EcoVadis vs CDP: Key Differences Explained

Quick Comparison

What is EcoVadis?

EcoVadis is a sustainability ratings platform founded in 2007 that assesses companies on their environmental practices, labor and human rights, ethics, and sustainable procurement. The platform was designed specifically for supply chain sustainability management—helping buying organizations evaluate and monitor the ESG performance of their suppliers.

The assessment methodology uses a combination of company-submitted documentation, 360-degree monitoring (media, NGO reports, government data), and expert analysis by EcoVadis's team of sustainability analysts. Companies receive a scorecard rating from 0-100 across four themes: Environment, Labor & Human Rights, Ethics, and Sustainable Procurement. Scores translate into medal levels—since January 2024, Platinum (top 1%), Gold (top 5%), Silver (top 15%), and Bronze (top 35%), with a minimum score of 30 in each theme—that serve as a quick signal for procurement decisions.

EcoVadis has achieved remarkable scale in the supply chain space. More than 150,000 companies have been rated, and major multinationals including Johnson & Johnson, L'Oréal, Unilever, and BASF use EcoVadis as part of their supplier qualification processes. For many mid-market and small companies, an EcoVadis rating is their first formal sustainability assessment—requested by a customer, not adopted voluntarily.

What is CDP?

CDP (formerly the Carbon Disclosure Project) is a nonprofit organization founded in 2000 that runs the world's leading environmental disclosure system. CDP collects self-reported data from companies, cities, states, and regions on climate change, water security, and forests through detailed annual questionnaires. The data is then scored, published, and made available to investors and purchasing organizations.

Since 2024, companies answer a single integrated CDP questionnaire instead of separate climate change, water security, and forests questionnaires. Its climate questions are among the most detailed corporate climate disclosure requests in use, covering governance, risks and opportunities, business strategy, targets and performance, emissions data (Scope 1, 2, and 3), and verification practices. The water and forests questions go into similar depth in their respective domains. Companies receive letter grades from A (Leadership) to D- (Disclosure), with F assigned to companies that fail to respond to requests.

CDP's influence stems from its institutional backing. In the 2026 disclosure cycle, more than 540 financial institutions with over $110 trillion in assets asked companies to disclose through CDP. The CDP Supply Chain program, with 270+ member companies, requests disclosures from suppliers. Since 2024, CDP's climate questions have used the ISSB's climate standard (IFRS S2), which builds on the TCFD recommendations, as their baseline, making CDP a de facto compliance preparation tool for mandatory climate disclosure requirements.

Key Differences

1. Thematic Breadth vs. Environmental Depth. EcoVadis covers four sustainability themes—environment, labor, ethics, procurement—giving a holistic picture of supply chain sustainability. CDP goes deep on three environmental topics—climate, water, forests—providing granular data that EcoVadis doesn't match on emissions methodology, science-based targets, or resource-specific risk assessment.

2. Primary Use Case. EcoVadis is a procurement tool. Its core value proposition is helping buying companies assess supplier sustainability and manage supply chain risk. CDP is a disclosure and transparency platform. Its core value proposition is giving investors and stakeholders access to standardized environmental data for capital allocation and engagement decisions.

3. Company Size and Accessibility. EcoVadis is designed to be accessible to small and mid-sized companies that may lack dedicated sustainability teams. The questionnaire adapts to company size and industry. CDP's questionnaire is substantial—the full corporate version runs to 13 modules—requiring significant data collection capacity. This creates a natural bias toward larger, more resourced companies, though CDP introduced a shorter SME questionnaire in 2024.

4. Scoring Methodology. EcoVadis scores reflect the quality of a company's sustainability management system—policies, actions, and results—relative to industry and size peers. CDP scores measure the quality and completeness of environmental disclosure and the ambition of environmental management. A company could score well on EcoVadis with strong management systems but score poorly on CDP if its climate disclosures lack granularity, and vice versa.

5. Transparency of Results. CDP scores are publicly available—anyone can look up a company's climate, water, or forest grade on CDP's website. EcoVadis scores are shared only between the rated company and requesting buyers, unless the company opts to publish its scorecard. This makes CDP a public accountability tool and EcoVadis a private supply chain management tool.

6. Cost Model. Companies pay for their EcoVadis assessment through an annual subscription priced by company size and plan. CDP disclosure is not free either: disclosing companies, including SMEs, pay CDP an administrative fee, and CDP also funds itself through grants, memberships, and data sales. EcoVadis assessments are typically triggered by buyer requests that justify the cost, while CDP disclosure is usually prompted by investor or customer requests, though companies can also disclose on their own initiative.

Which One Do You Need?

If your customers are requesting sustainability evidence as part of procurement qualification, EcoVadis is likely your first priority. It's one of the most widely used supply chain sustainability platforms, and an EcoVadis medal has become a procurement prerequisite for many multinationals. The assessment is manageable for companies without dedicated sustainability teams.

If your investors, lenders, or major customers are requesting climate and environmental disclosures, CDP is essential. CDP's A-List carries significant reputational value, and the data collection process prepares you for mandatory climate reporting under the CSRD and ISSB-based rules. If you're a significant emitter or operate in water-stressed or deforestation-linked sectors, CDP provides the most recognized disclosure platform.

Many companies end up doing both. The data overlaps—environmental management information submitted to EcoVadis can inform CDP responses, and vice versa. Smart sustainability teams build a single data collection infrastructure that feeds both platforms, avoiding duplication and ensuring consistency across disclosures.

Council Fire's Perspective

EcoVadis and CDP serve different masters—procurement and investors, respectively—but together they provide the most comprehensive external validation of a company's sustainability credentials. We advise clients to understand which platform their stakeholders are actually looking at and prioritize accordingly, rather than treating all ratings as equally important.

The strategic insight is that EcoVadis tells the story of how well you manage sustainability across your operations, while CDP tells the story of how transparently and ambitiously you address environmental challenges. Companies that score well on both are demonstrating both management quality and environmental leadership—exactly the combination that sophisticated buyers and investors want to see.

Frequently Asked Questions

Can I use my EcoVadis data for CDP, or vice versa?

There's significant data overlap, particularly on environmental management, energy use, and emissions. However, the formats and depth requirements differ substantially. CDP requires much more granular emissions data (Scope 1, 2, 3 by category), science-based target details, and scenario analysis that EcoVadis doesn't ask for. EcoVadis covers labor, ethics, and procurement topics that CDP doesn't address. Build your data collection once and map it to both platforms rather than starting from scratch for each.

Which rating matters more for ESG investors?

CDP carries more weight with institutional investors: in the 2026 cycle, more than 540 financial institutions with over $110 trillion in assets requested disclosure through CDP. EcoVadis is more influential with procurement-focused stakeholders and supply chain partners. If you're seeking investment, prioritize CDP. If you're seeking commercial contracts, prioritize EcoVadis.

How long does each assessment take to complete?

EcoVadis gives companies a default 30 business days to submit the questionnaire, and results typically publish 6 to 8 weeks after submission. The platform is designed for efficient completion, with tailored questionnaires based on industry and size. CDP responses usually take several months of data collection and preparation, particularly the climate questions, which demand detailed emissions inventories, scenario analysis, and governance documentation. First-time respondents should allow additional time for both platforms.

Is there an advantage to scoring well on both platforms simultaneously?

Yes. Companies that achieve EcoVadis Gold or Platinum alongside CDP A or A- status demonstrate comprehensive sustainability leadership to both procurement and investor audiences. Some procurement programs accept CDP scores alongside or in lieu of EcoVadis, and vice versa. Increasingly, RFP processes and investment screens check both platforms, making dual high performance a competitive differentiator.
