How Vodafone uses Nossa Data to achieve EcoVadis Platinum and the CDP A-list

About Vodafone: Vodafone Group Plc is one of the world’s leading telecommunications companies, operating across Europe and Africa. Beyond enabling connectivity, Vodafone addresses ESG issues through their purpose-driven strategy and seeks to enable an inclusive, sustainable and trusted digital society. As part of Vodafone’s ambition to lead in sustainability and transparency, the group discloses its ESG information voluntarily to a number of the market’s key sustainability frameworks, standards, and benchmarks including the CDP, EcoVadis, GRI, SASB, TCFD, and WBA’s benchmarks.

In 2025, Vodafone achieved a Platinum medal in the EcoVadis sustainability assessment for its second year in a row. On top of this, Vodafone made the CDP A-list for the 2025 questionnaire for the climate change theme in early January this year. Using Nossa Data’s ESG reporting tool, Vodafone was able to improve its process for responding to the two major sustainability questionnaires.

About Nossa Data: Nossa Data is a female-founded ESG technology and advisory company that works with many of the world’s largest companies. The easy to use software streamlines ESG disclosures across global regulatory reporting: CSRD, IFRS as well as voluntary reporting: CDP, Ecovadis, SASB and more. The software also uses AI to further streamline reporting for companies improving both the quality of their disclosure and the efficiency of disclosure. 

EcoVadis and CDP

The EcoVadis Sustainability questionnaire assesses companies on their environmental, social and ethical performance and it's an important disclosure practice for procurement. Vodafone leverages its EcoVadis rating to demonstrate to stakeholders across its supply chain, their commitment and management of sustainability risks. Achieving an Ecovadis Platinum rating is a strong achievement as it places the company at the top 1% of organisations assessed globally. 

The CDP corporate questionnaire is the leading framework for climate disclosure. Through participation in the annual CDP cycle, companies demonstrate to hundreds of capital market signatories their commitment to tackling climate-related risks and opportunities. In 2025, over 22,100 companies disclosed their data through CDP, representing more than half of global market capitalisation. The CDP A-list represents the top 4% of nearly 20,000 assessed companies

Challenge

Key challenges included:

• Sustainability information spread across multiple teams: Both EcoVadis and CDP questionnaires require input from numerous stakeholders, each responsible for different sections and subject-matter areas.
• Evidence-heavy reporting requirements: EcoVadis in particular requires extensive supporting documentation. Vodafone needed a way to discuss, draft, and validate evidence collaboratively before final submission.
• Complex question guidance: Both frameworks provide detailed guidance that must be interpreted correctly to ensure responses are relevant, complete, and score well.
• Time-consuming information retrieval: Much of the information required for these disclosures already existed in public or internal documents, but contributors spent significant time searching, extracting, and adapting content for each question.

Solution

Vodafone used Nossa Data to centralise and streamline its EcoVadis and CDP reporting processes. Olivia Davies, ESG Data Insights and Disclosures Manager at Vodafone shares: 

“Using Nossa Data has streamlined our approach to voluntary ESG reporting. By centralising collaboration, clarifying requirements and improving both our internal audit trail and review process, the platform has enhanced both the efficiency and consistency of our CDP and EcoVadis submissions. This has supported Vodafone in delivering complete, accurate and high-quality ESG disclosures aligned with our ambition to drive transparent and trusted reporting.”

Nossa Data enabled Vodafone to:

• Collaborate across teams in one platform: Multiple users could access the relevant report templates, work in parallel, comment directly within questions, and reassign sections as needed—eliminating fragmented workflows and version control issues.
• Draft and review evidence collaboratively: Contributors could add comments, upload documents, and discuss potential evidence directly within the questionnaire, supporting EcoVadis’ evidence-driven approach.
• Access clear, in-platform question guidance: Nossa Data surfaced EcoVadis and CDP guidance alongside each question, helping users understand expectations and align responses to scoring criteria.
• Leverage AI-suggested materials: The platform scanned both public and private documents (depending on the questionnaire) and matched relevant content to specific questions. This significantly reduced time spent searching for information and allowed contributors to focus on refining and strengthening responses.

The results: More efficient, higher-quality sustainability disclosures

By using Nossa Data, Vodafone transformed how it approaches voluntary sustainability reporting:

• Reduced reporting effort: Automated document matching and AI-assisted content suggestions cut down the time required to locate and draft responses.
• Improved collaboration and consistency: A single platform enabled clearer ownership, smoother handovers, and better alignment across teams.
• Stronger, evidence-based submissions: In-context discussions and document management supported higher-quality responses, particularly for EcoVadis’ evidence-heavy assessment.
• Greater confidence in disclosures: With guidance and content support embedded directly into the workflow, Vodafone could respond more confidently to both EcoVadis and CDP requirements.

As expectations around voluntary sustainability disclosures continue to rise, Nossa Data has provided Vodafone with a scalable, efficient foundation for producing high-quality, stakeholder-ready responses year after year.
