of clause 2.3, “date of manufacture” means the date the vehicle is available in Australia in a condition which will enable an identification plate to be lawfully affixed to the vehicle.\n\n# 4 REQUIREMENTS\n\n4.1 Vehicles complying with the requirements of Appendix A of this vehicle standard, as varied by Part 5 and Part 6 of this vehicle standard, will be accepted as complying with this vehicle standard.\n\n# 5 EXEMPTIONS AND ALTERNATIVE PROCEDURES\n\n5.1 Any provision related to the administrative processes for obtaining a UN ECE approval in Appendix A do not apply to this vehicle standard.\n\n5.2 The requirements of Approval A (vehicles fuelled with leaded petrol) of Appendix A of this vehicle standard do not apply to this vehicle standard.\n\n5.3 The requirements of Annex 4A of Appendix A of this vehicle standard do not apply to this vehicle standard.\n\n5.4 The reference to “Regulation No. 49 as amended by the latest series of amendments” in clause 1.1.4, Part 1 (Scope) of Appendix A, is amended to read “ADR80/00.”\n\n5.5 In paragraph 2.4 of Appendix 1 of Annex 7 to Appendix A, replace the equation with the following:\n\n![](image.002.png)\n\n# 6 ALTERNATIVE STANDARDS\n\n6.1 Subject to Part 5, the technical requirements of UN ECE Regulation 83 UNIFORM PROVISIONS CONCERNING THE APPROVAL OF VEHICLES WITH REGARD TO THE EMISSION OF POLLUTANTS ACCORDING TO ENGINE FUEL REQUIREMENTS, incorporating all amendments up to and including the 04 Series of Amendments, are deemed to be equivalent to the technical requirements of this vehicle standard.\n","sortOrder":0}],"analysis":{"flash_summary":{"complexity_score":5,"scope_assessment":{"changed":true,"description":"This instrument expressly repeals earlier ADR 79/00 instruments and restates emissions requirements while introducing specific applicability dates and exemptions (clauses 0.3.1–0.3.2;

It also declares UN ECE Regulation 83 (04 series) equivalent to its technical requirements (clause 6.1), which changes how compliance may be demonstrated and narrows or alters procedural obligations (for example by removing certain UN ECE administrative approval steps — clause 5.1). The practical scope therefore shifts from prior instruments by updating applicability timing, exempting certain approval procedures, and permitting an alternative, externally drafted technical standard as equivalent."},"complexity_factors":["Multiple staggered applicability and commencement dates for different fuels and ‘new model’ definitions (clauses 2.2, 2.3, 2.4)","Repeal mechanics that replace prior ADR 79/00 instruments but preserve some prior standards (clause 0.3.1–0.3.2)","Deeming of an external technical standard (UN ECE Regulation 83, 04 series) as equivalent, creating reliance on an incorporated external text (clause 6.1)","Cross-references to Appendix A and further variation by Parts 5 and 6, requiring users to read multiple annexes for full technical requirements (clause 4.1, Parts 5–6)","Targeted exemptions and procedural carve-outs (e.g. administrative UN ECE approval steps, leaded petrol Approval A, Annex 4A) that alter compliance pathways (clauses 5.1–5.3)","Specific technical amendment to an equation in an annex (clause 5.5) — requires technical checking of replaced formulae in Appendix A","Ministerial instrument origin and delegated rule-making context (introductory paragraph — determined under subsection 7(1) of the Motor Vehicle Standards Act 1989) which concentrates decision authority","Direct effect on private economic actors (manufacturers/importers) who shoulder testing, certification and documentation costs (clauses 2.1, 4.1, 5.1–5.5)"],"plain_english_summary":"This Standard sets exhaust and evaporative emissions limits for light vehicles (M1 and N1 ≤ 3.5 t), replaces earlier ADR 79/00 instruments, phases in compliance dates for diesel and petrol/LPG/natural gas between 2002–2004, and treats UN ECE Regulation 83 (04 series) as technically equivalent.

Specifically, it limits **exhaust emissions** (the fumes coming out of the tailpipe) and **evaporative emissions** (fuel vapours that escape from the vehicle).\n\n**Who it affects:**\n\n*   **Car manufacturers and importers** – they must ensure vehicles meet these pollution limits before selling them in Australia.\n*   **Light vehicles** – this covers passenger cars (M1 category) and light commercial vehicles like utes and vans (N1 category) weighing up to 3.5 tonnes.\n*   **Different fuel types** – the rules apply to vehicles running on diesel, petrol, liquefied petroleum gas (LPG), and natural gas.\n\n**Key timing:**\n\nThe rules were phased in gradually between 2002 and 2004 depending on the fuel type and whether it was a brand new model or an existing one:\n\n*   **Diesel vehicles:** New models from 1 January 2002; all others from 1 January 2003.\n*   **Petrol/LPG/Natural gas vehicles:** New models from 1 January 2003; all others from 1 January 2004.\n\n**How it works:**\n\nRather than writing all the technical tests from scratch, Australia adopted an international standard – **UN ECE Regulation 83** (a United Nations vehicle pollution standard) – with some local modifications. Manufacturers can also comply with a later, stricter standard (ADR 79/01) instead.\n\n**Why it matters:**\n\nThis law reduces air pollution from cars, protecting public health and the environment. It aligns Australian vehicle standards with international norms, making it easier to import compliant vehicles while ensuring cleaner air for everyone."}},"importantCases":[],"_links":{"self":"/api/acts/vehicle-standard-australian-design-rule-79-00-emission-control-for-light-vehicles-2005","history":"/api/acts/vehicle-standard-australian-design-rule-79-00-emission-control-for-light-vehicles-2005/history","analysis":"/api/acts/vehicle-standard-australian-design-rule-79-00-emission-control-for-light-vehicles-2005/analysis","conflicts":"/api/acts/vehicle-standard-australian-design-rule-79-00-emission-control-for-light-vehicles-2005/conflicts","importantCases":"/api/acts/vehicle-standard-australian-design-rule-79-00-emission-control-for-light-vehicles-2005/important-cases","documents":"/api/acts/vehicle-standard-australian-design-rule-79-00-emission-control-for-light-vehicles-2005/documents"}}
