In today’s global supply chain, customers demand more than just quality products—they expect comprehensive sustainability data. As transparency becomes a non-negotiable requirement, your company will likely need to report sustainability metrics through frameworks like EcoVadis and CDP.
These frameworks are critical for the procurement and supply chain teams of your biggest customers as they help them benchmark their supplier’s performance using consistent scoring systems and mitigate sustainability-related supply chain risks. At Good.Lab, we encourage companies to report to both CDP and EcoVadis, though some customers may only ask them to report to one. As more companies are being asked to report to both, streamlining the process can simplify their work and make their sustainability efforts more efficient.
Read on for actionable insights into fielding reporting requests from EcoVadis and CDP, along with key differences and commonalities and tips on how to best prepare to report to these and other voluntary and mandatory sustainability frameworks.
Key Takeaways
EcoVadis and CDP are the two most common platforms for supplier sustainability performance ratings.
Suppliers can find reporting efficiencies by understanding the differences and commonalities between these two reporting frameworks.
Suppliers can leverage existing environmental data to simplify reporting across both platforms.
EcoVadis takes a more holistic approach to sustainability compared to CDP’s environmental focus.
Reporting through these two frameworks also makes it more efficient to comply with other regulatory and voluntary sustainability standards.
Understanding EcoVadis: The Leading Sustainability Rating Framework
EcoVadis is a leading sustainability reporting framework and performance rating system trusted by over 140,000 companies worldwide. It is widely used by large organizations to request sustainability data from their suppliers, with more than 1,300 global enterprises seeking data from tens of thousands of suppliers annually to ensure alignment with their overall corporate sustainability goals and meet those goals.
Companies asked to report must complete a comprehensive sustainability questionnaire and provide supporting documentation. Based on this input, they receive an annual score on a scale of 1 to 100. Companies scoring in the top 50% earn bronze, silver, gold, or platinum medals, highlighting their sustainability achievements.
EcoVadis assessments holistically cover environmental, social, and governance (ESG) topics, making it a valuable tool for companies to assess the sustainability performance of their suppliers across a wide range of metrics.
Reporters to EcoVadis receive in-depth guidance based on their submissions to improve their future scores and overall sustainability performance. Working with a third party to evaluate this feedback and integrate it with your sustainability strategy can ensure you achieve improved scores year over year.

Understanding CDP: The Leading Environmental Disclosure Framework
Much like EcoVadis, CDP is another leading voluntary framework for sustainability reporting, with over 23,000 companies participating in 2023. It is one of the most commonly used frameworks for companies requesting environmental data from their suppliers, with around 75,000 companies expected to receive data requests in 2024.
Companies and investors use CDP to assess the environmental impact of their suppliers and portfolio companies. Companies request CDP data to ensure suppliers align with their environmental goals and to evaluate climate and other environmental risks in their supply chain.
If asked to report to CDP, you’ll typically receive an invitation to complete an annual questionnaire focused on the metrics your customer wants to know, typically climate data. The questionnaire is submitted during a designated annual reporting period. The questionnaire gauges performance in areas such as climate change, water, and deforestation. Some organizations are scored on an A-F scale, reflecting their environmental performance. CDP reporting is highly regarded for its specific focus on environmental factors and alignment with widely recognized standards like ISSB, TCFD, and SBTi and is therefore favored by sustainability, compliance, and supply chain professionals alike

Why You Might Be Asked to Report to CDP and EcoVadis
Some large buying organizations, like Walmart, Colgate Palmolive, and Astra Zeneca, use both EcoVadis and CDP to get comprehensive insights into the sustainability practices of companies they do business with. While CDP primarily focuses on environmental impacts, EcoVadis provides a broader assessment across all ESG topics. Another reason you might be asked to complete both is if you have one customer who uses EcoVadis and another who requests data through CDP.
Reporting to both frameworks enables your company to report on sustainability holistically and receive scores from both, meeting the expectations of all stakeholders. Additional benefits of reporting to both CDP & EcoVadis include:
Regulatory Preparedness: Improves your ability to collect, measure, and report on key sustainability metrics, which are increasingly essential as sustainability reporting regulations accelerate globally.
Identify Gaps and Improve Sustainability Performance: Reporting to both frameworks allows companies to identify and address gaps in their sustainability practices and drive continuous improvement in areas like emissions reductions.
