CDP disclosure 2026 is a strategic imperative

CDP has evolved into a strategic business tool, helping organizations convert environmental data into actionable insights, strengthen resilience, and meet increasing market expectations. In 2025, 640 investors representing US$127 trillion in assets and 270+ major buyers requested environmental disclosures from companies and suppliers through CDP.

With 23,100+ organizations disclosing environmental information and 800+ companies achieving A list recognition, CDP continues to be a key benchmark for environmental leadership, risk management, and transparent decision-making.

Momentum for environmental transparency continues to grow in 2026 as markets demand reliable, actionable data.

CDP 2026 briefly: What's new this year?

The CDP 2026 disclosure cycle introduces important updates designed to improve data quality, strengthen alignment with global sustainability frameworks, and help organizations move from disclosure toward measurable environmental action.

Key changes in corporate questionnaires

  1. New topic - ocean disclosure

    CDP 2026 expands its environmental disclosure framework to include the ocean, addressing a critical area that has historically been underreported despite growing market demand for reliable data. In 2026, organizations responding to CDP's full corporate questionnaire can opt in to ocean disclosure, with greater encouragement for sectors with significant ocean-related impacts, such as fishing and aquaculture, shipping, and offshore energy.

    The new ocean-related questions will follow CDP's existing disclosure approach, helping organizations build a more integrated understanding of environmental impacts across climate, nature, water, and marine ecosystems.

    Importantly, ocean disclosure will be unscored in 2026, giving organizations time to establish data collection processes, strengthen governance, and prepare for future expectations around ocean-related transparency.

  2. Expanding focus on forests and natural ecosystems

    CDP continues to expand its focus beyond forests to address broader land-related dependencies, impacts, risks, and opportunities across commodity supply chains. CDP has expanded commodity coverage by introducing scoring for cocoa, coffee, and rubber, in addition to existing high-impact commodities such as cattle, palm oil, soy, and timber.

    Scoring will be standardized across all seven key commodities, enabling a more complete assessment of how organizations identify, manage, and address deforestation and ecosystem risks within their supply chains. CDP has also refined the essential criteria applied for the commodity disclosures. CDP will provide commodity sub-scores this will now include sub-scores for cocoa, coffee, and rubber, in addition to the other four commodities.

  3. Strengthening water security disclosure

    CDP 2026 enhances water security disclosure to improve transparency around how organizations assess water-related risks, reduce impacts, and manage freshwater resources sustainably. CDP introduced new reporting requirements on wastewater treatment levels, discharge volumes, and compliance with regulatory requirements. These updates strengthen alignment with the GRI 303: Water and Effluents Standard and provide clearer insight into organizations' wastewater management practices.

    Organizations will be able to disclose progress against Science Based Targets Network (SBTN) freshwater methodologies, including whether they have completed the assessment phase and whether freshwater quantity and quality targets have been validated through the Accountability Accelerator.

    Water security disclosures will be fully scored in CDP 2026. Scoring will place greater emphasis on compliance with regulations, validated science-based freshwater targets, and effective management of water pollutants, enabling stronger recognition of organizations demonstrating leading water stewardship.

  4. Scaling plastics disclosure

    CDP 2026 expands plastics disclosure to support the transition from a linear plastics model toward a circular economy. Organizations responding to the full corporate questionnaire can opt in to report plastics-related impacts and practices.

    New and modified questions improve alignment with the Ellen MacArthur Foundation Global Commitment, covering plastics targets, packaging formats, recyclable and compostable design, and reuse models. CDP has placed greater emphasis on transparency. Companies now can disclose their progress on circularity on plastic, reduction targets, packaging strategies, and adoption of reuse solutions.

    Plastics disclosures will remain unscored in CDP 2026, allowing organizations time to establish data collection processes and prepare for future expectations.

  5. Strengthening climate change disclosure

    Climate Change is the foundational baseline for all reporting within the CDP it serves as an entry point for corporate transparency, requiring organizations to report fundamental data like GHG emissions inventories and energy use

    CDP continues alignment with the GHG Protocol Corporate Standard, Organizations are required to begin preparing for future reporting requirements under the GHG Protocol Land Sector and Removals Standard (LSRS), although quantitative land-sector emissions and removals data and will not be required in 2026.

    CDP has refined energy-related reporting to improve consistency with the GHG Protocol and enhance renewable energy data quality. RE100 members will need to provide additional information on renewable electricity sourcing, including time matching, supply agreement duration, and biomass co-firing.

    Climate change will remain scored and scoring requirements are adjusted to reflect the transition to new land-sector requirements, with some agriculture-related questions removed from scoring. Energy and renewable energy scoring will also be streamlined and clarified to improve consistency and comparability.

  6. Strengthening adaptation and resilience disclosure

    CDP 2026 increases focus on climate adaptation and resilience, recognizing that physical climate and nature-related risks are creating growing impacts on businesses, communities, and ecosystems.

    Alignment with TCFD and TNFD approaches questions across modules 2, 4, 5, 11, 12, and 14 strengthen reporting on adaptation actions and give opportunities to organization to disclose they are addressing adaptation and resilience.

    CDP has made minor scoring methodology updates to encourage organizations to disclose concrete actions taken to improve adaptation and resilience. Overall, CDP 2026 reinforces the shift from identifying climate risks to demonstrating proactive measures that build long-term business resilience.

Key Changes in the SME Questionnaire

CDP 2026 introduces key updates to make environmental disclosure more accessible and relevant for small and medium-sized enterprises (SMEs), with expanded coverage of nature-related topics, improved climate scoring opportunities, and simplified guidance.

SMEs can now voluntarily disclose dedicated information on forests and water-related impacts through new modules covering commodities, traceability, deforestation-free practices, water accounting, monitoring, and targets. Leading SME's can now achieve an SME A score for climate change, providing greater recognition for organizations demonstrating strong climate action. CDP has introduced simplified guidance and usability by giving clearer language, concept overviews, rationale sections, and example responses to help SMEs better understand and complete disclosures.

SME forests and water security disclosures will not be scored in 2026, allowing CDP to collect data and develop meaningful scoring approaches for future cycles.

Scoring and Essential Criteria Updates for 2026

  • CDP 2026 scoring continues to evolve alongside the questionnaire, with a stronger focus on environmental risk management, transparency, and leadership-level action.
  • Scoring structure remains consistent organizations responding to the full corporate questionnaire will continue receiving separate scores for Climate Change, Forests, and Water Security. Biodiversity, Plastics, and Ocean disclosures will remain unscored in 2026.
