The Carbon Disclosure Project, now officially known simply as CDP, is an international non-profit organization that has established a global system for investors, companies, cities, states, and regions to manage their environmental impacts.
At its core, the CDP acts as a centralized platform for environmental disclosure, compelling organizations to measure, understand, and transparently share vital data related to climate change, water security, and deforestation. This process transforms environmental performance from an abstract concept into a tangible, comparable, and actionable metric for the global market.
The profound importance of the CDP stems from its unique ability to channel the power of investor and customer pressure to catalyze corporate environmental responsibility, making it a cornerstone of modern sustainable finance and corporate governance.
The CDP’s model is powerfully simple: it represents a growing coalition of institutional investors with trillions of dollars in assets who request environmental data from thousands of organizations worldwide.
This request-for-information creates a standardized dataset that allows for apples-to-apples comparisons across industries and geographies. The disclosed information is not buried in obscure reports; it is scored and made publicly available, creating a powerful driver for performance improvement.
Companies strive for better scores to attract investment, secure customer contracts, and protect their brand reputation. The CDP has effectively created a universal language for corporate environmental transparency, which is now a critical component of risk management and long-term business resilience.
Key Established Facts about the CDP:
✔️ CDP holds the largest and most comprehensive global repository of self-reported environmental data in the world.
✔️ It is backed by a vast network of over 700 financial institutions with more than $130 trillion in assets.
✔️ Thousands of organizations, including the vast majority of the world’s largest corporations, disclose through CDP annually.
✔️ The CDP scoring system is widely recognized as the gold standard for corporate environmental transparency.
✔️ CDP’s framework is fully aligned with the Task Force on Climate-related Financial Disclosures (TCFD) recommendations.
The CDP was founded with a visionary goal: to make environmental reporting and risk management a standard business practice. The journey began when a group of investors recognized that they lacked consistent data to assess the climate-related risks in their portfolios.
In response, they sent a joint request for information to global companies, laying the foundation for what would become the CDP. This initiative demonstrated that collective investor pressure could be a potent force for change, compelling companies to start measuring and disclosing their carbon emissions.
The organization’s core mission has remained steadfast: to transform the global economic system to prevent dangerous climate change and protect our planet’s natural resources by putting relevant environmental information at the heart of business, investment, and policy decisions.
The evolution of the CDP from a small project focused solely on carbon to a comprehensive environmental reporting platform mirrors the expanding understanding of ecological crises. It initially concentrated on carbon dioxide emissions but soon expanded its scope to encompass a full corporate carbon footprint, and later, other critical environmental domains.
Today, the CDP’s mission is executed through its annual disclosure cycles, which collect data on climate change, water security, and forests.
By providing a clear and structured framework, the CDP enables organizations to not only report on their impacts but also to identify risks and opportunities, set ambitious reduction targets, and track their progress over time, thereby embedding environmental accountability into their strategic core.
In today’s business landscape, CDP disclosure has shifted from a voluntary “nice-to-have” to an essential component of corporate strategy and credibility. Several powerful macroeconomic and social forces are converging to make CDP participation non-negotiable for serious players in the global market.
First and foremost is the immense pressure from the financial sector. Investors and lenders increasingly view strong environmental performance as a proxy for sound, forward-thinking management and a reduced risk profile.
A high CDP score signals to the market that a company is well-prepared for the transition to a low-carbon economy and is proactively managing regulatory, physical, and reputational risks associated with climate change and resource scarcity.
Beyond investor demand, regulatory pressures are mounting globally. Governments and regulatory bodies are increasingly mandating climate-related disclosures, often drawing directly from the CDP framework and the TCFD recommendations.
By participating in CDP now, companies future-proof their operations against impending regulations. Furthermore, supply chain pressures are immense; large multinational corporations are now requiring their suppliers to disclose through CDP as a condition for doing business.
This cascading effect means that even small and medium-sized enterprises must engage with CDP to remain competitive. Finally, consumer and employee expectations are higher than ever.
A transparent sustainability record, validated by a third party like CDP, is a powerful tool for attracting top talent and building brand loyalty in an increasingly conscious marketplace.
The CDP framework is a meticulously designed questionnaire that guides organizations through the process of disclosing their environmental management, impacts, risks, and opportunities. It is structured around three core environmental themes: Climate Change, Water Security, and Forests.
