Why Companies Need a Carbontology for Effective CO2 Management

Traditional ESG tools and estimation-based approaches fail to provide the accuracy, scalability, and automation needed for effective CO₂ management. 

Carbmee’s Carbontology uses a transactional data model. It combines real-time ERP and supply chain data. This helps track emissions accurately, meet regulations, and provide useful insights.

Unlike fragmented, survey-based methods, this approach creates a single source of truth. This approach enables companies to move from assumptions to data-driven sustainability strategies.

Ontology-based data models are transforming enterprise software by providing a structured, semantic framework for managing complex information. An ontology defines the relationships between different data entities, ensuring seamless integration, interoperability, and contextual understanding across systems.

Unlike traditional databases, which store data in isolated tables, an ontology maps how entities interact in a real-world environment. This allows for more accurate, scalable, and automated decision-making.

When applied to CO2 management, an ontology creates a unified model of an organization’s emissions landscape.

This is essential in an era where supply chains are becoming more complex, regulatory requirements are tightening, and businesses need precise carbon tracking to meet sustainability goals.

A strong ontology isn't just about structuring emissions data. It’s about ensuring that emissions models accurately reflect real-world complexity and drive decision-making. The biggest challenge in carbon management today is that most solutions rely on overly simplified models. These fail to capture how emissions truly behave across supply chains.

Traditional carbon tracking methods, like spend-based models, static LCAs, and supplier surveys, have common issues. They often lack the accuracy, automation, and scalability needed for effective CO₂ management.

These are some of the reasons:

• Spend-based models assume that cost equal emissions. They ignore how materials are sourced, how energy-intensive the production process is, or whether suppliers use renewable energy.
• Static LCAs only provide a one-time snapshot. They cannot be used to provide a live, continuously improving model that adapts as suppliers, materials, and regulations change.
• Survey-based methods depend on supplier-reported data. This is often inconsistent, non-standardized, and prone to missing key emissions sources.

As a result, companies using these methods end up with fragmented, unreliable emissions data. This leads to poor decision-making, compliance risks, and higher costs from default values, such as CBAM penalties.

A well-designed ontology isn’t just a data model. It is a framework that makes emissions tracking accurate, automated, and actionable.

To achieve this, an effective ontology must:

1. Accurately Represent Real-World Business Entities

A supplier is more than just a name in a database. It connects to materials, production sites, transportation routes, and real-time emissions data.

A product is more than just an emissions factor. It changes as suppliers evolve, new materials come in, and regulations change.

1. Mirror Real-World Business Processes

A strong ontology must adapt dynamically as supply chain conditions evolve—not force companies into static reporting structures.

Example: When a supplier switches to low-carbon steel, the system automatically updates emissions calculations across affected products without manual intervention.

1. Integrate with Enterprise Systems for Live, Trusted Data

If emissions tracking isn’t embedded into real business workflows, it’s just compliance reporting—not actionable intelligence.

The ontology must ingest procurement data, supplier updates, and operational changes in real time, ensuring carbon data is always current and decision-ready.

The Carbontology isn’t just an ontology—it’s a transactional, self-improving CO₂ management system.

• It structures emissions data relationally, ensuring that as suppliers, materials, and energy sources change, emissions calculations automatically adjust.
• It eliminates manual data collection bottlenecks by connecting directly with ERP, procurement, and logistics systems.
• It turns emissions data into a real-time tool for decision-making. This helps companies choose better suppliers, improve product design, and lower regulatory costs.

Most carbon tracking tools treat emissions as an afterthought. They are separate systems that need manual updates. These systems often fall behind real changes in the supply chain.

The Carbontology ensures emissions tracking moves at the speed of business.

Managing CO2 emissions in enterprises is highly complex.

Data comes from various sources: ERP, SRM, PLM, MES, or modern data platforms.

These data sets are often structurally inconsistent, fragmented, and lack semantic interconnection. The Carbontology addresses these challenges by creating a transactional data foundation that standardizes data from different systems and maps it relationally.

Carbmee’s data model is based on core objects that represent the entire value chain of a company:

Structured or unstructured data like BOM (Bill of Materials), Material Descriptions or Energy Bills are not standalone objects but provide contextual input into the ontology. This enhances its semantic structure for better data organization and analysis.

