Complete the CDP questionnaire with real decarbonization data — not estimates.
Ecomiles provides the data CDP requests in sections C4, C6, and C7, ready to copy and paste into the disclosure system.
CDP (Carbon Disclosure Project) is the world’s leading environmental disclosure system. More than 24,000 companies respond annually — and investors representing over US$136T in assets use this data to inform decisions. Your CDP score directly impacts access to capital, ESG reputation, and competitiveness in procurement.
The question is: how do you report real Scope 3 decarbonization progress?
How the CDP questionnaire is structured
In 2025, CDP unified the climate, forests, and water questionnaires into a single corporate questionnaire with 13 modules. Modules 1–6 are integrated; Module 7 is dedicated to climate change. The most relevant parts for reporting Scope 3 decarbonization are:
Module 4 — Targets & Performance
Where you disclose reduction targets (absolute or intensity) and progress against them. Includes questions like C4.1a (absolute targets), C4.2 (percent progress), and C4.3b (emissions reduction initiatives).
Module 6 — Emissions Data
Where you report quantitative emissions data by scope. Question C6.5 requests a Scope 3 breakdown by category — including Category 7 (employee commuting).
Module 7 — Climate Change
A climate performance module with guidance on verification and supporting documentation for reported emissions.
The challenge: question C4.3b
Question C4.3b is where CDP asks you to describe your concrete emissions reduction initiatives. It’s not enough to state a target — you must fill out a table with specific data for each implemented initiative.
What CDP requires in the C4.3b table
Initiative category & Activity type
The initiative type (e.g., Transportation — Employee commuting) and activity subtype. Both columns are mandatory — partial data does not score.
Estimated annual CO₂e savings
Annualized CO₂e savings in metric tons. If the initiative did not cover 12 months, CDP asks for an annualized projection.
Scope(s) or Scope 3 category
Select where the reduction occurs. For employee commuting: Scope 3 — Category 7: Employee commuting.
Investment required & Payback period
Required investment (in local currency) and payback period. Rows with “0” investment may also be accepted.
Important tip: CDP scores based on the sum of CO₂e savings reported in the “Estimated annual CO₂e savings” column. The more initiatives documented with real data, the higher the score in the Management category.
How Ecomiles populates each CDP field automatically
The business.ecomiles.app dashboard generates exactly the data each C4.3b column requires. Here’s the direct mapping:
Initiative category
→ Transportation: Employee commuting
The Ecomiles program fits squarely as a transportation initiative focused on commuting, with a Company policy or behavioral change component.
Annual CO₂e savings
→ Available in the dashboard as tCO₂e by period
The platform automatically calculates the difference between the chosen commuting mode and the baseline emissions scenario. The output is in metric tons — exactly as CDP requires.
Scope 3 — Category 7
→ Already categorized in the dashboard
All reduction data is automatically assigned to Scope 3, Category 7 (Employee commuting) — no manual reclassification.
Investment & Payback
→ Program cost and ROI
The dashboard includes financial metrics that map directly to the investment and payback fields required by C4.3b.
Beyond C4.3b: data for the other relevant sections
Ecomiles doesn’t just support one question — it provides data for multiple sections in the CDP questionnaire:
C4.1a — Absolute targets
Use the dashboard’s cumulative reduction data to demonstrate progress against Scope 3 targets that are SBTi-approved or in validation.
C4.2 — Progress against targets
The dashboard’s time series shows the month-by-month reduction curve, making it easy to calculate % progress versus a base year.
C6.5 — Scope 3 breakdown
Mode-level breakdown supports the quantitative detail for Category 7 required in C6.5.
Impact on your CDP score
Scoring: Management level
The Targets category can represent up to 25% of the score, and Emissions Reduction Initiatives is a key Management criterion. Reporting initiatives with real data — not just stated targets — is what separates a B from an A.
Third-party assurance
To reach A/A- scores, CDP expects third-party verification for disclosed emissions, including Scope 3. Ecomiles’ methodology is audited by KPMG, which directly supports this requirement.
In short: companies using Ecomiles can report to CDP with granular, audited, and correctly categorized data — moving from intent statements to proven results. That’s the path from Disclosure to Management and Leadership.
Companies already use Ecomiles data to fill out their CDP questionnaires with real evidence of Scope 3 reductions.
🚀 Next step
1️⃣ Activate the program
We define ESG engagement targets and activate variable compensation via a prepaid Mastercard card for your employees.
2️⃣ Collect real data
In weeks, the dashboard shows CO₂e reduction data categorized by mode and period.
3️⃣ Export to CDP
Data comes out in the exact format to populate C4.3b, C4.1a, C4.2, and C6.5 — without rework.
The CDP 2026 deadline is approaching.
Companies that already have data in place will have a significant competitive advantage.
Don’t wait until the last month to build the questionnaire.
