North London’s Air

For a video talk explanation of London’s shocking Air Quality problems click here for Clean Air in London‘s One Atmosphere presentation (34mins). For daily text pollution alerts from AirText click here.

Air in North London is monitored with Automatic monitors, managed by the Environmental Research Group of King’s College London and Non-Automatic monitors, often installed by concerned citizens These reveal how badly EU pollution limits are being exceeded at particular spots. But to get an idea of pollution during typical trips for individuals, an experiment was carried out by a BBC journalist in March 2016  ‘How much diesel pollution am I breathing in?’ using a personal exposure meter loaned by Kings College London.

Pollution in London Traffic

In descending order of micrograms per cubic metre the readings were:

  • London Underground – 77.8*
  • Diesel Taxi with the window open – 19.9
  • St Pancras station concourse – 13.2.
  • Diesel air conditioned train – 8.5.
  • Cycling to and from the office in central London – 6.5
  • cycling to and from the train station in Bedford – 3.7
  • electric train – 2.4.
  • driving around Bedford – 2.1
  • walking around Bedford – 1.7
  • home – 1.4.
  • work office – 0.8

*  “below ground most of it is oxidised iron coming from the tracks. It’s well known that the Tube is a dusty environment, but what is not well known is how toxic the specific kind of particles that we breathe while travelling underground are.”

The experiment may not have been scientifically thorough, but it gave a good indication of the relative pollution levels that affect you, and your loved ones – in different places, on different days and in different ways to get about. Readings at fixed points can only give glimpses into the problem and ideally monitoring would be per person per route.

London’s Schools

How polluted is my road has a page for How Polluted is my School?. This has a map plotting schools within 150m of roads with over 10,000 vehicles a day. It points out “that children exposed to higher levels of traffic-related air pollution at school and home may be at increased risk of developing asthma.”

London’s Polluters and the Limited Power of Boroughs

London Boroughs have limited ability to effectively remove the causes of the pollution, as explained in the Jan 2016 draft of the London Local Air Quality Management Policy Guidance 2016 (LLAQM.PG (16))  states at: ”1.01 Local authorities cannot solve the problem of air pollution alone, there are many actions that are the responsibility of regional, central and European governments. However, local authorities have a central role to play in achieving improvements in air quality. They have responsibility for a number of key levers such as parking, Planning, and local roads, and they also have a wealth of knowledge about the communities they serve.”

Camden has summarised the causes of PM10 and NO2 pollution, at a London level and at a Camden level, from  raw data from Clean Air for London in its draft Camden Clean Air Action Plan 2016-18 (for public consultation February 2016). The data shows that harmful emissions arise indoors as well as outdoors.

In descending order of damage the percentages of PM10 and NO2 of the total across London from these summaries are:

Public Realm Polluters

Cars: 35.64% of PM10 and 17.64% of NO2
s: 7.92% of PM10 and 11.34% of NO2
Buses and Coaches
: 3.96% of PM10 and 10.08% of NO2
: 9.24% of PM10 and 5.67% of NO2
Ground Based Aviation: 2.64% of PM10 and 7.56% of NO2
: 3.3% of PM10 and 7.56% of NO2
Taxis: 2.64% of PM10 and 1.89% of NO2
: .66% of PM10 and .63% of NO2
: .63% of NO2

Other Polluters

Non Road Mobile Machinery Construction (NRMM): 15% of PM10 and 12% of NO2
Domestic Gas Use
: 7% of NO2
Emissions from Buildings
(Part B): 5% of PM10
Reducing Emissions from new developments
(Part A): 6% of NO2
14% of PM10 and 3% of NO2

Based on these London wide figures, priority should be given to reducing the pollution from cars, HGVs and LGVs. However, Boroughs that have high levels from construction or aviation, for instance, also need to tackle these.

  • Camden’s Clean Air Action Plan 2016-18 said (P5) that in Camden “264 deaths were attributed to air pollution in 2010. The latest figures suggest that in 2013, the percentage of Camden’s annual adult mortality rate caused by particulate matter (PM2.5) was 7.4%. This is higher than the England (5.3%) and Greater London (6.7%) averages.” 

