What Is CDP Disclosure?
CDP disclosure is the submission of a company's environmental data through CDP's questionnaire system. Companies complete a structured questionnaire covering their environmental impacts, then submit it through CDP's Portal, where the response can be scored if it is completed by the scoring deadline. For any organization new to sustainability reporting, understanding this basic mechanism is the first step, well before questions of process or scores come into play.
The Purpose of CDP Disclosure
Companies disclose to CDP for one of three reasons. Most respond because investors ask them to, which explains why financial services firms and their portfolio companies are such active participants in the system. Others disclose in response to customer requests, typically when a large buyer wants environmental data from its supply chain. A smaller group discloses voluntarily to signal environmental leadership ahead of any formal request.
The practical purpose is the same across all three cases: to give the market a comparable, standardized account of how a company understands and manages its environmental risks. Once submitted through the Portal, that account becomes visible to the investors and customers who requested it.
What Environmental Topics CDP Covers
CDP structures its questionnaire around three main environmental topics:
-
Climate change, including greenhouse gas emissions, targets, and governance
-
Deforestation, covering forest-risk commodities and land use
-
Water security, addressing water use, risk, and stewardship
Depending on the requests it receives and its sector, a company may respond across one or all three areas. Each is completed and submitted through the same CDP Portal.
How the CDP Disclosure Process Works
CDP disclosure follows a defined sequence, and the platform enforces much of it. You cannot skip ahead, invent your own order, or leave the Submission Lead field empty and still expect a scored response. The steps below map directly to CDP's official How to Disclose guidance for the 2026 cycle. To ground them, we will use a running example: a manufacturer that has just received an investor request to disclose its climate data.
Step 1: Check for Pending Requests in the Portal
Log into the CDP Portal and look for any active investor or customer requests attached to your organisation. Our manufacturer, prompted by an investor letter, would confirm that the request is actually live in the Portal before doing anything else. If no request exists but you want to disclose anyway, you can register voluntarily. Either way, the Portal is the single source of truth for what you have been asked to complete.
Step 2: Confirm Your Submission Lead
CDP requires a named Submission Lead before you can respond to the questionnaire. This is not a formality. The Submission Lead is the accountable owner who controls the response, manages contributors, and ultimately hits submit. For a manufacturer coordinating input across EHS, operations, and finance, naming this person early prevents the classic failure mode where nobody actually owns the deadline. Investor-facing teams in financial services often play this role when responding to their own supply chain requests.
Step 3: Pay the Admin Fee and Complete Setup Questions
An administration fee applies to certain respondents and must be paid before you can proceed. Once it is settled, you complete the setup questions, which determine which questionnaire and modules you receive. Answer these carefully, because they shape everything downstream.
Step 4: Build and Complete Your Questionnaire Response
With setup done, you build your response around the relevant sector-specific modules. Our manufacturer would draw on the modules matched to its industry rather than answering questions that do not apply. Use CDP's Question Bank to map internal data owners to each question before drafting. Knowing who holds the emissions figures, governance details, and target data turns a chaotic scramble into a manageable workflow. This is where disciplined sustainability reporting processes pay off, because the underlying data already exists in structured form.
Step 5: Submit Before the Scoring Deadline
The hard cutoff for a scored response is 16 September 2026. Submit by this date if you want CDP to score your submission. Edits made after it are accepted, but they are not scored. A secondary final close falls in the week commencing 26 October 2026, though you should treat that as a backstop rather than a target. For anyone chasing a score, September is the deadline that matters.
Understanding CDP Scoring: Levels, Bands, and What Drives Your Score
Once a response is submitted through the Portal, CDP evaluates it against a published methodology that rewards not just transparency but demonstrated environmental management. Understanding how that evaluation works is the difference between disclosing for the sake of it and actually improving your position year over year.
The Four Scoring Levels Explained
CDP scores responses across four sequential levels, each representing a deeper stage of environmental maturity:
-
Disclosure measures whether you are transparent and complete in the data you provide.
-
Awareness assesses whether you understand how environmental issues affect your business and how your activities affect the environment.
-
Management evaluates the actions, policies, and processes you have in place to address those issues.
-
Leadership rewards best practices such as ambitious targets, verified data, and governance structures that put you at the front of your sector.
The levels are progressive. You cannot skip to Leadership without first satisfying the criteria beneath it. This is why a technically complete response can still score modestly if it stops at reporting numbers without evidencing the strategy behind them.
How Score Bands Work
CDP translates performance across those four levels into banded scores, moving from lower performance bands toward higher ones. What separates the bands is depth of evidence. Lower bands reflect disclosure and basic awareness, while higher bands require demonstrated management actions and, at the top, leadership indicators such as third-party verification and science-based targets. As CDP's Understand your score as a disclosing company guidance makes clear, banded progression is cumulative, so incremental improvements in data quality and management practices move you up the scale rather than any single silver-bullet answer.
What CDP Actually Scores and What It Ignores
This is the point most teams underestimate: scores are based solely on the data provided in the response itself. Per CDP's Scores and A Lists documentation, external links and attachments are excluded from scoring unless the methodology explicitly permits them for a given question. If your evidence lives in a linked PDF or a website reference, it will not be counted. The answer must stand on its own inside the Portal.
Timing is equally unforgiving. The scoring deadline of 16 September is the cutoff. Edits made after that date are accepted, but they are not scored. Treat 16 September as the hard line for anything you want reflected in your grade.
The practical takeaway is that response quality within the Portal is the only lever you control. That reality is what makes disciplined, evidence-first sustainability reporting so valuable, especially for firms in financial services and other regulated sectors where investors scrutinise every band.
