Corporate Environmental Responsibility Report & Greenhouse Gas Inventory

Location: Dallas

Client: AMR, parent company of American Airlines

Burns & McDonnell prepared a corporate environmental responsibility report in which a greenhouse gas (GHG) inventory was a critical component for American Airlines. View the report. The GHG inventory was conducted in accordance with industry protocols including the World Resource Institute Greenhouse Gas Protocol and addressed the six greenhouse gases required to be covered under the Kyoto protocol:

  • Carbon dioxide
  • Methane
  • Nitrous oxide
  • Hydrofluorocarbons
  • Perfluorocarbons
  • Sulfur hexafluoride

The inventory used the equity share approach in which assets owned by AMR, parent company of American Airlines, were covered in the inventory. Revenue ton miles (RTM), an indicator of both the number of passengers and distance flown was selected as an intensity factor measuring production levels. Using the intensity factor RTM demonstrated that greenhouse gas emissions on a normalized basis (accounting for RTM) decreased by approximately 20 percent from 2000 to 2006. GHG emission reductions were also estimated for various greenhouse gas projects completed over the past six years.