Each questionnaire is tailored to specific sectors, ensuring the questions are relevant and impactful for different industries. The process is annual, creating a consistent time series of data that allows organizations and stakeholders to track progress.
Completing the CDP questionnaire forces a company to take a holistic look at its environmental footprint, engaging various departments from operations and finance to risk management and the C-suite, thereby fostering internal awareness and accountability.
The output of this disclosure is not just a data dump; it is a comprehensive public scorecard. The CDP scoring system is a robust methodology that assesses the completeness and quality of a company’s disclosure, as well as its level of environmental awareness and management.
The scores, which range from A to D- with an ‘F’ for failure to disclose, provide a clear and immediate snapshot of a company’s environmental performance relative to its peers. This transparent grading system creates a powerful competitive dynamic, motivating companies to continuously improve their strategies, actions, and, consequently, their scores year after year.
It is this combination of a detailed framework and a transparent, public scoring mechanism that gives the CDP its unique influence.
The CDP’s comprehensive approach is embodied in its three distinct but interconnected questionnaires. Each questionnaire addresses a critical planetary boundary and is designed to extract detailed, actionable information from disclosing organizations.
The CDP scoring methodology is a multi-stage process that evaluates a company’s response across several dimensions of leadership. Understanding the nuances of this grading system is crucial for any organization aiming to improve its standing.
The scoring is not just about what you have done, but also about how well you have reported it. The methodology specifically assesses:
✔️ Completeness: How thoroughly the company has answered all relevant questions.
✔️ Awareness: The company’s understanding of its environmental impacts.
✔️ Management: The systems and processes in place to address these impacts.
✔️ Leadership: The implementation of best-practice actions and ambitious goals.
A strong CDP performance is far more than a trophy for the sustainability team; it delivers concrete, bottom-line business benefits that enhance a company’s financial value, operational resilience, and competitive positioning.
In an era where environmental performance is increasingly correlated with financial performance, a high CDP score serves as a powerful market signal. It directly addresses the information needs of a wide range of stakeholders, from investors and customers to regulators and employees, providing them with a trusted, third-party validation of the company’s environmental stewardship and long-term viability.
This external validation translates into a multitude of strategic advantages that can accelerate growth and de-risk the business model.
The most immediate benefit is improved access to capital. A strong CDP score demonstrates to investors that the company is proactively managing its environmental risks, which are increasingly seen as material financial risks.
This can lead to a lower cost of capital, as investors perceive the company as a safer, more future-proofed bet. Furthermore, it can unlock dedicated green financing and attract the growing pool of ESG-focused funds.
Beyond finance, a high score enhances brand reputation and customer loyalty. As consumers become more environmentally conscious, they are actively seeking out brands that can prove their green credentials, and a CDP ‘A’ list is one of the most recognized marks of achievement in this space.
Key Business Advantages of a High CDP Score:
✔️ Enhanced Investor Confidence: Provides transparent, comparable data that reduces investment risk.
✔️ Competitive Advantage: Differentiates the company in tenders and B2B relationships, where CDP scores are increasingly used as a pre-qualification criterion.
✔️ Operational Efficiencies: The process of calculating your carbon footprint and assessing risks often uncovers opportunities for cost savings, particularly in energy and resource use.
✔️ Attraction and Retention of Talent: Top talent, especially among younger generations, prefers to work for companies that are demonstrably responsible and purpose-driven.
✔️ Informed Strategic Decision-Making: The CDP process forces a deep, internal analysis that helps leadership make better long-term decisions in the face of climate change and resource constraints.
CDP reporting is a powerful engine for both value creation and risk mitigation, moving beyond simple compliance to become a strategic management tool. On the value creation side, the disciplined process of preparing the CDP response compels a company to systematically identify and quantify climate-related opportunities.
These can include the development of new low-carbon products and services, access to new markets, improvements in resource efficiency that cut costs, and the enhancement of brand value.
For instance, a company might discover through its CDP preparation that by improving the energy efficiency of its operations, it can not only reduce its Scope 1 and 2 emissions but also achieve significant cost savings, directly adding to the bottom line.