    The London Air Quality Focus Areas lists concern at:

    • Marylebone Road from Edgware Road to Euston/King’s Cross Junction
    • Holborn High Street and Southampton Row Junction
    • Swiss Cottage from South Hampstead to Finchley Road Station
    • Kilburn High Road from Willesden Lane to Grevill Place
    • Camden High Street from Mornington Crescent to Chalk Farm


    Camden has 5 automatic monitoring sites at: Bloomsbury, Euston Rd, Holborn in Mid Town, Shaftesbury Ave and Swiss Cottage.

    Clean Air Action Plan

    Camden is currently consulting on Camden’s next Clean Air Action Plan 2016-18 which sets out the air quality issues and opportunities in Camden. Download the document here and the updated version here. It includes a range of actions grouped under the following themes:

    • Reducing transport emissions
    • Reducing emissions associated with new development
    • Reducing emissions from gas boilers and industrial processes
    • Air quality awareness-raising initiatives
    • Lobbying and partnership working

    There is a strong emphasis in this Plan on working with and challenging others to do more about air quality. This includes, for example, lobbying regional and central government on policies and issues that are not within Camden’s power, as well as working with the GLA, other Local Authorities, schools businesses and community groups to deliver project that promote cleaner and healthier travel and buildings.

    The document analyses the causes of PM10 and NO2 emissions and contains an Action Plan Matrix at p25-p41. Camden’s actions include:

    Road Transport

    • working with the network provider to improve the coverage and reliability of Camden’s existing electric vehicle charging network. Explore options to fund rapid charging electric vehicle infrastructure.
    • Increase the additional charges currently appended to business and resident parking permits if the vehicle being registered is a diesel.
    • exploring the use of Fixed Penalty Notices. Liaise with businesses and developers to reduce where possible idling, and directly contact businesses who regularly have drivers idling
    • develop the London Boroughs Consolidation Centre (LBCC) to further reduce the number of deliveries servicing council and business premises in Camden
    • encouraging schools to join the TfL STARS accredited travel planning programme by providing information on the benefits to schools and supporting its implementation. Camden already has distributed a Schools and Nurseries Cleaner Air Fund.
    • undertake measures to increase walking and cycling in Camden
    • Submit a full application for a Low Emission Neighbourhood (LEN) from the Mayor’s Air Quality Fund for a LEN in Somers Town from April 2017

    Trains and Train Stations

    • Work with major station and train operators to look at ways to improve indoor air quality at Camden’s main stations. Engage with train operators to work towards lower emission train engines, and to explore options for mitigating unavoidable emissions from diesel trains


    • Using MAQF2 funding from the GLA and in partnership with King’s College London, work with developers on improvements to dust caused by constructions.
    • Ensure that developers are compliant with new Non Road Mobile Machinery (NRMM policy) introduced in 2015
    • Work in partnership with HS2 and with other stakeholders (including other authorities, GLA, TfL, and various residents groups) to ensure that potential impacts of HS2 are minimised


    • Domestic, Business and Inhouse measures to promote fuel saving measures for domestic, commercial and their own premises.

    Communication and Engagement

    • Provide support and guidance where appropriate to ‘citizen science’ projects planned by businesses or resident groups.
    • Camden also intends to continue monitoring and to lobby and liaise where it could influence other bodies, such as TfL, the London Mayor and Government to use their powers to reduce pollutants.

    Part of Camden’s communication initiative is its Green Camden web site with advice such as lowest pollutions modes of transport, school air quality, electric transport etc.

    One initiative is the Camden Climate Change Alliance helping local businesses adopt low carbon (low pollution) measures.

