Drayson Technologies and private hire service Greentomatocars have partnered to create a mobile Internet of Things (IoT) sensor network that will help build a hyper-local map of air pollution in London.

Greentomatocars' vehicles will be installed with Drayson Technologies’ CleanSpace Tag, an air pollution smart sensor.

The information collected during day-to-day travels will be used to create a comprehensive map of air pollution in the capital.

Greentomatocars will pass the data on to its customers. The company also aims to identify vulnerable locations for air pollution exposure, such as hospitals and schools. It can issue drivers with best practice guidelines for travelling through these areas, such as switching to electric mode where possible.

Julia Thomas, managing director of Greentomatocars, said: “The primary principle of our business is to make the greatest possible contribution to improving the environment. Being ethical and environmentally responsible is at the heart of our business.

"Our partnership with Drayson Technologies embodies Greentomatocars’ values and we plan to use the pollution data collected to further enhance our environmental efficiency and to give London residents the information they need to lead healthier lives.”

The data from the vehicles will feed into the CleanSpace network, providing hyper-local air pollution information viewable through the CleanSpace Air Map, helping Londoners’ to see the air they breathe.

Greentomatocars will also access the air pollution data its vehicles collect through the CleanSpace Enterprise Dashboard.
