Citizen Science project helps City residents measure air quality

A new project has launched in the City of London giving residents the opportunity to measure local air quality, seven years after a similar study took place.

The City of London Corporation, which governs the Square Mile, is running the initiative at the Barbican and Golden Lane Estates alongside social enterprise Mapping for Change in a year-long study starting in March.

Mapping for Change (MfC) will work with the community to measure air pollution at a number of locations for a year.

MfC will also be filming for a documentary on the work running a social media campaign to highlight the benefits of community engagement and action, and will write an academic paper on the results.

The project aims to show the improvements in air quality that have occurred since the original Citizen Science programme, which took place in 2014, demonstrating the value of community input in tackling local environmental issues.

Several recommendations that were made by residents during the initial project have been implemented leading to improved air quality in the area.

This includes a three year Low Emission Neighbourhood programme which saw the implementation of electric vehicle charging points, green infrastructure, cargo bikes and a zero emission street pilot.

The City of London’s central location, along with a dense road network and high buildings, means that it faces a particular challenge when it comes to air quality.

Around half of London’s air pollution comes from road transport. Nearly half of car trips made by Londoners before the coronavirus lockdown could be cycled in around ten minutes.*

Chairman of the City of London Corporation’s Environmental Services Committee, Keith Bottomley, said:“We are very excited to be running this community citizen science project.

“We’re working closely with our local community, raising awareness around air pollution and how to reduce exposure, and we’ve rolled out several bold and practical measures which have improved local air quality.

“But there is still work to do, and this project is another important step forward towards cleaner air in the City.”

Louise Francis, Managing Director at Mapping for Change, said:

“We are delighted to be involved once again in such an exciting project to engage residents around the Barbican and Golden Lane Estates in air quality monitoring.

“Air pollution is a primary concern for many of us living in busy cities and the first step to bringing about change is raising awareness and understanding of the issue.

“We believe Citizen Science can not only achieve this but also allow us to look at the problem through a new lens in order to find solutions and monitor success.”

The Citizen Science project is just one part of the City Corporation’s drive to improve air quality.

The City Corporation has recently launched an ambitious Climate Action Strategy, which will make the Square Mile net zero carbon-emission by 2040, 10 years earlier than government goals.

As part of the plans, the governing body has committed to achieve net zero carbon emissions from its own operations by 2027 and 2040 across its investments and supply chain.

Its Planning and Transportation Committee has backed proposals to turn parts of the Square Mile into zero emissions zones and reduce motor traffic as part of its radical Transport Strategy.

And it has already banned the purchase of diesel vehicles from its own vehicle fleet, where there is a clean market alternative.

The City Corporation is leading a London-wide crackdown on drivers who leave their engines idling and recently toughened its stance by agreeing to introduce Penalty Charge Notices and increase the fine for non-compliant drivers.

Its CityAir app provides over 35,000 Londoners with low pollution travel routes across the capital, with advice and alerts when air pollution is high.

And its emissions-based charges for on-street parking in the Square Mile targets high polluting transport with higher charges, while rewarding drivers of low emission vehicles with lower tariffs.

About the City of London Corporation

The City of London Corporation is the governing body of the Square Mile dedicated to a vibrant and thriving City, supporting a diverse and sustainable London within a globally-successful UK.

Key statistics about travel and transport in the City of London:

  • 84% of commuter travel to the City is by public transport, 5% by walking and 4% by cycling. Fewer than 5% of City workers drive to work.
  • 45% of motor vehicles in the Square Mile are cars (including private hire vehicles), 21% are taxis and 22% vans and goods vehicles.
  • The number of cyclists on City streets has significantly risen across the last decade (up 292% since 1999), while the number of vehicles using the Square Mile’s streets has halved in the last 20 years.
  • Walking is by far the main mode of travel within the City, with over 750,000 walked journeys a day. In recent years investment in cycling infrastructure has resulted in an estimated tripling in the number of people cycling in the Square Mile.

About Mapping for Change

Mapping for Change is a social enterprise, born out of the Extreme Citizen Science Research Group at University College London. MfC has amassed over 12 years’ experience in co-developing bespoke participatory programmes involving citizens, academics, public and third sector actors. MfC has used citizen science and participatory processes in a variety of contexts ranging from grassroots campaigns to large EU funded international research projects. We have delivered over 50 projects across the UK and Europe that have collated public perception; interpreted and presented results; traced impact; disseminated engagement activities and identified key areas for change, and ultimately provided communities with a voice.
