The carbon you can't see: Why embodied carbon is MENA's net zero blind spot

A building can be "net zero" and still be a carbon problem.

Imagine you have just completed a landmark office tower in Dubai. A triple-glazed façade, rooftop PV array, and a building management system sophisticated enough to impress a data centre operator. The energy model performs. The certificate is framed.

And yet, before a single employee walks through the door, that building has already emitted thousands of tonnes of CO₂. From the cement plant in Fujairah to the steel mill, the trucks, the cranes, and the diesel-powered concrete pumps running for 18 months.

That is embodied carbon. And it does not appear on any energy bill.

The industry has spent decades pursuing operational efficiency, and rightly so. But as grids decarbonise and buildings become more efficient, embodied carbon is accounting for an ever larger share of total emissions. At this point, ignoring it is not an oversight. It is a choice.

What is embodied carbon and why does it hide so well?

Embodied carbon is every emission generated to bring a building into existence and, eventually, to take it apart. From mining aggregates and manufacturing cement clinkers to rolling structural steel and shipping curtain wall systems from overseas, every stage carries a carbon cost. Yet, none of it appears on a sustainability dashboard after handover.

The lifecycle stages nobody talks about

The World Green Building Council's Bringing Embodied Carbon Upfront report found that measuring and reporting embodied carbon remains the exception across the global construction sector. In MENA, the gap is even wider.

The reason it hides is simple: it's a one-time emission with no ongoing meter. By the time a client moves in, that carbon is already in the atmosphere, which makes it easy to deprioritise and nearly impossible to recover. 

MENA is building at a scale the world hasn't seen 

There's a climate-specific layer here that is rarely acknowledged. High solar gain calls for reduced window-to-wall ratios rather than expansive glazing. Where glazed façades are specified, they require high-performance systems with smart shading strategies, often resulting in aluminum-intensive assemblies with substantial embodied carbon. In parts of KSA, seismic considerations can also drive more concrete-intensive design solutions. The same desert context that makes buildings harder to operate efficiently can also make them more carbon-intensive to construct. That tension needs to be designed around, not simply absorbed.

So, what does getting it right actually look like?

Measure early: the design stage is where the game is won or lost

Running a whole life carbon assessment at the detailed design stage is like checking your speed after you've already missed the turn. The lever is early. Which means the conversation has to happen early.

How Cundall approaches it

At Cundall, we integrate whole life carbon assessments from concept and feasibility stages. That means being embedded in the design process while the brief is still being defined, not arriving after key decisions have already been made. We model carbon across structural and envelope options using industry-standard lifecycle assessment tools, and in a region where no published benchmarks yet exist, the projects we deliver today are helping to establish that baseline. The output is not a report filed at the end. It is a live input into design decisions, a carbon cost comparison that sits alongside programme and budget conversations from day one.

A developer can see, in real terms, what choosing a flat plate concrete structure over a post-tensioned system means in carbon. That is the kind of insight that changes decisions. And it is only valuable if it arrives before those decisions are made.

Small material decisions, big carbon consequences

That same principle applies to material specification. None of these choices are exotic. They are already available across the MENA market. They simply require the right questions to be asked at the right stage.

The window is open, but not forever

The EU's Corporate Sustainability Reporting Directive is already forcing global developers to account for Scope 3 emissions, which includes embodied carbon across asset portfolios. International lenders are increasingly requesting whole life carbon data as part of project due diligence. The London Plan 2021 now mandates whole life carbon assessments for all major developments under Policy SI 2.

MENA is not there yet. But the developers, consultants, and engineers building this capability now will not be scrambling when it arrives. More importantly, they will have something far more valuable: real data. Benchmarks, baselines and reduction case studies that cannot be replicated overnight.

Let's talk whole life carbon

If embodied carbon has not come up on your current project yet, it should. The earlier the conversation starts, the more influence your team has.

We work with developers and design teams across the region to carry out whole life carbon assessments from the earliest stages, before specifications are locked and while decisions still have the greatest impact.