On the flip side, CDP reporting is an unparalleled exercise in risk mitigation. The framework requires companies to conduct a thorough assessment of physical risks (e.g., how a factory is vulnerable to flooding) and transition risks (e.g., how new carbon taxes or shifts in consumer preference could impact the business).
By formally identifying, assessing, and disclosing these risks, companies are forced to develop strategies to manage them. This proactive approach prevents costly surprises down the line, ensures business continuity, and reassures investors that the company is not sleepwalking into a crisis.
In essence, the CDP process embeds climate and environmental considerations into the core enterprise risk management framework, making the entire organization more resilient.
A growing body of evidence suggests a strong positive correlation between high CDP scores and superior financial performance. This correlation is logical when considering that the qualities rewarded by a high CDP score—such as robust governance, strategic foresight, operational efficiency, and proactive risk management—are the same qualities that drive long-term financial success.
Companies that score well on CDP are typically better managed overall. They are more likely to have forward-looking leadership teams that understand the megatrends shaping the global economy, including the inevitable transition to a net-zero future.
Studies have shown that companies on the CDP ‘A List’ often outperform their lower-scoring peers on various financial metrics, including stock price performance, return on equity, and dividend growth. This outperformance is driven by several factors.
Firstly, these companies are better positioned to capitalize on the opportunities of the green economy. Secondly, they are less likely to be blindsided by regulatory changes or stranded assets.
Thirdly, their strong reputation makes them more resilient to market volatilities and more attractive to long-term investors. While correlation does not equal causation, the link is compelling enough for the financial community to use CDP data as a key input in their investment decisions and valuations.
The CDP does not operate in a vacuum; it is a central node in a rapidly evolving ecosystem of global sustainability standards and frameworks. Its power is amplified by its deep integration and alignment with other critical initiatives, creating a cohesive and reinforcing system for corporate reporting.
For companies, understanding these interconnections is vital for streamlining their reporting processes and avoiding duplication of effort. By leveraging these synergies, an organization can use a single set of data and analyses to meet multiple reporting requirements, making their sustainability program more efficient and effective.
The CDP has strategically positioned itself as the primary disclosure platform that brings these other frameworks to life through annual, actionable reporting.
The most significant alignment is with the Task Force on Climate-related Financial Disclosures (TCFD). The CDP questionnaire is explicitly built upon the TCFD’s four-pillar structure of Governance, Strategy, Risk Management, and Metrics & Targets.
By responding to CDP, a company is effectively providing a comprehensive TCFD report. This is critically important as TCFD-aligned disclosures are becoming mandatory in an increasing number of jurisdictions.
Furthermore, CDP’s data collection is foundational for other major reporting standards, including the International Sustainability Standards Board (ISSB), the Global Reporting Initiative (GRI), and the corporate standards of the European Sustainability Reporting Standards (ESRS) under the CSRD.
This interconnectedness establishes CDP as a practical, entry-point for companies preparing for a future of mandatory, comprehensive ESG disclosure.
The relationship between CDP and the TCFD is one of deep, strategic partnership and functional integration. The TCFD, created by the Financial Stability Board, developed a conceptual framework for what information companies should disclose regarding climate-related financial risks and opportunities. It provided the structure and the principles.
The CDP, on the other hand, provided the practical mechanism for how to disclose that information. It translated the TCFD’s recommendations into a detailed, sector-specific questionnaire with clear scoring guidance. In essence, the TCFD is the architect, and the CDP is the builder and operator of the disclosure system.
This synergy means that when a company completes the CDP Climate Change questionnaire, it is simultaneously creating a TCFD-aligned report. The CDP’s questions are mapped directly to the TCFD’s pillars:
The Greenhouse Gas (GHG) Protocol is the foundational accounting standard that provides the methodology for calculating a carbon footprint, and the CDP is the primary global platform for disclosing that footprint.
The relationship is symbiotic and essential. The CDP questionnaire mandates the use of the GHG Protocol Corporate Standard to calculate and report emissions. This ensures consistency, accuracy, and comparability of the emissions data disclosed by thousands of companies across the globe.
Without the GHG Protocol, CDP would lack a standardized metric; without CDP, the GHG Protocol data would often remain in internal reports, unseen by investors and the public.
