CDP reporting standards: how CDP maps to TCFD, ISSB, GRI and SASB
CDP reporting standards are CDP’s own — an annual questionnaire and scoring methodology — deliberately aligned with the frameworks companies already use.
CDP says IFRS S2 has been its climate baseline since 2024, and that its climate questions have tracked the TCFD recommendations since 2018.
None of that makes CDP a legal requirement, and this page maps where each framework sits and what each is for.
A category check
CDP compliance: a voluntary platform, not a legal duty
There is no such thing as CDP compliance.
CDP is a voluntary, privately run environmental disclosure and scoring platform, and it describes itself as running “the world’s only independent environmental disclosure system”.
No UK, EU or other instrument requires anyone to disclose to CDP, and a CDP score has no regulatory status.
Disclosure is driven by commercial pressure: in 2026 CDP’s Capital Markets Signatories — over 540 financial institutions with US$110+ trillion in assets — are asking more than 43,000 organisations to disclose, alongside buyers in CDP’s Supply Chain programme.
CDP does not check what is submitted: its 2026 scoring introduction says “neither CDP nor CDP’s scoring partners verify the information in any individual organization’s response”.
The one regulator to have spoken on CDP scores acted to restrict them: CDP’s notice cites the Securities and Exchange Board of India (Credit Rating Agencies) Regulations 1999.
CDP Worldwide is, as at 30 September 2026, a UK registered charity (no. 1122330); in June 2026 CDP announced a split into a Permira-backed commercial company and a charitable CDP Foundation, saying “the evolving regulatory environment means CDP is required to adapt its structure”.
That changes CDP the organisation; it does not give a CDP score any regulatory status.
What compliance actually requires is set out on UK carbon reporting requirements and ESG reporting requirements in the UK.
SECR — energy and carbon in the annual report.
Companies Act 2006 s.414CB — climate-related financial disclosures.
UK SRS under the FCA’s final rules — comply-or-explain for listed companies in scope, from periods beginning 1 January 2027.
A CDP response is a filing under none of them.
The reporting stack
CDP, TCFD, ISSB, GRI and SASB: how the frameworks relate
They are not competing standards. They sit at different points in the same reporting stack, and answer different questions.
| Framework | What it is | Owner today | UK legal status |
|---|---|---|---|
| TCFD | Climate disclosure recommendations: four pillars, eleven recommended disclosures (2017) | Task force disbanded 12 Oct 2023; monitoring passed to the IFRS Foundation | Not itself law; its structure underpins the Companies Act and Listing Rule climate disclosures |
| IFRS S1 and S2 | The ISSB's general and climate standards; S2 is consistent with the TCFD recommendations | ISSB (IFRS Foundation) | Not law in the UK; adopted as UK SRS |
| UK SRS S1 and S2 | The UK's versions of IFRS S1 and S2, published 25 Feb 2026 | Department for Business and Trade | Voluntary, except that PS26/19 requires listed companies in scope to report or explain from 2027 |
| CDP | Voluntary environmental disclosure and scoring platform | CDP Worldwide — a UK charity, split announced June 2026, not complete | None |
| GRI | Impact-reporting standards: an organisation's impacts on the economy, environment and people | Global Reporting Initiative (a Dutch foundation) | No UK instrument requires it |
| SASB | Industry-based, financially material disclosure topics and metrics for 77 industries | ISSB (IFRS Foundation) since August 2022 | UK SRS may refer to it; IFRS S1 requires reference to it |
TCFD supplied the climate-risk structure that CDP’s climate questions, IFRS S2 and UK SRS S2 all use.
GRI reports an organisation’s impact on the world; the ISSB standards and SASB report what is financially material to the organisation itself.
CDP sits across both: a questionnaire built on IFRS S2 for climate, partly aligned with GRI and TNFD for nature, and scored by CDP.
CDP and TCFD
CDP and TCFD: the four pillars, in the 2026 modules
CDP says its climate change datapoints have been aligned with the TCFD recommendations since 2018, turning the four pillars into questions in a standard annual format.
But the TCFD itself no longer exists as a body: it disbanded on 12 October 2023, having fulfilled its remit, and the FSB asked the IFRS Foundation to take over monitoring of companies’ climate-related disclosures.
The task force’s own website now carries that notice, and the IFRS Foundation took on the monitoring from 2024.
So CDP is aligned with a frozen text, not an active task force.
The pillar structure lives on in IFRS S2, which the IFRS Foundation says is consistent with the TCFD’s four core recommendations and eleven recommended disclosures — and which then asks for more, including industry-based metrics.
