Interested in Joining our Team?

Aaron’s commitment to “leave no trace” began at an early age on his family’s mixed dairy farm in rural Saskatchewan. His career has focused on energy systems and greenhouse gas quantification, reporting, and verification. He is sought after for his expertise in devising strategies to bridge the gap between theoretical and practical implementation of methodologies focused on reducing greenhouse gas emissions. In addition to leading Brightspot’s growing team, Aaron is currently serving as convenor of ISO TC207/SC7/TG1, responsible for coordinating ISO’s suite of climate change mitigation standards.

When he’s not sitting at the computer, Aaron enjoys spending time outside the city with friends and family hiking, skiing, and traveling. You will find Aaron at the curling rink most weekends during the long Canadian winter.

A desire to better understand the world and make it a better place has been a driving force for much of Julie’s life. She has extensive experience interpreting climate-related policies, plans, and regulations in the Canadian and American contexts. She has expertise in greenhouse gas accounting, developing and verifying greenhouse gas emissions inventories, and providing consulting services related to market-based carbon reduction programs. More recently she has focused on helping clients understand climate risk and developing strategies to thrive.

Outside of Brightspot, Julie can be found on her bicycle, hiking with the dogs, or cheering from the sidelines at the hockey rink and soccer pitch.
