Katlyn MacKay

Post-Doctoral Fellow, Canada Oil and Gas Emissions


Areas of expertise:
Methane emissions, gas measurement, inventories and field work

As a Post-Doctoral Fellow at EDF, within the Office of the Chief Scientist, Katlyn works on improving understanding of oil and gas methane emissions in Canada. She helps with our Canadian measurement campaigns, and is leading a large synthesis effort to estimate total oil and gas supply chain methane emissions in Canada using the best available data.


Katlyn has over 7 years of experience in measuring methane emissions across the oil and gas industry. She has previously participated in projects related to knowledge translation, training, and controlled release testing, alongside many of Canada’s major oil and gas companies and several prolific sensor manufacturers. Her PhD research focused on collecting and analyzing methane measurements to better understand emission patterns and magnitudes across Canada’s oil and gas sector, and to improve national inventory estimates and modeling.
