1 Historical data has been restated due to improvements in data collection, analysis and reporting methodology.

2 In 2018 and going forward, we include satellite traffic in our total network traffic. Prior to this addition, our 2018 GHG intensity metric would have been 52.2 metric tons CO2e/petabyte. Learn more about how we calculate total traffic for our GHG intensity in our Energy Management issue brief.

3 Electricity use is a proxy for total energy use. In 2018 and going forward, we include satellite traffic in our total network traffic. Prior to this addition, our 2018 energy intensity metric would have been 100 MWh/petabyte. Historical data has been restated due to improvements in data collection, analysis and reporting methodology. Learn more about how we calculate total traffic for our energy intensity in our Energy Management issue brief.

4 Historical data has been restated due to improvements in data collection, analysis and reporting methodology. Additionally, beginning in 2017, we incorporated the production and consumption of our alternative and renewable energy portfolio (on-site solar and fuel cell energy, purchased wind) into our data.
