Renault ‘lollipop’ measures air pollution to reduce idling

Renault has customised the traditional lollipop to monitor air quality levels during the school run in order to mark Clean Air Day (October 8th).

Renault commissioned the custom lollipop as part of its ‘Be Mindful, Don’t Idle’ campaign to raise awareness of the impact of parents and guardians leaving their engines running during the school run.

According to its nationwide research, 27% admit to idling regularly.

One side of the Renault lollipop displays the exact concentration of fine particulates – known as PM2.5 – in the atmosphere thanks to in-built air sensor technology. It displays the pollution level in real-time to road users.

The reverse features simple iconography that shows whether it is ‘Good’, ‘Okay’ or ‘Poor’ allowing both parents and children to see the quality of the air they are breathing as they enter the school gates. The bands are based on the boundaries published by the Department for Environment Food & Rural Affairs (DEFRA), running through a range of PM2.5 levels.

The lollipop features a highly accurate sensor located in the circular section at the top behind the recognisable ‘Stop’ sign. The black bars have been modified on each side to display the PM2.5 level and associated rating to drivers and pedestrians.

The World Health Organisation recommends that the air we breathe should not exceed 10 μg/m3 of fine particulate matter. The legal limit in the UK is double that figure.

Demonstrated outside Castle Newnham school in Bedford on a road with two schools and a college, the Renault Lollipop recorded air pollution figures of between 2.5 μg/m3 and 14.7 μg/m3 from 7:00 to 7:45am which is deemed as low by DEFRA.

As the morning commute began to get busier, at 8:00am, this figure quickly went up to 25.7 μg/m3 with slightly heavier traffic – exceeding the legal limit in the UK. By the time of the afternoon school run – noticeably busier than the morning one – levels continued to exceed this figure.

Renault found idling is more common in urban areas – with 50.1% admitting to doing it – compared to 12% in rural locations. More than 28% of people said they leave their engines running for 6-10 minutes.

According to research by the British Lung Foundation and Asthma UK, in excess of 8,500 schools, nurseries and colleges in England, Scotland and Wales are located in areas with dangerously high levels of pollution.
