Established in 2000, CDP operates the world's largest environmental disclosure system, providing a comprehensive platform for companies, cities, states, and regions to measure, manage, and ultimately mitigate their environmental impact.

At NetNada, we encourage any organisations to consider CDP as part of their disclosure roadmap mainly because the processes and learnings along the way are an invaluable experience for boards, executives and sustainability teams alike.

By encouraging voluntary disclosure, CDP empowers a wide array of stakeholders, including investors, policymakers, and the public, to make informed decisions that drive sustainable development and climate action. CDP holds the distinction of being the first organization to leverage the influence of investors to encourage corporate disclosure on environmental matters.

Understanding CDP's core goal

CDP, formerly known as the Carbon Disclosure Project, is a global non-profit organization that operates the world's only independent environmental disclosure system. Driven by a commitment to transparency, CDP maintains the richest and most comprehensive dataset on corporate and governmental environmental action. 

The organisation plays a crucial role in mobilising influencers across enterprise, capital markets, policy, and science, thereby enabling decisions that are most impactful for the planet. 

With the belief in the power of data CDP aims to drive meaningful change.

What can be disclosed through CDP?

A CDP disclosure encompasses key environmental areas reflecting a broad understanding environmental indicators including

  • climate change, 
  • water security, 
  • forests, 
  • and plastics. 

The expansion of CDP's focus beyond carbon emissions indicates an evolving understanding of environmental sustainability, acknowledging the critical roles of water resources, forests, and plastic pollution in the overall health of the planet.   

Disclosing environmental data through CDP offers a multitude of benefits for companies, investors, and customers alike, fostering a more sustainable and transparent global economy.

Who can disclose environmental data through CDP?

CDP provides a platform for a wide range of entities to disclose their environmental data. Recognising that environmental impact extends beyond the corporate sector, CDP also facilitates disclosure for cities, states, and regions. 

CDP also has disclosure models for other entities beyond corporates:

  • Cities, states, and regions, and public authorities can also submit disclosures. They disclose their environmental information through the CDP Portal as well. Their questionnaires request qualitative and quantitative environmental data on themes like governance, climate hazards, emissions, energy, urban planning, forests, food, waste, and water security. Cities can report simultaneously to multiple climate initiatives through CDP-ICLEI Track.
  • Self-Selected Companies (SSCs), cities, states, or regions: Any organization is welcome to submit information without a disclosure request by registering as a self-selected entity. Private companies can also report through CDP’s private markets disclosure platform. SSCs must pay the admin fee to disclose and receive a score if they submit by the deadline.

The global reach of CDP is extensive, with regional offices and local partners spanning over 50 locations and engaging disclosers from more than 90 countries. Any organization, even without a direct disclosure request, can voluntarily report as a self-selected company, city, state, or region.

How does the CDP reporting process work for organizations?

The CDP disclosure journey involves a structured, step-by-step process that enables companies to effectively communicate their environmental performance. This process generally encompasses registration with CDP, completing the disclosure questionnaire, undergoing verification if required, submitting the response, and ultimately receiving a performance grade.

Step 1: Registration on the CDP Portal

The initial step is registration on the CDP Portal, accessible through the CDP website. New users are required to complete a registration form to gain access to the platform. Existing users typically receive an email invitation from CDP with instructions on how to sign in. Importantly, companies can also choose to register as Self-Selected Companies (SSCs) even if they have not received a direct request to disclose from stakeholders.

Step 2: Completing the CDP Disclosure Questionnaire

Once registered, companies proceed to the reporting phase, which involves completing the comprehensive disclosure questionnaire within the CDP Portal. The CDP reporting cycle typically opens in April, with the deadline for scored submissions falling in early July.

In a significant development for the 2024 reporting year, CDP has integrated its previous three separate questionnaires on climate change, forests, and water security into a single, unified corporate questionnaire. Recognizing the diverse nature of businesses, CDP offers different versions of the questionnaire, including a full corporate questionnaire designed for larger organizations and a simplified SME questionnaire tailored to the needs and resources of small and medium-sized enterprises. To streamline the process and ensure relevance, companies are presented only with questions that pertain to the specific environmental issues they have been requested to disclose on.

Step 3: Verification of Environmental Data

In some instances, CDP may require companies to undergo verification of the environmental data they have disclosed. This external validation is typically conducted by accredited third-party verifiers or by CDP's own verification team. Reflecting a commitment to data accuracy and integrity, the verification requirements for Scope 1 and Scope 2 greenhouse gas emissions were increased to 100% in both 2023 and 2024.

Step 4: Submission of the CDP Response

After completing the questionnaire and undergoing verification if necessary, companies must submit their responses through the CDP Portal by the designated deadline. It is important to note that amendments to previously submitted questionnaires can often be made before the closure of the reporting cycle.

