5.9 Trends in NOx and SOx emissions

Project Name: URBAN GreenUP

Pillar of Sustainable DevelopmentSocietal challenge
Planet5 - Air Quality
Description

Measure air concentrations of NOx and SOx in µg/m3 at identified sampling points close to planned nature-based interventions and highway improvement schemes both pre and post-intervention. Compare these data for differences, and also compare these data to historical city wide data to identify trends.

The predominant source of NOx in Europe is road transport and it is thought that half of emissions in Europe originate from this source; certainly the highest concentrations of NO2 are generally found close to busy roads in urban areas. The main source of SO2 is fossil fuel combustion. SOx emissions in the UK have decreased substantially since 1992, due to reductions in the use of coal, gas and oil, and also to reductions in the sulphur content of fuel oils and diesel fuel used for road vehicles (DERV). The decrease in emissions over time is the continuation of an on-going trend partly due to the decline of the UK’s heavy industry.

Scale as linked to D2.2 framework
  • Neighborhood 
  • Street
Data source [ link to data framework]
  • air quality monitoring stations
    • Diffusion tubes designed to measure dissolved gaseous emissions of NOx and SOx
Data needs
  • Concentrations of NOx and SOx (µg/m3)
Expected Outputs
  • Trends of NOx and SOx (µg/m3) over time at different sampling locations
Calculation methods
  • Both the NBS intervention site and the control study site should be sampled on the same occasion. Each fixed sampling location at a study site should be sampled every month for one year pre-intervention, and for a period of at least two years following NBS implementation.
