Red Bull take action to protect their drivers as new analysis finds London in-car NO2 levels up to four times WHO limit

Red Bull take a pioneering step to install AirBubbl devices in a fleet of 21 cars to protect drivers from air pollution.

  • New analysis finds that parts of central London have average in-car nitrogen dioxide (NO2) levels almost four times the WHO limit.
  • Average in car NO levels in London found to be almost double WHO limit.
    Comprehensive analysis based on almost 150,000 data points from 28 roadside monitoring stations over a year.

Red Bull, the international energy drinks company, have installed air filtration devices into a fleet of new cars to protect their drivers from pollution, as new analysis has found that in-car NO2 levels in central London can be as much as four times the WHO limit.

The analysis, conducted by Rensair, a leading pioneer in clean air technology, found that the average concentration of NO2 that can be expected inside a car on the road in central London during working hours is 72 micrograms per cubic metre of air (µg/m3), which is 1.8 times the WHO recommended annual guideline value of 40 µg/m3.22

The highest reading came from King William Walk in Greenwich, which was almost four times the WHO limit, with an average concentration of 156 µg/m3 during working hours. Roehampton Lane in Wandsworth and Holloway Bus Garage in Islington were also highlighted in the analysis as particular areas where NO2 levels were of serious concern.

In a car cabin the level of NO2 can be up to 70% higher than for pedestrians, due to harmful gases and particles being emitted from surrounding vehicle exhausts in close proximity. These extreme pollution flows can pass straight through standard car air filters and lead to much higher concentrations in the cabin than on the pavement further away from these sources.

The analysis is based on 145,000 data points from 28 air monitoring devices across the Borough of London on weekdays between 9am and 5pm, over the 12 months from October 2018 – October 2019.

Marc Ottolini of Rensair, the company that completed the analysis, said:

"People assume that their car protects them from the air pollution in our cities, but the opposite is true, as levels of NO2 have been found to be up to 70% higher in vehicles than outside."

"This comprehensive new analysis shows that using your car in central London poses serious health risks to drivers. Any business that regularly sends its drivers into urban areas across the UK has a clear responsibility to protect the health of its staff, so it’s inspiring to see a company the size of Red Bull taking this essential step to safeguard their employees."

Long-term exposure to NO2 has been directly linked to decreased lung function in school aged children, lung cancer, low birth weight of newborns and cardiovascular mortality, as well as increasing the risk of respiratory problems.

With the UK currently in an air pollution crisis, drivers are at risk not just from NO2, but also dangerous particulate matter, which has been linked to brain cancer, respiratory and cardiovascular problems, as well as septicaemia, kidney failure, skin infections, Parkinson’s disease and urinary tract infections.

Red Bull has taken action to protect the health of its employees by installing AirBubbl devices in 21 new Skoda Scala cars. The cars will be driven by the Red Bull Musketeers – their own trade sales team – in central London and across the UK.

The AirBubbl mitigates the impact of air pollution by removing up to 99% of harmful particulate matter and dangerous gases from a vehicle. By installing the devices, Rensair have found that Red Bull will reduce average NO2 concentration levels for their drivers in central London to 12.2 µg/m3, almost a quarter of the WHO limit.News

David Oliver, procurement manager at Red Bull, said:

"We’ve become really aware and concerned about the air pollution crisis which is affecting cities across the UK. Our Red Bull Musketeers spend a lot of time driving in cities and their health and wellbeing is vitally important to us, so installing an AirBubbl in all of our new cars is a positive step to look after our staff, as any responsible business should."

"The move is part of our commitment to make our fleet greener and reduce our contribution to air pollution. With the purchase of these 21 Skoda Scalas we’re moving away from diesel to cleaner low carbon and low NO2 petrol fuel as well as looking to move to a fully electric fleet in the next 5 years across all our 200-strong UK fleet."

"We’ll also be making the rest of the business aware of the best ways to help mitigate their exposure to air pollution when travelling to, and around, any UK city on business."

Fleet drivers, including taxis, delivery vehicles and many others, make up a significant amount of London traffic and spend a substantial amount of time behind the wheel, increasing the health risks from in-car pollution.

Air pollution levels have a significant impact on the health of employees, so much so that if AirBubbls were used in a fleet of 250 cars, over the course of a year, you could expect up to 30 fewer sick days for the drivers during this time.11

Dr Ian Mudway, Senior Lecturer and air pollution specialist at King’s College London, said:

"Chronic air pollution exposures contributes to 9,000 premature deaths in London each year and our recent research has found that professional drivers have particularly high exposures for extended durations – with taxi drivers having the greatest exposures."

"It’s essential that we do more to clean the air in our cities to protect the public, as well as the health of essential workers in the transport sector from this invisible threat."

The AirBubbl is the only in-car air cleaner that contains patented filtration and air flow technology. It effectively removes harmful particulate matter and gases in minutes, delivering clean air directly to the driver and passengers.
