For a long time, corporate sustainability felt a bit like a competitive sport in creative writing. We saw the glossy brochures, the stock photos of saplings cradled in cupped hands, and the bold claims of being “eco-friendly” or “carbon neutral” by a date far enough in the future that most of the current board would be retired. It was the era of the green fairy tale: pleasant to read, light on detail, and largely free of consequence.
That era is officially coming to an end. If you are sitting in a boardroom today, the “green” conversation has shifted from the marketing department to the legal and finance offices. The UK is currently undergoing its most significant overhaul of corporate sustainability reporting since mandatory climate disclosures first arrived in 2022. Between the new UK Sustainability Reporting Standards (UK SRS), the Financial Conduct Authority (FCA) consultation CP26/5, and the Competition and Markets Authority (CMA) sharpening its teeth on greenwashing, the tension is palpable.
The question is no longer whether you are doing your bit for the planet. The question is: can you prove it to a regulator?
The 2027 deadline: From TCFD to UK SRS
If you have finally grown comfortable with the Task Force on Climate-related Financial Disclosures (TCFD), I have some news that might be slightly frustrating. The TCFD has been disbanded and is being replaced by the UK SRS, based on the global baseline set by the International Sustainability Standards Board (ISSB).
On 25 February 2026, the Department for Business and Trade published the finalised UK SRS. While currently voluntary, the direction of travel is certain: mandatory adoption for listed companies is targeted for 1 January 2027. This is not just a minor tweak to the rules. It is a wholesale consolidation of fragmented reporting into a single, internationally aligned architecture.
The FCA’s CP26/5 proposal makes it clear that while climate-related disclosures (S2) will be mandatory, wider sustainability reporting (S1) will initially operate on a “comply or explain” basis. This creates a massive point of tension for firms. If you choose to “explain” why you have not disclosed certain data, such as the notoriously difficult Scope 3 emissions, you must provide clear reasons and a roadmap for future compliance. In the eyes of an investor, an “explanation” is often just a red flag for a lack of data maturity.
The CMA and the 10% threat
While the FCA is busy with reporting standards, the Competition and Markets Authority (CMA) is looking at the claims you make in your marketing and supply chains. Their updated guidance warns that any company repeating or disseminating misleading environmental claims may face enforcement action.
Here is the kicker: under the Digital Markets, Competition and Consumers Act 2024, the CMA can impose administrative fines of up to 10% of global turnover for breaches of consumer protection law. This makes greenwashing a board-level risk. You can no longer hide behind a supplier’s assurance. Retailers and brands are now expected to take “reasonable steps” to verify environmental claims rather than relying blindly on a certificate from an upstream partner.
If your supply chain says your laptops are “sustainable,” you had better have the evidence to back it up. The CMA has signalled that it will prioritise cases involving systemic governance failures. If you do not have internal processes for verifying, approving, and reviewing environmental claims, you are effectively a sitting duck.
The scope 3 headache and the circular solution
The biggest hurdle for most organisations remains Scope 3 emissions: those indirect emissions that hide deep within your supply chain. For many industries, the majority of their carbon footprint is not in their direct operations but in the products they buy.
When you purchase a new laptop, you are not just buying a piece of tech. You are responsible for the 331kg of CO2 emissions generated from manufacturing an average new laptop, the 1,200kg of earth mined to gain the required mineral resource, and 190,000 litres of water used in extracting, refining and using these minerals to make all the laptop components. These figures become staggering once multiplied across the thousands of laptops in a large company IT fleet.
This is where the circular economy stops being a buzzword and starts being a strategic necessity. Moving away from a “take-make-dispose” model is essential to meeting net zero targets. This is not about buying second-hand or refurbished laptops that might lack consistency or reliability. It is about a more rigorous approach.
Circular Computing has pioneered the Circular Remanufacturing Process™, which returns used laptops to “like new” condition. They have provided a framework that moves the perception from “second best” to a genuine alternative to new. A remanufactured laptop prevents the emissions associated with new production, offering a measurable contribution toward Scope 3 reduction.
The Royal Mint’s sustainable shift
The Royal Mint provides a thought-provoking example of how a traditional UK institution can embrace circularity. One of the biggest drivers for The Royal Mint in working with Circular Computing, was the opportunity to improve the sustainability performance of its laptops.
Purchased goods and services make up a significant portion of The Royal Mint’s overall greenhouse gas emissions so they were keen to explore any opportunity that would support more responsible management of resources and drive decarbonisation within the supply chain. Procuring remanufactured laptops enabled the IT team to lower the carbon
footprint of the laptop estate and promote the principles of a circular economy to both internal and external stakeholders.
As the Royal Mint strives to become leaders in sustainable precious metals this specific initiative enabled the IT Team to make its own important contribution to the decarbonisation and wider sustainability ambitions of the business.
The path to reasonable assurance
As we look toward 2027, the level of confidence required for ESG data is rising. Currently, most firms use “limited assurance,” which essentially means an auditor says, “nothing looked obviously wrong”. However, the trend is moving toward “reasonable assurance,” which is a much higher bar, closer to a financial audit.
To get there, you need real-time reporting, automated data collection, and a supply chain that is transparent. You cannot manage what you cannot measure, and you cannot assure what you do not understand.
The answer is integration
So, what is the fulfilling conclusion to this regulatory puzzle? The answer is that sustainability reporting can no longer be a standalone exercise. It must be integrated with your financial reporting, your procurement strategy, and your risk management frameworks.
The tension between regulatory pressure and operational reality is real, but it is also an opportunity. By adopting rigorous standards like the UK SRS early and looking to circular economy partners for your laptops, you are not just avoiding a CMA fine. You are building a resilient, transparent, and truly sustainable business.
Don’t wait for 2027 to start your journey. The green fairy tale is over, it is time to start writing the real story.
