The CDP climate disclosure framework 2026 is no longer a voluntary side project for sustainability teams. In 2026, responding to CDP has become a baseline expectation from capital markets, supply chain partners, and regulators worldwide. The numbers back this up: CDP’s Capital Markets Signatories, over 540 financial institutions with US$110 trillion in assets, are requesting over 43,000 organizations to disclose environmental data in the 2026 cycle. In this post, you will learn exactly what has changed in the 2026 questionnaire, why product-level carbon data has become a scoring differentiator, and how companies can build the measurement infrastructure needed to respond with confidence.
Key Takeaways
- The 2026 cycle moves beyond the relatively limited updates seen in 2025, adding new ocean-related questions, broader coverage of forests and other natural ecosystems, and targeted revisions to water security, plastics, and climate change, including adaptation and resilience disclosures.
- For the first time, leading SMEs can achieve an “A” score for Climate Change, a category previously capped at “B.”
- CDP Disclosure 2026 requires companies to provide verified, financially relevant, and decision-useful environmental data, aligned with global frameworks and integrated into business strategy.
- Scope 3 emissions verification, including product-level carbon footprints, has become a key lever for reaching the top-tier A-List score.
- The submission window opens the week of 15 June and closes the week of 14 September for scored submissions.
What Is the CDP Climate Disclosure Framework?
CDP is an international non-profit organization that supports companies, cities, and governments in measuring and managing their environmental impact, and since 2000 it has become the global gold standard for environmental transparency. CDP is aligned with the Task Force on Climate-Related Financial Disclosures (TCFD) framework, which provides recommendations for disclosing information on companies’ climate governance, strategy, risk management, and metrics across the entire supply chain.
CDP Disclosure is a global environmental reporting framework that enables companies to disclose data on climate change, water security, and deforestation to investors, customers, and regulators, and in 2026 it has evolved into a decision-grade data platform, not just a disclosure mechanism. The framework rewards transparency at every level of the value chain: governance, strategy, verified emissions data, and supply chain engagement all feed into a single score that investors and procurement teams use daily.
Twenty-five years since CDP pioneered disclosure, the number of investors backing CDP’s annual request has grown from just 35 to financial institutions representing a quarter of all global institutional financial assets, with companies representing two-thirds of global market capitalization from 130 countries now disclosing critical environmental data through CDP.
Key Changes to the 2026 Questionnaire
Broader Scope, Smarter Set-Up
The 2026 updates to the full corporate questionnaire reflect broader topic coverage, a clearer questionnaire set-up that directs companies only to the questions that apply to them based on their size, activities, and risk, and refinements to existing questions, expanding disclosures in several areas while maintaining a scoring framework centred on climate change, forests, and water security.
One of the most practical upgrades is a technology-driven simplification of the process. In 2026, CDP has introduced technological updates such as improved guidance, navigation support, contextual explanations, the option to opt in to disclose against the most relevant topics during questionnaire set-up, and enhanced data ingestion capabilities so organizations can upload data directly or reuse previously reported information.
Oceans, Forests, and Plastics
The 2026 questionnaire introduces a new environmental theme: Oceans. The questions are available to all companies but are not mandatory and will not be scored, giving companies time to familiarise themselves with ocean-related reporting without affecting their overall grade.
The Forests questionnaire sees an expansion in commodity coverage: in addition to cattle, palm oil, soy, and timber, three new commodities will now be scored: cocoa, coffee, and rubber. Plastics disclosure has also been expanded: new and revised questions cover targets, reuse models, packaging formats, and design for recycling or composting.
Adaptation and Resilience Now Scored
CDP is broadening its framework to capture critical data on how organisations are preparing for and responding to physical environmental risks, as nature loss and climate change present increasing material risks, with this update aiming to equip decision-makers with standardised information to manage uncertainty and unlock investment in adaptation. Climate change remains a scored theme in 2026, with scoring changes designed to incentivise companies to disclose actions taken toward improving adaptation and resilience.
