Equinix named global leader in data centre sustainability

Equinix has been named a Leader in a new global assessment of data centre sustainability by research group IDC MarketScape.

The study is IDC's first worldwide evaluation of sustainability practices among data centre services providers. It assesses strategy and execution over a three to five-year period and in the near term.

The report places Equinix in the Leaders category. The researchers cite the company's focus on renewable energy, water management, circularity, waste heat export and green financing.

According to IDC, these areas form part of what it describes as a broad sustainability strategy at Equinix. The assessment highlights both current performance metrics and longer-term net-zero commitments.

"Equinix has demonstrated leadership in sustainable data centre operations," said Olga Yashkova, Research Manager, Enterprise Workloads and Datacenter Infrastructure, IDC. "Its comprehensive strategy - from renewable energy sourcing and water stewardship to circularity, heat export and green financing - positions Equinix as a Leader and a trusted partner for organisations seeking to decarbonise their digital infrastructure and address business and regulatory requirements."

Equinix operates more than 270 data centres across 77 metropolitan areas in 36 countries. These sites act as connectivity hubs for enterprises, cloud providers and AI workloads.

The report notes that the company applies sustainability initiatives and energy and water management programmes across this network. It also notes regional examples where specific metrics have shifted year on year.

Heat reuse growth

IDC cites waste heat reuse as one area of progress. Equinix exported 14.5 GWh of residual heat from its data centre operations in 2024.

This represented a 245% increase over the previous year. Sites in Helsinki, Toronto and Paris supplied excess thermal energy into municipal district heating systems and local community facilities.

The report links this export activity with broader circularity efforts inside the data centres. It also frames the schemes as part of urban energy planning in those cities.

Water and energy metrics

The study highlights Equinix's water focus programme for cooling. The company reported an average Water Usage Effectiveness of 0.95 in 2024.

Equinix issues customer-facing water reports. It also deploys engineering measures such as water-free energy sources, thermal storage and reuse schemes in water-constrained markets.

On energy efficiency, the company reported a global annualised average Power Usage Effectiveness of 1.39 in 2024. This was a 6% improvement compared with the prior year.

Some individual sites have lower PUE figures. Equinix has set a target for a global average PUE of 1.33 by 2030.

Net-zero and renewables

Equinix has a net-zero emissions goal across its value chain by 2040. The Science-Based Targets initiative has validated this target.

The company aims to cut absolute Scope 1 and 2 emissions by 90% and Scope 3 emissions by 90% from a 2019 baseline. It plans to maintain growth in its data centre footprint while it works towards these reductions.

Equinix has committed to 100% clean and renewable energy coverage by 2030. It reported 96% coverage worldwide in 2024.

The company states that its operations in the Americas and EMEA already reached 100% coverage last year. It continues to add power purchase agreements and other procurement tools in remaining regions.

AI and infrastructure

The IDC assessment also notes the link between AI expansion and resource use in data centres. It points to the role of renewable energy in supporting AI workloads at scale.

Equinix has built edge AI infrastructure on its existing sites. It runs turnkey distributed AI solutions that draw on the company's renewable energy coverage and its efficiency measures.

"Equinix is uniquely positioned to meet the increased market demand for sustainable digital infrastructure solutions," said Christopher Wellise, Vice President, Sustainability at Equinix. "Our decades of pioneering new sustainability breakthroughs, combined with our next-generation energy solutions and enhanced operational efficiencies, are setting new industry standards and enabling our customers' success around the world."

Green finance push

IDC identifies green financing as another differentiator for Equinix. The company has issued more than USD $9 billion in green bonds since 2020.

It has allocated about USD $4.9 billion of this to green buildings, renewable energy and energy efficiency projects. Funding also supports the development of sustainable data centre facilities and technologies such as fuel cells for onsite power generation.

Equinix provides customers with customised sustainability reporting. The reports include detailed figures on electricity consumption, renewable energy coverage, carbon emissions and water use.

The company says these instruments allow customers to track their own decarbonisation progress. They also allow clients to respond to tightening regulatory disclosure rules in multiple regions.

Australian focus

Equinix has linked the global recognition to national policy debates in some markets. In Australia it has highlighted the intersection of AI adoption and energy use.

The company has a 151MW power purchase agreement in Australia. It describes this as part of a broader programme of investment in energy efficiency, renewable power and low-carbon designs across its portfolio.

"At Equinix, we're making strategic investments in energy efficiency, renewable power, and low-carbon design across our global portfolio. In Australia, our 151MW power purchase agreement underscores our commitment to accelerating renewable energy adoption, complemented by local initiatives that continue to drive down our PUE. As the Australian Government advances its National AI Strategy, it's critical that sustainability is embedded as a core criterion in the process. We believe this latest assessment provides strong external validation that Equinix is delivering the transparency, innovation, and long-term investment required to help customers meet their climate commitments, while enabling technological progress and fueling economic growth," said Guy Danskine, Managing Director of Equinix Australia.

IDC says its MarketScape framework gives technology buyers a structured view of suppliers' strengths and weaknesses in sustainability. It expects further iterations of the assessment as data centre operators expand their infrastructure for AI and high-density computing.
