Inventory

TI calculates its greenhouse gas (GHG) emissions using guidelines from the World Resources Institute (WRI). 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 guidelines, 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. We do not currently obtain external verification of this data; however, we have obtained third-party verification of our data-collection process and methodology.

Our carbon footprint calculation includes all owned and leased sites larger than 50,000 square feet, as well as the former National Semiconductor sites we acquired in late 2011. 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.

TI currently does not include scope 3 GHG emissions (such as emissions from our supply chain, waste generated by TI 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 European Union countries in anticipation of potential requirements under the region's GHG Emissions Trading Scheme. We also track certain employee commute activities through our Commute Solutions program.