What SMEs Need to Know
The SME questionnaire remains intended as a more proportionate disclosure route for smaller companies, with the 2026 updates broadening the scope of SME disclosures, simplifying parts of the reporting experience, and expanding climate scoring, while leaving the new forests and water security content unscored. The big headline for SMEs is the A-List opportunity: for the first time, leading SMEs can achieve an “A” score for Climate Change, and can now disclose on Forests and Water Security through new unscored modules, with the SME questionnaire expanding from 8 to 10 modules.
Scope 3 and the Product Carbon Footprint Problem
The single biggest stumbling block for companies chasing top CDP scores is Scope 3 emissions. For many companies, recording and validating Scope 3 emissions, the indirect emissions from the value chain, is the biggest challenge in the entire CDP process. At least one category of Scope 3 emissions must be verified to meet the requirements for top-tier performance, making it a strategic priority for organisations aiming for an A-List position.
This is where product-level carbon data stops being an academic exercise and becomes a direct business asset. Consider a single container of body cream. According to Devera’s ISO 14040/44-compliant Monte Carlo LCA, the median carbon footprint of a body cream sits at 2.50 kg CO₂e, with raw materials alone accounting for 47.7% of total impact. For a cosmetics company disclosing supplier emissions through CDP, that granularity, knowing that ingredient sourcing drives nearly half the product footprint, is exactly the kind of decision-useful data the framework now demands. Without it, a company can gesture at supply chain engagement but cannot prove it.
The challenge scales across categories. A plant-based food product carries a median footprint of 3.10 kg CO₂e per kilogram (range: 2.42 to 4.41 kg CO₂e), with raw materials and manufacturing together accounting for over 80% of the impact, according to Devera’s plant-based food benchmark. For food and beverage companies that need to disclose upstream agricultural emissions under CDP’s supply chain module, having ISO-aligned data at the product level is not a nicety; it is the foundation of a credible, scored response. A company that can demonstrate which SKUs fall above or below their sector median is far better placed than one relying on spend-based estimates.
This is why understanding life cycle assessment methodology has moved from the sustainability team’s domain into the CDP strategy conversation.
From Disclosure to Decision: Aligning CDP with Other Frameworks
CDP aligns with major global standards like ISSB (and formerly TCFD) as well as CSRD, giving companies a head start on increasingly mandatory climate disclosure rules. In practice, this means the data you collect for CDP feeds directly into your CSRD reporting obligations and ISSB-aligned financial disclosures, reducing duplication and strengthening overall data quality.
Responding to CDP also helps prepare for mandatory ESG disclosures under regulations like CSRD in Europe, California SB 253 and SB 261 in the US, and IFRS Sustainability Standards adopted via country-specific regulations globally. Think of it as building a shared data infrastructure: every verified carbon figure you produce for CDP is a figure you do not need to recreate for a different regulator.
According to CDP’s Corporate Health Check 2026, organisations reporting via CDP face US$1.47 trillion in reported environmental physical risks, yet only 9% of the companies assessed disclosed physical adaptation investments last year (US$84.5 billion in total), highlighting a major gap in finance disclosures. The 2026 framework’s new adaptation scoring is a direct response to this gap, and companies that invest now in measurement systems will be ahead of the curve when adaptation data becomes a scored essential criterion in future cycles.
For companies also navigating green claims legislation, it is worth noting that the EU Green Claims Directive and CDP increasingly share the same data layer: substantiated, lifecycle-based evidence. Building that layer once serves multiple regulatory masters.
The Proof Gap: Why Data Quality Wins Scores
One of the biggest misconceptions is that CDP reporting is static. In reality, the bar is raised almost every year, meaning that for companies that previously scored well, standing still can result in a lower score even if internal activities have not changed.
