How polluted is my road in 2020?

The Mayor's 2020 vision for air pollution

2020 vision front cover

The Mayor of London has set out his vision to make London "the greatest city on earth" in 2020, rising "to meet the challenges ahead".

One of those challenges is air pollution, which comes in many forms and has been linked to life-shortening lung and heart conditions, breast cancer and diabetes. Nitrogen dioxide (NO2) is one pollutant that can have long-term impacts on your lungs, breathing and asthma.

The Mayor's Air Quality Strategy aimed to bring the whole of Greater London within legal limits for NO2 "as soon as possible", and ideally by 2011. So will he have achieved this by 2020?

Dirty London in 2020

In 2020, using the Mayor's own projections I have estimated that:

  • 45% of the main road network will still exceed legal limits for nitrogen dioxide (NO2) pollution
  • there will still be 928 schools within 150m of main roads that exceed legal limits, increasing the risk of asthma in children
  • if you use buses, chances are you'll be waiting at one of 8,642 bus stops next to roads over legal limits

Cleaning our air

This pollution problem isn't inevitable, we can clean London's air. These are three things I'd like to see the Mayor implement.

Please note, these are my views as an individual Assembly Member and not those of the London Assembly.

Climate rush bike ride protest

Traffic reduction

Reduce polluting traffic by lowering public transport fares, and by making it nicer and safer to walk and cycle.

Fuel cell bus

Clean buses

Only buy hybrid buses and aim for zero emission (electric and hydrogen fuel cell) buses by 2020.

Low Emission Zone

Ban on dirty vehicles

Bring forward the Mayor's Ultra Low Emission Zone, only allowing clean vehicles into central London.

What do you think about air pollution in London and the possible solutions? Let me know.

Technical notes

The statistics and maps in this page are based on the 2010 edition of the London Atmospheric Emissions Inventory. This dataset is published by the GLA, and includes modelling of NO2 concentrations across the capital in 2020 based on current Mayoral and Government policies. We have reason to believe that this modelling is on the optimistic side.

My team used this data, the network of roads from OpenStreetMap, the bus stops from the DfT's NAPTAN dataset, and Quantum GIS to process it all. The methodology was as follows:

You can download two of the shapefiles we used to produce your own analysis. Let me know what you find out!
