IT Sustainability Think Tank: How IT sustainability entered the mandate era during 2025 | Computer Weekly
As the calendar turns the final pages on 2025, the information technology sector stands at a critical juncture regarding its environmental commitments. This year was not marked by technological breakthroughs solving decarbonisation, but by the decisive maturation of sustainability from a strategic differentiator into an operational and regulatory imperative.
This transition involved a painful reckoning with data complexity, supply chain reality, and the sheer energy appetite of modern computing, driven primarily by the rapid proliferation of artificial intelligence (AI).
We entered 2025 with goals framed by aspiration; we exit under the binding mandate of actuality. The central shift is profound: IT sustainability is no longer a parallel environmental, social and governance (ESG) initiative.
It has become deeply intertwined with core business continuity, geopolitical supply chain risk, and mandatory financial disclosure. While this shift signals progress, momentum is driven more by necessity and the threat of liability than by shared ethical commitment.
The conversation evolves from aspirational to accountable
The most profound shift over the past year has been the forced elevation of the sustainability dialogue directly onto the executive committee’s core risk portfolio. This movement is not voluntary; it is driven by impending regulation and the sobering realisation that environmental failure now carries direct, auditable financial penalties and board-level liability.
Only a year ago, discussions circled around unquantifiable reputational benefits. Today, the lexicon is dominated by acronyms signalling mandatory compliance: CSDDD, CSRD, and the tightening of the SBTi Net-Zero Standard V2. These frameworks compel executives to move past narratives and confront the granular, auditable data attached to every asset, vendor, and cloud usage.
For the CIO, this manifests in two critical areas. First, energy efficiency is decisively reframed as a cost of doing business, crucial for operational expenditure control amid volatile global energy markets. Second, the sudden energy demand of generative AI has triggered a rapid, internal debate on responsible compute architecture.
Leaders are increasingly compelled to justify AI investment not solely on traditional ROI, but via a nascent “return on compute” model that necessarily integrates and accounts for carbon expenditure. This makes the environmental cost of IT an integrated input in the total cost of ownership calculation, rather than a polite footnote.
Despite this high-level engagement, progress remains complicated. The IT function often lacks the authority to enforce change across complex internal silos, and the necessary budget and risk tolerance for truly transformative shifts remain stubbornly limited.
Genuine progress where the green shoots are taking hold
Despite systemic inertia, 2025 delivered solid, tangible progress in certain operational domains, offering a partial blueprint for future net-zero efforts. Our confidence is bolstered by three examples, though it is crucial to understand that wide-scale adoption across the average enterprise remains nascent and often confined to pilot programs:
1. Decoupling cloud growth from carbon: Hyperscale cloud providers have largely won the battle for renewable energy procurement. The next frontier — optimising physical operations — has seen enterprise engagement. We saw accelerated adoption of advanced liquid cooling technologies (still primarily concentrated in hyperscale environments, but critical for future AI scaling). Enterprises optimising workloads for low-carbon regions and utilising serverless architectures successfully decoupled rapid cloud expansion from a proportional rise in emissions. This success belongs predominantly to the hyperscalers, and enterprise optimisation remains an ongoing campaign.
2. Maturing the circular IT model (As-a-Service): The year 2025 saw the Managed Device-as-a-Service (MDaaS) model transition into a critical environmental enabler. By outsourcing the entire device lifecycle, enterprises commit practically to refurbishment and robust reverse logistics. Successful enterprises leverage these contracts to guarantee asset re-entry into the value chain via certified refurbishment, drastically reducing e-waste. The caveats are two-fold: MDaaS adoption is far from universal, and the verification of these circular chains still lacks necessary, robust third-party scrutiny.
3. The nascent rise of green software engineering: The formal emergence of green software engineering (GSE) is perhaps the most encouraging development. For too long, the environmental focus was only on hardware. This year, organisations began measuring code energy consumption — optimising algorithms and refactoring applications to reduce reliance on resource-intensive computing.