In the UK, TCFD-aligned disclosure is still law through Companies Act 2006 s.414CB; what the UK rules require is on TCFD reporting.
| TCFD pillar | Where CDP asks it (2026) |
|---|---|
| Governance | Module 4 — governance: board oversight, management responsibility, incentives |
| Strategy | Modules 3 and 5 — risks and opportunities with substantive effect; business strategy, scenario analysis, transition plans |
| Risk management | Module 2 — processes for identifying, assessing and managing risks |
| Metrics and targets | Module 7 — emissions, energy and targets; plus Module 13 verification |
CDP, the ISSB and UK SRS
CDP and IFRS S2: the climate baseline
CDP calls itself the ISSB’s key global climate disclosure partner, and says the ISSB’s climate standard is “the foundational baseline for CDP’s climate disclosure”.
Since 2024 its questionnaire has been aligned with IFRS S2 Climate-related Disclosures, issued by the International Sustainability Standards Board.
UK SRS S1 and S2 are the UK’s versions of IFRS S1 and S2, published by the Department for Business and Trade on 25 February 2026; the texts are on UK SRS standards.
Under the FCA’s final rules (PS26/19, 30 September 2026), listed companies in scope report against UK SRS on a comply-or-explain basis for accounting periods beginning on or after 1 January 2027, with first reports in 2028.
Outside those listing categories UK SRS is voluntary, and no private-company requirement has been proposed.
So a company answering CDP has gathered much of what UK SRS S2 asks for — governance, strategy, risks, emissions and targets — but the two remain separate disclosures, with different boundaries and publication routes.
CDP and GRI
CDP and GRI: partial alignment, new climate standards in 2027
GRI and TCFD answer different questions: GRI reports an organisation’s most significant impacts on the economy, environment and people; TCFD and IFRS S2 report climate-related risks to the organisation.
CDP says its questionnaire is partially aligned with GRI’s Climate Change (102), Energy (103), Water and Effluents (303) and Biodiversity (101) standards, and that CDP and GRI have jointly mapped GRI 102 and 103 to the 2026 questionnaire.
GRI’s climate standard is changing: GRI 102: Climate Change 2025 takes effect on 1 January 2027, and GRI 305: Emissions 2016 is withdrawn when it does.
Until then, GRI 305 remains the current emissions standard.
Beware the numbering: since 2024 GRI 101, 102 and 103 mean biodiversity, climate and energy, whereas a 2016-era “GRI 102” meant General Disclosures.
GRI and the IFRS Foundation have said that an organisation reporting under both GRI 102 and IFRS S2 can use its IFRS S2 Scope 1, 2 and 3 disclosures to meet the corresponding GRI 102 requirements, measured under the GHG Protocol.
Beyond emissions, no disclosure-level GRI–ISSB correspondence table had been published as at 10 September 2026.
| GRI standard | Status | CDP alignment |
|---|---|---|
| GRI 101: Biodiversity 2024 | Effective 1 Jan 2026 | Partial |
| GRI 102: Climate Change 2025 | Effective 1 Jan 2027 | Partial; joint mapping |
| GRI 103: Energy 2025 | Effective 1 Jan 2027 | Partial; joint mapping |
| GRI 303: Water and Effluents | In effect | Partial |
| GRI 305: Emissions 2016 | Withdrawn when GRI 102 takes effect | — |
SASB climate risk reporting
SASB: industry metrics, now the ISSB’s
The SASB Standards set out industry-based sustainability disclosure topics and metrics, including climate-related ones, for 77 industries classified by SICS.
The ISSB is responsible for the SASB Standards, which passed to the IFRS Foundation when it consolidated with the Value Reporting Foundation in August 2022.
IFRS S1 requires an entity to refer to and consider the applicability of the SASB disclosure topics.
The UK deliberately softened this: in UK SRS several of those references say “may”, though UK SRS S2 ¶37 keeps “shall” for the metrics used to set and monitor targets.
So an entity claiming IFRS S1 compliance is in a different position from one claiming UK SRS S1 compliance on this point.
CDP does not use SASB’s industry classification: its sector questions come from its own Activity Classification System, as explained on the CDP reporting framework.
The ISSB is also running a project to enhance the SASB Standards, and most of the amendments it has proposed are not yet final.
“Shall” or “may”: the UK divergence
| Provision | Verb |
|---|---|
| IFRS S1 ¶55(a) | Shall refer to the SASB Standards |
| UK SRS S1 ¶¶55(a), 58(a) | May refer to them |
| UK SRS S2 ¶¶12, 32 | May |
| UK SRS S2 ¶23 | Shall (cross-industry) and may (industry-based) |
| UK SRS S2 ¶37 | Shall, for metrics used for targets |

In practice
One data set, several frameworks
A company preparing a CDP response is often mapping the same data several ways at once: GRI for its impacts, SASB for what is financially material in its industry, and the TCFD structure carried into IFRS S2 and UK SRS S2.