Improve Brand Reputation: By reporting to and getting scores in both CDP and EcoVadis, a company can demonstrate leadership in sustainability and set itself apart in a competitive, sustainability-conscious market.
CDP vs. EcoVadis: Key Differences Between the Leading Two Sustainability Frameworks
Understanding the differences between CDP vs. EcoVadis helps suppliers align their sustainability reporting efforts with what their largest customers are asking of them. The following table summarizes the main differences between these frameworks:
CDP
EcoVadis
Focus
Climate, water, deforestation, and other environmental factors
Full ESG spectrum, covering environment, labor & human rights, ethics, and sustainable procurement
Methodology
Uses standardized questionnaire focused on environmental metrics
Customized questionnaires tailored to industry, size, and location, spanning four sustainability themes
Reporting
Offers public or private annual reports
Primarily private reports shared with businesses, with public reporting optional
Audience
Primarily utilized by investors, companies, policymakers, and public stakeholders who want deeper insights deeper insights into environmental metrics.
Preferred by procurement and supply chain professionals due to its numeric scoring system and risk mitigation focus.
Benefits
Limited to environmental focus; costly and complex questionnaires; lacks feedback for improvement
Recognized across ESG domains; offers actionable feedback to improve performance
Limitations
Limited to environmental focus; costly and complex questionnaires; lacks feedback for improvement
Limited transparency and verification; less depth on environmental issues; minimal integration with external frameworks
Scoring
Graded A-F based on environmental performance
Primarily private reports shared with businesses, with public reporting optional.
CDP vs. EcoVadis: Commonalities in Sustainability Reporting
For suppliers that are getting asked to report to both, the good news is there are a lot of other overlaps and similarities between the two frameworks and efficiencies to harness
Reuse of Environmental Data: Although CDP only provides a framework for environmental disclosures, those environmental disclosures make up a substantial percentage of EcoVadis reporting. So, the climate, water, deforestation, biodiversity, and plastic data used in CDP reporting can be re-used and will give you much of the data you need to report to EcoVadis and vice versa.
Scores Relating to Improved Performance: In addition to the data reusability part, you can also improve your score with both if you improve sustainability performance over time. Reduce waste, emissions, links to deforestation, and water use, and report that to both, and you will receive an improved score from both.
CDP and EcoVadis Partnership: CDP and EcoVadis are not competitors. The EcoVadis platform is a global Gold Software Solution Provider for CDP. This means that any data reported through EcoVadis can be quite easily re-used to report to CDP. Both consider their frameworks as mutually beneficial to their shared customers.
These overlapping qualities of both frameworks mean that whenever you report to one, if a customer requests you to report to another, there are efficiencies and parallels, which reduce the difficulties of reporting to both.
CDP and EcoVadis Overlaps and Integration with Other Frameworks
The data collected for EcoVadis and CDP reporting will also help you on the way to reporting with every other mandatory and voluntary reporting framework.
Additionally, CDP integrates or is interoperable with many existing frameworks. This means reporting through CDP makes it easy to report to the environmental parts of other frameworks, like the ISSB and ESRS. The following major reporting frameworks and standards are integrated with CDP:
TCFD (Taskforce on Climate-Related Financial Disclosures): In 2018, CDP aligned over 25 of its questions with the Taskforce on Climate-related Financial Disclosures (TCFD) reporting standard, making it the most TCFD-aligned environmental data reporting framework.
TNFD (Taskforce on Nature-Related Financial Disclosures): In 2024, CDP integrated the guidance of the TNFD into the biodiversity section of its reporting questionnaire.
ISSB (international Sustainability Standards Board): In 2023, the ISSB released its first two reporting standards and took over the TCFD’s responsibilities. The following year (2024), CDP integrated the ISSB’s climate-related standards IFRS 2 into its questionnaire.
SBTi (Science Based Targets Initiative): CDP encourages reporters to set their targets through the Science Based Target Initiative (SBTi), has questions based on whether they do, and rewards those who do with improved scores.
GRI (Global Reporting Initiative): CDP works closely with the Global Reporting Initiative (GRI) to align disclosure best practices and avoid duplicative reporting.
While these integrations with CDP prepare suppliers to easily report to these other frameworks, reporting to EcoVadis will also contribute toward reporting with them, albeit to a lesser extent. How Good.Lab Helps Companies Report into CDP & EcoVadis
