Regional Council Airshed Studies

Councils are responsible for monitoring and managing air pollution to meet requirements set by the National Environmental Standards for Air Quality (NES).

The National Environmental Standards for Air Quality (NES) were introduced by the Ministry for the Environment (MfE) in 2005 (currently under review). They set standards for ambient (outdoor) air quality; dealing with pollutants such as sulphur dioxide, carbon monoxide, nitrogen dioxide, ozone, and airborne particles less than 10 microns in diameter (PM10).

Councils are responsible for monitoring, managing and publicly reporting air pollution. The NES allows PM10 to exceed 50 micrograms/m3 of air on no more than one occasion a year. Councils have until 2013 to manage air quality to ensure compliance with this standard.

Results can be provided based on annual average, season or on specific days of high contributions.
