CDP vs EcoVadis: what they measure, how they differ, and when to use each

Increasingly, companies are required to achieve and maintain specific scores, such as CDP Leadership or an EcoVadis medal, to remain in customer supply chains. These assessments are no longer just reporting exercises, they can directly influence commercial relationships and revenue.

This article explains what each framework is designed to do, how they differ, and how to use them in a way that supports both disclosure and commercial performance.

At a glance: CDP vs. EcoVadis

CDP: measuring and disclosing environmental performance

CDP is a global environmental disclosure system that enables companies to report structured data on climate, water, and forests, with a strong emphasis on risks, impacts, and governance. 

In 2024, more than 24,800 companies disclosed through CDP. For the 2026 disclosure cycle, the platform will also include questions on oceans through the full questionnaire.

Companies provide detailed information on emissions, environmental impacts, climate-related risks and opportunities, targets, transition plans, and value chain exposure. This data forms the basis of CDP’s scoring, which ranges from A to D-, for material environmental topics (Climate, Forests, Water).  

The result is a scored assessment that indicates how advanced a company’s disclosure and environmental management practices are. The Leadership band (A or A-) represents the highest level of environmental performance and has become increasingly difficult to achieve, reflecting CDP’s principle of continuous improvement. Biodiversity, Plastics and Oceans questions are not yet scored (but may be in future).

CDP’s primary audiences include investors assessing risk and capital allocation, regulators and policymakers, and large customers requesting standardized environmental data and detailed disclosures about environmental impact, dependency, and risk management processes. 

The framework aligns closely with financial and regulatory frameworks such as TCFD and the GHG Protocol, which is why it often sits close to financial reporting and is increasingly relevant in the context of CSRD.

In practice, CDP helps answer a specific question: How exposed is your business to environmental risk, and how well are you managing it?.

EcoVadis: ESG performance for supply chain decisions

EcoVadis is a sustainability rating platform used primarily in procurement and supply chain contexts. It evaluates how well a company manages ESG topics across environment, labor and human rights, ethics, and sustainable procurement.

The assessment is evidence-based. Companies must submit policies, actions, and supporting documentation that demonstrate how sustainability is implemented in practice, not just described at a high level.

Based on this, EcoVadis assigns a score from 0 to 100. Companies that meet defined score thresholds and rank within top performance percentiles are awarded medals ranging from Bronze to Platinum, which benchmark their performance relative to peers.

The primary audience is commercial stakeholders. Procurement teams, supply chain managers, and B2B customers use EcoVadis to assess supplier risk and inform sourcing decisions. It is widely embedded in supplier onboarding, RFPs, and ongoing vendor evaluation, providing a standardized framework to compare companies across ESG criteria, particularly within complex, global supply chains.

In practice, EcoVadis answers a different question: Does your company have robust ESG practices in place to support a responsible business relationship?

The commercial stakes: why these scores matter

For many companies, CDP and EcoVadis are not just disclosure frameworks, they are commercial requirements.

Large corporates increasingly embed them into procurement and supplier management. Through programs such as CDP’s Supply Chain initiative, buyers request environmental disclosure directly from suppliers. Similarly, EcoVadis scorecards are commonly used in onboarding, tenders, and ongoing vendor evaluation, often with defined minimum thresholds.

This turns both frameworks into gatekeepers of market access. Suppliers may be required to maintain a CDP Leadership score or achieve an EcoVadis medal (often Silver or above) to qualify for or retain business. Falling below these levels can trigger corrective action plans, increased scrutiny, or exclusion from future opportunities.

Maintaining these scores is not static. EcoVadis medals are awarded on a relative basis, meaning thresholds can shift as overall performance improves. CDP scoring also evolves annually under its continuous improvement model, requiring deeper disclosure, stronger data quality, and more credible transition planning to remain in the Leadership band.

As a result, companies invest significant effort each year not just to improve scores, but to retain them. In this context, CDP and EcoVadis are not only sustainability assessments, they are embedded in commercial decision-making, influencing revenue, customer retention, and competitive positioning.