How to Prepare a Strong CDP Submission
The companies that score well on CDP are rarely the ones that write the best answers under deadline pressure. They are the ones that treated preparation as a project months in advance, assigned clear ownership, and used CDP's own tools to structure the work. What follows is a practical framework for doing exactly that, one that goes beyond the official process steps.
Map Internal Data Owners to Each Question Before You Start
Start the data-mapping exercise well before the scoring deadline, not once the questionnaire is open. Pull CDP's Question Bank and work through the modules relevant to your requests, then assign a named internal owner to every question or cluster of questions. Emissions data, governance disclosures, and sector-specific modules each tend to live with different people, and the fastest way to derail a submission is discovering in September that no one owns Scope 3 or the water security section. A sustainability team that maps owners to questions early turns a scramble into a series of scheduled handoffs.
Align Stakeholders Across ESG, Finance, Legal, and Operations
CDP is not an ESG-only exercise. Finance holds much of the quantitative data that supports emissions and financial-risk questions, legal reviews forward-looking statements and disclosure language, and operations owns facility, energy, and process data. For firms in regulated sectors, the coordination burden is heavier still, and our financial services clients often need investor relations and enterprise risk at the table too. Convene these functions early, agree on who signs off, and set a review cadence so no single team becomes the bottleneck. This cross-functional alignment is usually the difference between a Disclosure-band response and a Management or Leadership one.
Use CDP's Question Bank and Reporting Guidance
CDP publishes a Question Bank and an official reporting guidance hub for disclosing companies, and both are underused. The guidance explains what each question is asking for and what evidence supports a stronger answer, which lets you build responses that match the scoring methodology rather than guessing. First-time respondents should also consult CDP's first-time user guidance and disclosure platform guide before touching the Portal, since these cover Submission Lead setup, admin fees, and questionnaire configuration. Structuring your response around CDP's own materials keeps you aligned with how the response will actually be assessed. For teams building a broader program, tie this into your wider sustainability reporting workflow so CDP data does not sit in a silo.
Treat the Scoring Deadline as Your True Submission Date
The 2026 cycle allows edits after 16 September, but those edits are not scored. That makes 16 September the effective deadline for any change you want reflected in your score, regardless of the late-October final close. Build your internal timeline backwards from mid-September, leaving room for legal review and sign-off before submission. If you plan to the final close date instead, you risk finishing on time but scoring on an incomplete draft, which defeats the purpose of disclosing at all.
CDP Submission Checklist: What to Do Before the Scoring Deadline
The CDP disclosure process rewards teams that treat preparation as an operational project rather than a last-minute scramble. Use this checklist as a single reference point in the weeks leading up to the 2026 scoring deadline of 16 September. Work through each item in order, and remember that the final response window closes the week commencing 26 October.
-
Confirm pending requests in the Portal. Log in and check whether investors or customers have requested your disclosure, and identify which questionnaires and sector modules apply.
-
Assign a Submission Lead. CDP requires a confirmed Submission Lead before you can respond, so name this owner early.
-
Pay the admin fee if one applies to your organization.
-
Complete the setup questions to unlock the correct questionnaire structure.
-
Map data owners to questionnaire modules. Assign internal owners to climate, water, deforestation, and governance sections before drafting.
-
Collect and verify emissions and governance data, including Scope 1-3 figures and board oversight details.
-
Complete all relevant sector modules in full, since gaps limit your score.
-
Review your response against the scoring methodology. CDP scores only the data entered in the response, not external links or attachments unless the methodology allows them.
-
Submit by 16 September. Edits after the scoring deadline are accepted but will not be scored.
Before you submit, run a pre-submission internal review with ESG, finance, and legal sign-off. This alignment is standard practice in mature sustainability reporting programs and is especially important for regulated sectors such as financial services, where disclosed data must reconcile with financial and risk records.
CDP Disclosure and Financial Services: Sector Considerations
How Financial Services Firms Approach CDP Disclosure
Financial services firms occupy an unusual position in the CDP ecosystem, because they sit on both sides of the disclosure relationship. A bank, asset manager, or insurer may receive a CDP disclosure request from its own investors while simultaneously requesting environmental data from the portfolio companies and borrowers it finances. Much like a manufacturer asked by shareholders to disclose, a financial institution should first confirm whether it has pending requests waiting in the CDP Portal, then assign a Submission Lead before building its response.
What makes the sector distinct is that CDP applies sector-specific modules to financial services respondents. These modules address financed emissions and portfolio-level exposure rather than only a firm's direct operational footprint, so the questionnaire looks meaningfully different from a standard industrial submission. Mapping internal data owners across risk, investor relations, and sustainability reporting functions early is essential.
Investor Requests and the CDP Portal
Investor-driven requests remain the primary trigger for disclosure in this sector, arriving directly through the CDP Portal. For sector-specific guidance on financed emissions, module structure, and preparation, see our financial services resources.
Frequently Asked Questions About CDP Reporting
What is CDP disclosure?
CDP disclosure is the process of submitting your company's environmental data through CDP's questionnaire system, covering topics such as climate change, deforestation, and water security. Companies disclose in response to investor or customer requests, or voluntarily, by completing the questionnaire in CDP's Portal.
What does CDP score?
CDP scores the level of detail and completeness in a response, the organization's awareness of environmental issues, its management methods, and its progress toward environmental stewardship. Responses advance through four scoring levels: Disclosure, Awareness, Management, and Leadership. The score is based on information entered in the CDP response; external links and attachments are generally excluded unless the scoring methodology specifically requests them.
