David Lyon

Senior Scientist


Areas of expertise:
Oil and gas, methane science, emissions inventories

As a scientist, David works on EDF’s ground-breaking series of studies to quantify methane emissions from the natural gas value chain. His efforts include analyzing emissions data and researching technologies and policies to reduce natural gas leakage and minimize the climate impacts of natural gas development.


David worked for the Arkansas Department of Environmental Quality (ADEQ) as coordinator of the state’s air pollution emissions inventory program. While at ADEQ, David was project manager of an EPA funded study to study emissions and air quality impacts of natural gas development in the Fayetteville Shale. He also managed a half-million dollar project to develop and implement a web-based emissions inventory reporting system for a multi-state consortium of environmental agencies.

While in Arkansas, David was a leader in the Sierra Club and advocated for effective environmental regulations. He has experience teaching about air pollution and performing research in biogeochemistry and restoration ecology. His doctoral research was on the quantification, assessment, and mitigation of methane emissions from superemitters in the oil and gas supply chain.
