CDP scores have become procurement currency. Global brands use them to rank suppliers, investors use them to screen portfolios, and a weak score quietly costs manufacturers business they never see lost. Scoring well is less about writing polished prose and more about the data infrastructure behind every answer.
This guide explains how CDP scoring works, what distinguishes A-list performers, and how Asian manufacturers can climb from disclosure to leadership without drowning their teams in questionnaire season.

If you manage sustainability for a manufacturing company in Asia, the chances are that CDP has already appeared on your radar. Perhaps an investor requested that you disclose. Perhaps a key customer in Europe or North America asked for your CDP score as part of their supplier assessment. Or perhaps your board has simply noted that competitors in your sector are achieving A-list recognition and wants to understand what that requires.
CDP, formerly known as the Carbon Disclosure Project, is the world’s largest environmental disclosure platform. Each year, CDP asks thousands of companies to report on their environmental performance through standardised questionnaires covering three themes: climate change, water security, and forests. The responses are scored on a scale from A to D-, and the results are made available to investors, supply chain partners, and the public.
The scale of CDP reporting is substantial. Over 23,000 companies disclose through CDP globally, representing more than two-thirds of global market capitalisation. Behind these disclosures are over 680 institutional investors with more than USD 130 trillion in assets under management, and over 280 large purchasing organisations that use CDP data to evaluate their supply chains.
For manufacturers in Singapore, Taiwan, Thailand, Indonesia, and Malaysia, CDP reporting has moved from a voluntary nicety to a commercial imperative. The reasons are straightforward.
First, global supply chain pressure is intensifying. Multinational corporations across the semiconductor, electronics, automotive, and consumer goods sectors are using CDP scores as a screening criterion for supplier selection. If your company cannot provide a credible CDP response, you risk being excluded from preferred supplier programmes and losing access to major customers.
Second, institutional investors increasingly use CDP data as part of their investment analysis. If your company is listed on SGX, the Taiwan Stock Exchange, or SET, or if you are considering an IPO or seeking private equity investment, your CDP score is one of the data points that investors will examine. A strong score signals that your company takes environmental risk management seriously. A weak score, or no response at all, raises questions about the quality of your environmental governance.
Third, CDP reporting creates a structured framework for understanding and managing your environmental impacts. Even if no one were looking at your answers, the process of completing a CDP questionnaire forces your organisation to examine its carbon emissions, water use, and commodity sourcing with a level of rigour that most companies would not otherwise apply. This process often reveals risks and opportunities that were previously hidden.
For CFOs, the financial implications are clear. CDP scores influence access to capital, supply chain positioning, and insurance terms. For CSOs and Sustainability Managers, CDP reporting provides a globally recognised platform for demonstrating the value of your work. For Operations Directors, it creates a connection between environmental performance and operational efficiency that can drive measurable cost savings.
CDP operates three separate questionnaires, each addressing a distinct environmental theme:
Each questionnaire is scored independently. A company can respond to one, two, or all three, depending on which themes are most material to its operations. Most manufacturers begin with the Climate Change questionnaire and expand to Water and Forests as their disclosure programmes mature.
| Score Band | What It Signals | Typical Evidence Base |
|---|---|---|
| D to C | Disclosure level: answered but weak | Partial data, estimates, no verification |
| B | Management level: processes exist | Complete inventory, governance in place |
| A to A- | Leadership level: best practice | Verified data, science-based targets, risks in strategy |
One of the most common questions we hear from companies new to CDP reporting is: “What does it actually take to get an A?” The answer requires an understanding of how CDP evaluates responses.
CDP scores companies across four progressive levels. Each level builds on the one below it, which means that a company cannot achieve a Management-level score without first demonstrating Disclosure, and cannot achieve Leadership without first demonstrating Management.
The Disclosure level assesses whether a company has provided the basic information requested by the questionnaire. This includes reporting Scope 1 and Scope 2 greenhouse gas emissions, disclosing energy consumption, identifying climate-related risks and opportunities, and providing basic governance information such as board-level oversight of environmental issues.
A Disclosure-level score (D or D-) indicates that a company has submitted a response but with significant gaps. Many companies in Asia receive a Disclosure score in their first year, simply because they have not previously collected the data that CDP requests.
The Awareness level evaluates whether a company demonstrates a genuine understanding of its environmental impacts and how they relate to its business strategy. This means going beyond data reporting to show that the company has assessed its risks, considered the implications of different climate scenarios, and identified the most significant environmental issues for its operations.
An Awareness-level score (C or C-) indicates that a company is thinking about environmental issues in a structured way but has not yet translated that thinking into systematic action. This is where many Asian manufacturers find themselves after two or three years of CDP reporting.
