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.

Valores estimados

Los informes de estimación del Alcance 2 proporcionan datos mensuales estimados de electricidad, energías renovables y emisiones antes de la publicación de métricas verificadas y finalizadas. Los valores se calculan utilizando los valores verificados por terceros del año anterior. Consulte la lógica detallada y los cálculos a continuación, teniendo en cuenta estas notas adicionales específicas para el informe de estimación del Alcance 2:

• Uso mecánico y eléctrico estimado (M&E): Calculado utilizando valores de PUE que pueden actualizarse con el tiempo a medida que se disponga de datos adicionales.

• Cobertura estimada de energía renovable: Estimada utilizando la cobertura de energía renovable del año anterior para cada instalación. Los valores finales verificados por terceros pueden diferir.

• Ubicación estimada y emisiones basadas en el mercado: Estimadas utilizando los factores de emisiones del año anterior para cada sitio. Los factores de emisiones finales verificados por terceros pueden diferir.

Los valores de los informes de estimaciones del Alcance 2 son estimaciones calculadas y están sujetos a cambios tras el inventario de gases de efecto invernadero de Equinix y la verificación de los datos de terceros. Equinix no garantiza que los valores estimados coincidan con los valores finales verificados. El uso de esta información para la presentación de informes formales queda a discreción del cliente. Se excluyen los sitios que abrieron durante el año de referencia debido a la disponibilidad incompleta de los datos.

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.

Uso de electricidad

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.

Uso de equipos de TI del cliente

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.

Los datos de consumo de electricidad de los equipos DE TI del cliente utilizados por la Herramienta de sostenibilidad se recopilan a través de la medición de energía de monitorización de circuitos de sucursal (BCM), cuando esté disponible. Los datos BCM se miden a nivel de circuito y se agregan en totales mensuales a nivel de jaula para su uso en la Herramienta de sostenibilidad. Para el pequeño número de sitios que no están habilitados para BCM y cualquier otra instancia en la que no hay un uso de energía con medición disponible para una jaula determinada, se estima el uso mensual DE TI.

Los cálculos de uso de TI BCM frente a no BCM se determinan del siguiente modo:

• Si se dispone de todos los datos de BCM para el periodo del informe, el uso de TI se calcula utilizando los datos medidos de BCM.

Se utiliza una mezcla de datos medidos por BCM y estimaciones basadas en el límite de consumo para estimar el consumo mensual a nivel de jaula cuando uno o más días del mes tienen datos de BCM pero faltan datos de BCM.

Si el MCB para el período de referencia está incompleto debido a la falta de totales mensuales o inexactos, se adoptan las siguientes medidas para estimar los totales mensuales:

• Si existen datos BCM para los meses que rodean al mes sin datos BCM, se utiliza una media de los dos meses de uso circundantes para el mes que falta.
• 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.

Los cálculos del consumo eléctrico de la BCM IT son los siguientes.

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.

En el panel general, el panel de control de Alcance 2 y el informe de energía verde, los valores de PUE utilizados en este cálculo se derivan de datos operativos verificados. Para los informes de estimaciones del alcance 2, los valores de PUE son preliminares y están sujetos a cambios a medida que se disponga de datos operativos adicionales.

Total Customer Electricity Usage

Total Renewable Energy

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

En el panel de información general, el panel de control de Alcance 2 y el informe de energía verde, el porcentaje de cobertura de energía renovable del sitio se verifica por terceros. Para los informes de estimaciones del alcance 2, estos valores son estimaciones preliminares basadas en la cobertura de energía renovable del año anterior y los factores de emisiones.

Emisiones de Alcance 1

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.

Emisiones del generador

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

Emisiones de gas natural

Emisiones de alcance 2

En el panel de información general, el panel de control de Alcance 2 y el informe de energía verde, los factores de emisiones basados en la ubicación y en el mercado se verifican por terceros. Para los informes de estimaciones del alcance 2, estos valores son estimaciones preliminares basadas en los factores de emisión del año anterior.

eficacia de uso energético

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.