Step 5: CDP Scoring and Performance Evaluation

The final stage of the disclosure process is scoring, where CDP evaluates the submitted responses based on the quality and completeness of the disclosure, as well as the robustness of the company's environmental programs. Companies are assigned a score ranging from A (highest) to F (lowest), providing a clear indication of their environmental performance. Following the evaluation, companies receive a detailed scorecard that offers valuable feedback on their performance and identifies areas for potential improvement. CDP scores are typically released towards the end of the calendar year or in the early months of the following year.

What is CDP scoring and what do the different score levels signify?

CDP assigns scores to companies and cities based on their environmental disclosure and performance to illustrate their progress and motivate further action. Scores range from D- to A, with F being assigned to organizations that fail to provide sufficient information or do not respond at all.

 

  • A "D score" (Disclosure) indicates the initial step of reporting with significant room for improvement. 
  • A "C score" (Awareness) shows some steps taken to address environmental issues. 
  • A "B score" (Management) reflects good environmental management and disclosure. 
  • An "A score" (Leadership) is the highest rating, signifying strong environmental leadership and best practices. 

These scores help organizations benchmark themselves against peers and inform stakeholders about their environmental performance.

Scoring Level

Disclosure

D- to D

Focuses on the completeness and relevance of the environmental information provided. Indicates that a company has started its environmental journey by disclosing data.

Awareness

C- to C

Evaluates the company's understanding of the links between environmental issues and its business activities. Assesses the thoroughness of the company's self-evaluation regarding its impact on people and ecosystems.

Management

B- to B

Recognizes companies that are implementing policies and taking actions to address their environmental concerns and minimize their negative impacts. Shows evidence of good environmental management but may not yet demonstrate leadership.

Leadership

A- to A

Awarded to companies that demonstrate best practices, strategic actions (such as science-based targets), and overall environmental stewardship. These companies are recognized as pioneers in environmental responsibility and set benchmarks for others.

Is CDP disclosure mandatory, and what are the benefits of participating?

While CDP disclosure is not currently mandatory for most organizations, there is a global trend towards mandatory environmental reporting. Participating in CDP offers numerous benefits. It helps organizations identify and manage their environmental impacts, demonstrate their commitment to sustainability to stakeholders and investors, benchmark performance against peers, stay ahead of evolving environmental regulations, and potentially attract investors who consider environmental risks and opportunities. 

  • Managing Environmental Impact: CDP helps states and regions, cities, investors, and companies manage their effect on the environment . The disclosure mechanism creates urgency for organizations to take the first step in managing climate change.
  • Meeting Stakeholder Expectations and Requests: CDP gives customers, investors, and other stakeholders a path to request environmental information from organizations.. Hundreds of organizations request or engage their stakeholders to report key environmental data each year.  Responding to these requests demonstrates transparency.
  • Benchmarking and Performance Evaluation: CDP assigns scores to companies and cities to illustrate their progress and motivate them to take the lead in environmental action.. These scores provide a clear way for organizations to see how they stack up against peers. Organizations can also use scores from previous reports to inform future disclosures.
  • Access to Data, Research, and Insights: CDP uses self-reported data to provide comprehensive data for various uses, including trend mapping and highlighting environmental leaders. This data is also freely available to the public through CDP’s research hub, allowing reporting organizations to guide their own disclosures by seeing how others are making progress.
  • Recognition and Leadership: CDP creates "A Lists" to highlight entities that are leading the way with "A" scores in environmental action and transparency. Achieving "A List" status provides recognition for an organization's efforts.
  • Identifying Opportunities for Improvement: By reviewing their complete disclosure and CDP score, organizations can identify opportunities to improve their environmental impact.The scoring system highlights areas where more work is needed to reduce negative environmental impacts.
  • Enhancing Investor Relations: CDP scores and disclosure processes provide tangible resources that reporting organizations can provide for investors who include corporate social responsibility or climate risk in their investing decisions. Showcasing environmental impact and plans for improvement can lead to improved investor relations.. Investor signatories also gain access to disclosure data to inform their decision-making.
  • Alignment with Global Frameworks: CDP aligns with other initiatives like the Task Force on Climate-related Financial Disclosures (TCFD) and the GHG Protocol. This alignment helps streamline reporting for organizations and ensures they submit high-quality, comparable, and standardized information. CDP also collaborates with the Global Reporting Initiative (GRI) to standardize disclosures.
  • Supply Chain Engagement: CDP provides Supply Chain membership to support companies in disclosing emissions along their value chain and engaging with their suppliers. This helps in understanding and addressing scope 3 emissions, which are often the most significant.
  • Preparing for Mandatory Reporting: While CDP disclosure isn't currently mandatory, the world is quickly moving towards mandatory reporting. Engaging with CDP can help organizations prepare for potential future requirements.

