Since 2015, Equinix has quantified the total greenhouse gas (GHG) emissions from our direct and indirect operational activities at our data centers globally.
Our carbon emissions from direct energy consumption originate primarily from diesel generation used for backup power, onsite natural gas for heat and losses of HFC refrigerants from our chillers. Refrigerant losses were first quantified for the 2018 calendar year. To address our Scope 1 emissions, we are moving towards the use of natural refrigerants rather than HFC in our cooling systems.
Purchased electricity and a small amount of chilled water comprise our emissions from energy consumption. Equinix quantifies and reports the carbon footprint of its entire data center load including mechanical and electrical (M&E) overhead and customer IT equipment load. Our robust renewable energy strategy has driven down our Scope 2 emissions by 60% since 2015.
Equinix reports Scope 3 emissions from:
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 60% since 2015 on an absolute mtCO2e basis, even as our overall data center energy footprint and consumption has nearly doubled.
* Scope 2 (market-based) = 306,000 mtCO2e; Scope 2 (location-based) = 2,079,000 mtCO2e.
Equinix uses the WRI/WBSCD Greenhouse Gas Protocol to compute its carbon footprint associated with its operations and value chain. We disclose our climate data annually to the CDP Climate Change and Supply Chain Surveys. Our energy and renewable energy consumption, Scope 1, Scope 2 and most of its Scope 3 emissions are independently assured by Lucideon CICS to ISO 14064-3:2006 Standards for the quantification and reporting of greenhouse gas emissions.
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.
