Technology has the potential to reduce pollution impact across the UK

People in one of the UK’s pollution hotspots will be able to breathe air that’s as clean as that found at Peak District National Park this summer1, thanks to a new fleet of black cabs that have been fitted with innovative air cleaners, containing unique patented nano carbon filtration technology. This technology works to remove up to 97 per cent of particulate matter (PM2.5) and up to 95 per cent of nitrogen dioxide (NO2) from the air inside the cab within ten minutes.

Ten electric cabs will hit London today, showcasing the technology in one of the most polluted cities in the UK. All cabs have been fitted with cutting-edge air filtration technology from AirLabs, the world’s leading pioneers in clean air technology, as recent statistics reveal that forty towns and cities in the UK are breaking World Health Organisation guideline limits for fine particle pollution.

People in one of the UK’s pollution hotspots will be able to breathe air that’s as clean as that found at Peak District National Park this summer, thanks to a new fleet of black cabs that have been fitted with innovative air cleaners, containing unique patented nano carbon filtration technology. This technology works to remove up to 99% of particulate matter (PM2.5) and nitrogen dioxide (NO2) from the air inside the cab within ten minutes.

Ten electric cabs will hit London today, showcasing the technology in one of the most polluted cities in the UK. All cabs have been fitted with cutting-edge air filtration technology from Rensair, the world’s leading pioneers in clean air technology, as recent statistics reveal that forty towns and cities in the UK are breaking World Health Organisation guideline limits for fine particle pollution.

Created as part of a new partnership between Rensair and Barclays, the ‘Barclays Air cabs’ will be available for hire on London’s roads for twelve weeks this summer – and for two days (3rd and 4th July) the cabs will be free of charge for journeys in zones 1 and 2, so more Londoners can get a lungful of fresh air.

The World Health Organization guideline safety limit for annual Nitrogen Dioxide (NO2) exposure is 40µg/m 3. When tested in the Barclays Air cabs, pre-filtered air peaked at 111µg/m3 NO2 inside the cab.

After minutes of using the air cleaning device, the air inside the cab dropped to as low as 5.7µg/m3 NO2 – as clean as the air in the Peak District National Park, which averages 7µg/m3 NO2.

Matthew Johnson, Chief Science Officer at Rensair, said:

“We’ve witnessed worryingly high levels of toxic pollution in cities across the UK in recent years, and the concern is only growing for those living and working in pollution hot spots – with London being one of the worst. An ever-increasing number of people are exposed to unhealthy pollution levels”.

“With the help of Barclays, we’re able to continue to grow as a business and commit ourselves to reducing people’s exposure to air pollution by developing new technologies and new solutions. Without the support of businesses such as Barclays, we wouldn’t be able to achieve the growth and scale that is needed for us to have the greatest possible impact on the quality of the air that people around the world breathe.”


Michael Albert, London cab driver said:

“My cab is essentially my office – and knowing that I could be spending my working day in dangerous levels of pollution is really concerning, not just for me but also for my passengers. When the weather gets warmer over the summer and more people visit London, pollution can become a real issue and I’m really pleased that these filters can bring a breath of fresh air to the centre of our great city.”

Juliet Rogan, National Head of High Growth & Entrepreneurs at Barclays said:

“Our job at Barclays is to back UK businesses by helping them grow, and we know that great businesses are often created by coming up with ways of solving the important problems that people really care about, such as air pollution.

“This is why we’ve launched our new fleet of Barclays Air cabs, which can provide cleaner and healthier air for both passengers and drivers alike. We’ve also made ten of the taxis free for two days in order to raise awareness of tech innovators like Rensair. We want to help many more high-growth entrepreneurs who create growth and jobs for the UK economy.”


The patented technology is being trialled in cabs because pollution levels inside a vehicle can be many times higher than outside; measurements of London traffic show nitrogen dioxide concentrations up to 20 times above the exposure threshold, and particulate matter concentrations four times above the exposure threshold – both of which can cause short and long-term health problems.

Recent stats unveiled London as one of the UK’s most congested cities, which means the 20,000 plus black cab drivers in London spend every day at work breathing in potentially harmful levels of pollution as well as their passengers.

But it’s not just London that could benefit from a fleet of Barclays Air cabs. Towns and cities across the UK are suffering from unsafe levels of nitrogen dioxide, with the highest levels recorded in:

  • Hafod-yr-ynys
  • London
  • Glasgow
  • Edinburgh
  • Stoke-on-Trent
  • Chepstow
  • Belfast
  • Bath
  • Bradford
  • Oxford

Barclays Air cabs are the first in a line of initiatives to showcase the positive impact of small businesses that are using technology to solve societal and environmental issues. Over the next five years, entrepreneurs working with Barclays aim to add 16,000 jobs to the UK.

Barclays is committed to backing the UK through supporting SMEs and entrepreneurs, who represent the future of UK jobs and growth. Barclays helps start a new business every 4 minutes, and nearly one million small and medium-sized businesses have been provided with guidance, financial support and more, including 100 Brexit workshops across the UK. The bank also recently launched a £14bn lending fund, to help UK businesses navigate the next 3 years.