The key difference: disclosure versus performance assessment

The fundamental difference between CDP and EcoVadis lies in their purpose and evaluation logic.

• Depth vs. breadth: CDP goes deep on environmental topics, particularly climate, with detailed metrics, risk analysis, and forward-looking transition plans. EcoVadis takes a broader ESG view, covering environment, labor and human rights, ethics, and sustainable procurement.
• Disclosure vs. management systems: CDP assesses the quality of a company’s environmental disclosure, including data, targets, risks, and governance. EcoVadis evaluates the strength of a company’s management systems, based on documented policies, actions, and controls across ESG topics.
• Financial vs. commercial lens: CDP is primarily used by investors, regulators, and financial stakeholders to assess exposure to environmental risk. EcoVadis is used by procurement teams and B2B customers to evaluate supplier reliability and ESG performance in commercial relationships.

A practical way to interpret this is that CDP evaluates how well a company understands, measures, and discloses its environmental risks and impacts, while EcoVadis evaluates how well the organisation is structured to manage ESG risks and responsibilities in day-to-day operations.

The synergy: how they work together

There is no formal integration between CDP and EcoVadis, but they are highly complementary and often rely on the same underlying work.

• Overlapping inputs: Both frameworks draw on core ESG elements such as GHG emissions data, climate policies and targets, governance structures, and supplier standards like codes of conduct. Companies with structured data and clear processes can reuse much of this across both assessments.
• Different evaluation logic: EcoVadis assesses whether robust management systems exist and are backed by documented evidence. CDP assesses how well those systems translate into measurable environmental performance, risk management, and forward-looking strategy.
• The “one-two punch”: A strong EcoVadis score indicates that the right structures and controls are in place. A strong CDP score shows that these structures are delivering credible, data-backed outcomes.

Taken together, they provide a more complete view of ESG performance, covering both the strength of internal systems and the results those systems produce.

When to use CDP, EcoVadis, or both

For most companies, the decision to use CDP, EcoVadis, or both depends on which stakeholders they need to address and what type of information is being requested.

Use CDP when environmental transparency is required

CDP is most relevant when companies need to provide structured environmental disclosure to external stakeholders. This includes responding to investor requests, preparing for regulatory reporting such as CSRD, communicating climate risk and strategy, and benchmarking environmental performance.

It is particularly relevant for larger organisations, listed companies, or businesses with significant environmental exposure.

Use EcoVadis when responding to customer and procurement requirements

EcoVadis is most relevant in a commercial context, where sustainability performance needs to be demonstrated to customers. This includes supplier onboarding, RFPs and tenders, and ongoing vendor evaluations. It is especially common in global value chains and B2B environments. In addition to responding to customer requests, many companies use EcoVadis proactively to benchmark ESG maturity and strengthen internal supplier management processes.

Use both when expectations come from multiple stakeholders

Many companies face expectations from investors, regulators and customers. This requires both transparency and operational validation.

In this context, CDP supports comparability and transparency on environmental risks and performance, while EcoVadis demonstrates that robust ESG management systems are in place within operations and across the value chain.
Used together, they provide a more complete picture, covering both disclosure and execution, and allow companies to address a broader range of stakeholder expectations.

Conclusion: build once, respond consistently

The challenge is not choosing between CDP and EcoVadis, but managing both efficiently without duplicating effort.
Leading companies address this by building a single, structured ESG foundation: one set of data, aligned governance, and documented processes that can be reused across frameworks. CDP and EcoVadis then become different expressions of the same underlying system. CDP draws out depth in environmental performance, risk, and strategy, while EcoVadis tests whether robust controls and processes are in place across ESG. Both require tailoring, but neither should require starting from scratch.
This approach is also how companies avoid survey fatigue. Instead of reacting to each request, they respond consistently from a shared foundation.

For many companies, maintaining a CDP Leadership score or an EcoVadis medal is a condition for staying in key customer supply chains. These ratings are embedded in procurement decisions and can directly influence revenue and retention.
Done well, a structured approach ensures companies can meet these expectations consistently. It aligns what they report, how they operate, and how they are evaluated, strengthening credibility with both investors and customers while protecting commercial relationships.
