With more data centres transitioning to renewable energy sources, Scope 3 emissions become a data centre’s largest contributor to its greenhouse gas (GHG) emissions. This category of emissions is also the least reported and understood.
The focus on quantifying Scope 3 emissions in the value chain is part of a broader effort by organisations to assess and manage their environmental impact comprehensively. However, it requires a data-driven approach to helping data centre operators identify and categorise emissions from operations and the supply chain, then prioritise efforts to make impactful carbon reductions. This includes outsourced IT services from cloud and colocation service providers.
Undertaking this process allows for more informed decision-making and targeted efforts to reduce carbon emissions throughout the value chain. Developing a strategy that identifies the biggest source of carbon emissions in the value chain is quickly becoming a data centre industry priority, alongside the urgency to establish easy-to-use frameworks.
Data collection practices for a reporting framework
The effort to quantify and manage Scope 3 emissions aligns with broader trends in sustainability and corporate responsibility. Many organisations are recognising the importance of transparently addressing their environmental impact as part of their commitment to sustainable practices, but they don’t know where to start, which reporting framework to use, or how often they should be collecting and reporting data.
However, quantifying and reporting on Scope 3 presents a significant challenge for data centre operators. This is mainly due to a lack of three resources: reliable supplier data, quantitative tools, and an accounting and reporting methodology.
Establishing and implementing a framework that incorporates accurate carbon counting and target setting, while systematically reviewing company data and emission sources, is the foundation to creating an achievable reduction plan.
Electricity generation, GHG emissions and water consumption determine the carbon and water footprint of data centres, including that of its suppliers. To be successful, suppliers must provide data centre operators with their own Scope 3 emissions data, related to the products used in their data centres.
These emissions vary significantly depending on many factors including data centre size, redundancy level, location, electricity emission factor, core and shell construction, IT equipment configuration, energy efficiency, equipment lifespan and replacement frequency, and value chain activities.
Sustainability reporting can provide a competitive advantage
The proactive stance of data centre operators towards achieving net-zero climate goals reflects a broader shift in business attitudes toward sustainability. As environmental concerns become more prominent, companies are recognising the need to align their operations across the value chain with climate goals to meet the expectations of a diverse range of stakeholders including customers, investors and vendors, and contribute to a more sustainable future.
Aside from being a compliance necessity, GHG reporting encompassing Scope 3 emissions is increasingly being recognised as a strategic and beneficial practice for the data centre industry. It aligns with the growing emphasis on sustainability, helps manage risks, and positions companies as responsible and forward-thinking entities in an environmentally conscious market.
Robust emissions reporting can enhance investor confidence and attract investment from those seeking sustainable and responsible opportunities. Data centres that prioritise emissions reduction and extend their sustainability efforts to their supply chains can provide a competitive edge. A resilient and sustainable supply chain can contribute to business continuity and enhance the overall reputation of a company.
Vendor commitment to reducing embodied carbon
Scope 3 emissions are by far the most challenging to report for data centre operators who should integrate sustainability into their evaluation criteria when selecting data centre equipment suppliers and service providers to minimise Scope 3 value chain carbon footprint.
Vendors need to commit to reducing the embodied carbon of their product portfolio. Finally, data centre equipment suppliers must make environmental product disclosure documents freely available and easily understandable for their products.
By actively seeking equipment suppliers and service providers committed to reducing their environmental impact, data centre operators can play a crucial role in mitigating the overall carbon footprint associated with their operations related to Scope 3 emissions. The call for transparency and the availability of environmental product information further enhances the ability to make sustainable choices in the selection of data centre equipment.
Many organisations have focused on measuring and reporting Scope 1 and 2 emissions associated with their IT resources and implementing strategies to reduce them. Knowing where to start on your Scope 3 emissions metrics journey can be daunting. By quantifying Scope 3 emissions from their value chain, organisations can measure their total carbon footprint, including outsourced IT services from cloud and colocation service providers. Organisations can then prioritise their efforts to make impactful carbon reductions.
Schneider Electric offers many resources and tools to help organisations define Scope 3 emissions, including an inventory of nine emissions source categories and their data centre-specific subcategories for accounting and reporting purposes. This includes a modelling tool to simulate and model energy consumption within data centres that can help to estimate associated CO2 emissions. It also considers other factors such as power consumption, cooling systems, and overall data centre efficiency.
Its supply chain decarbonisation services help users leverage technology to measure and model resource use in the supply chain, educate and engage supplier partners, and support actions to decarbonise supplier operations.
