Upcoming Meeting: Non-exhaust emissions, 10.00- 12.00, Tuesday 30th October

City Hall, Committee Room 3

The next meeting of the APRIL group will focus on the hugely important topic of non- exhaust emissions.

The meeting will start with an update from Adam Moody (Transport for London) on current TfL understanding and approach to modelling non- exhaust. This we be followed by presentations from:

Professor Roy Harrison (University of Birmingham) will speak on the topic of “Field measurement and data analysis approaches to estimating non-exhaust emissions from road traffic.”

Daniel Wakeling (Ricardo) will speak on the topic of “The contribution of brake wear emissions to particulate matter in ambient air”. Daniel will also discuss how non-exhaust traffic emissions are covered in the in the Nation Atmospheric Emission Inventory (NAEI).


Meeting: Transport Group, 15:00 – 17:00, Wednesday 4th July

City Hall, Committee Room 5

As requested at the last meeting of the Transport Group this session will focus on Electric Vehicles (EVs) and EV infrastructure.

The meeting will start with an update from Oliver Lord (Deputy Air Quality Manager, GLA) on current GLA thinking and policy around EV charging followed by:


Sujith Kollamthodi (Ricardo Energy & Environment),Creating a dense public charging network in Brighton to accelerate the adoption of electric vehicles 

Ricardo – Dense charging network for Brighton_04-07-18

Brighton is well positioned to play a leading role in accelerating the adoption of electric vehicles (EVs) as Brighton’s local politicians, across the political spectrum, have supported the “greening” of the city and sustainable mobility strategies. However, a significant proportion of households in Brighton do not have access to off-street parking, which means that consumers interested in purchasing electric vehicles would not have ready access to nearby residential charging.  Brighton is also keen to accelerate the deployment of electric taxis in the city, but sufficient and well-positioned rapid charging infrastructure is required to support this transition.  This project identified suitable locations for installing large numbers of on-street residential and destination charge points as well as identifying locations for introducing DC rapid charging infrastructure to support electric taxis. The analysis into account the locations where the next tranche of EV purchasers are likely to live, the most appropriate locations for taxi charging, and importantly locations in Brighton where there is sufficient local electricity grid capacity to install charge points without the need for investing in costly grid reinforcement.


Sara de la Serna (SSE), London EV charging infrastructure: an SSE perspective

SSE- London EV charging infrastructure an SSE perspective

This presentation explores SSE activity in the EV sector, through the deployment of public charging infrastructure (Source London) and charging infrastructure at bus depots, and how it makes a positive contribution to the city’s air quality issues


Jack Lewis Wilkinson (UK Power Networks), Celine Cluzel & Tristan Dodson (Element Energy) Recharge the Future interim findings:  EV charging behaviour and impact on load growth

UK Power Networks- Recharge the Future- Interim Findings

Recharge the Future aims to model EV load growth, and assess the impacts that this load growth will have on the need to reinforce UKPN’s distribution networks. The project has analysed the latest trial data and carried out an in depth study of EV charging behaviour. This has enabled the team to develop one of the most advanced EV forecasting tools in the world; which is able to model the complex geospatial variance of EV uptake & charging behaviour. This presentation will summarise the findings so far, namely: the charger use study & the results from the load forecasting model.

Meeting on low-cost sensors: Tuesday 17th April, 09:30- 16:00, National Physical Laboratory

Teddington, London TW11 0LW

In the last few years there has been a rapid growth in the development and availability of low-cost sensors for measuring pollutant concentrations. The purpose of this meeting is to review the range and performance, current and future applications, and appropriate uses of such equipment. In addition to the main speakers we would like to invite short contributions from those currently using low-cost sensors in monitoring and research. We hope that this meeting will encourage networking and collaboration between those developing, testing and applying low-cost sensors.

Meeting: Transport Group- Friday 16th March, 14.00, City Hall (CR3)

!! This meeting was been postponed to Friday 16th March due to bad weather!!

Mark Peckham from Cambustion will present some recent data recorded using their fast response emissions analyzers from on-board a variety of vehicles.  The data from TfL’s “West London” route shows the impact of urban driving and the accurate position of pollution “hot spots” caused by speed bumps, harsh accelerations, engine warm-up and general sub-optimal engine operation.  A comparison is made between various ages of vehicles and their NOx polluting characteristics.

A second presentation will be ‘Shipping emissions in the London Context’.  Aether will be presenting on their recent work for the Port of London Authority, which informed the Authority’s first draft air quality strategy.  The work involved the development of a “port wide” shipping emissions inventory and on-board vessel emission testing.

Finally, there will be a short presentation on some current policy initiatives from the GLA.

Past meeting: APRIL transport and health groups on 19 June 2017

This was a joint meeting of APRIL Transport and Health groups. The speakers were Dr Audrey de Nazelle, from Imperial College London, on active travel, air pollution and health; and David Talbot, from Transport for London, on the eLIPTIC (Electrification of public transport in cities) project. This project is looking at using the spare capacity of London Underground electricity network for recharging Surface Transport Electric Vehicles (buses, support fleet vehicles, etc.).

Past meeting: APRIL Transport meeting on 7 March 2017

There were three presentations at this meeting. Rosalind O’Driscoll, from Imperial College London, spoke about real world NOX and CO2 emissions from modern petrol and diesel passenger cars. Finn Coyle, from Transport for London, then talked about retrofitting TfL buses to meet the Euro VI standard. The third presentation was by Gloria Esposito, from the Low Carbon Vehicle Partnership, about the design of the Clean Vehicle Retrofit Accreditation Scheme.
