In 2024, Google claimed that their data centers are 1.5x extra vitality environment friendly than trade common. In 2025, Microsoft committed billions to nuclear power for AI workloads. The information heart trade tracks energy utilization effectiveness to 3 decimal locations and optimizes water utilization depth with machine precision. We report direct emissions and vitality emissions with non secular fervor.
These are laudable advances, however these metrics account for under 30 p.c of complete emissions from the IT sector. Nearly all of the emissions should not instantly from information facilities or the vitality they use, however from the end-user gadgets that truly entry the information facilities, emissions on account of manufacturing the {hardware}, and software inefficiencies. We’re frantically optimizing lower than a 3rd of the IT sector’s environmental affect, whereas the majority of the issue goes unmeasured.
Incomplete regulatory frameworks are a part of the issue. In Europe, the Company Sustainability Reporting Directive (CSRD) now requires 11,700 firms to report emissions utilizing these incomplete frameworks. The following section of the directive, overlaying 40,000+ extra firms, was initially scheduled for 2026 (however is probably going delayed to 2028). Within the United States, the requirements physique answerable for IT sustainability metrics (ISO/IEC JTC 1/SC 39) is conducting energetic revision of its requirements via 2026, with a key plenary assembly in Could 2026.
The time to behave is now. If we don’t repair the measurement frameworks, we threat locking in incomplete data collection and optimizing a fraction of what issues for the subsequent 5 to 10 years, earlier than the subsequent main requirements revision.
The restricted metrics
Stroll into any trendy information heart and also you’ll see sustainability instrumentation all over the place. Energy utilization effectivity (PUE) screens observe each watt. Water utilization effectivity (WUE) methods measure water consumption right down to the gallon. Subtle monitoring captures the whole lot from server utilization to cooling effectivity to renewable energy percentages.
However right here’s what these measurements miss: Finish-user gadgets globally emit 1.5 to 2 occasions extra carbon than all information facilities mixed, in keeping with McKinsey’s 2022 report. The smartphones, laptops, and tablets we use to entry these ultra-efficient information facilities are the larger downside.
Information heart operations, as measured by energy utilization effectivity, account for under 24 p.c of the full emissions.
On the conservative finish of the vary from McKinsey’s report, gadgets emit 1.5 occasions as a lot as information facilities. That signifies that information facilities make up 40 p.c of complete IT emissions, whereas gadgets make up 60 p.c.
On high of that, roughly 75 percent of gadget emissions happen not throughout use, however throughout manufacturing—that is so-called embodied carbon. For information facilities, solely 40 p.c is embodied carbon, and 60 percent comes from operations (as measured by PUE).
Placing this collectively, information heart operations, as measured by PUE, account for under 24 p.c of the full emissions. Information heart embodied carbon is 16 p.c, gadget embodied carbon is 45 p.c, and gadget operation is 15 p.c.
Below the EU’s present CSRD framework, firms should report their emissions in three classes: direct emissions from owned sources, oblique emissions from bought vitality, and a 3rd class for the whole lot else.
This “the whole lot else” class does embody gadget emissions and embodied carbon. Nevertheless, these emissions are reported as combination totals damaged down by accounting class—Capital Items, Bought Items and Providers, Use of Bought Merchandise—however not by product kind. How a lot comes from end-user gadgets versus datacenter infrastructure, or worker laptops versus community gear, stays murky, and subsequently, unoptimized.
Embodied carbon and {hardware} reuse
Manufacturing a single smartphone generates roughly 50 kg CO2 equal (CO2e). For a laptop computer, it’s 200 kg CO2e. With 1 billion smartphones changed yearly, that’s 50 million tonnes of CO2e per 12 months simply from smartphone manufacturing, earlier than anybody even turns them on. On common, smartphones are changed each 2 years, laptops each 3 to 4 years, and printers each 5 years. Information heart servers are changed roughly each 5 years.
Extending smartphone lifecycles to three years as an alternative of two would cut back annual manufacturing emissions by 33 p.c. At scale, this dwarfs information heart optimization features.
There are packages geared in direction of reusing outdated elements which might be nonetheless useful and integrating them into new servers. GreenSKUs and comparable initiatives present 8 p.c reductions in embodied carbon are achievable. However these stay pilot packages, not systematic approaches. And critically, they’re measured solely in information heart context, not throughout the complete IT stack.
Think about applying the identical round financial system rules to gadgets. With over 2 billion laptops in existence globally and 2-3-year substitute cycles, even modest lifespan extensions create large emission reductions. Extending smartphone lifecycles to three years as an alternative of two would cut back annual manufacturing emissions by 33 p.c. At scale, this dwarfs information heart optimization features.
But information heart reuse will get measured, reported, and optimized. Gadget reuse doesn’t, as a result of the frameworks don’t require it.
The invisible position of software program
Main load balancer infrastructure throughout IBM Cloud, I see how software architecture choices ripple via vitality consumption. Inefficient code doesn’t simply sluggish issues down—it drives up each information heart energy consumption and gadget battery drain.
For instance, College of Waterloo researchers showed that they’ll cut back 30 p.c of vitality use in information facilities by altering simply 30 strains of code. From my perspective, this outcome just isn’t an anomaly—it’s typical. Dangerous software program structure forces pointless information transfers, redundant computations, and extreme useful resource use. However in contrast to information heart effectivity, there’s no generally accepted metric for software program effectivity.
This issues extra now than ever. With AI workloads driving large information heart enlargement—projected to devour 6.7-12 p.c of complete U.S. electrical energy by 2028, according to Lawrence Berkeley Nationwide Laboratory—software program effectivity turns into crucial.
What wants to alter
The answer isn’t to cease measuring information heart effectivity. It’s to measure gadget sustainability with the identical rigor. Particularly, requirements our bodies (significantly ISO/IEC JTC 1/SC 39 WG4: Holistic Sustainability Metrics) ought to lengthen frameworks to incorporate gadget lifecycle monitoring, software program effectivity metrics, and {hardware} reuse requirements.
To trace gadget lifecycles, we want standardized reporting of gadget embodied carbon, damaged out individually by gadget. One combination quantity in an “the whole lot else” class is inadequate. We want particular gadget classes with manufacturing emissions and substitute cycles seen.
To incorporate software program effectivity, I advocate creating a PUE-equivalent for software program, resembling vitality per transaction, per API name, or per consumer session. This must be a reportable metric below sustainability frameworks so firms can display software program optimization features.
To encourage {hardware} reuse, we have to systematize reuse metrics throughout the complete IT stack—servers and gadgets. This consists of monitoring restore charges, creating large-scale refurbishment packages, and monitoring part reuse with the identical element presently utilized to information heart {hardware}.
To place all of it collectively, we want a unified IT emission-tracking dashboard. CSRD reporting ought to present gadget embodied carbon alongside information heart operational emissions, making the complete IT sustainability image seen at a look.
These aren’t radical adjustments—they’re extensions of measurement rules already confirmed in information heart context. Step one is acknowledging what we’re not measuring. The second is constructing the frameworks to measure it. And the third is demanding that firms report the whole image—information facilities and gadgets, servers and smartphones, infrastructure and software program.
As a result of you’ll be able to’t repair what you’ll be able to’t see. And proper now, we’re not seeing 70 p.c of the issue.
