The Mayor of London, Boris Johnson, has published the world’s first report to use updated methods to paint an accurate picture of the true health and economic impacts of air pollution.

The report, produced by experts at King's College London, for the first time quantifies the health and economic effects of the air pollutant nitrogen dioxide (NO2), where all previous studies have focused on particulate matter (PM2.5).

Combined together the effects of both pollutants reveal a higher health impact than previously estimated after taking into account this further pollutant. The study also found that nearly half the health impacts are caused by air pollution outside London such as diesel fumes and industrial emissions transported from the Continent.

Based on this detailed information, the Mayor has renewed his call on the Government and the EU to urgently take further action to improve air quality in London, across the UK and Europe. The Mayor says believes that given our improved understanding of the health effects associated with NO2, as a first step, the Government must now rule out expansion of Heathrow.

The report focuses on 2010, as this is the most recent available ‘base’ year for the London Atmospheric Emission Inventory which provides our understanding of air quality in the city. Projections from 2008, 2017, 2015 and 2020 are also included based on the data from 2010.

As this data is five years old, it does not include the impact of the many measures the Mayor has implemented since 2010 including tightening Low Emission Zone standards, delivering more than 1,300 hybrid buses and introducing age limits for taxis, nor the expected benefits of the Ultra Low Emission Zone in 2020.

Key findings from the study found:

• In 2010 nearly half the health effects of long term exposure to air pollution were caused by pollution outside London, including 75 per cent of cardiovascular hospital admissions associated with PM2.5;

• In 2010 there was the equivalent of 5,900 deaths associated with NO2 long term exposure

• At the same time the deaths associated with long-term exposure to PM2.5 were updated. The equivalent number of PM2.5 deaths has decreased from 4,300 (in 2008 based on 2006 concentrations) to 3,500 (in 2010).

• The study for the first time combined the PM2.5 and NO2 figures to create a total figure of 9,500 equivalent deaths attributed to air quality in 2010, but based on King’s projections, this will have decreased significantly in 2017 and in 2015, and is expected to be accelerated by the ULEZ in 2020

* Reductions in pollutant levels between 2010 and 2020 result in nearly up to 4 million life years being saved. This excludes the expected impact of the Ultra Low Emission Zone, which will lead to significant reduction in the number of people living in areas of poor air quality (where levels of NO2 exceed legal limits) – by 72 per cent in central London and 54 per cent London wide

• There have also been average reductions in NO2 levels at roadside sites of more than 12 per cent (with weather effects removed)

• The report also includes a 2010 borough breakdown highlighting the estimated number of attributable deaths associated with pollutants in each area based on the local concentration and numbers in the local population

The Mayor of London, Boris Johnson said: “This is a snapshot of the true impact of air pollutants on our health. My greatest priority remains to protect the well-being and environment of Londoners, and this scientific evidence will ensure we have all the information needed to continue delivering comprehensive measures that bring real change.

“I’ve been criticised for cleaning up taxis, upgrading bus fleets and my plans for the world’s first Ultra-Low Emission Zone in 2020, but this study shows imperatively why these bold measures are required. I need the help and strong support of the Government and the EU to effectively win London’s pollution battle and target the enormous amount of toxic air transported into our great capital internationally.”

Dr Heather Walton from the Environmental Research Group at King’s College, London, author of the report said: “The health evidence on the health effects of nitrogen dioxide has strengthened in recent years, including evidence linking long-term exposure to nitrogen dioxide with mortality. It is now thought that there is an additional effect beyond that previously quantified for the effects of long-term exposure to PM2.5.

“This report quantifies the possible maximum size of this additional effect in London in 2010, expressed as loss of life years and equivalent deaths, acknowledging uncertainties such as the contribution from traffic pollutants other than NO2. It is important that these types of calculations are funded, published and debated to ensure the health benefits of policies to reduce emissions of air pollutants such as nitrogen dioxide are fully recognised and used to design the best policies for the future.”

Alongside the King’s study, the Mayor has also published an update on the capital’s Air Quality Strategy detailing the progress made on delivering hard hitting measures to tackle air pollution including securing £65 million in funding to help taxi drivers to reduce emissions and support the roll out of 9,000 zero emission capable taxis by 2020, and signing off the Ultra Low Emission Zone following extensive public and stakeholder consultation.

Taken together these measures will ensure that 80 per cent of central London meets EU legal limits for NO2 by 2020.

To support further local action to tackle air pollution the Mayor announced the start of a consultation today on improved measures for borough to tackle air pollution hot spots and local emissions (through the statutory Local Air Quality Management process). This new approach, supported with £20 million in funding through the Mayor’s Air Quality Fund, will help focus action to protect public health and reduce emissions.

Alan Andrews, Clean Air Lawyer at ClientEarth, said: “This new research piles more pressure on the Government to come up with a clear and credible plan to cut pollution from diesel vehicles.

"Following our Supreme Court victory earlier this year, they must produce plans to bring deadly nitrogen dioxide pollution within legal levels as soon as possible. Current plans won’t achieve legal limits in London until after 2030 – condemning thousands more Londoners to an early death for every year of delay.

“As shocking as they are, these deaths are really only the tip of the iceberg. For every person who dies early from air pollution, many more are made seriously ill, have to visit hospital or take time off work.

"Nitrogen dioxide is produced mainly by diesel vehicles. We need to get the worst polluting of these out of our towns and cities, away from our schools and hospitals. That requires action from the government on a national scale.

“Air quality overall is a cross-border problem which needs a cross-border solution. Today, British MEPs are voting in the European Parliament on new rules that will set emissions ceilings for air pollutants, including PM2.5, across the EU. They should seize the opportunity to set targets that will improve the lives and health of millions.”

Friends of the Earth’s London Campaigner Jenny Bates said: “It’s a scandal that thousands of people die early every year because of London’s filthy air.

“It’s time to stop tinkering around the edges. A bold and urgent action plan is desperately needed to tackle London’s illegal air quality.

“A transport revolution is required to clean up the capital’s vehicles, cut traffic levels and improve public transport, cycling and walking.

“Building more roads and airport capacity would only make matters worse.”

Keith Taylor, Green MEP for South East England, said: "On the same day a new study has shown that 9500 people die each year in London from air pollution, the European Parliament took an important step towards cleaner air by voting to adopt more ambitious targets for all pollutants except for methane, which stays the same.

"With the UK facing fines for its failure to improve air quality, this truly awful death rate throws a focus on the dire performance of our government.

"It is right that Europe is pushing ahead with more ambitious standards and our next challenge will be getting plenary agreement for them."

Labour’s London Assembly Environment Spokesperson Murad Qureshi AM said: “This research demonstrates that air pollution is one of the most serious public health emergencies facing London. Despite almost 10,000 Londoners dying every year, the Mayor has dithered and delayed when it comes to tackling our toxic air.

“It’s time for the Mayor to get serious about air quality, that means expanding the proposed ultra-low emissions zone and allowing London boroughs to opt in should they wish. It should be an indisputable right to breathe clean air, not an option extra as the Mayor is currently treating it.”