The CDP reporting process rigorously applies the GHG Protocol’s three-scope framework:
Embarking on the CDP reporting journey can seem daunting, but with a structured, methodical approach, it becomes a manageable and highly valuable process. A successful CDP response is not a last-minute effort; it requires careful planning, cross-functional collaboration, and a commitment to data integrity.
The process typically unfolds over several months, aligning with the CDP’s annual reporting cycle which opens in April and closes in July.
Breaking down the journey into clear, sequential phases allows an organization to allocate resources effectively, gather the necessary information, and produce a high-quality submission that accurately reflects its environmental performance and ambitions.
This step-by-step guide provides a roadmap for both first-time disclosers and those looking to improve their scores from previous years.
The ultimate goal is to move beyond viewing CDP as a simple reporting exercise and to instead see it as an annual strategic health check on the company’s environmental management and transition preparedness.
By integrating the CDP process into the core business operations, companies can unlock its full value, using the insights gained to drive innovation, improve efficiency, and build resilience.
For organizations seeking expert guidance, partnering with a provider of ESG Consultancy services can help navigate the complexities of the framework, develop a robust climate strategy, and ensure a disclosure that meets investor-grade expectations.
Preparation is the most critical phase of the CDP journey, laying the groundwork for everything that follows. This phase should begin months before the reporting platform even opens.
Many companies, especially those new to the process, fall into common traps that can lead to a poor score, wasted effort, and reputational damage. Being aware of these pitfalls is the first step toward avoiding them.
✔️ Pitfall 1: Underestimating Scope 3 Emissions. Ignoring or providing a poor-quality Scope 3 inventory is a major red flag for CDP scorers. Since these emissions often represent the largest part of a company’s footprint, a lack of engagement here suggests a failure to understand the full extent of your climate impact.
* Solution: Start by focusing on the most relevant Scope 3 categories. Use industry averages and spend-based data if primary data is unavailable, but have a plan to improve data quality over time.
✔️ Pitfall 2: Vague and Unsubstantiated Claims. Making high-level statements like “we are committed to sustainability” without providing concrete evidence, policies, or tangible actions will not earn points. CDP scoring is evidence-based.
* Solution: Back up every claim with specific examples, data, and references to official company documents. Quantify your actions and outcomes wherever possible.
✔️ Pitfall 3: Poor Governance Disclosure. Simply stating that the board has oversight is insufficient. CDP wants to see the mechanics of that oversight.
* Solution: Clearly describe how often the board discusses climate issues, which committee is responsible, how climate performance is linked to executive remuneration, and how the board is skilled in understanding climate-related risks.
✔️ Pitfall 4: Inadequate Risk and Opportunity Analysis. Listing generic risks without explaining their specific financial impact, time horizon, and magnitude is a common weakness.
* Solution: Use a structured risk matrix. For each risk and opportunity, detail the potential financial impact, the likelihood, and the time horizon (short, medium, long-term). Clearly link them to your business strategy.
✔️ Pitfall 5: Treating it as a One-Off Exercise. The companies that score the worst are those that treat CDP as an annual form-filling chore rather than a reflection of an ongoing, embedded management process.
* Solution: Integrate CDP’s framework into your regular business planning, risk management, and strategic decision-making cycles. The response should be a snapshot of business-as-usual, not a special project. To make this integration seamless, explore Digital Integration Solutions that can embed carbon tracking and management directly into your operational systems.

By leveraging Climefy’s end-to-end solutions, companies can not only produce a high-quality CDP disclosure but also use the insights gained to drive tangible environmental and business outcomes, transforming a reporting obligation into a strategic advantage.
Climefy’s platform aligns perfectly with the core requirements of the CDP framework. It provides the data management backbone needed for accurate GHG accounting across all three scopes, facilitates the risk and opportunity assessments demanded by the TCFD-aligned questionnaire, and supports the target-setting process essential for a strong score.
Furthermore, Climefy’s commitment to integrity and transparency, exemplified by its own Climefy Verified Carbon Standard, ensures that any carbon offsets used in a company’s climate strategy are of the highest quality, which strengthens the credibility of the entire CDP response.
Partnering with Climefy means having a dedicated guide on the path from disclosure to demonstrable action.
The cornerstone of any CDP response is an accurate and comprehensive greenhouse gas (GHG) inventory. Climefy’s tiered carbon calculators are specifically engineered to simplify this foundational step, removing the technical barriers that often hinder organizations, especially small and medium-sized enterprises.
