Inventory

TI calculates its greenhouse gas (GHG) emissions inventory using the guidelines of the World Resources Institute's (WRI) GHG Protocol. It includes direct (scope 1) and indirect (scope 2) emissions of six types of gases included in the Kyoto Protocol:
  • Carbon dioxide (CO2).
  • Methane (CH4).
  • Nitrous oxide (N2O).
  • Hydrofluorocarbons (HFCs).
  • Perfluorocarbons (PFCs).
  • Sulphur hexafluoride (SF6).
We also include nitrogen trifluoride (NF3) in our GHG emission inventory calculations.

In addition to the WRI's GHG Protocol, we calculate our inventory using the Intergovernmental Panel on Climate Change's Tier 2B methodology for scope 1 emissions. This includes accepted quantification methods, emission factors and global warming potential. TI has not yet conducted external verification of this data and does not have plans to do so in the near future; however, we have had third-party verification of our data-collection process and methodology.

Our carbon footprint calculation includes all owned and leased TI sites larger than 50,000 square feet. This accounts for 97 percent of our total square footage and more than 99 percent of our equivalent carbon dioxide (CO2e) emissions. It does not include any subcontractor or supplier manufacturing facilities or facilities smaller than 50,000 square feet, whether owned, leased or controlled by TI. In addition, the calculation does not include National Semiconductor facilities that we acquired in late 2011. We plan to disclose the performance of these sites in future reporting efforts.

TI currently does not include scope 3 emission reductions (such as emissions from supply chain, waste or business travel) in our formal GHG emissions inventory. However, we have begun measuring business air-travel emissions from TI's private jets for flights into, within or out of Europe as part of the region's GHG Emissions Trading Scheme. We also track employee commute activities through our Commute Solutions program.
