Emissions inventories

Rachel leads a team of 30 talented and dedicated individuals working to provide scientifically robust evidence on the emissions of air pollutants and greenhouse gases, underpinning a wide range of reporting requirements and policy making in the UK and beyond. She has responsibility for managing a portfolio of projects, business development activities and investments work, ensuring the quality and timeliness of outputs to customers. Rachel has an environmental chemistry background and has worked in air quality consultancy for over 20 years, leading high value, strategic and complex projects for National Governments and the European Commission.

Yvonne is Ricardo’s sector lead for emissions of GHGs and air quality pollutants from mobile combustion sources, including all types of transport modes and non-road mobile machinery. She has 15 years’ experience in this field and has been involved in the design and development of Ricardo’s Road Transport model, which is used for UK scenario modelling and mandatory UK and international reporting, including mapping 1x1km gridded emissions, road emissions, local authority CO₂ and road transport fuel consumption inventories, EU and UK Government air quality compliance, NO₂ air quality plans and local air quality management datasets. As a highly regarded expert she is frequently invited to review the inventories of other countries.

Glen is the technical lead for the UK National Atmospheric Emissions Inventory with over 20 years’ experience in inventory system and model quality assurance, management and improvement, implementing international guidance (IPCC, EMEP-EEA) for inventory models, at the national, sub-national to city level. Glen’s core expertise is GHG and air quality pollutant emissions from energy (combustion, fugitive) and industrial process sources. He is a UNFCCC lead reviewer, IPCC author and has extensive knowledge of inventory data, methods and systems, skilled at leading expert teams to identify and address key underlying issues (e.g. data access, method selection, uncertainty analysis).

Ioannis is an expert in the analysing spatial environmental data, with a focus on climate, emissions, energy, transport, and other geospatial datasets. He provides technical support and advice to the governmental departments in the UK and overseas, for the development of national and regional Air Quality and Greenhouse Gas policies. He has an extensive experience in Geographical Information Systems and leads a team of experts that generates high geospatial resolution historic timeseries and future projections of emissions and energy use.