An important development this year was the publication of the W3C Web Sustainability Guidelines (WSG) Draft Note. Developed through a global, collaborative effort — in which I was pleased to participate — the guidelines offer a structured and internationally relevant set of best practices for reducing the environmental footprint of web products and services. While the scope focuses specifically on the web rather than the full breadth of enterprise IT, the Draft Note nonetheless represents a significant step forward for the industry.
The persistent gaps undermining net-zero momentum
For all the genuine acceleration, 2025 was equally defined by two persistent, critical gaps that threaten to derail net-zero pathways and demand urgent attention.
1. The Scope 3 emissions chasm: The most pervasive and frustrating gap remains the measurement and meaningful reduction of Scope 3 emissions, particularly from purchased goods and downstream asset end-of-life.
Despite regulatory urgency, the vast majority of enterprises still rely on highly aggregated, industry-average supplier data (spend-based or activity-based), which is neither auditable nor sufficient for mandatory disclosure. The necessary mechanism — detailed, granular product carbon footprints (PCF) provided by every vendor — is simply not available at scale or with sufficient fidelity.
The problem persists because it requires collaboration across complex, often proprietary global supply chains. Suppliers are reticent to disclose granular data, citing competitive concerns, while buyers lack the leverage to mandate it. The result is a ‘Scope 3 plateau’: targets are set, but underlying emissions remain stubbornly high, creating a significant credibility risk. We are still largely measuring a reflection, not the reality.
2. The generative AI energy debt: While AI is a powerful tool for sustainability optimisation, the immediate, unmanaged energy demand of Large Language Models (LLMs) represents a profound and growing gap. The speed of AI adoption, combined with the inherently expensive High-Performance Computing (HPC) required, creates an “energy debt” that offsets hard-won gains elsewhere.
The challenge is governance. Enterprises are deploying AI solutions without robust, mandatory policies on model selection, inference efficiency, or resource decommissioning. Crucially, most organisations remain focused on achieving initial ROI metrics, relegating energy efficiency to an optional performance tweak. Failure to enforce a framework for ‘responsible compute’ risks the transformative power of AI being negated by its own expanding environmental impact. This is the single greatest risk to the IT sector’s net-zero journey.
Strategic priorities for 2026 and beyond
As the IT Sustainability Think Tank looks towards 2026, the focus must shift from identifying the problem to systematically closing the remaining gaps with institutional discipline. We must treat these priorities as non-negotiable elements of future business resilience:
- Mandate data granularity for Scope 3: Leverage procurement influence to force supplier compliance on verifiable Product Carbon Footprints (PCF). The mandate must be non-negotiable, enforced with clear vendor scorecards and contractual requirements.
- Institutionalise green software engineering: Invest heavily in training and tooling to embed energy efficiency into the software development lifecycle (SDLC). Software architecture must be treated with the same environmental scrutiny as data centre cooling, making efficiency an audited requirement.
- Govern the AI energy cost: Implement a Responsible AI framework that includes mandatory energy consumption metrics and resource allocation policies for all Generative AI deployments.
The year 2025 was when IT sustainability moved into the board’s audit file. Next year must be the year we finally gather the granular data, enforce the necessary discipline, and manage the rapidly growing energy appetite of our own invention. The time for aspirational statements is definitively over; the urgent task now is to move these nascent efforts into full, verifiable accountability.
You don’t need a four-figure Swiss movement to know what time it is—or look good doing it. One of the most wonderful things about “budget” watches today (although it’s kinder, or more appropriate, to say “affordable”) is that brands have learned to take design cues from luxury timepieces while quietly getting very good at the fundamentals: reliable movements, thoughtful materials, and proportions that don’t scream “cheap.” Take a look at the Orient in WIRED’s selection below as a prime example.
It could easily be argued that we’re in a golden age of affordable horology (see our full guide here for definitive proof), where, if you choose wisely, $350 or less can buy everything from a desirable dress watch, or a high-end collaboration, and even a supremely capable and classically chic diver. Pieces that will see you right from sunken wreck to boardroom table. And let’s not forget the retro allure of digital watches right now, either, with the Shark Classic not only being one of our favorites here, but at $70, it’s also the most affordable.