Beyond the data model, the Carbontology provides a structured execution workflow for carbon management. This means that:

• Business logic is embedded within the ontology, ensuring that emissions data flows correctly across systems and departments
• Automated workflows enable seamless data validation, enrichment, and transformation.
• Regulatory compliance mechanisms ensure that reporting aligns with frameworks like CSRD, EUDR, and CBAM.

The Carbontology is more than a static data structure: it allows dynamic customization through Custom Fields, which can capture specific regulatory requirements or company-specific metrics. Integration with external emission reference databases such as Ecoinvent, Exiobase, and CBAM ensures scientifically validated emissions calculations. Continuous enrichment with carbmee’s proprietary database and real supply chain data provides an increasingly accurate representation of real-world emissions data.

To further enhance automation and scalability, the Carbontology supports data orchestration across multiple sources. This ensures that:

• Data ingestion, transformation, and reporting are automated and consistent.
• Workflows dynamically adjust to regulatory updates and operational changes.
• Stakeholders receive real-time insights into emissions reduction opportunities.

The next evolution of CO2 management is leveraging Large Language Models (LLMs) for enhanced analytics and decision-making. A dedicated LLM Layer can be integrated with the Carbontology, enabling:

• Automated insights and anomaly detection across emissions data.
• Intelligent recommendations for reduction strategies based on historical trends.
• Natural language queries, allowing non-technical users to interact with the emissions data in real time.

Carbmee’s Studio Layer ensures that the data modeled through the Carbontology is not just collected, but transformed into actionable insights.

Reporting and analytics tools enable companies to generate regulatory reports and develop targeted emissions reduction strategies.

Unlike traditional methods such as supplier questionnaires or high-level estimations, the transactional approach of the Carbontology offers significant advantages:

• Higher data quality: Real-time integration with ERP and production systems eliminates errors caused by subjective assessments.
• Scalability: Companies with complex supply chains can collect granular and automated data.
• Better decision-making: Instead of relying on rough averages, the Carbontology provides precise modeling based on real transactional data.

Many companies attempt to manage CO2 emissions by using generic ESG tools that lack a transactional data foundation. Without an ontology-based model:

• Data remains fragmented, leading to inaccurate or incomplete emissions reporting.
• Manual data collection (e.g., surveys) increases administrative burden and the risk of human error.
• Decision-makers base their decisions on assumptions rather than real transactional data, which reduces the effectiveness of carbon reduction strategies.
• Compliance with evolving regulations (e.g., CSRD, EUDR) becomes significantly more challenging.

A key advantage of the Carbontology is streamlined primary data collection across the supply chain. Instead of manually sending surveys to suppliers and aggregating their data, companies can:

• Extract supplier data directly from ERP and procurement systems,
• Enrich it with existing LCA models and historical values,
• Determine where to start your decarbonization journey to maximise impact by establishing a consistent, scientifically validated data foundation in orchestration with your supply chain

Just as ontologies have revolutionized data-driven decision-making in enterprise software, the Carbontology introduces a new paradigm for CO2 management. Companies seeking to deeply understand and optimize their emissions sources cannot bypass a semantic abstraction of their supply chain.

With the Carbontology, Carbmee provides the essential framework to move sustainability strategies from theoretical discussions to real-world implementation based on precise and reliable data.

Carbontology is a continuously self-improving carbon management model that evolves over time, providing higher accuracy than financial accounting. It enables companies to solve data challenges without use-case limitations, offering infinite possibilities for carbon management.

The model is built on three core layers: the Master Data Layer, ensuring data consistency; the Transactional Data Layer, capturing real-time business operations; and the Kinetic-Semantic Data Layer, which allows companies to dynamically adjust and enhance their emission models over time based on new data and insights.

It integrates with ERP and SRM systems, supports LCA modeling and primary data workflows, and intelligent layer Studio for reporting, analytics, and decision-making.

Through structured and unstructured data ingestion, along with LLM-powered enhancements, Carbontology transforms carbon management into a dynamic, enterprise-wide capability that is significantly superior to other approaches, such as questionnaire-based vendors, generic ESG reporting tools, CSRD-focused carbon management providers, or LCA providers. 

Unlike these methods, which often lack data integration, automation, and real-time insights, the Carbontology establishes a single source of truth that improves over time, ensuring scalability, precision, and compliance for modern enterprises.
