Fixed-price deliverable

Your CDP questionnaire, answered and evidenced

A large customer has asked you to disclose through CDP, the request sits in your procurement contact's follow-up list, and the cycle runs on fixed dates: in 2026 the portal opens on 17 June and responses close in late October. Not responding is visible too, as a failure-to-respond status shown to the customer who asked. We take your invoices, meter readings and existing documents, build the emissions numbers and answer the questionnaire for your scope, with every value traced to a source or clearly labelled as an estimate. What we cannot evidence goes on a gap list that tells you exactly what to fix before next year's cycle.

The scheme
CDP environmental disclosure: since 2024 one integrated corporate questionnaire, scored per issue from A to D- on climate change and, where requested, forests and water security
Who asks
Your customers, through CDP's supply chain programme, and banks and investors. In 2025, over 270 major buyers requested data from around 45,000 suppliers
The deadline
One cycle per year. In 2026 the portal opens 17 June, the scoring deadline is 16 September, and the questionnaire closes for good in the week of 26 October
The fee catch
Responding only to a customer request carries no CDP admin fee. The fee applies when investors also request your disclosure or you volunteer without a request
What you buy
The questionnaire answered for your scope, SME or full version, with per-value provenance, plus a gap list of what to fix before the next cycle

The ask

CDP is the disclosure system large companies use to collect environmental data from their suppliers. A customer adds you to their CDP supply chain request, you receive an invitation to disclose, and the annual cycle takes over: in 2026 the response portal opens on 17 June, responses submitted by 16 September are scored, and in the week of 26 October the questionnaire closes and nothing can be changed. Your customer sees your response and your score. If you do not respond, they see that too: CDP assigns a failure-to-respond status to companies that were asked and stayed silent.

Since 2024 CDP runs one integrated corporate questionnaire instead of separate climate, forests and water questionnaires. Every discloser answers climate change datapoints; forests and water security appear when a requester asks for them; plastics and biodiversity datapoints are collected but not scored. Scores run from A to D- per issue, and the request is rarely a one-off: over 270 major buyers requested data from around 45,000 suppliers in the 2025 cycle, and the same request returns every year.

Who this applies to

Suppliers of large companies that run CDP supply chain programmes, which in Europe reaches deep into the mid-market: if one big customer uses CDP, their request lands on you regardless of your own size. Banks and investors drive the same request through their own CDP programmes.

Size decides which questionnaire you face. Companies under 500 employees and under US$50 million revenue qualify for the shorter SME version, which nearly 11,000 companies used in 2025; above those thresholds the full corporate questionnaire applies. We deliver both. The work behind either is the same: real emissions numbers built from real data, because the questionnaire asks for figures, methods and evidence, not intentions.

What you need to have ready

This list doubles as our intake. You will not have everything, and that is fine: what is missing becomes either a labelled estimate or a line on the gap list.

  • The CDP request or invitation email, so we work on your actual scope and the issues your customer activated
  • Electricity and gas invoices or meter readings for the reporting year
  • Fuel and fleet data: fuel cards, lease overviews, mileage records
  • Refrigerant top-ups from maintenance invoices, if you have cooling installations
  • An organisational overview: entities, sites, and who controls what
  • Prior footprints, energy audits or sustainability reports, if any
  • Environmental or energy policies and any reduction targets you have set
  • Certificates you hold, such as ISO 14001 or ISO 50001

What Humboldt delivers

The answered CDP questionnaire for your scope: every datapoint filled from your own records, your scope 1 and 2 emissions calculated from invoices and meter data, and every value carrying its provenance, the source document behind it or the estimation method used where primary data is missing. Estimates are labelled as estimates; nothing is dressed up as measured when it is not. If the same footprint work already exists in your evidence ledger, for instance from a CO2-Prestatieladder entry pack, we reuse it instead of rebuilding it.

Alongside the answered questionnaire you get the gap list: the datapoints where your data is thin, ranked by likely score impact and phrased so you can act on it before the next cycle, because CDP comes back every year and the second response should be better and cheaper than the first.

A senior specialist reviews the whole response before it reaches you. Then you, as the account owner, review, approve and submit in the CDP portal.

The price

Fixed scope, fixed price

Answered CDP questionnaire

from EUR 1,950 per questionnaire

You buy the finished deliverable, not hours and not software. We confirm the exact scope and price on a 20-minute call before any work starts, and the price we quote is the price you pay.

What the price includes

  • The CDP questionnaire for your scope answered end to end: the SME version if you qualify, the full corporate version if your size requires it
  • Your scope 1 and 2 emissions calculated from your own invoices, meter readings and fleet data, with spend-based estimates clearly labelled where primary data is missing
  • Every answer traced to a source document or a stated estimation method, so you can defend the response to the customer who asked for it
  • A gap list of missing data and weak spots, ranked by score impact, so you know what to improve before the next annual cycle
  • Review and sign-off by a senior specialist before anything is handed to you

Turnaround: 15 working days from receiving your documents. The CDP cycle has hard dates, so if you are close to the September scoring deadline, say so on the call and we will tell you honestly whether we can make it.

So we are clear about the boundaries

  • We do not promise a score. CDP scores each issue from A to D-, from Disclosure through Awareness and Management to Leadership, and the score depends on what your company actually does, not on how the form is filled.
  • You stay the account owner. You review the response, approve it and submit it in the CDP portal; we prepare, you sign.
  • CDP's own fees, where they apply, are separate and paid to CDP. If your disclosure is requested only by customers there is no CDP admin fee; if capital-markets signatories request it or you disclose voluntarily, CDP charges an admin fee (in Europe from EUR 2,975 in 2026).
  • We do not invent numbers. Where your data supports a value, we calculate it; where it only supports an estimate, we label the estimate and its method; where neither is possible, the gap list says so.