  • According to the Haringey Air Quality Progress Report 2012, “Transport for London (TfL) identified nine NO2 Focus Areas within LB Haringey:”

    • Highgate A1 Archway Junction Alymer Road
    • Muswell Hill north of Highgate Wood
    • Muswell Hill Colney Hatch Lane junction with Alexandra Park Road
    • Muswell Hill Fortis Green Road and Muswell Hill
    • Bounds Green A109 junction with Durnsford/Brownlow Road B106
    • Wood Green High Road and Turnpike Lane
    • Haringay Green Lanes
    • Seven Sisters junction Seven Sisters Rd/High Road A10
    • Tottenham Hale Gyratory and A10 High Road

    LBH also had designated 7 air quality hotspot areas:

    • Turnpike Lane/ Hornsey Park Rd junction
    • Tottenham Lane/ Middle Lane junction
    • Archway Rd/Southwood Lane junction
    • Downhills Way/Lordship Lane junction
    • A10 Great Cambridge Rd/White Hart Lane junction
    • Lordship Lane/Bruce Grove junction
    • Tottenham High Rd/White Hart Lane junction

    And 3 more were to be added: Wood Green High Rd, St Aidan’s School and Jackson’s Lane.

    Since then Haringey Air Quality Assessment and Screening 2014 has been published.

    Current Monitoring

    Haringey currently has just two automatic monitor sites at Priory Park South and Haringey Town Hall.

    Clean Air Action Plan

    Haringey has an Air Quality Action Plan 2010-2018 with key priority measures as:

    • Reducing emissions from the council fleet
    • Increasing number of electric vehicle charging points
    • Increasing number of car club memberships
    • Travel plans (Council & Schools)
    • Implementation of reduced speed zones
    • Improved cycling infrastructure.

    Road Transport

    Haringey point out that “The dominant source of emissions of NO2 and PM10 in Haringey arises from road transport which the Council has little control over.” Within the area that they can affect, their intentions included:

    • A Fuel strategy is planned which will inform the Council’s sustainable transport and vehicle fleet procurement policies
    • investigate the possibility to exclude or reduce electric vehicles from controlled parking zone payments and other car parking charge schemes that are in operation across the borough and under council control in order to incentivise the take-up of electric vehicles.
    • support Car Clubs
    • Support walking and cycling and actively encourage children, parents and staff to walk or cycle to school.
    • increase charging point spaces for new developments through planning conditions and Section 106 agreements.
    • require new developments….car-clubs, be car-free developments etc
    • encourage the Mayor and Dft to amend the idling vehicle legislation and an increase in the fine. Investigate the potential to introduce non-idling zones at / around idling vehicle hotspots identified

    P21 The Tree Strategy outlines the council’s commitment to increasing the total number of trees under its ownership, although not specifically related to traffic pollution absorption.


    • require major developments to have an air quality assessment as part of the planning application.


    • Haringey is continuing to work with the GLA and Defra to explore further the possibility of legislating against the installation of biomass boilers in AQMA areas and employ other types of renewable energy technology.
    • replace ageing boilers with high efficiency condensing boilers and upgrading the central heating system through the provision of programmable temperature and timing controls through the ‘Homes for Haringey annual boiler replacement programme
    • strive to achieve a 40% reduction in carbon emissions from the council’s own estate and operations by 2015.

    Communication and Engagement

    • continue promotion of and raising awareness of carbon reduction measures to all who live and work in Haringey.

    According to a report at the Haringey 40:20 meeting on 14th Mar 2016, Haringey have allocated £203,000 for a “NO to NO2” programme. They aim to:

    • inform & raise awareness of air pollution for planners & road traffic engineers
    • do personal travel planning for schools & residents
    • engage businesses in air quality issues
    • offer free cycle maintenance
    • raise awareness with GPs on respiratory issues

Citizen Actions

Because the problem is complex, and the causes are often not near the effects – or are even visible – citizens can be more effective by working together and pooling resources. They can support positive action from the authorities; work on additional data gathering; investigate possible solutions and lobby people who could do more. See also the Green Alliance’s A Greener London -What the Next Mayor can do to Improve our Capital and Clean Air London’s Clean Air Manifesto for the Mayor. The Media is also putting pressure on the authorities to take action, such as Today , The Evening Standard “Revealed the 20 Blackspots for Toxic Air in Londons and The Guardian “The Truth about London’s Air Pollution“.

  1. Support Authorities’ constructive actions.

See above for Camden and Haringey Council’s activities. See Air Pollution – Local Effects from Global Causes for GLA, TfL, UK Government and EU aspects.