By following these initial steps, data centres can expand their understanding of Scope 3 emissions and implement the right tools and measurement practices to work towards reducing their overall environmental impact and meeting reporting requirements with improving results.

Decisions that go into designing a new data centre will stay in place for many years to come. For instance, the cooling solutions often determine how the facility will consume vital resources such as water and energy. Equinix is committed to using water responsibly, which means we include several considerations about the local water context as we design our data centres.
Last year, we were designing a new data centre in an area where the public had concerns about water stress. The facility was originally intended to use evaporative cooling, which relies on evaporating water to cool the building. The benefit of this approach is that it is substantially more energy efficient than cooling systems that don’t use water.
We conducted an in-depth water stress analysis to gain a more comprehensive understanding of the local water context. This analysis included assessing physical water availability, infrastructure and local resiliency planning to understand how prepared the metro was in case of increased water stress.
Although the metro was well prepared for a drought or other increases in water stress, we decided to switch the building cooling system to use air cooling. Since air cooling consumes substantially less water, we proactively aligned with local concerns about water stress, which reflects our commitment to minimising our impact. However, air cooling also consumes more energy, which is why it isn’t right for every location.
When it comes to balancing the trade-offs between water and energy consumption, getting it right during the design phase is essential, as there are only opportunities for incremental water efficiency improvements after a data centre is operational.
What is water stress?
According to the Pacific Institute, a leading research institute focused on water issues, water scarcity refers only to volumetric availability: the ratio of human water consumption to available water supply in an area. In contrast, water stress is a broader, more inclusive concept. Water scarcity is one aspect of water stress, but it also includes other physical factors, such as water quality and environmental flows, and economic factors such as water accessibility.
Understanding the local water context, including water stress levels, is the foundation of our approach to using water responsibly. In 2023, we codified our commitment to avoid using evaporative cooling in areas with high water stress because using evaporative cooling is by far the largest driver of water consumption in data centres.
How does data centre cooling impact water consumption?
IT equipment running in data centres creates heat, and that heat has to go somewhere. Choosing a cooling solution will determine how a facility consumes water and energy, which are both essential aspects of any data centre operator’s sustainability strategy. However, cooling systems are needed at both the server level and the building level. As servers generate heat, the server-level cooling system moves the heat away from the servers to a heat exchanger, which transfers the heat to the building-level system. The building-level system then rejects the heat from the building.
There are different options for both server-level cooling and building-level cooling:
At the server level, air cooling has long been the standard practice, but liquid cooling is becoming more prevalent to support higher server density for AI and other compute-intensive workloads. One misconception about liquid cooling is that it’s the same as evaporative cooling. However, unlike evaporative cooling, liquid cooling doesn’t necessarily increase water consumption because it uses a small amount of water moving continuously in a closed loop, rather than being evaporated.
At the building level, the two primary methods for rejecting heat from a data centre are air cooling (or dry cooling) and evaporative cooling. Evaporative cooling can reject the same amount of heat as air cooling while consuming significantly less energy. However, it also consumes significantly more water via evaporation.
Data centre designers typically choose between air cooling and evaporative cooling based on the unique climate conditions of each specific location. To determine the most suitable system they’ll consider the local climate (weather), power availability, water stress and other factors. For instance, evaporative cooling can be particularly effective in managing energy usage in areas with power-constrained grids. In contrast, avoiding evaporative cooling in water-stressed areas minimises water consumption, thus ensuring more water remains available for use in the community.
Balancing this trade-off is at the core of our responsible water strategy. In 2023, we use evaporative cooling at only 40% of our data centres globally. We also take advantage of alternative cooling methods where local conditions allow:
Geothermal cooling methods such as aquifer thermal energy storage (ATES) and deep lake water cooling (DLWC) utilise natural cooling provided by the Earth’s thermal mass. They draw cold water from large natural sources to circulate through the building-level cooling system, thus causing the water to absorb heat from the heat exchanger. Rather than rejecting it into the atmosphere via evaporating the water, geothermal cooling returns water to its original source. Therefore, the process doesn’t consume water. Similarly, one of our data centres in Toronto uses a DLWC system that pulls cold water from the depths of Lake Ontario. With this approach, we’ve reduced total energy needs for this data centre by 50%, without increasing water consumption.
