Case Study

Carbon Management Services (US)

SLR has been providing environmental consulting services to a major U.S. airline since 2003. In 2008, the airline selected SLR to assist them in broader environmental programs, including carbon management services.  We initially conducted a baseline assessment of the carbon footprint for the client’s operations and compared the results to industry operation carbon metrics.

Confidential Airline Client



Project Objectives:

SLR helped the client prepare an environmental report for their website that helped inform their customers of their significant efforts to reduce their ecological and carbon footprints.  SLR currently calculates the client’s greenhouse gas (GHG) emissions on an annual basis.

Our Role

SLR undertook the following works:

  • Calculated the annual total GHG emissions of their operations and the operations of a subsidiary regional U.S. airline for the period of 2004 through 2012
  • The GHG emissions inventory included direct emissions from aircraft, ground support equipment, and facility heating, and indirect emissions from electricity usage. The calculated GHG emissions were compared to productivity metrics to account for changes in air travel demand and operational capacity
  • Assisted in writing all of the airline’s environmental programs for their website and Corporate Environmental Responsibility Report
  • Trends of GHG operational efficiency were determined for both the buildings and aircraft. Building energy efficiency, calculated as total energy per square foot, was determined from 2006 to 2012. Aircraft fuel efficiency per passenger-mile was calculated and compared to the top 10 domestic airlines from 2009 to 2012