  1. Conduct additional data gathering.

See below for some local North London initiatives to monitor/understand and publicise the worst pollution culprits and locations. See also Mapping for Change that advises on citizen monitoring and advises on purchasing of monitoring equipment. Or I Like Clean Air that offers monitoring services. Nature in July 2016 said that it is important to Validate personal air-pollution sensors or regulators could be flooded with misleading data.

  1. Consider innovative solutions.

Just for example the following ideas include one that would identify vehicle by vehicle their level of pollution opening up options to remove the worst offenders; a possible way to absorb pollution through trees and a smart way to tailor (better) data to help people avoid polluted routes.

Smart identification of polluting vehicles

A trial by the Universities of Birmingham, Leeds and King’s College London, in Feb 2016, funded by the Department for Transport is for pollution cameras trialled in Birmingham and LondonThe US-manufactured devices shine a laser beam through exhaust fumes and use reflected light to measure levels of toxins. In America, the cameras are used to identify and reward the cleanest car drivers from their annual emissions test.” The Driver and Vehicle Standards Agency (DVSA) must introduce legislation from May 2017 with changes to emission inspection tests from May 2018 to comply with EU Directive 2014/45/EU.  This could be the point at which MOTs could use updated testing technology.

Absorbing pollutants with vegetation and trees

Air Quality News reported in 2012 on the woodland conservation charity’s ‘Urban air quality’ report in collaboration with Lancaster and Birmingham universities which examines how urban greening can be best tailored to achieve air quality goals while creating health and social benefits.

Smart advice on low pollution routes

Haringey promote the use of Walkit. Although this tool may not be based on sufficient data and the low pollution choice is only available for inner, west and north London there could be potential to create a smarter App. Perhaps there is scope to utilise Kings College London personal exposure meters as discussed above.

Research ways to reduce Construction Pollution

For instance the Mayors office calls for Londoners to send in any ideas of steps that can be taken to spot problems with construction sites. One idea is for contractors to use Hybrid machines, rather than continuous diesel machines, such as Firefly.

Research problems areas and solutions

For instance Underground Ventilation could affect PM2.5 pollution according to the EU.


4. Citizen Lobbying

What could be done – by whom – that isn’t being done? Lobbying needs to be focused on the people and bodies with powers over the most harmful effects. You can join in protests to the government, such as Stop Killing Cyclists had a Transport Pollution Die-In protest in April 2016 at the Department for Transport. It was to “condemn the UK government’s actions which over the last year have deliberately destroyed progress towards reducing the horrific death and disease toll from transport pollution.

Another powerful approach is to use the Courts. For instance Client Earth’s case against Defra for missing EU pollution targets requires expertise and funds. They are asking for crowd funding for the next step of its NO2dirtyair  action against Defra. “As the government can’t be trusted to deal with toxic air pollution, we are asking the court to supervise it and make sure it is taking action.” You can also seek recompense for loss and ill health through the courts. For instance “If you, or a member of your family, have been affected by air pollution and your health has suffered” contact Hodge, Jones and Allen of Hampstead, as they are “examining the possibility of bringing a “right to life” challenge arising from the health impacts of air pollution.” In June 2016 the first case was announced – against Lewisham and London.

  • EU. Your London MEPs are listed here. Make sure that your MEP knows your concerns about the ineffectiveness of the vehicle emission regulations and the relaxation of the levels when the Real World Driving Emissions test are introduced. Seb Dance is the London MEP, listed at the link, who is a member of the Committee on Environment, Public Health and Food Safety.
  • UK Member of Parliament. You can write to your MP here. Possible topics include Diesel scrappage, Vehicle Licence Taxes (Department of Transport). Another thrust would be around pollution near schools. The Camden Schools and Nurseries Cleaner Air Fund in 2013 came up with many ideas to improve air pollution and the Government could require new Academy owners to follow best practice.  
  • London Mayor. To contact the Mayor click here. To contact your local Assembly member click here. The Mayor is able to work with Transport for London and introduce the Ultra Low Emission Zone. He/she can also require Local Authorities to provide Electric Car charging points, priority for dropped curbs where motorists want to charge cars at their home. Clean Air London suggests that citizens formally ask specific questions such as: “Please tell me the [insert number e.g. 50] highest modelled annual mean concentrations held by [Defra] for each of nitrogen dioxide (NO2) and dangerous airborne particles (PM2.5 and PM10) in [insert local authority name or other place] for the latest available calendar year together with the description and grid reference for each location e.g. a named road link.” 

