Properties and Emissions of Aerosols from the Transportation Sector

Overview 
The transportation sector, including ships, trains, and trucks, is a major source of particulate matter to the atmosphere, contributing to air quality and climate challenges in Canada and worldwide. Together with industrial partners and UBC collaborators, we quantify the emissions and properties of aerosols from the transportation sector and how these change with fuel type, technology, and operating procedures. 

We focus on understanding how aerosol chemistry and emissions evolve as transportation moves from conventional fossil fuels to sustainable alternatives such as biodiesel. The results are used with modeling developed by UBC collaborators to identify strategies for decarbonization and improved air quality. 

Why It Matters 
Transportation emissions affect urban air quality, human health, and climate. Understanding how new fuels and technologies change aerosol emissions helps guide effective pathways toward net-zero transportation systems. 

Key Questions or Goals 

• How do emissions and aerosol chemistry change as transportation shifts from fossil to renewable fuels? 
• How do operating conditions and technologies influence particle size, composition, and toxicity? 
• How can data from these studies inform models and policies for emission reduction and decarbonization? 

Approach / Methods 

• Combine field and laboratory measurements with advanced mass spectrometry and gas analysis 
• Conduct real-world testing to link engine operation and fuel type to aerosol composition and emission factors 
• Collaborate with modeling teams to connect measured emissions to regional air quality and decarbonization strategies