Moreover, should you decide to bag more than a few (and who could blame you at these prices?), we’ve even got the perfect carry case picked out: Nanuk’s IP67 waterproof and dustproof NK-7 resin $175 910 Watch Case (pictured above) with patented PowerClaw latching system—ideal for securing any timepiece collection, be it bargain or big budget.
Be sure to check out our other wearable coverage, including the Best Budget Watches Under $1,000, Best Smartwatches, Best Fitness Trackers, and Best Smart Rings.
Same as the Five Senses deck above, this scratch-off card set happens in sequence, with optional “level up” cards to really push intimacy, and separate cards for each partner with secret directions. For this date, you’ll both bring a red item that you show at certain points to signify that you’re open to physical touch. Then you’ll go out to dinner and have intentional conversation, and every time a partner pulls out the red item, you’ll follow the prompts to initiate increasingly intimate physical acts, ranging from hand holding to neck kisses. So there we were, at Illegal Taqueria, edging each other over al pastor tacos (I kid).
Many of the cards urged a partner not to interrupt or solve problems, but ask questions and talk dirty. My date said, “I think this may be for couples who hate each other.” I had to agree. The second part of the date involved driving and stoplights, but since we were in Brooklyn, we walked down the trash-filled sidewalk and pretended to be a suburban couple on the fritz instead.
The rest of the date included buying things for sexy time, like whipped cream and blindfolds. I’m vegan and had no desire to lick cream from chest hair, so we came home, stripped, and did our best to keep our eyes closed (in lieu of a blindfold). It was overall a strange experience for us both, I think. If you and your partner need a lot of prompting to connect, compliment, and be physical, this set is for you.
Date: Greg, 10/10 (Note: I didn’t find this man on Hinge; I met him the old-fashioned way, in a bar at 2 am.)
Box: 6/10
Valentine’s Day is a sneaky one. It’s easy to let grabbing fun and unique Valentine’s Day gifts fall to the wayside while you recover from the Christmas holidays, but it’s not one to miss if you have a partner you want to shower with a little extra love.

For a Gift That’s a Date
My husband and I are planning our fourth or fifth year of our favorite Valentine’s Day Date: building Lego sets together. We’ve done this for years, and then we get to enjoy the fruits (well, flowers) of our labor around the home forevermore. These sets serve as both the gift and the activity. Building the dried-flower centerpiece together was probably my all-time favorite, since you can each simultaneously work on one half and then click it together at the end, followed by each building a different-color bonsai tree.
For a Daytime Adventure
Retrospec
Weekender Crew Multi-Person Inflatable Paddle Board
Building on the idea of date activities that involve gifts, this multi-person paddleboard is a fun way to spend time outdoors while staying together the entire time. It’s massive, almost raftlike, so that it can support the weight of up to three adults, but once we got the hang of the size, it wasn’t hard to maneuver. Sometimes we’d both row together, sometimes I’d let my husband do all the work. It made for a lovely daytime adventure together, and I can’t wait for the next warm day for my husband and me to take this out on our local harbor again. It’s big enough that we could bring our son, though it’s much more peaceful as a date activity. It’s inflatable, and I’d recommend grabbing an electric filler since it takes a lot of manual pumping otherwise.
For Flowers on Demand

The classic go-to for Valentine’s Day is, of course, flowers. WIRED reviewer Boutayna Chokrane tested several flower delivery services to find the best one to get sent to your home, and her favorite is the Ode à la Rose, specifically the Edith arrangements. The business was created by two former French bankers, and the arrangements’ design choices feel distinctly chic in a way only French romance can. The Edith bouquet is entirely Columbus double tulips from Holland, and come hand-tied in a travel vase a fun pink box. The flowers ship nationwide, and there’s same-day shipping in New York, Chicago, Los Angeles, Austin, Miami, and Washington, DC.
For a Jewelry Upgrade
Maybe you’ve already exchanged rings, or maybe you’re looking for your first set without committing to I do. Either way, the most popular fitness tracker to get these days is a smart ring, and Oura is the ruler of the space. The latest model is the Ring 4, and it comes in both metallic and ceramic finishes. Many of my friends love theirs. I wish I had one, but they don’t make sense for my husband and me since we’re an aerialist and rock climber duo. Live my dreams for me and get this for your valentine (and yourself)!
