A federal law is already in effect. It came into force in 2025. It carries a compliance deadline of 30 May 2026. And the majority of businesses operating in the UAE have not taken a single step toward meeting it.

Federal Decree-Law No. 11 of 2024 on the Reduction of Climate Change Effects requires entities above the reporting threshold to register with MOCCAE and submit a verified greenhouse gas inventory. That is the legal obligation.

But there is a second pressure that does not care about legal thresholds. And it is arriving faster.

The Commercial Pressure Is Arriving Before the Regulatory One

Banks, tier-one clients, and multinationals operating across the GCC are already asking their suppliers for emissions data. Not because the law requires it of the supplier. Because it is required of them.

A logistics company supplying a listed corporate sits inside that client's Scope 3 emissions. A manufacturer selling into a multinational supply chain has the same problem. The client's ESG reporting commitments require data from the supply chain. That data has to come from somewhere.

The question for UAE businesses is no longer whether a GHG inventory is needed. It is whether they will have one ready when the request arrives, or whether they will be scrambling to produce one after it does.

What a GHG Inventory Actually Involves

A GHG inventory is not a sustainability report. It is not a policy document or a pledge. It is a quantified account of the greenhouse gas emissions from a defined set of operations, over a defined period, calculated using verified emission factors and documented to a standard that can withstand third-party scrutiny.

The methodology follows ISO 14064-1:2018, specifying how organisational boundaries are set, how emission sources are categorised across Scope 1, 2 and 3, and how activity data is converted into CO2 equivalent figures.

The inputs are records most businesses already hold. Fuel consumption logs. Electricity invoices. Process data. Travel records. The challenge is not that the data does not exist. The challenge is that nobody has been asked to consolidate it in a structured format before.

Where Most Businesses Are Stalling

Three problems repeat consistently among companies going through this process for the first time.

The data is fragmented. Fuel records sit with maintenance. Electricity data is in finance. Refrigerant logs, if they exist, are filed with the HVAC contractor. No single person has visibility across all of it.

The methodology is technical. Selecting the correct emission factors, setting organisational boundaries under ISO 14064-1, and categorising sources correctly require training. Getting them wrong does not just produce an inaccurate number. It produces an indefensible one when a regulator or verifier asks questions.

The timeline is being underestimated. A first-time GHG inventory typically takes four to six weeks when the client is responsive and data is accessible. For entities requiring third-party verification, add at least another four weeks.

What Genuine Preparedness Looks Like

A business that is genuinely ready has three things in place.

A completed GHG inventory for at least one reporting year, calculated to ISO 14064-1 standard, with documented emission factors and data sources that can be presented to a regulator, a client, or a verifier.

An internal understanding of how the numbers were produced, so the same process can be repeated annually without starting from scratch.

A named person or function that owns the data collection process and can respond to external requests without a months-long delay.

The Window

Companies that act now are on the right side of two conversations. The regulatory one and the commercial one.

Companies that wait will face a different situation. Data gaps that cannot be reconstructed. Clients who have moved to suppliers that could provide the information. Regulators asking about years for which no records exist.

The law has set the obligation. The market is enforcing it earlier than the law requires.

Sustainacert runs GHG inventory engagements and practitioner training for businesses in the UAE. The next training session runs on 11 April and the final session before 30 May runs on 6 May.
