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

Os Relatórios de Estimativa do Escopo 2 fornecem dados mensais estimados de eletricidade, energias renováveis e emissões antes do lançamento de métricas finalizadas e verificadas. Os valores são calculados utilizando os valores verificados por terceiros do ano de relatório anterior. Consulte a lógica detalhada e os cálculos abaixo, tendo em mente estas observações adicionais específicas para o Relatório de Estimativa do Escopo 2:

• Uso Estimado de Mecânica e Elétrica (M&E) - Calculado usando valores de PUE que podem ser atualizados ao longo do tempo à medida que dados adicionais se tornam disponíveis.

• Cobertura Estimada de Energia Renovável – Estimada usando a cobertura de energia renovável do ano anterior para cada local. Os valores finais verificados por terceiros podem ser diferentes.

• Emissões estimadas no local e no mercado – Estimadas usando os fatores de emissões do ano anterior para cada local. Os fatores de emissões finais verificados por terceiros podem diferir.

Os valores nos Relatórios de Estimativa do Escopo 2 são estimativas calculadas e estão sujeitos a alterações após o inventário de gases do efeito estufa da Equinix e a verificação de dados de terceiros. A Equinix não garante que os valores estimados correspondam aos valores finais verificados. O uso dessas informações para relatórios formais fica a critério do cliente. Os sites que abriram durante o ano do relatório são excluídos devido à disponibilidade de dados incompletos.

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 eletricidade

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 equipamentos de TI do 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.

Os dados de uso de eletricidade do equipamento DE TI do cliente utilizados pela Ferramenta de Sustentabilidade são coletados por meio da medição de energia do BCM (Branch Circuit Monitoring, monitoramento de circuito de ramificação), quando disponível. Os dados do BCM são medidos no nível do circuito e agregados em totais mensais no nível do compartimento para uso na Ferramenta de Sustentabilidade. Para o pequeno número de sites que não são habilitados para BCM e quaisquer outras instâncias nas quais nenhum uso de energia medido está disponível para um determinado compartimento, o uso mensal DE TI é estimado.

Os cálculos de uso de TI BCM versus não BCM são determinados da seguinte forma:

• Se todos os dados do BCM estiverem disponíveis para o período do relatórios, o uso de TI será calculado usando dados do BCM medidos.

Uma mistura de dados medidos do BCM e estimativas baseadas no limite de consumo é usada para estimar o uso mensal no nível da gaiola quando um ou mais dias do mês têm dados do BCM, mas um ou mais dias não têm dados do BCM.

Se o BCM para o período de relatório estiver incompleto devido a totais mensais ausentes ou imprecisos, as seguintes etapas serão tomadas para estimar os totais mensais:

• Se existirem dados BCM para os meses em torno do mês sem dados BCM, uma média do uso dos dois meses em torno será usada para o mês ausente.
• 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.

Os cálculos para o uso de eletricidade da BCM IT são os seguintes.

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.

No Painel de visão geral, no Painel do escopo 2 e no Relatório de energia verde, os valores de PUE usados nesse cálculo são derivados de dados operacionais verificados. Para Relatórios de Estimativa do Escopo 2, os valores de PUE são preliminares e estão sujeitos a alterações à medida que dados operacionais adicionais se tornam disponíveis.

Total Customer Electricity Usage

Total Renewable Energy

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

No Painel de visão geral, no Painel do escopo 2 e no Relatório de energia verde, a porcentagem de cobertura de energia renovável do local é verificada por terceiros. Para os Relatórios de Estimativa do Escopo 2, esses valores são estimativas preliminares com base na cobertura de energia renovável e nos fatores de emissões do ano anterior.

Emissões de escopo 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.

Emissões do gerador

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.

eficiência energética

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.
