Happily, I’m able to say that the work I do helps the environment and people and not the other way around.
Roger Chang is a senior environmental scientist with more than 22 years’ experience creating critical mobile source emission inventories for offroad vehicles, commercial marine vessels, aircrafts, and locomotives using a wide variety of modeling programs. He specializes in developing aircraft emission inventories using the Federal Aviation Administration’s Aviation Environmental Design Tool, which he helped test during its development and has used repeatedly ever since. For over two decades, he has supported the aviation component of the U.S. Environmental Protection Agency’s National Emissions Inventory, which covers approximately 20,000 facilities ranging from small landing strips to large international airports. Roger also used FAA’s NextGen air traffic data to develop 3-dimensional helicopter emission inventories for the Bureau of Ocean Energy Management.
To pinpoint, analyze, and reduce emissions from marine vessels, Roger has compiled automatic identification systems data to serve marine emission inventories for EPA and BOEM at the federal level, and for the state of Texas’s port, shipping channel, and water inventories. For EPA’s partnership with the Port of Everglades, he has helped evaluate initiatives to reduce emissions by reducing the speed of vessels approaching the port and incentivizing the replacement of older vessels and engines with higher-tier engines. He has also conducted shore power feasibility studies for vessels visiting ports in the Salish Sea. Roger has supported the rebuilding of BOEM’s offshore wind power air tool to estimate emissions from both vessels and helicopters involved with the construction, operation, and maintenance of offshore wind farms, as well as the anticipated reduction in power demand for landside Energy Generating Units associated with power provided from offshore facilities. In addition, Roger manages ERG’s support to EPA’s Wood Heater Certification program and leads ERG’s team in reviewing applications submitted by manufacturers in compliance with the Standards of Performance for New Residential Wood Heaters, New Residential Hydronic Heaters, and Forced-Air Furnaces.
Roger holds a B.A in environmental studies from the University of Chicago and an M.E.M in water and air resources in environmental management from Duke University. He currently lives in Virginia with his wife and two daughters and spends time coaching soccer and volunteering at the Vienna Moose Lodge and other local charities.