The Management level assesses whether a company has implemented concrete policies, processes, and targets to address its environmental impacts. This includes setting emissions reduction targets, implementing energy management systems, establishing water stewardship programmes, integrating environmental considerations into procurement decisions, and reporting progress against commitments.
A Management-level score (B) indicates that a company has moved from awareness to action. It has the systems and governance structures in place to manage its environmental impacts, and it can demonstrate progress over time. For most manufacturers, reaching Management level is a significant achievement that reflects genuine organisational commitment.
The Leadership level, corresponding to an A or A- score, is reserved for companies that demonstrate best practice in environmental management. This requires not only comprehensive disclosure and robust management practices, but also evidence of verified emissions data, science-based targets, integration of environmental strategy into business planning, and measurable outcomes.
Companies on the CDP A List represent approximately the top 2% to 3% of respondents globally. They are recognised as leaders in environmental transparency and action, and their scores are widely cited by investors, customers, and media as evidence of corporate responsibility.
The scoring methodology applies consistently across all three questionnaires, though the specific criteria differ to reflect the distinct nature of climate, water, and forest issues. The common thread is that CDP rewards completeness, transparency, evidence of action, and third-party verification.
Understanding this structure is essential for planning your CDP reporting strategy. If you are currently at Disclosure or Awareness level, the most efficient path to a higher score is not to focus on any single question, but to systematically address the gaps that prevent you from progressing to the next level.

CDP reporting is the process of disclosing environmental data through the CDP (formerly Carbon Disclosure Project) questionnaire system. Companies respond to questionnaires covering climate change, water security, and forests, and receive a score from A to D- based on the completeness and quality of their disclosure. Over 23,000 companies worldwide disclose through CDP, making it one of the most widely recognised environmental disclosure platforms.
CDP scores are calculated based on four levels of disclosure: Disclosure (providing information), Awareness (understanding environmental issues), Management (taking action through policies and processes), and Leadership (demonstrating best practice and verification). Companies receive scores ranging from A (Leadership) to D- (No disclosure). The scoring methodology assesses the completeness, accuracy, and ambition of a company’s environmental disclosures across its operations and value chain.
Manufacturers can improve their CDP score by ensuring complete disclosure of all requested data, implementing verified carbon accounting systems, setting science-based targets, obtaining third-party assurance for emissions data, and demonstrating concrete governance structures for environmental management. Using carbon accounting software such as NxMap can streamline data collection and produce audit-ready reports that satisfy CDP requirements, potentially reducing reporting time by up to 80%.
CDP reporting is voluntary in most jurisdictions, but many manufacturers respond to CDP questionnaires because their investors, customers, or supply chain partners request it. Over 680 institutional investors and 280 large purchasing organisations use CDP data to make decisions. In practice, if your company supplies to multinational corporations or seeks institutional investment, CDP reporting has become a commercial requirement rather than a purely voluntary exercise.
CDP has aligned its questionnaires with the ISSB standards (IFRS S1 and S2) and the EU’s CSRD framework. Companies that complete CDP disclosures are simultaneously generating much of the data required for ISSB-aligned reporting. The CDP climate change questionnaire incorporates TCFD recommendations, which form the basis of ISSB S2. This alignment means that a well-prepared CDP response can serve as a foundation for meeting multiple regulatory requirements simultaneously.
The CDP Climate Change questionnaire focuses on greenhouse gas emissions (Scope 1, 2, and 3), climate risks and opportunities, transition plans, and energy management. The CDP Water Security questionnaire addresses water withdrawal, consumption, discharge, water-related risks, and watershed stewardship. The CDP Forests questionnaire covers commodity sourcing linked to deforestation, including timber, palm oil, soy, cattle, and rubber. Each questionnaire is scored independently, and companies can respond to one, two, or all three depending on their material environmental impacts.
First-time responders typically spend two to four months gathering data and coordinating responses across sustainability, finance, procurement, and operations teams. Companies with automated carbon data platforms compress this to weeks because activity data, emission factors, and methodologies are already centralised and traceable. The effort is front-loaded: year one builds the foundation, subsequent years are largely updates.
Three audiences dominate: major customers who request disclosure through CDP Supply Chain and factor scores into procurement decisions, investors screening portfolio companies through CDP Investor initiatives, and increasingly lenders assessing climate risk. A poor or missing score can quietly exclude a supplier from tender shortlists without any explicit rejection.
Yes, CDP questions align closely with TCFD structure and increasingly reference ISSB standards, so a well-evidenced CDP response doubles as raw material for ISSB-aligned disclosures and customer questionnaires. The verified emissions data behind a strong CDP answer is the same data SGX reporting, SBTi tracking, and green loan applications require.
Yes, companies can initiate disclosure voluntarily through the CDP portal without a customer or investor request. Unrequested disclosure is a common strategy for suppliers anticipating future procurement requirements, because the first response establishes a baseline score and reveals data gaps while there is still time to fix them.
