PCF Database & CO₂e Database: What It Is, Why It Matters and What to Look For

‍

A PCF database — also referred to as a CO₂e database, carbon database, or emission factor database — is a structured, referenced collection of emission factors that quantify the greenhouse gas (GHG) emissions associated with specific materials, production processes, energy sources, and logistics activities. It is the quantitative backbone of every Product Carbon Footprint (PCF) and Scope 3 emissions calculation: without a reliable database of emission factors, activity data — material quantities, energy consumption, transport distances — cannot be translated into CO₂e values.

‍

The quality, coverage, and update frequency of the emission factor database used in a PCF calculation directly determines how accurate, comparable, and audit-ready the resulting carbon figure is.

‍

What a PCF database contains

‍

A comprehensive PCF or CO₂e database provides emission factors across the key inputs needed for lifecycle-based carbon calculations:

‍

• Materials: CO₂e per kg for metals (steel, aluminium, copper, titanium), polymers (PP, PE, PA, PEEK), composites, glass, ceramics, and other industrial inputs — often differentiated by production route (primary vs. secondary, energy source, country of production)
• Electronics and electrical components: CO₂e for semiconductors, PCBs, capacitors, connectors, displays, and other electronic components
• Manufacturing processes: CO₂e per unit of energy or per process step for operations such as casting, forging, injection moulding, machining, welding, coating, and assembly
• Energy: CO₂e per kWh for electricity grids by country and year — a factor that varies significantly between markets (e.g. Norway's hydro-dominated grid vs. coal-intensive grids in Asia)
• Logistics and transport: CO₂e per tonne-kilometre by transport mode (road, rail, sea freight, air freight)
• Packaging materials: CO₂e for cardboard, plastics, foam, wood, and other packaging inputs
• End-of-life scenarios: CO₂e for recycling, incineration, and landfill, including recycling credits

‍

Why database quality is a compliance issue

‍

Both ISO 14067 and the GHG Protocol specify data quality criteria that emission factors must meet for a PCF to be considered robust and audit-ready:

‍

• Accuracy: emission factors should reflect actual production conditions, not theoretical or outdated averages
• Representativeness: factors should be geographically and technologically representative of the actual supply chain being assessed
• Completeness: all relevant lifecycle stages and material inputs should be covered
• Timeliness: emission factors should be regularly updated to reflect changes in energy mixes, production technology, and supply chain geography
• Transparency: the source, methodology, and assumptions behind each factor should be documented and verifiable

For CSRD reporting — where all disclosures are subject to external assurance — and for regulatory submissions under the EU Battery Regulation or CBAM, these quality criteria are not optional. Auditors will question the provenance of emission factors, and generic or undocumented data will not hold up to scrutiny.

‍

Primary vs. secondary data in a CO₂e database

‍

PCF and LCA databases contain two types of emission factors, which correspond to the primary and secondary data distinction in the GHG Protocol:

‍

Secondary emission factors (also called background data) are derived from representative industry datasets, life cycle databases (such as ecoinvent or ELCD), or scientific literature. They represent industry averages or typical production conditions and are used when supplier-specific data is unavailable.

‍

Primary emission factors are derived from actual production data at a specific facility, from a specific supplier, or for a specific material lot. They represent the highest level of accuracy and are increasingly required in regulatory contexts — particularly for CBAM (where default values carry significant cost penalties) and the EU Battery Regulation.

A high-quality PCF database provides well-documented secondary emission factors as the baseline — while enabling integration of primary supplier data where available, producing the most accurate possible carbon calculation.

‍

What distinguishes a professional CO₂e database

‍

Not all carbon databases are equal. Key differentiators for professional, regulatory-grade CO₂e databases include:

‍

• Regular update cycles: emission factors change as energy mixes shift, production technology improves, and supply chain geographies change. An outdated database systematically produces incorrect results.
• Geographic differentiation: a single global average for aluminium production, for example, is far less accurate than country- or region-specific factors that reflect the actual energy mix of the production location.
• Production-route differentiation: primary vs. recycled material, different smelting routes, different energy inputs — each produces meaningfully different emission factors.
• Independent validation: factors should be verified against published literature, LCA databases, or industry data, not self-reported without external review.
• Coverage depth and breadth: a database that covers only basic materials leaves significant gaps for complex manufactured products with electronics, coatings, or specialty components.
• Integration with calculation tools: a database that connects directly to PCF calculation workflows and BoM mapping reduces manual effort and error.

The sustamize CO₂e database

‍

The sustamize CO₂e database is designed for industrial PCF calculations at scale, providing verified emission factors across materials, electronics, manufacturing processes, logistics, and energy — differentiated by country and production route where relevant, and regularly updated to reflect current supply chain conditions. It is the data foundation underlying the sustamizer® PCF calculation platform, enabling companies to calculate ISO 14067 and GHG Protocol-aligned product carbon footprints across complex bills of materials.

‍

For procurement teams evaluating material choices and suppliers, and for sustainability teams building Scope 3 inventories and CSRD-compliant reports, the database provides the emission factor foundation needed to move from approximate estimates to verifiable carbon data.
