Table 7 Changes in emissions standards for light vehicles ( ≤1,305 kg reference mass, category N1 Class I)

Standard	Introduced in Europe	Mandated in Australia for all new light vehicles	Emission limits (g/km) for petrol (diesel) engines
Standard	Introduced in Europe	Mandated in Australia for all new light vehicles	VOCs	NO_x	Particulate matter
Euro 5	2011	1 November 2016	0.10 (0.23)	0.06 (0.18)	0.0045 (0.0045)
Euro 6 and 6d	2021	To be determined	0.10 (0.17)	0.06 (0.08)	0.0045 (0.0045)

g/km =gram per kilometre; kg = kilogram; VOC = volatile organic compound

Table 8 AQI used in this and previous state of the environment reports

Category	AQI range	Colour	Description	Health advice (if any) for the general population^a
Very good	0–33	Blue	Air quality is considered very good, and air pollution poses little or no risk	None
Good	34–66	Green	Air quality is considered good, and air pollution poses little or no risk	None
Fair	67–99	Yellow	Air quality is acceptable. However, there may be a health concern for sensitive people	None
Poor	100–149	Orange	Air quality is unhealthy for sensitive groups. The general population is not likely to be affected in this range	Reduce outdoor physical activity if you develop symptoms such as cough or shortness of breath
Very poor	≥150	Red	Air quality is unhealthy, and everyone may begin to experience health effects. Sensitive people may experience more serious health effects	Avoid outdoor physical activity if you develop symptoms such as cough or shortness of breath. When indoors, close windows and doors until outdoor air quality is better
Extremely poor^b	≥200	Maroon	Air quality is very unhealthy, and everyone may begin to experience health effects. Sensitive people may experience more serious health effects	Stay indoors as much as possible with windows and doors closed until outdoor air quality is better. If you feel that the air in your home is uncomfortable, consider going to a place with cleaner air (such as an air-conditioned building like a library or shopping centre) if it is safe to do so

AQI = Air Quality Index

Health advice from NSW (DPIE 2021b). Health advice for sensitive groups is likely to apply at earlier air quality categories.
An additional ‘extremely poor’ maroon category was added in the summer 2019–20 bushfire case study to account for very high ambient fine particulate matter measurements. This category is likely to be retained by the jurisdictions. If air quality is extremely poor, residents are advised to find a room with clean air, such as a large public building with air-conditioning.