These are just a very few suggestions, but a concerted effort by Citizens to express their views could make a significant difference to action.

The Highgate Neighbourhood Forum Campaign for Cleaner Air aimed “to post diffusion tubes at 50 locations for a month and measure levels of NO₂ (nitrogen dioxide).” They will participate in the Hampstead Forum’s initiative above.

The Camden Green Party have been monitoring Air Quality in Gospel Oak, Highgate and Kentish Town. They are holding a public meeting on 5th April 2016 at 7pm at Kentish Town Community Centre, 17 Busby Place, NW5 2SP. “How bad is the air where you live, work and play?”

The Hampstead Forum  have “placed NO2 diffusion tubes at 31 locations around Hampstead and discovered that at some locations with heavy traffic, readings were approaching double the legal limit.” They are working with other local groups, such as those above, and held a public meeting in April 2016, reported by the Ham and High . Speakers were:

  • Prof. Frank Kelly’s Environmental Research Group at Kings College has led research into the health impacts of London’s air pollution
  • Simon Birkett, the founder of the Clean Air London campaign
  • Alan Andrews is a member of Client Earth, the legal charity that took the British government to court
  • Nicky Gavron, a member of the London Assembly and a campaigner for protecting schoolchildren from air pollution
  • Siân Berry, a councillor for Highgate, candidate for Mayor of London, and led the first air pollution study in Dartmouth Park

The meeting was hosted by Castle Debates and was be chaired by environmental lawyer Pamela Castle OBE.

Haringey Citizen Actions

To contact your Haringey councillor click here. Haringey Council’s Transport Forum has published Haringey Transport Forum 31-1-17 – Air Quality report. This shows that the majority of NOx from transport in Haringey is from TfL buses, followed closely by diesel vehicles. (p11). It also shows that Wood Green is one of the most polluted corridors in Haringey (p8).

Haringey Council has been funded £609K over 3 years from the DfT’s  £40m Go Ultra Low Cities scheme that awards funds for:

Haringey will update it’s Air Quality Action Plan during 2017 and undertake projects as part of the Haringey Transport Forum Neighbourhoods of Future  including electric charging for Taxis, encouraging businesses to trial and adopt electric vehicles and publicity events promoting clean transport.

The Hornsey and Wood Green Constituency Labour Party hosted ‘TACKLING OUR POLLUTED AIR – The Vital Role of the EU’ at St Mary’s School N8. It was chaired by Nicky Gavron of the London Assembly. and discussed:

  • Why the EO is essential for improving Air Quality
  • What can the new Mayor do?
  • The health impacts of Air Pollution

Speakers: Ian Mudway – Kings College London Andrea Lee – Client Earth Areeba Hamid – Greenpeace Murad Qureshi – London Assembly (Transport) Seb Dance – London MEP . It was also attended by Peray Ahmet, Haringey’s cabinet member for Environment and Catherine West MP.

The ideas will feed in to Sadiq Khan’s consultation on the Ultra Low Emission Zone

Haringey 40:20 Haringey Climate Forum meeting on air pollution and climate change had a meeting on Monday 14th March. The speakers were: Joanne McCartney, GLA member for Haringey and Enfield; Alison Bell, the council’s air quality officer; Ollie Hayes, Friends of the Earth clean air campaigner. “We now know that pollution causes thousands of premature deaths a year in London. Many of the causes of air pollution are also causes of climate change: diesel vehicles, emissions from industry and fossil-fuel fired power stations, and gas boilers. So there is double the reason for tackling them. What is being done locally? What more can we do locally, and what should we demand from the next Mayor of London?”

The Haringey Green Party reported in March 2016 on their recent monitoring exercise.“every single one of the sites we tested to breach EU limits and some at more than double the legal limit.’ See Haringey Choking on Toxic Pollutants in the Air we Breathe for more and for maps of the exercise results that included:

“Some of the worst polluted sites are close to schools, including primary schools. Near West Green Primary School we measured 60 micrograms per cubic meter, exactly 1.5 times the legal limit. “