Data centre heat export allows a portion of the heat in a data centre to be transferred to a third-party heat network rather than being rejected into the atmosphere. The heat can then be used for heating homes and businesses. This not only avoids unnecessary water consumption in other buildings’ cooling systems, but also provides a low-carbon heat source for communities. Equinix is pursuing heat export in select locations worldwide. In Paris, heat recovered from our PA10 data centre is transferred to the Plaine Saulnier urban development zone, including a swimming pool used at the recent Paris Summer Olympics.
Improving transparency around water consumption
Recognising that many of our stakeholders want to know more about how we use water and how we’re working to use it more responsibly, we’ve taken steps to increase transparency on our water use.
In 2023, for the first time, we disclosed our water metrics via the CDP water security initiative and included water metrics in our annual sustainability report.
In addition to our water optimisation efforts, our operations team is developing and implementing water efficiency best practices and improving our water metering systems at all existing data centres that use evaporative cooling.
Externally, we are collaborating with our peers and industry working groups to develop measurement frameworks and standards to support water reporting efforts. Earlier this year, we joined the California Water Action Collaborative, a network of diverse stakeholders pursuing collective action projects that improve water security in Equinix’s home state.
We’re also co-funding our first offsite nature project in Finland with Neoen, our local renewable energy partner, to restore 50 hectares of high-value peatland and streams. Since offsite projects like this one often provide both water and biodiversity benefits, we’re sponsoring the development of a framework to account for biodiversity benefits along with water benefits from these kinds of projects.

Businesses are being encouraged to prepare for the impact of mandatory climate disclosure in Australia.
Earlier this year, the federal government passed amendments to the Corporations Act 2001 (Cth) and the Australian Securities and Investments Commission Act 2001 (Cth), resulting in mandatory climate reporting for larger businesses in Australia.
The issue was examined during a recent address to members of the Underwriting Agencies Council, with particular attention paid to how the new legislation will affect the insurance sector.
Speaking at the event, Prateek Vijayvergia, Xceedance Business Leader – Key Accounts, Australia and New Zealand, said that while 75% of ASX 200 companies were committed to or already performing climate reporting, the number fell to 10.5% for broader ASX companies.
“There’s a lot more awareness and commitment and urgency that we see in the Australian market now and this is not limited only to the insurance business, but for all larger Australian businesses,” he said.
“Although this is all good, there is a gap in climate-related reporting among ASX-listed entities, and the depth and the quantification.”
Joining Vijayvergia in the discussion was Sharanjit Paddam, Principal – Climate Analytics at Finity Consulting, who said that from 31 December 2025, in addition to an Annual Report, large companies will need to submit a Sustainability Report — what Paddam referred to as “the home for ESG disclosures”.
Four pillars underpin the disclosure standards — governance, strategy, risk management, and metrics and targets. Paddam emphasised that the devil is in the detail.
“You not only have to disclose the financial impacts on your balance sheet today and your income statement today, but also in the short-, medium- and long-term future,” he said.
“They (ASIC and APRA) want hard numbers to be put in the accounts about how climate change is financially going to affect the operations of the company.”
Paddam explained: “At the heart of the disclosure is really what are the financial impacts of climate change on your company, investors, customers and shareholders; to understand that and to allocate capital and make investment decisions informed by how climate change might affect your business.”
Paddam added that companies need to consider their own impact on climate change.
“The world is changing in disclosures in a very big way over the next few years, and companies are going to have to think about not just accounting for their financial outcomes, but also their climate outcomes,” he said.
“These are mandatory standards — this is locked in, and it will be required to happen over the next few years, and it is intended that these standards will change the economy and they will drive changes throughout the way we do business.”
A particular challenge will be the reporting of Scope 3 emissions — those indirectly generated by the activities of an organisation — due to lack of data, methodology and resources.
“What’s really helping all of us is the advancement in technology so there are better ways of collecting information and data around emissions,” Vijayvergia said.
“And also, to then slice and dice that information so it can be used to make a plan around climate risk.
“It’s becoming more comprehensive and almost integral to the overall reporting that’s happening for an organisation.”
Organisations impacted by these legislative changes include those that produce accounts under the Corporations Act and meet any two of the following criteria: consolidated assets more than $25m; consolidated revenue more than $50m; or 100 or more employees.
Paddam said the new requirements would capture some of the larger underwriting agencies and brokers.
“It’s an opportunity to look at the services that you are providing and how good a partner you are for your insurance provider, or as a distributor of insurance products, to see where you could uplift your services in this respect,” he advised.
“The things we insure, the things we invest in, are all intended to change as a result of these disclosures, and getting your heads around that quicker and faster than your competition is very important.”
