Taryn Ferguson, Greater London Authority

Expanding London’s Ultra Low Emission Zone

Taryn is passionate about active and sustainable transport and the ways in which cities can encourage residents to choose these modes more often. This interest led Taryn to leave her job in food and drink consumer research to join the Greater London Authority, working first on walking and cycling policy, and now on air quality, specifically addressing road transport emissions.

Taryn worked closely with Transport for London to deliver the Ultra Low Emission Zone expansion in October 2021 and is continuing to work with internal and external partners to develop the next steps for reducing harmful emissions from road transport in London.

Taryn also leads the GLA Air Quality Team’s collaboration with London’s health system to help raise public awareness of the serious health consequences of exposure to air pollution and the ways individuals can reduce both their exposure and contribution to pollution.

Dr Mark Peckham, Cambustion Ltd

How “gross emitting” vehicles can spoil local air quality

Mark graduated from the University of Edinburgh in 1990 with a 1^st class degree in Mechanical Engineering, going on to complete a PhD at Emmanuel College, Cambridge on “In-cylinder sampling of unburned hydrocarbons”.  After a brief spell with Ricardo, Mark returned to Cambridge in 1994 to work for Cambustion, becoming a director in 1997.  He now heads-up their fast gas analyzer division, developing instruments for applications such as respiration, pollution detection and other rapid processes which benefit from real time measurements.

Naomi Farren, University of York

New evidence on ammonia emissions from road vehicles based on comprehensive remote sensing data

Naomi Farren is a postdoctoral researcher at the University of York. Her research focuses on developing new techniques to measure on-road vehicle emissions and interpret their contribution to urban air pollution. She has an interest in characterising vehicular sources of ammonia to strengthen the evidence on their role in particle formation and impact on nitrogen deposition. As part of a collaboration between the University of York and Ricardo, Naomi has used the UK remote sensing database to estimate total UK ammonia emissions from road vehicles. She has investigated the complex mix of factors influencing vehicular ammonia emissions, including fuel type, after-treatment technology, and engine temperature.

James Hobday, Emissions Analytics

What’s in a tyre?

James began his career at the Financial Times before joining Integer Research in 2009 specialising in the vehicle emissions market, specifically SCR market development. As Business Development Director at Emissions Analytics, James works with a range of stakeholders, including governments, manufacturers, technology specialists, oil companies and research institutions relating to exhaust emissions, in-vehicle air quality and tyre particulate emissions.