These intuitive digital tools guide users through the process of data collection and emission factor application, ensuring that the resulting carbon footprint is calculated in strict accordance with the GHG Protocol, the very standard mandated by CDP.
This not only saves significant time and resources but also guarantees the data quality necessary for a credible disclosure.
Climefy offers tailored solutions for every type of discloser:
A robust climate strategy, as evaluated by CDP, follows a clear hierarchy: measure, reduce, and then offset. Once a company has measured its footprint and implemented aggressive reduction initiatives, carbon offsetting becomes a critical tool for addressing residual emissions that are currently unavoidable on the path to net-zero.
The CDP recognizes high-quality carbon offsetting as a legitimate and important interim measure, provided it is not used as a substitute for direct emission reductions. This is where the Climefy Marketplace plays a pivotal role.
It provides a trusted venue for companies to invest in verified carbon reduction projects, such as afforestation and plantation or renewable energy, that compensate for their remaining emissions while contributing to sustainable development.
The integrity of this process is paramount. The CDP and other stakeholders are increasingly scrutinizing the quality of carbon credits to avoid greenwashing. The Climefy Marketplace addresses this by listing projects that are rigorously vetted under the Climefy Verified Carbon Standard or other internationally recognized protocols.
This ensures that every ton of CO2 claimed to be offset represents a real, additional, permanent, and independently verified reduction or removal from the atmosphere.
By utilizing the Climefy Marketplace, a company can confidently report its offsetting activities in its CDP response, demonstrating a comprehensive and credible approach to achieving its climate targets and supporting its net zero journey.
The landscape of environmental reporting is complex and constantly evolving. A successful, long-term CDP strategy requires an organization to have deep, internal expertise. The Climefy Sustainability Academy is designed to build this capacity from within.
It offers cutting-edge education and training on all aspects of sustainability, from the fundamentals of carbon accounting and the nuances of the CDP questionnaire to advanced topics like TCFD implementation and net-zero strategy development.
By empowering employees with knowledge, the Academy transforms the CDP process from a centralized, stressful task into a distributed, understood, and integrated business practice.
Investing in education through the Academy yields significant returns. It enables the cross-functional team responsible for CDP to speak a common language and understand the strategic importance of their work.
It equips the finance department to better understand climate-related financial risks, it helps risk managers incorporate environmental factors into their models, and it allows operational staff to identify efficiency opportunities.
An educated team is better equipped to not only complete a high-scoring CDP response but also to implement the climate strategy it describes, turning disclosure into decisive action and lasting competitive advantage.
CDP is a specific, global disclosure system focused on environmental data (Climate, Water, Forests), which is the “E” in ESG. ESG (Environmental, Social, and Governance) is a much broader framework encompassing all three pillars. CDP is considered the gold-standard platform for reporting the environmental component of ESG. Many companies use their CDP response to inform the environmental section of their broader ESG reports.
For most companies, CDP reporting is technically voluntary. However, due to immense pressure from investors, customers, and regulators, it has become de facto mandatory for large, publicly traded companies and those in high-impact sectors. Furthermore, an increasing number of governments are making TCFD-aligned reporting mandatory, and since CDP is aligned with TCFD, it effectively becomes the vehicle for compliance.
A CDP score of ‘B’ indicates a strong management level. It means the company has demonstrated a good understanding of its environmental impacts, has implemented robust and effective management strategies to address them, and provides comprehensive disclosure. While it may lack the pioneering, best-practice actions of an ‘A’ score, a ‘B’ is a respected score that signals to the market that the company is a responsible environmental steward.
There is no fee for a company to disclose directly to CDP. The primary cost is internal: the staff time, resources, and potential consulting services required to gather data, conduct analyses, and complete the comprehensive questionnaire. However, CDP does charge a fee for its scoring service, which is essential for receiving a public grade.
Yes, SMEs can and are encouraged to report to CDP. While the initial request-for-information is typically sent to large companies, any organization can disclose through CDP’s online response system. For SMEs, this is an excellent way to prepare for requests from larger corporate customers, attract investment, and build a reputation for transparency. Using tools like Climefy’s carbon calculator for small & medium companies can make the process much more accessible.
