The unavoidable truth

Why CDP reporting is no longer optional

The corporate transparency mandate

Who’s asking and why

In the modern market, environmental disclosure is no longer a corporate social responsibility footnote. It’s a critical financial requirement. The CDP (formerly the Carbon Disclosure Project) environmental questionnaire is the world’s leading framework for disclosing environmental performance against themes like climate, forests, water, biodiversity, and plastics—and its reach is expanding dramatically. In 2025, 22,100 companies representing over half of global market capitalization provided data to CDP.

The primary drivers are two powerful groups: global investors and major purchasing organizations. Investors representing over $127 trillion in assets use CDP data to evaluate climate-related financial risk in their portfolios. A company’s environmental data is now fundamental to due diligence, sitting alongside traditional metrics.

Similarly, 270+ major corporate purchasers known as CDP Supply Chain Members use the questionnaires to manage supply chain risk and meet their own emissions reporting and net-zero commitments. These members include some of the largest and most well-known companies in the world, such as Walmart, Dow, Bristol Myers Squibb, Beiersdorf, HP, Bosch, Intel, Lenovo, L’Oreal, Microsoft, Salesforce, Nike, Elevance Health, Hyundai, Electrolux, Itau Unibanco, Singtel, HPE, and Lloyds. If you’re a supplier, a poor or absent CDP disclosure score can be a direct barrier to winning and maintaining major contracts.

Decoding the scorecard

Where the market ranks you

The CDP reporting framework’s scoring system is designed to measure the maturity of your environmental program. Each environmental theme is scored separately at each of four levels. To progress, companies must demonstrate commitment and action:

  • Disclosure (D): Simply providing information, though often incomplete
  • Awareness (C): Demonstrating oversight of environmental impacts
  • Management (B): Taking active steps and implementing policies to reduce impact
  • Leadership (A): The coveted top tier, reserved for companies demonstrating best practices and comprehensive climate strategy

CDP has defined minimum criteria at each tier — called Essential Criteria — that must be met before a company can level up. For top-tier disclosers that choose to make their score public, it is a powerful signal. Top scores attract capital and contracts while low scores signal potential regulatory risk and operational inefficiency. The score is a direct market valuation of your company’s resilience.

The friction points

Data gaps and timeline confusion

While the imperative is clear, the path is fraught with challenges for corporate sustainability teams:

Data gaps: The questionnaire requires granular, global data on emissions, energy, water use, and deforestation. For complex, multi-site organizations, pulling this data from disparate systems — especially across Scope 3 supply chain emissions — is a significant undertaking. Often, estimates are needed where primary data is unavailable. The impacts of environmental dependencies, risks, and opportunities should be quantified financially. The lack of standardized, unified data sources creates friction and often leads to incomplete submissions.

Timeline confusion: The annual cycle is fast and unforgiving. The CDP disclosure window opens in mid-June and closes in mid-July. Companies often struggle to align internal sustainability reporting cycles with the external CDP submission deadline, leading to rushed, last-minute data collection that compromises quality and score potential. This necessitates proactive planning so that greenhouse gas (GHG) emissions data, reduction initiatives, progress on the transition plan, and third-party verification are all ready in time for submission.

The new mindset

A strategic tool for value creation

The goal is not to merely comply with a reporting requirement. The CDP reporting process is a framework for strategic advantage. Instead of treating it as a burdensome year-end checklist, the world’s most successful companies leverage the process to:

  1. Identify and mitigate risk: The rigorous data gathering process forces internal teams to map and understand their highest-risk environmental exposures, allowing them to proactively plan for physical and transition climate risks within their value chain.
  2. Unlock capital: Investors are increasingly prioritizing companies with high environmental performance. A top score differentiates you, potentially lowering the cost of capital and opening access to new pools of Environmental, Social, and Governance (ESG)-focused investment.
  3. Drive operational efficiency: The drive to measure and report emissions and resource use is fundamentally a drive to eliminate waste, leading to direct cost savings in energy and materials.

The message is clear: your CDP score is a public-facing measure of your company’s future-readiness. The time for treating it as a compliance checkbox is over. It is now a critical strategic tool for securing your competitive position in a climate-aware economy.

Frequently asked questions

Does my company have to complete a CDP disclosure?

CDP reporting is not universally mandated by law, but it is increasingly required in practice. If your company is a supplier to any of the 270+ CDP Supply Chain Members — including Walmart, Microsoft, Nike, and others — you may receive a direct request to complete the questionnaire. Investors managing over $127 trillion in assets also use CDP data for portfolio risk assessment. In this environment, opting out carries real commercial and financial consequences.

CDP’s Leadership tier (A) requires companies to demonstrate comprehensive climate strategy, best-practice disclosure across all relevant environmental themes, and evidence of measurable action — not just policy commitments. Companies must first meet Essential Criteria at each lower tier before advancing. Reaching Leadership status typically requires robust Scope 1, 2, and 3 emissions data, validated targets, board-level oversight, and third-party verification.

Requirements vary by environmental theme, but climate disclosures typically require Scope 1, 2, and 3 GHG emissions data, energy consumption figures, emissions reduction targets and progress, governance structures, climate risk assessments, and financial quantification of environmental impacts. Scope 3 supply chain data is among the most challenging to gather and is increasingly weighted in scoring.

The annual CDP disclosure window typically opens in mid-June and closes in mid-July. Given the volume and complexity of data required, companies that wait until the window opens often produce rushed, lower-quality submissions. Best practice is to begin collecting data well in advance — ideally as a continuous process throughout the year — so verification and internal review can be completed before the deadline.

Third-party verification is not required to submit, but it is a significant factor in achieving higher scores. CDP’s scoring methodology rewards verified data, and Leadership-tier companies almost universally have their GHG emissions independently verified. Building assurance into your annual reporting cycle — rather than treating it as a one-time effort — strengthens your submission and your overall credibility with investors and customers.

Greenplaces supports the foundational work that makes CDP reporting possible: building a GHG Protocol-aligned carbon footprint across Scope 1, 2, and 3 emissions, maintaining a clean and auditable data trail, and producing assurance-ready documentation. Our carbon accounting platform and expert team ensure your emissions data is accurate, verified, and structured to meet the requirements CDP scoring demands — so you walk into the disclosure window prepared, not scrambling.
