The Cloud Has Weight: My Feature in Blooming Sustainability Edition 58

Published on Sustainably Digital | April 10, 2026

I'm proud to share that I was recently featured in Edition 58 of the Blooming Sustainability series, curated by the award-winning team at &BLOOM Sustainability & ESG. It's a platform that brings together thought leaders across Aotearoa New Zealand, Australia and beyond who are doing genuine work at the frontier of sustainability — and being included in that conversation means a great deal.

But rather than simply sharing the link and moving on, I want to use this post to pull out the threads that matter most — the ideas I believe every sustainability, technology, and finance professional needs to be sitting with right now.

The Uncomfortable Truth We Keep Avoiding

Let me start where the feature starts: the cloud is not weightless.

That might sound obvious when stated plainly. But the language we use — the cloud, virtual, serverless — is doing serious damage to our collective ability to account for digital emissions. These euphemisms allow organisations to mentally decouple their digital operations from physical reality. And physical reality is this: behind every video stream, every database query, every AI inference sits a server drawing power, a cooling system running continuously, and cables connecting it all together.

“Naming that reality is where accountability begins.”

This is the foundation of everything I do at Sustainably Digital. You cannot manage what you don't measure — and right now, most organisations aren't measuring their digital footprint with anything close to the accuracy that strategic decision-making demands.

Why Your Current Measurement Approach Is Probably Wrong

Here's the method most organisations use to calculate their technology-related carbon emissions: take IT spend, multiply by an average emission factor, record the number, move on.

It's fast. It's simple. And it is materially inaccurate.

Spend-based estimation masks the true scale of digital emissions. It flattens the enormous variation between workloads, data centres, cloud providers, hardware generations, and grid carbon intensities into a single blunt number. It gives organisations false confidence that they understand their footprint when, in reality, they're looking at a rough sketch where they need a detailed blueprint.

The alternative — activity-based measurement — tracks actual consumption at the workload level. It demands granular, vendor-supplied emissions data. It produces a baseline that organisations can actually act on.

The challenge? That data largely doesn't exist, or vendors won't share it. This is what I call the Scope 3 black box — the wall of opacity that technology suppliers routinely hide behind, and one of the most significant systemic barriers in digital sustainability today.

This must change. And increasingly, it will — because of a force more powerful than regulation or net-zero ambition alone.

The Force That Changes Everything: Procurement

A UK study tour was a turning point in my thinking on this. Sitting alongside leading climate scientists and digital sustainability practitioners from across the world, one signal was unmistakable: buyers are beginning to demand emissions transparency from their technology suppliers.

This is not a distant trend. It is arriving now. Organisations that cannot provide granular, credible emissions data for their products and services will find themselves disadvantaged in procurement processes — losing contracts not because their product is inferior, but because their sustainability reporting is.

For technology vendors, this is a wake-up call. For sustainability and procurement teams, this is your emerging source of leverage.

Speaking the Language of the CFO

One of the questions I'm asked most often is: how do you get leadership to care about digital sustainability?

My answer is consistent: lead with ROI, not compliance.

My favourite example is zombie servers — idle or underutilised cloud resources that sit running around the clock, consuming energy and generating costs, delivering nothing. Most organisations have them. Many organisations have a lot of them.

Identifying and decommissioning zombie servers does something remarkable: it reduces operating costs and carbon emissions simultaneously, with zero trade-off. No business case friction. No competing priorities. Just waste eliminated on two dimensions at once.

That's the story that lands in a CFO conversation. That's the entry point into a broader discussion about digital efficiency as a sustainability lever.

My conviction — and it's one that has only deepened over the years — is that sustainability and operational efficiency are not in tension. They are the same conversation. When sustainability professionals can walk into a boardroom and speak the language of resilience, cost reduction, and enterprise value, the dynamic shifts entirely.

Aotearoa's Underutilised Superpower

If there's one thing I want New Zealand's technology and business community to fully grasp, it's this: we have a genuine competitive advantage, and we are not claiming it deliberately enough.

Aotearoa's energy grid — powered by a leading mix of hydro, geothermal, and wind — gives our cloud environments an APAC-leading 'B' rating for grid carbon intensity. Against a backdrop of fossil-fuel-dependent grids across much of Asia-Pacific, including Australia, this is extraordinary.

New Zealand has the foundations to become a regional model for clean cloud infrastructure. That's not aspiration — it's a structural reality waiting to be leveraged. As global buyers increasingly factor emissions data into procurement decisions, the carbon intensity of where data is processed and stored will matter commercially in ways it hasn't before.

We should be far more deliberate about building and promoting that identity.

The Seed I Most Want to Plant

If my work could leave one lasting change, it would be this: sustainability as a design constraint, not an afterthought.

Right now, most organisations encounter sustainability considerations downstream — retrofitting efficiency onto systems that were never designed for it, right-sizing infrastructure that was over-provisioned from the start, cleaning up technical debt that carries both financial and environmental cost.

I want to see energy efficiency, hardware circularity, and workload right-sizing built into the brief before a single line of code is written or a server is provisioned. The most sustainable system is the one you design well from the start.

This requires IT architects, sustainability leads, and finance teams to be in the room together — early. Which brings me to perhaps the most important structural challenge in this space.

The Coalition We Need to Build

Sustainability practitioners are doing exceptional work defining ESG strategies and science-based targets. But execution lives in technical architecture — and that's an IT conversation.

With 77% of Chief Sustainability Officers citing integrated data systems as their top unmet need, and the digital sector responsible for an estimated 2–4% of global emissions, we cannot afford to keep these communities working in parallel.

We urgently need to mobilise the 1.2+ million ICT professionals across Aotearoa and Australia as active co-leads in our sustainability transition — not bystanders, not downstream implementers, but genuine partners in shaping the strategy from the outset.

That mobilisation is one of the core missions of Sustainably Digital.

One Action You Can Take Today

If you've read this far and want somewhere concrete to start, here it is:

Audit your digital dead weight — today.

Open your cloud billing dashboard. Look for resources with near-zero utilisation. Turn them off. You don't need a sustainability strategy, a consultant, or a board mandate to do this. You need fifteen minutes and a login.

You'll cut costs and carbon simultaneously — and you'll have your first data point toward a technology emissions baseline. That's how a journey of a thousand miles begins.

A Genuine Thank You to &BLOOM

I want to close by acknowledging Sydney Straver and the entire &BLOOM team. The Blooming Sustainability series creates something genuinely rare: a space where thought leadership meets practical action, and where the voices shaping Aotearoa's sustainability future get to be heard properly.

If you work in ESG, responsible investment, or sustainability strategy — and you're not yet following the series — I'd encourage you to do so.
