Database Development for Canadian Heavy-Duty Fleet

Project manager/technical lead for Environment Canada's project to develop on-road heavy-duty vehicle data by model/drivetrain/fuel between 2010 and 2025. The objective of this work was to collect historical data on new on-road heavy-duty vehicle sales and registrations in Canada, and to provide forecast data on new on-road heavy-duty vehicle sales in Canada. This data was developed to support the modelling and analysis of on-road heavy-duty vehicle GHG emissions and other air pollutants.

Technology Assessment for Canadian Light-Duty Fleet

Project manager/technical lead for Environment Canada's project on vehicle attribute and technology level information of the current Canadian light-duty vehicle fleets. This project prepared a database and provided an understanding of on-going technological changes in the Canadian light-duty vehicle sector.

Emission Inventory from On-road and Off-road Engines and Equipment

Technical lead for Electric Power Research Institute project to prepare criteria and GHG emission inventory from on-road vehicles, off-road equipment, marine and air traffic sources in Canada for different electrification penetration scenarios. This project included estimation of fuel consumption, electricity usage, and emissions from fossil fuelled and electric on-road vehicles and off-road equipment for different electrification scenarios between 2010 and 2050. On-road emissions were generated using the vehicle emission estimation model MOVES. GHG and CAC emission projections were made for low, nominal and high levels of vehicle electrification.

On-road Vehicle GHG Emissions Reductions from BC Regulations

Project manager/technical lead for BC Ministry of Environment project for the analysis of heavy duty on-road vehicle GHG reductions based on certain Regulations. This project included quantification of expected GHG reductions from 2007 to 2050 on-road heavy duty vehicles resulting from a suite of regulatory and non-regulatory policies and programs that will be in effect in BC including: Proposed Federal Heavy-Duty Vehicle and Engine Greenhouse Gas Emission Regulations; BC Carbon Tax; Renewable and Low Carbon Fuel Requirements Regulation (RLCFRR); Carbon Offset Aggregation Cooperative (COAC); Greenhouse Gas Reduction (Clean Energy) Regulation; and Other relevant policies or programs (such as conversion to natural gas vehicles) and reasonably foreseeable changes in diesel prices

GHG Emissions Assessment for STM, Montreal Quebec

Senior technical advisor for criteria air contaminants and GHG emissions assessment for STM in Montreal, Quebec. Provided direction to estimate emissions from activities related to public transportation systems in Montreal, including emissions from buildings, on- and non-road vehicles and vehicles running on renewable fuel.

Pathways of Motor Vehicle Emissions to Human Exposures

Technical lead for the development of improved methods for pathways of motor vehicle emissions to human exposures in significant micro-environments of exposure at the National Exposure Research Laboratory, USEPA, RTP, North Carolina.

Database Development for Canadian Light-Duty Fleet

Project manager/technical lead for Environment Canada's project to develop light-duty vehicle data by model/drive-train/fuel between 2009 and 2035. This work was carried out to support the development of regulatory emission standards for light-duty vehicles of model years 2017 through 2025 in Canada. The report presented the data sources, analysis of key trends, and details of the methodology employed in the development of the light-duty vehicle historical sales (2009 to 2011) and forecast sales estimates (2012 to 2035).

Trace Metals in Vehicle Exhaust

Project manager/technical lead for Health Canada’s project to investigate trace metals in vehicle exhaust. A major focus of this study was to identify links between metals emissions and the potential sources of the metal, such as ‘natural’ content of on-road diesel, gasoline and biofuels; fuel additives; lubricants; engine wear; and catalytic converter degradation.