None requires abandoning the others, and the greenhouse gas figures, measured under the GHG Protocol, are the part that travels furthest.
In the UK the statutory pieces sit in streamlined energy and carbon reporting, the TCFD-aligned Companies Act disclosures and, for listed companies in scope, UK SRS.
CDP’s structure is on the CDP reporting framework, its themes on CDP environmental reporting, and the hub on CDP reporting.
CDP’s own guidance is the place to check question-level alignment tags, which the Portal shows under each question.

As at 30 September 2026
The dates CDP publishes, 2026 and 2027
CDP’s reporting framework is updated every cycle, and its dates move with it.
The Terms of Disclosure defined the 2026 Scoring Deadline as 16 September 2026 and the Questionnaire Closure Date as 28 October 2026, with scores in the week of 30 November.
CDP has published 2027 dates that are roughly three months earlier: the window opens on 14 April 2027 and the scoring deadline is 23 June 2027.
CDP describes the 2027 window as “one month shorter than in previous cycles”: 14 April to 23 June is 70 days, against 93 from 15 June to 16 September in 2026.
Under §5.4 of its Terms, any date “may be subject to change and modified by CDP at its sole discretion at any time”; the full comparison is on the CDP reporting timeline, and scoring on CDP scores.
What CDP charges is on CDP pricing.

| Questionnaire closes | 28 October | 25 August |
| Scores | w/c 30 November | Sept (disclosers) / Nov (public), aim |
Frequently asked
CDP reporting standards — frequently asked
What reporting standards does CDP follow?
CDP writes its own questionnaire and scoring methodology, and aligns them with other standards. It says the ISSB's IFRS S2 has been the foundational baseline for its climate questions since 2024, that its climate datapoints have been aligned with the TCFD recommendations since 2018, and that it follows the GHG Protocol for emissions. It describes itself as substantially aligned with the pre-Omnibus ESRS E1, and partially aligned with TNFD and with GRI 101, 102, 103 and 303.
Is there such a thing as CDP compliance?
No. CDP is a voluntary disclosure and scoring platform, not a law or a compliance regime, and no UK, EU or other instrument requires anyone to disclose to it. A CDP score has no regulatory status. The UK regimes that are compliance obligations — SECR, the Companies Act climate-related financial disclosures and, for listed companies in scope, UK SRS on a comply-or-explain basis — sit elsewhere, and a CDP response is not a filing under any of them.
How does CDP relate to TCFD?
CDP has aligned its climate questions with the TCFD recommendations since 2018: governance, strategy, risk management, and metrics and targets. The TCFD itself disbanded on 12 October 2023, and the FSB asked the IFRS Foundation to take over monitoring of companies' climate-related disclosures. The TCFD's structure lives on in IFRS S2, which the IFRS Foundation says is consistent with the TCFD's four core recommendations and eleven recommended disclosures.
How does CDP relate to the ISSB and UK SRS?
CDP describes itself as the ISSB's key global climate disclosure partner and uses IFRS S2 as the baseline for its climate disclosure. UK SRS S2 is the UK's version of IFRS S2, published by the Department for Business and Trade on 25 February 2026. Under the FCA's final rules (PS26/19, 30 September 2026), listed companies in scope report against UK SRS on a comply-or-explain basis for accounting periods beginning on or after 1 January 2027.
How does CDP relate to GRI?
CDP says its questionnaire is partially aligned with GRI's Climate Change (102), Energy (103), Water and Effluents (303) and Biodiversity (101) standards, and that CDP and GRI have jointly mapped GRI 102 and 103 to CDP's 2026 full corporate questionnaire. GRI 102 and GRI 103 were published in 2025 and take effect on 1 January 2027, when GRI 305: Emissions 2016 and GRI 302: Energy 2016 are withdrawn.
What is SASB climate risk reporting?
The SASB Standards set out industry-based sustainability disclosure topics and metrics, including climate-related ones, for 77 industries. The ISSB has been responsible for them since August 2022. IFRS S1 requires an entity to refer to and consider them; UK SRS changed that to "may" in several paragraphs, though UK SRS S2 paragraph 37 keeps "shall" for target metrics. CDP's own questionnaire is sector-specific through its Activity Classification System rather than through SASB.
Can one data set serve CDP, TCFD, IFRS S2 and GRI?
Largely, for greenhouse gas figures measured under the GHG Protocol. GRI and the IFRS Foundation have stated that an organisation reporting under both GRI 102 and IFRS S2 can use its IFRS S2 Scope 1, 2 and 3 disclosures to meet the corresponding GRI 102 requirements, once GRI 102 is in effect. Beyond emissions, no disclosure-level GRI–ISSB correspondence table had been published as at 10 September 2026, so each framework still needs its own check.