What are the different types of memberships offered by CDP?

CDP offers several types of memberships to support different stakeholders in their environmental engagement:

  • Supply Chain Membership: For companies that want to engage their suppliers to disclose emissions along their value chain, providing tools and support for this process.
  • Reporter Services Membership: For organizations seeking tailored support, data, and insights on reporting and managing their environmental risks.
  • Investor Membership (Investor Signatories): Grants investors access to disclosed environmental data and scores from reporting companies to inform their investment decisions and engage with companies on environmental issues.

How does CDP ensure the quality and comparability of disclosed data?

CDP provides standardized questionnaires and detailed reporting guidance tailored to different sectors and entity types to ensure a degree of comparability in the disclosed data. The alignment of CDP's questionnaires with other frameworks like the TCFD and GRI also promotes consistency. Furthermore, CDP employs a scoring methodology that assesses the comprehensiveness and quality of the responses. While CDP does not directly verify all data, it does encourage and, for the highest "A" score, require companies and SMEs to verify their reported environmental data through accepted verification standards.

How is CDP evolving to address a wider range of environmental issues and drive greater impact?

CDP is continuously evolving to broaden its scope and deepen its impact. It has expanded beyond its initial focus on carbon emissions to include areas like water security, deforestation, and plastics. CDP's Five-Year Strategy aims to cover more environmental issues, increase the focus on targets aligned with climate science (like the 1.5-degree goal and net-zero), and accelerate change through enhanced disclosure, insightful data analysis, and targeted action. Collaborations with other organizations like the GRI to standardize disclosures further contribute to its growing influence and effectiveness in driving corporate and governmental environmental action.

What financial obligations exist for CDP disclosers?

Organizations that disclose to CDP may have financial obligations primarily in the form of administrative fees for submitting their disclosures. It's important to note that only companies and public authorities are required to pay this administrative fee, while cities, states, and regions do not.

Here’s a breakdown of the financial obligations:

  • Who pays the admin fee?
    • Companies requested to disclose by CDP’s Capital Market Signatories.
    • Self-Selected Companies (SSCs), which are companies that wish to disclose even if they have not been requested to do so by Capital Market Signatories or customers.
    • Public authorities.
    • Cities, states, and regions do not pay the admin fee.
  • Cost of Reporting: Reporting to CDP can cost between $1,055 and $6,500.

  • Types of Contributions (Fee Options) for Disclosers: CDP offers three fee options with varying benefits:

    • Enhanced fee: Offers the most benefits, including increased access to company responses, a comparative analysis report, tailored introduction to Accredited Solutions Providers, and supplier screening.
    • Foundation fee: Provides core benefits such as reporting through the CDP Portal, use of CDP's tools and guidance, and communication opportunities.
    • Essential fee: This is the most basic option with reporting and tool access, aimed at small to medium-sized enterprises (SMEs) and those with a limited budget, and is only available to disclosing organizations headquartered outside of specific regions (North America, UK, Europe, Japan, South Korea, Southeast Asia, Taiwan, Hong Kong, Australia, New Zealand, Bermuda, and Guernsey).
  • Fee Amounts by Region: The CDP admin fee varies by region and fee option. You can find a guide to the 2024 fees based on the organization's headquarters in the sources.

  • How CDP Uses Admin Fees: CDP uses these fees to maintain its online disclosure system, resources, support, and to increase traffic to their site and tools. Funding also supports annual updates to the questionnaire and improves compatibility with other reporting platforms.

  • Fee Exemptions: Companies are exempt from paying the admin fee if:


    • They have only been requested to disclose by a Supply Chain member, a Banks Program member, a Private Markets member, and/or the RE100 initiative. If they have been requested by one of these and a Capital Market Signatory, they will need to pay the fee.
    • They’ve received a request to respond from the RE100 initiative, Investor Signatories, and/or the Net Zero Asset Managers initiative and have not submitted a response to CDP in the last three years.
    • They have not been requested by any of the above organizations and have only received requests from Bank Program members and/or Supply Chain members.
    • Organizations based in Ukraine are currently exempt from paying the admin fee.
    • CDP is currently not accepting fees from companies based in Russia and Belarus, requesting that those fees be donated to a local environmental cause instead.
  • Membership Fees: Beyond the disclosure admin fee, CDP also offers memberships for supply chain, reporter services, and investors, which require their own fees and provide additional benefits and access to resources.

It's important to note that the fee structure and exemptions are subject to change.
