Use this page when you are unsure how to answer a specific reduction measure question in the Carbon Reduction Efforts section. For general guidance, refer to the Self-Assessment Overview.
Does nuclear energy count as a “renewable source”?
Under EU regulation 2022/1214, nuclear energy is not classified as renewable. However, the EU acknowledges that nuclear energy is a "transitional low-carbon" alternative.
Since supplier+s focuses on carbon reduction, electricity purchased from a verified nuclear source can be included in your implementation degree for the question on renewable electricity.
Examples of sources to include (where verified):
wind
solar
hydro
nuclear (verified supply)
other low-carbon sources
How do I choose the right implementation degree?
Select the range that best represents the overall level of implementation across the Business Segment.
Example:
If the measure is fully implemented at 1 of 2 locations, 41–60% (medium share) is typically the best fit.
If the measure is partly implemented across multiple locations and adds up to roughly half coverage overall, 41–60% (medium share) can also be appropriate.
If the measure is only being piloted in 1 of 3 locations, select 1–20% (pilot share).
The goal is to reflect segment-wide coverage, rather than the situation at a single site.
If you are uncertain:
Consult colleagues with expertise in carbon reduction, facility management, ESG, or procurement. You can also invite them to your account.
Answer to the best of your knowledge.

When can a compressed air system be considered “optimized”?
A compressed air system is considered optimized when the following four activities are implemented regularly and anchored in operational practices:
Leakage control
Regularly checking for leaks and fixing them promptly.Demand management
Avoiding pressure peaks, ensuring consistent utilization, and switching off systems during inactive periods.Pressure level minimization
Operating at the lowest possible system pressure and using decentralized boosting only where required.Regular maintenance
Maintaining compressors, air intake filters, and replacing outdated systems.
How should I select the implementation degree for compressed air optimization?
Choose the level that reflects how many activities are performed and how broadly they are applied.
Example:
If 1 of 3 locations performs all 4 activities → select 21–40% (minor share)
If all locations perform only 2 of the 4 activities → also 41–60% (medium share)
The goal is to represent the overall share of optimized systems across the business segment.
Do supplier+s responses count as primary data under CSRD / ESRS E1?
Yes, supplier+s responses qualify as primary data when they are based on:
supplier-specific quantities
metered energy consumption
directly reported emissions
documented methods, periods, and units
The GHG Protocol defines primary data as “data from specific activities within a company’s value chain” (Corporate Value Chain (Scope 3) Accounting and Reporting Standard, page 140) and lists, among others:
meter readings
purchase records
supplier-provided measurements
engineering models with supplier inputs
as acceptable methods (Scope 3 Frequently Asked Questions, Question 16).
This means supplier+s data can be used directly in CSRD/ESRS E1-compliant Scope 3 reporting.
How can I provide additional information to my customer?
We appreciate your commitment to reducing your carbon footprint. It is great to hear that you may have initiatives that go beyond the scope of the questionnaire.
The questionnaire focuses on the most material carbon hotspots by industry and country. To keep results comparable, some specialized measures are not included.
What you can do:
Use the Carbon Accounting Module to demonstrate reductions achieved through your own measures.
Share additional initiatives directly with your customer.
