Sustainability Tool Methodology

This topic details the Equinix methodology used for calculating data that appears in the Sustainability Tool. This data includes customer allocated greenhouse gas (GHG) emissions related to customers' use of Equinix co-location services and site-level Power Usage Effectiveness (PUE). Calculated GHG emissions and PUE are made available to customers in the Equinix Sustainability Tool tab located within the Customer Portal.

Greenhouse Gas Accounting​

Equinix conducts its annual greenhouse gas emissions accounting process in accordance with the World Resources Institute (WRI) Greenhouse Gas Protocol's (GHGP) Corporate Accounting and Reporting Standard. Corporate energy, renewable energy and greenhouse gas emissions data are externally verified by a third party in accordance with Limited Assurance ISO 14064-3 Standards.

Location- and market-based greenhouse gas emissions factors for each of Equinix's approximately 270 International Business Exchanges (IBXs) are identified annually as a part of Equinix's ongoing greenhouse gas accounting program. Location-based emissions factors are derived from data sets published by government agencies and/or from other publicly available sources relevant to the geographic location of each individual IBX. For market-based emissions calculations, Equinix uses emissions factors from our relevant electricity suppliers if available and applies emissions factors related to Energy Attribute Certificates or related to renewable energy procured directly for each IBX, as applicable. Sites that are 100% covered by renewable energy can claim zero associated market-based emissions.

Equinix follows best practice as defined by the Greenhouse Gas Protocol in sourcing our emissions factors. As this dataset is prepared by a third-party consultant for Equinix's use, we are not able to disclose it publicly.

Organizational Reporting Boundary​

Equinix uses the operational control approach as defined by the Greenhouse Gas Protocol to define our organizational boundary for emissions accounting. As generator, fugitive, and natural gas emissions occur as a result of onsite activities under Equinix's control, Equinix reports on these emissions within our (Equinix's) Scope 1. As Equinix controls the power purchased at sites, Equinix reports on the carbon impact of purchased electricity for customer IT equipment and mechanical and electrical (M&E) overhead as within our (Equinix's) Scope 2 emissions. Therefore, Equinix procures renewable electricity coverage for electricity consumption at our sites and retires associated Energy Attribute Certificates in Equinix's name.

Green Power Reports can serve as an attestation of the retired renewable energy against electricity consumption at our sites and can be used by our customers as evidence of decarbonization of their attributed electricity emissions at the site in market-based accounting.

Logic and Calculations​

The Sustainability Tool contains calculated electricity usage, greenhouse gas emissions, and Power Usage Effectiveness (PUE) metrics. Calculation methods for the metrics that fall within these categories are detailed in this section.

電力使用量​

Customer electricity usage falls into two categories: customer IT equipment electricity usage and overhead M&E electricity usage. Customer IT equipment electricity usage is the electricity consumed by the customer's equipment deployed within Equinix facilities. Overhead M&E electricity usage is the portion of overhead electricity usage for the site allocated to the customer. M&E usage is calculated in accordance with ISO 30134 standards.

お客様のIT機器の使用量​

Customer IT Equipment Electricity Usage will, in most cases, match power usage in customer power usage reporting. Differences may occur due to estimation logic present in the Green Power Report.

Customer power usage is pulled from Equinix databases based on contract data: for each cage that was active during the reporting year, the Sustainability Tool seeks out consumption data for that contract.

サステナビリティツールが使用するお客様のIT機器の電力使用量データは、利用可能な場合、分岐回路監視(BCM)電力計を通じて収集されます。BCMデータは回路レベルで測定され、毎月のケージレベルの合計に集計され、サステナビリティツールで使用されます。BCMに対応していない少数のサイトや、特定のケージで従量制の電力使用量が利用できないその他の場合は、月ごとのIT使用量が推定されます。

BCMと非BCMのIT使用量の計算は、以下のように決定される：

  • 報告期間中にすべてのBCMデータが入手可能な場合、IT使用量は測定されたBCMデータを使用して計算される。

BCMのデータがある月が1日以上あるが、BCMのデータがない日が1日以上ある場合、BCMの計測データとドローキャップに基づく推定値をミックスして、月間のケージレベルの使用量を推定する。

月次合計が不足している、または不正確であるために報告期間のBCMが不完全である場合、月次合計を推定するために次の手順が実行されます。

  • BCMデータが存在しない月のBCMデータが存在する場合、欠落している月の前後2か月の平均使用量が使用されます。
  • If data does not exist on either side of the missing month, but exists for the previous three months, an average of the previous three months' data is used for the missing monthly total.
  • If there are no available values for the previous three months, but there is an available value four months prior, this value is used for the missing monthly total.
  • If none of these options are available, the missing monthly total is estimated using customer draw cap.

BCM ITの電力使用量の計算は以下の通り。

Customer Overhead M&E Usage​

M&E overhead electricity usage is allocated to each customer based on the intensity of their IT consumption relative to the site's total IT consumption. M&E consumption is calculated as follows, where Power Usage Effectiveness (PUE) is total site IT electricity consumption divided by total site electricity consumption.

概要ダッシュボード、スコープ2ダッシュボード、およびグリーン電力レポートでは、この計算に使用されるPUE値は検証済みの運用データから算出されます。スコープ2の見積りレポートの場合、PUE値は暫定値であり、追加の運用データが利用可能になると変更される可能性があります。

Total Customer Electricity Usage​

Total Renewable Energy​

Total renewable energy is the portion of total electricity consumption covered by Equinix's renewable energy purchases.

概要ダッシュボード、スコープ2ダッシュボード、およびグリーン電力レポートでは、サイトの再生可能エネルギーカバレッジの割合が第三者によって検証されています。スコープ2見積りレポートでは、これらの値は、前年の再生可能エネルギーカバレッジと排出係数に基づいた暫定的な推定値です。

スコープ1排出量​

Scope 1 emissions are allocated to customers based on the intensity of their IT consumption relative to the site's total IT consumption. Relevant Scope 1 emissions sources include natural gas, generator consumption (diesel or hydrotreated vegetable oil fuel), and refrigerant leakage. Data can be displayed for a 12-month period, with generator and refrigerant emissions evenly distributed across each month for reporting purposes.

Not all sites will have nonzero values for emissions related to these three activities every year:

  • Not all sites use natural gas for heating. In the case where a customer does not have presence in sites where natural gas is used for heating, natural gas emissions will show as "N/A."
  • As generator consumption and refrigerant leakage are intermittent activities, "0" is an expected and valid value.

発電機排出量​

Generator emissions occur when backup generators are utilized due to an outage onsite. hydrotreated vegetable oil is relevant for Generator Consumption at MA5, PA4, and SK1; all other sites use diesel in their backup generators.

Fugitive Emissions​

スコープ2排出量​

市場ベースの排出量​

電力使用効率​

The Sustainability Tool provides site-level, rolling 12-month Power Usage Effectiveness average (PUE12). PUE12 is available only for sites that have been operational for a full year. Equinix calculates Power Usage Effectiveness in accordance with Category 1 of the ISO/IEC 30134-2 standard.

Data and Logic Changes​

Equinix continually strives to improve the quality of data we provide to customers. To this end, we periodically make changes to our backend data and product logic that may result in differences between historically provided reports and newly generated reports. In most cases, any differences that result from these methodology refinements will be small, but questions or concerns may be submitted via a Customer Portal support ticket.
