C40 and McKinsey recently published ‘Focused Acceleration’, a report that aims to enable mayors to assess the ambition of their own climate plans against the modelled analysis produced by McKinsey and Arup. Still, according to C40, the same majors are now envisioning a future where walking, cycling and shared transport is how most citizens move around their cities. This shift towards zero-emission mobility will result in less congestion and less pollution while making our roads quieter and the air we breathe cleaner. Meanwhile, in the United Kingdom’s capital, things are getting real as to be concretised per the proposed article of C40. It is about London’s Mayor Sadiq Khan about to be launching a new air quality scheme through the use of sophisticated air monitoring system across London’s streets.

New ‘hyperlocal’ sensor network to create world’s most sophisticated air monitoring system across London’s streets

Sensors will be attached to lampposts, buildings and in dedicated Google’s Street-View cars. 

London, UK (21 June 2018) — The Mayor of London, Sadiq Khan, and C40 – a network of cities committed to bold action on climate change – have launched a cutting-edge new project to better understand Londoners’ exposure to air pollution around the city. Sensors will measure harmful pollution in tens of thousands of locations, making London’s new air quality monitoring network the most sophisticated in the world.  

Air pollution is threatening the health of Londoners, with most areas of the capital regularly breaking limits for safe levels of air pollution. Scientists estimate that thousands of Londoners’ lives end sooner than they should each year because of unclean air. And that the yearly cost of that dirty air to London’s economy is £3.7 billion.

London already has one of the best networks of air quality monitors of any city. Despite this, the network still does not cover enough of London. More sensors and more data are needed to say for sure which actions to tackle air pollution are working best. More sensors will also help explain how air quality changes not just because of the amount of traffic, but also because of other factors such as weather and road layout.

From July, new fixed and mobile sensors will be rolled out across London’s streets. 100 fixed sensors will be fitted to lampposts and buildings in the worst affected areas and sensitive locations, and two dedicated Google Street View cars will be driving across the city, mapping air pollution at an unprecedented level of detail. The two Google Street View cars assigned to this project will take air quality readings every 30 metres, building up a picture over the course of a year, and identifying pollution “hotspots” that the existing network of fixed monitors might miss.       

With this new ‘hyperlocal’ data, the Mayor will be able to track what actions are making the biggest difference to people’s health. Whether that’s more electric vehicles, or improvements to public transport, robust science means we will know more than ever about what works and what doesn’t when it comes to cleaning up our air.

Online maps showing data in real time will give Londoners information on just how dirty the air they breathe really is as they move around the city. These new tools will help the capital take action to tackle the most dangerous environmental threat to people’s health. The study will improve the accuracy of air pollution forecasts for the coming three days, making it possible for people to plan and respond to high pollution warnings.    

The project will be run by a team of air quality experts led by the charity Environmental Defense Fund Europe, in partnership with Air Monitors Ltd., Google Earth Outreach, Cambridge Environmental Research Consultants, University of Cambridge, National Physical Laboratory, and the Environmental Defense Fund team in the United States. King’s College London will also be undertaking a linked study focused on schools that will form part of the year long project.

The project is the result of a partnership between the Greater London Authority and C40 Cities.

The results from this initiative will be shared with the 96 members of the C40 Cities network, with the ambition of improving air quality for hundreds of millions of people living in cities around the world.

The announcement comes just a day after the Mayor brought together city leaders from across England and Wales for a national air quality summit, and unveiled that London will have the largest pure electric double-deck bus fleet in Europe.

The Mayor of London and C40 Vice Chair, Sadiq Khan, said: “London’s toxic air is leading to the premature deaths of thousands of Londoners every year so I am pleased that we are embracing the very latest smart technology to monitor hot-spots and demonstrate how effective our policies to combat this global issue are.

 

“I’m doing everything in my power to tackle London’s lethal air including cleaning up our bus and taxi fleets, introducing the Toxicity Charge for the oldest polluting vehicles in central London and bringing forward the introduction of the world’s first Ultra-Low Emission Zone to start in April 2019.

“I am delighted to be joining up with C40, the Environmental Defense Fund, Google and the rest of the team on this exciting project that will provide a treasure trove of new data and information to improve air quality here in London, and deliver an approach that can be replicated across the world.”

 

“This project will provide a step change in data collection and analysis that will enable London to evaluate the impact of both air quality and climate change policies and develop responsive interventions,” said Executive Director for Environmental Defense Fund Europe, Baroness Bryony Worthington.  “A clear output of the project will be a revolutionary air monitoring model and intervention approach that can be replicated cost-effectively across other UK cities and globally, with a focus on C40 cities.”

Mark Watts, C40, Executive Director said: “Almost every major city in the world is dealing with the threat of toxic air pollution, which is taking an incredible toll on the health of citizens, public finances, quality of life and contributing to climate change. London is already a world leader in responding to this global threat and with this initiative it will set a new global standard for how street level air quality monitoring can inform strategic policy making. Cities across the C40 network and around the world will be watching closely to understand how this street level air quality monitoring can deliver cleaner air for their citizens.”
