Crown’s Clean Air range offers both research-backed, customisable air filters that actively remove NOx from the air and a range of EV Charging systems the provide a cost-effective vehicle charging solution for councils – facilitating greater uptake of electric vehicles that will eventually drive more-polluting vehicles off the road.

At Crown International, we are proud of our history at the vanguard of road and rail-side safety innovation. But public health and safety doesn’t stop with speed cameras and improvements to equipment maintenance procedures.

Air pollution is one of the biggest challenges facing people around the world and, at Crown, we believe developing solutions – not simply taxing people – is the way to drive change.

The Crown ‘Clean Air’ range includes Electric Vehicle (EV) Charging points and the Crown Clean Air NOx Filter that has been proven to actively remove Nitrous Oxides (NOx)* from the air we breathe.

*NOx – generic term for nitrogen oxides. Mainly NO2 (Nitrogen Dioxide) and NO (Nitric Oxide)

At a NOx choking point

Fossil-fuel-powered vehicles emit a range of particulates that reduce air quality – not just CO2 – and are likely to be on our roads for years to come.

Air pollution has long been linked with a range of health risks, including breathing difficulties such as asthma, emphysema and chronic bronchitis, but new research points to a far wider range of health impacts, with cardiovascular disease, lung cancer and even dementia now being attributed, in part, to the quality of air we breathe.

One of the key pollutants is Nitrous Oxide (NOx), which originates primarily from motor vehicles and tends to gather at a height that exposes the youngest members of society to greatest risk.

Concentrations of NOx in the air remain stubbornly high, despite growing public awareness and a  range of punitive financial measures across the country that are designed to drive polluting vehicles out of urban centres.

Local councils have a legal responsibility to provide clean air but many urban areas regularly have air pollution levels that exceed WHO guidelines.

With clear links between air quality and human health, it’s entirely conceivable we could see claims brought by both workers and residents over the next few decades, potentially on a scale only previously seen with asbestos-related illness.

In short, NOx is choking our towns and cities. Taxation isn’t working. It’s time for solutions.

Air pollution: Fast facts and figures

In EU countries, the legal limit for NOx in the air is 40 µg/m3.

According to the Air Quality Europe report 2018, 23 of the 39 countries in the European Economic Area had NOx averages above this level in 2016, including 13 areas of the UK.

The road transport sector contributes the highest proportion of NOx emissions (39%) to the air we breathe. However, population exposure to ambient NOx is considerably higher in urban areas.

NOx levels in European cities have remained unchanged over the last decade near roadways, despite increasingly stringent regulation of NOx emissions from vehicles.

99,700 years of lost life* are attributable to NOx exposure in the UK alone.

*Years of life lost (YLL) are defined as the years of potential life lost due to premature death. It is an estimate of the average number of years that a person would have lived if he or she had not died prematurely. YLL takes into account the age at which deaths occur and is greater for deaths at a younger age and lower for deaths at an older age. It gives, therefore, more nuanced information than the number of premature deaths alone.
