Reading the New CSRD Signal Across the UK, UAE and South Africa

Regulatory divergence is one of the defining features of global ESG disclosure — and one of the most practically significant for any organisation operating across multiple jurisdictions. Understanding what is mandatory where, what is merely expected by counterparties, and what is genuinely optional requires a level of regulatory fluency that most sustainability functions have not yet fully built.

This briefing takes stock of where the UK, the UAE, and South Africa currently sit in relation to the CSRD signal — and what organisations operating in or across these markets should be preparing for in the near term.

What CSRD actually requires — and why it travels

The Corporate Sustainability Reporting Directive, which entered into force in January 2023 and has been phasing in across EU member states since the 2024 financial year, is the most comprehensive mandatory corporate sustainability reporting regime yet enacted by any major economic bloc. Its scope, as implemented through the European Sustainability Reporting Standards (ESRS), covers:

• Climate-related disclosures (ESRS E1) including Scope 1, 2 and 3 emissions, transition plans, and physical and transition risk assessments
• Environmental topics beyond climate: pollution (E2), water (E3), biodiversity (E4), and circular economy (E5)
• Social topics: own workforce (S1), workers in the value chain (S2), affected communities (S3), and consumers (S4)
• Governance topics: business conduct (G1)
• A double materiality assessment requirement — meaning companies must assess and disclose both how sustainability issues affect the business and how the business affects sustainability

Approximately 50,000 companies are directly in scope. But the indirect scope is considerably broader. A UK-headquartered supplier to a CSRD-obligated European corporate — or a South African manufacturer supplying into an EU value chain — will face CSRD-derived data requests from its customers, regardless of its own jurisdictional obligations.

United Kingdom: The parallel trajectory

The UK's departure from the EU means CSRD does not apply directly — but the UK's own sustainability disclosure architecture has been developing in parallel, and the alignment is closer than the separation suggests.

UK SDR and the ISSB baseline

The Financial Conduct Authority's Sustainability Disclosure Requirements (SDR) establish a sustainability labelling and disclosure regime for UK investment products. The UK government has committed to mandating ISSB-aligned climate disclosure for large UK companies through adoption of IFRS S1 and IFRS S2, building on the TCFD framework that has been mandatory for large UK companies since April 2022.

SECR and ESOS: the existing layer

Streamlined Energy and Carbon Reporting (SECR) requires large UK companies, quoted companies, and large LLPs to disclose energy consumption, Scope 1 and 2 greenhouse gas emissions, and intensity metrics in their annual reports. The Energy Savings Opportunity Scheme (ESOS) Phase 3 requires organisations to submit energy saving action plans demonstrating how identified savings will be pursued — a significant tightening of the previous regime.

What UK organisations should already be doing

For UK-headquartered organisations, the near-term priorities are: ensuring SECR disclosures are built on data of sufficient quality to serve as a credible baseline for ISSB-aligned reporting; conducting a gap assessment against ESRS E1 and ESRS S1 for those supplying into EU value chains; and for property and real estate organisations, assessing readiness against MEES EPC-B trajectory and the associated operational energy intensity benchmarks embedded in green finance criteria.

United Arab Emirates: The accelerating standard

The UAE's ESG disclosure landscape has undergone a transformation since its Net Zero 2050 commitment and its hosting of COP28 in Dubai in 2023 — which placed the UAE's climate governance posture under significant scrutiny and, ultimately, upgraded it.

Securities and exchange disclosure requirements

The Abu Dhabi Securities Exchange (ADX) and the Dubai Financial Market (DFM) both introduced mandatory ESG disclosure requirements for listed companies. For companies listed on Nasdaq Dubai, requirements align more closely with TCFD and, increasingly, ISSB. The UAE Securities & Commodities Authority has signalled ISSB alignment as the direction of travel for the jurisdiction as a whole.

The COP28 effect

One of the less-discussed consequences of hosting COP28 was the acceleration of voluntary-to-mandatory migration in UAE ESG standards. Organisations building UAE operations today that are not designing their ESG data infrastructure to CSRD-equivalent standards are building infrastructure they will need to rebuild within a three-to-five year horizon.

South Africa: The continent's most mature regime

South Africa operates the most developed mandatory ESG and integrated reporting regime on the African continent — one that predates CSRD by more than a decade in some of its most important features.

JSE Sustainability Disclosure Guidance and King IV

The Johannesburg Stock Exchange's Sustainability and Climate Disclosure Guidance requires JSE-listed companies to disclose in alignment with TCFD for climate-related risks. King IV — the King Report on Corporate Governance for South Africa — has since its 2016 edition required integrated reporting, with sustainability performance integral to the governance narrative rather than an appendix to it.

GRI and the broader African investor landscape

The Global Reporting Initiative (GRI) Standards are the dominant voluntary reporting framework across South Africa and the wider SADC region. GRI alignment provides a workable bridge to CSRD — the ESRS standards were designed with interoperability with GRI in mind — meaning that South African organisations with established GRI reporting programmes have a shorter distance to travel to meet CSRD-derived data requests than their counterparts in markets where voluntary reporting has been less systematically adopted.

The three-market comparison

What this means for your environmental data infrastructure

The practical implication of the converging regulatory signals across these three markets is that the quality bar for environmental data — not just its existence — is rising simultaneously across all of them. This has three specific consequences for how organisations should be thinking about their monitoring and reporting architecture.

The double materiality requirement is coming whether or not you are in CSRD scope

CSRD's double materiality assessment — the requirement to assess both how sustainability issues affect the business financially and how the business affects the environment and society — is the most substantive methodological shift in ESG reporting that the international framework landscape has produced since the initial emergence of integrated reporting. UK, UAE and South African organisations that begin developing their double materiality methodology before it becomes mandatory will be better positioned both in capital markets and in supply chain negotiations with CSRD-obligated counterparties who are already asking for it.

Scope 3 is where the data gap is largest — and most exposed

Across all three markets, Scope 3 emissions represent both the largest component of most organisations' carbon footprints and the most poorly evidenced component of their disclosure. ESRS E1 requires a Scope 3 assessment and, for material categories, quantified disclosure. Organisations that cannot produce defensible Scope 3 estimates are building a disclosure gap that will compound over time.

Third-party verified data will separate credible from compliant

There is an important distinction emerging between organisations that are compliant with applicable disclosure requirements and organisations whose disclosures are credible to sophisticated counterparties. The differentiating factor is independent, third-party verified environmental data. Self-reported figures, even when technically accurate, carry an increasing credibility discount in institutional capital allocation.

What to do now

• Conduct a double materiality pre-assessment

  Map your sustainability topics against the ESRS topical standards. Identify which are material on financial grounds, which are material on impact grounds, and which require evidence you do not yet have.

• Audit the quality of your Scope 1, 2 and 3 data

  Not just whether you have the data, but whether it was collected under a methodology that will withstand third-party assurance review. Self-reported estimates against utility invoices will not be sufficient for ISSB-aligned disclosure.

• Engage your supply chain on Scope 3 data collection

  For organisations with material upstream or downstream emissions, proactive engagement with key supply chain partners on emissions data is now a competitive preparation activity, not an optional enhancement.

• Identify the CSRD-obligated entities in your value chain

  Map which of your customers, investors, and lenders are directly subject to CSRD. Those relationships will generate formal ESG data requests — knowing they are coming enables you to build the response infrastructure before the request arrives.

• Commission independent environmental baseline monitoring

  Air quality, energy, and infrastructure monitoring conducted to a recognised international standard — WHO, CIBSE, ISO 50001, GRI, TCFD — produces the independently verified evidence that underpins credible disclosure across all three markets.
