Since 2015, we have been transparently reporting energy, carbon and renewable energy metrics. Our greenhouse gas (GHG) or carbon emissions from direct energy consumption (Scope 1) originate primarily from diesel generation used for backup power, onsite natural gas usage for heat and losses of HFC refrigerants from our chillers. Refrigerants losses were first quantified for the 2018 calendar year. Purchased electricity and chilled water comprise our Scope 2 emissions from indirect energy consumption. We are currently gathering data to disclose our full inventory of Scope 3 emissions, and we currently verify Scope 3 emissions from business activities, including: employee commuting, air travel, rental cars and rail travel, as well as hotel stays booked through our corporate travel agency.
Equinix’s growing share of renewable energy across its global portfolio has resulted in a significant reduction in our annual disclosed carbon emissions. When computed using The Greenhouse Gas Protocol’s Scope 2 market-based guidance, our emissions fell 71% since 2015 on an absolute Market-based mtCO2e basis (766,100 mtCO2e to 224,000 mtCO2e).
At Equinix, we are committed to the responsible management of all resources. Energy efficiency and environmental sustainability are part of everything we do, whether we’re building new data centers or upgrading existing facilities.