For Your Fave Photographer
If your romantic partner loves to capture photos, a digital photo frame is the perfect gift (and you’ll benefit, too, as likely the number one fan of their photography!). I’m the photographer of our house, and our Aura frame is my husband’s favorite gadget because it showcases photos I’ve captured of our son and life together over the years. Our wedding photos can be found on there too, as well as the occasional good photo of me that he’s captured. It’s a monthly ritual for me to go through my camera roll and add my latest favorites. Aura’s my favorite because the range of frames is beautiful, and the storage is unlimited with no fees or subscriptions.
For the Cozy Couple
One of my favorite souvenirs I have around the house is a matching robe set that my husband and I bought on our honeymoon. Our all-cotton robes are from the Ten Thousand Waves Japanese spa in New Mexico (the final destination of a Southwestern US road trip) and are great for taking to the pool or using after a shower on a hot day. But I still love a good fluffy robe during the colder season, especially since it can double as a towel. Get your partner one of these cozy robes to give them something luxurious to use after their next everything shower or quick rinse-off. Cozy Earth’s robe is crazy-soft thanks to its blend of cotton and bamboo viscose, while this flannel robe from L.L.Bean is one of our favorites for anyone who works from home.
For Your Inner Theater Kids
If your partner loves to sing along to the Wicked soundtrack and is regularly suggesting karaoke as a group activity, then give them the gift of making karaoke happen anywhere with these gadgets. The Bonaok Karaoke Microphone is one of our favorite karaoke microphones, letting you sing anywhere without lugging bulky equipment. The Ikarao Shell S2 is a portable device with two mics, a built-in screen, and support for streaming services, so you can sing along to your favorite songs on Spotify.
For the Fitness Couple
After the Christmas season, I saw a video on my For You page that roasted how every mom had clearly gotten a matching workout outfit set for Christmas and was out wearing it on Boxing Day. As a mom myself, all I could think of was how much I would love another matching workout set. I’m serious. They’re great for workouts, quick errands, and day care or school drop-off. My latest favorite set is from Bombshell Sportswear. The set is both super soft and fits securely without any annoying squeezing. It’s getting the most compliments of all my sets. I wish I’d sized up with the bolero, but as an aerialist, my lat muscles are a little bulkier than an everyday person’s.
Have a partner who doesn’t need a matching set? Try some fantastic running shoes instead, which are even more useful for both workouts and daily life. WIRED reviewer Adrienne So says these R.A.D. shoes are fantastic for a range of uses, as they’re designed for gym, HIIT, CrossFit, and hybrid workouts and are soft enough for treadmill running. They look fantastic, too.
For the Beloved Bookworms
A Kindle is always a great gift for anyone who reads in any format. Funny enough, my siblings and I are about to buy one for my dad for his birthday (two weeks before Valentine’s Day), and I recommended my favorite pick, the Kindle Paperwhite, since the standard Kindle is a little too small for his 6-foot-4 frame to hunch down over, and he doesn’t read enough illustrated books to make the Colorsoft the right jump for him. If they already have a Kindle, I’m still in love with my matching PopSockets Kindle case and grip, and they’ve since launched a new Bookish collection with beautiful designs.
For Some Bedroom Spice
Looking to spice things up? These adventure boxes can add more fun to the bedroom without creating additional mental work for you and your partner. An offshoot from the Adventure Challenge, “The Adventure Challenge … In Bed” scratch-off date book has 50 date ideas designed specifically to help facilitate fun and connection in the bedroom. The dates are categorized by activity type in sections like food, dancing, “sexploration,” and more. Each date is covered by a black box, with only icons indicating required fields such as duration, cost, and more. Meanwhile, the Fantasy Box is a date-night box service offering a range of themes, from sexy wine tasting to a kinky poker night, all designed to help couples communicate and connect more intimately. Before opening the box, each partner will fill out a questionnaire of potential intimate acts, and this box comes with everything needed for a truly kinky night in: a satin blindfold, pleather paddle, lingerie, lube, massage gel, feather wand, mini vibrator, and silky wrist restraints. —Molly Higgins