CDP will increasingly check whether information on climate-related risks is consistent with financial reports and sustainability strategies. This consistency check is where many B and C-rated companies lose points: their CDP questionnaire tells one story, their annual report tells another, and the gap is visible to any analyst reading both.
The solution is not more spreadsheets. The primary hurdle in CDP disclosure is the “Proof Gap,” moving from knowing to proving. Missing or unverified data points are one of the leading causes of point deductions and lower scores.
Take a laptop as an example of how counter-intuitive product data can be. Devera’s ISO-compliant LCA benchmarks show that the median carbon footprint of a laptop is 215.10 kg CO₂e, with 38.3% attributable to the use phase and 36.5% to raw materials. A technology company that discloses only manufacturing emissions in its CDP Scope 3 response is materially under-reporting. That kind of gap, if spotted during CDP’s consistency checks, directly reduces a score. Product-level LCA data closes it with verifiable, auditable numbers.
CDP itself recognises this trend. CDP’s 2026 updates are designed to strengthen the link between data and action. The ability to calculate product carbon footprints at scale is rapidly becoming the foundation on which credible CDP disclosures are built.
How to Prepare for the 2026 CDP Disclosure Cycle
Getting from where you are today to a scored, defensible CDP response by the September deadline requires structured preparation. The steps below reflect best practice across companies that consistently achieve top-tier scores.
Audit your 2025 data first. Your prior disclosure is your strongest asset. Identify where you lost points and whether those gaps relate to data quality, verification, or missing Scope 3 categories.
Map your Scope 3 categories to product footprints. For manufactured goods, this means linking your CDP response to actual LCA data rather than industry-average emission factors. The difference between a spend-based estimate and an ISO 14040/44-compliant figure is visible in CDP’s consistency checks.
Verify at least one Scope 3 category. At least one category of Scope 3 emissions must be verified to meet the requirements for top-tier performance. Choose the category with the most complete data, and invest in third-party assurance before the submission window opens.
Align your narrative across documents. CDP will increasingly check whether information on climate-related risks is consistent with financial reports and sustainability strategies. A sustainability report, annual report, and CDP response that contradict each other on material climate risks will cost you scoring points.
Start early. The CDP Online Response System typically opens for submissions in Q2 of 2026, with a mid-September deadline for a scored rating. Most experts recommend beginning data collection in Q1 to avoid a last-minute scramble.

Frequently Asked Questions
What is the CDP climate disclosure framework and who needs to use it? CDP Disclosure is a global environmental reporting framework that enables companies to disclose data on climate change, water security, and deforestation to investors, customers, and regulators. CDP reporting is voluntary in a formal sense, but growing pressure from investors, supply chain partners, and regulators makes it de facto mandatory for many enterprises.
What are the biggest changes to the CDP questionnaire in 2026? The full corporate questionnaire changes include new ocean-related questions, broader coverage of forests and other natural ecosystems, and targeted revisions to water security, plastics, and climate change, including the layering in of adaptation and resilience disclosures in existing sections. SMEs also gain access to the A-List for climate scoring for the first time.
How does product-level carbon data help with CDP scoring? CDP requires verified Scope 3 emissions to reach top-tier performance, and product-level carbon footprints (calculated using ISO 14040/44 methodology) are among the most credible forms of verification. They provide auditable, SKU-level evidence that directly addresses supply chain engagement questions and consistency checks across financial and sustainability reports.
When is the deadline for CDP 2026 submissions? The submission window opens the week of 15 June and closes the week of 14 September for responses eligible for scoring, with a later window closing the week of 26 October for unscored submissions. Most practitioners recommend starting data collection in Q1 to allow time for verification and internal review before the scored deadline.
If your team is building the product-level carbon data needed to make your CDP response credible and defensible, Devera’s AI-powered LCA platform calculates ISO 14040/44-compliant product carbon footprints in a fraction of the time traditional methods require, giving you the verified, decision-useful numbers that the CDP climate disclosure framework now demands.
