Air Quality

The Council is responsible for reviewing and assessing the quality of outdoor air in Craven to determine whether local air quality meets required government standards.

Under Part IV of the Environment Act 1995 every local authority is required to regularly review and assess the air quality in its area to determine whether the Government's air quality objectives will be met. The Council is required to designate as an air quality management area (AQMA) any area which does not meet or is not likely to meet one or more of the objectives. To date (November 2012) no air quality management areas have been designated within Craven.

Craven District Council monitors Nitrogen dioxide (NO2) levels.

Nitrogen Dioxide (NO2)

NO2 is one of a number of nitrogen oxides, which are formed during high temperature combustion processes with road traffic being the main source, accounting for approximately 50% of all European emissions. Concentrations tend to be highest in urban environments with high traffic levels. Large industrial sources can also have a significant impact. NO2 is a respiratory irritant and also plays a part in the production of another atmospheric pollutant, Ozone

How are NO2 levels monitored?

The NO2 diffusion tube method is used to monitor levels right across the district. Tubes are left in locations for four week periods, sent for analysis with the results assessed annually. NO2 has been continuously monitored across the district since 1999 and the latest Updating and Screening Assessments and Annual Progress Reports covering  the last 3 years are available for downloading below.
