Match Every Chemical to the Right Emission Factor — In Days, Not Months
Free, expert-guided CAS Mapping that boosts Scope 3.1 coverage — so you can publish auditable numbers fast.
Why most mapping attempts still fail
Spreadsheet
chaos
Hours lost hunting CAS numbers across disconnected sources—one typo can derail an audit.
Name-only matchers guess, they don’t know
Generic tools ignore molecular structure, so “propylene glycol” might inherit the footprint of “propylene oxide.”
Endless consultancy loops
External experts fix today’s gaps, but the meter starts ticking again every time your portfolio changes.
Patchy public
factors
Even the best free datasets cover <50 % of a typical chemical portfolio, leaving you to defend assumptions.
The Carbon Minds solution
A mapping service based on our TÜV-certified methodology and a database of 1,500 + chemicals.
We lift coverage to >90 % in about a week—free of charge.
What Sets Carbon Minds apart?
Four reasons our Emission Factor Mapping Service delivers faster, fuller and audit-ready data:
Access high-quality factors for more than 1 500 chemicals and plastics, giving most portfolios direct matches from day one.
First we map exactly on CAS number; when a factor is missing, our engine proposes a chemically similar proxy reviewed by expert chemists.
Every dataset is built with a TÜV-verified methodology that meets ISO 14040/44/67 and TfS requirements, so auditors sign off with confidence.
High-impact gaps can be closed by custom datasets
How it works
Our Emission Factor Mapping Service helps you close data gaps and address inconsistencies in Scope 3.1 emissions reporting by automatically mapping chemical substances using CAS IDs. This eliminates the need for time-consuming manual matching, providing you with consistent and accurate emissions data. If certain chemicals are missing from the database, we focus on closing those data gaps: we offer our modeling on demand services or, alternatively, provide similar chemical substances (proxys) with the support of our automated proxy suggestion tool.
Emission Factor Mapping
Automated Mapping Based on CAS-IDs
First, we identify all products in your Scope 3.1 inventory that have emission factors available in the Carbon Minds database. This mapping is based on CAS IDs, numerical identifiers for chemical substances. Remaining data gaps are addressed in the next steps.
Prioritization of data gaps
Invest in data quality where it matters most
Prioritize data gaps based on their expected impact on your Scope 3.1 results. High-priority data gaps are filled using our on-demand modeling service leading to higher data quality, while low-priority gaps will be filled with proxies
Modeling On Demand
Higher quality
With our Modeling on Demand service, we model the missing emission factors for you using our third-party certified methodology, allowing you to fill data gaps with representative data.
Proxy Mapping
Lower quality
For less critical data gaps, our proxy suggestion engine identifies the substances in our database most similar to your target based on molecular structure, quantifying the similarity. You can use these suggestions to select suitable proxies.
Is this service for me?
If you recognise even one of the situations, you’ll benefit from automated Emission-Factor Mapping.
- My portfolio contains dozens or hundreds of CAS numbers and I’d rather pull factors from a database that already covers “1,500 + chemicals and plastics” than juggle spreadsheets.
- Customers keep asking for credible PCFs. Like Brenntag, I need to deliver “transparent, credible and comparable” figures—fast.
- Scope 3.1 deadlines are looming. Manual name-matching tools can’t keep pace, and errors risk my compliance effort.
- Chemicals drive most of my footprint. I produce or use chemicals in plastics, pharma, rubber, petroleum, FMCG or distribute them—and need scalable factors.
- Auditors ask for third-party assurance. Data that is ISO/TfS compliant and TÜV-reviewed lets me answer with confidence.
FAQs
How broad is your data coverage?
The cm.chemicals database contains data on more than 1,500 chemicals and plastics, making it the industry's largest ISO- and TfS-compliant source.
How fast can we expect results?
Our advanced modelling approach enables a quick turnaround, so custom data or proxy suggestions arrive "swiftly" to meet tight project timelines.
What happens if my substance has no published emission factor?
The service identifies chemicals with similar impacts and delivers proxy factors, or offers on-demand modelling to fill the gap - all documented for transparency.
How do I know the factors are credible?
All datasets come from a third-party-certified methodology (ISO 14040/44/67, TfS, UEIL & ATIEL) reviewed by TUV Rheinland, ensuring trust and audit readiness.
Which teams typically use the results?
Sustainability managers, environmental data analysts, compliance officers - essentially anyone tasked with Scope 3.1 reporting or LCA/PCF delivery. Training materials note uptake across "IT, Marketing, Sales, Production, Sustainability Management".
