Preparing for CDP

CDP Consultant: When and Why to Work with a CDP Expert

A CDP consultant (or CDP expert) supports companies in preparing, structuring, and optimising their response to the Carbon Disclosure Project (CDP) questionnaire. Their role is twofold: ensuring compliance with CDP’s expected level of formalisation while maximising the score, all while significantly reducing the time required from internal teams.

For SMEs, mid-sized companies, and large organisations facing customer or investor requests, working with a CDP expert often becomes a strategic lever, rather than a simple operational support.

What Is a CDP Consultant?

A CDP consultant is a specialist in the CDP questionnaire and its scoring methodology.

They have in-depth expertise in:

  • the structure of the questionnaire: the different environmental themes (climate, water, forests, biodiversity, plastics) and modules (IRO identification, governance, environmental performance, business strategy, etc.),
  • the criteria that have a direct impact on the score,
  • the level of formalisation expected in responses,
  • and the links between CDP, CSRD, ISO 14001, and EcoVadis.

Unlike many other frameworks, CDP is entirely declarative: it is not the uploaded documents that are assessed, but the quality, consistency, and precision of the answers themselves.

This is precisely where a consultant’s expertise makes a decisive difference.

Good to know: a partially completed answer can result in a total loss of points for a question, even if most of the expected elements are present.

Why Work with a CDP Consultant?

1. Understanding What Actually Drives the Score

CDP relies on a complex scoring logic that is often misunderstood, even by experienced ESG teams.

A CDP consultant helps to:

  • identify the questions that carry the most weight in the final score,
  • understand blocking or gating criteria,
  • avoid structural or scope-related mistakes.

As a result, efforts are focused on what truly allows a company to move from D to C, or from C to B.

2. Bringing the Right Level of Formalisation to Responses

CDP does not only assess the actions implemented, but how they are described:

quantified targets, clearly defined scopes, explicit methodologies, documented governance.

A CDP consultant turns information that is often fragmented—but already available—into clear, structured responses aligned with the questionnaire’s exact expectations.

3. Saving Valuable Time on a Time-Consuming Exercise

Answering CDP typically requires dozens, sometimes hundreds, of hours:

  • understanding the questionnaire,
  • collecting data,
  • rewriting and structuring answers,
  • internal validation,
  • final reviews before submission.

CDP support enables companies to significantly reduce this workload, while securing the quality of the final submission.

4. Securing Credibility with Clients and Investors

In most cases, companies respond to CDP following a request from a key customer or financial partner.

A CDP consultant helps achieve a score that is:

  • easy to understand,
  • defensible in tenders and procurement processes,
  • and commercially valuable.
Good to know: more than 24,000 companies now disclose through CDP, making it a reference standard for international buyers and investors.

When Should You Engage a CDP Consultant?

For a First-Time CDP Disclosure

For a first participation—especially for SMEs and mid-sized companies—the main challenges are to:

  • understand the methodology,
  • avoid penalising mistakes,
  • survive the questionnaire… while still achieving a credible score.

A “first steps” support approach helps build solid foundations without unnecessary overinvestment.

When a Minimum Score Is Required

Some companies face direct score pressure (customer requirement of a minimum B score, supplier benchmarking, tenders).

In this case, the objective is clear: achieve the best possible score with existing data, then identify improvement areas.

When Time Is Limited or an Existing Score Needs Improvement

For companies already rated, a CDP consultant can help to:

  • accelerate completion,
  • improve response formalisation,
  • maintain or increase the score,
  • integrate CDP into a broader ESG roadmap.

What Tasks Can Be Entrusted to a CDP Consultant?

Area CDP Consultant’s Role Concrete Benefit
Scoring analysis Identify key questions and blocking criteria Targeted score improvement
Response structuring Rewrite answers according to CDP formalism Clearer, higher-impact responses
Prioritisation Focus efforts on what truly matters Time savings
Critical review Detect inconsistencies and gaps Reduced risk of underscoring
Forward planning Prepare future disclosure cycles Continuous improvement

A CDP Consultant Approach Tailored to Your Situation

Not all companies face CDP in the same way.

Effective CDP support adapts to:

  • company size (SME, mid-sized, large corporate),
  • number of previous disclosures,
  • level of pressure on the score.

Some organisations need methodological framing, others require strong operational support—or even full ownership of the disclosure process.

CDP Consultant: What Are the Concrete Benefits?

Working with a CDP consultant typically allows companies to:

  • achieve a higher score with the same perimeter,
  • significantly reduce internal workload,
  • secure the credibility of the disclosure,
  • better leverage results with clients and investors,
  • prepare more calmly for upcoming requirements (CSRD, IFRS S2).

It is less a cost than a strategic investment in an exercise that has become central to commercial and financial relationships.
