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.

预估值

范围2估算报告提供月度估算电力，可再生能源和排放量数据，然后发布最终核实的指标。数值使用上一报告年度的第三方验证值计算得出。请参考以下详细逻辑和计算，并谨记特定于范围2估算报告的附加说明：

• 估算的机械和电气(M&E)使用率–使用PUE值计算，该值可能随着其他数据的可用而更新。

• 预估可再生能源覆盖率–使用每个站点上一年的可再生能源覆盖率估算。第三方验证的最终值可能不同。

• 各网点和市场的预估排放量–使用每个站点上一年的排放系数估算。第三方核实的最终排放系数可能不同。

范围2估算报告中的数值是计算的估算值，在Equinix温室气体清单和第三方数据核实后可能会发生变化。Equinix不保证预估值与最终验证值匹配。将此信息用于正式报告由客户自行决定。由于数据可用性不完整，在报告年份内开设的站点不包括在内。

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.

Electricity Usage

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.

客户 IT 设备使用情况

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.

可持续发展工具使用的客户IT设备用电数据通过分支电路监控(BCM)功率计量来收集(如适用)。BCM数据在电路级别进行计量，并累计为月度机笼级别总量，以供可持续发展工具使用。少数站点未启用BCM，以及给定机笼无法使用计量电源的任何其他实例，则将估算每月IT用量。

BCM 与非 BCM IT 使用情况的计算方法如下：

• 如果报告期内所有 BCM 数据均可用，则使用计量的 BCM 数据计算 IT 使用情况。

当一个月中有一天或多天有 BCM 数据，但有一天或多天缺少 BCM 数据时，将使用 BCM 计量数据和基于取水上限的估算值的组合来估算每月的笼级使用量。

如果由于月度总数缺失或不准确而导致报告期内的业连管不完整，请采取以下步骤估算月度总数：

• 如果当月存在BCM数据，但没有BCM数据，则将使用周边两个月的平均使用率计算缺失月份。
• 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 用电量计算如下。

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.

在概述控制面板，范围2控制面板和绿色能源报告中，此计算中使用的PUE值源自经验证的运营数据。对于范围2估算报告，PUE值为初步值，可能随着其他运营数据的可用而更改。

Total Customer Electricity Usage

Total Renewable Energy

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

在概述控制面板，范围2控制面板和绿色能源报告中，站点可再生能源覆盖率百分比由第三方验证。对于范围2估算报告，这些值是基于上一年可再生能源覆盖率和排放系数的初步估算值。

范围 1 排放

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.

发电机排放

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

天然气排放

范围 2 排放

在概述控制面板，范围2控制面板和绿色能源报告中，基于网点和市场的排放系数由第三方核实。对于范围2估算报告，这些值是基于上一年排放量系数的初步估算值。

电源使用效率

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.
