Product Carbon Footprint Services

Calculate, Verify, and Act with Confidence

A product carbon footprint measures the total greenhouse gas (GHG) emissions generated across a product lifecycle, from raw material extraction through manufacturing, distribution, use, and end-of-life. Clearyst provides the consulting expertise that makes PCF software produce credible, defensible results, then uses those results to drive decarbonization efforts. Arbor and Greenly are the platforms; Clearyst recommends the right fit and leads the work from calculation to action.
Talk to a PCF Consultant
Customers, regulators, and investors are now asking for product-level carbon data, not just corporate emissions totals. Many companies have started Scope 1, 2, and 3 reporting, but product carbon footprinting is often the next challenge.

The difficulty is not access to tools. It is applying the right methodology, aligning internal teams, and producing results that hold up under scrutiny.

Clearyst helps companies move from early-stage PCF efforts to structured, ISO 14067-aligned product carbon footprinting that supports compliance, customer requirements, and product-level decision-making.
The Definition

What Is a Product Carbon Footprint?

A product carbon footprint quantifies the total greenhouse gas emissions associated with a specific product across its lifecycle, expressed in CO2 equivalent. It is calculated using life cycle assessment methodology and standardized under ISO 14067, the global reference standard for product carbon footprints.

Corporate Carbon Footprint vs. Product Carbon Footprint

A corporate carbon footprint measures emissions across an entire organization, including Scope 1, 2, and 3. A product carbon footprint measures emissions tied to a single product across its lifecycle.
Corporate Carbon Footprint
Measures emissions across an entire organization, including Scope 1, 2, and 3. Supports regulatory disclosure and investor communication.
Product Carbon Footprint
Measures emissions tied to a single product across its lifecycle. Supports customer requirements, procurement decisions, and regulatory programs such as CBAM and Digital Product Passports.
Companies typically need both. A strong corporate Scope 3 foundation often accelerates product carbon footprinting, since supplier and materials data can be reused.

Cradle-to-Gate vs. Cradle-to-Grave

Product carbon footprints are defined by system boundaries:
Cradle-to-Gate
Covers raw materials through manufacturing. Commonly used for B2B products and CBAM reporting.
Cradle-to-Grave
Includes full lifecycle through use and disposal. Required for consumer-facing disclosures and ISO 14067 verification.
Cradle-to-Cradle
Extends to circular material flows and recyclability.
Selecting the right boundary depends on regulatory requirements, customer expectations, and how the data will be used.
Why Now

Why Companies Are Calculating Product Carbon Footprints Now

Product carbon footprinting has shifted from a niche activity to a core business requirement. Companies are responding to a combination of regulatory pressure, customer demand, and internal decarbonization goals.
Customer Requirements
Enterprise buyers increasingly request PCFs as part of supplier qualification and procurement processes.
CSRD and EU Regulations
Product-level emissions data is required where material, supported by ISO 14067 methodology.
CBAM
Importers must report embedded carbon in regulated products entering the EU.
Digital Product Passports
Emerging requirements across electronics, textiles, and packaging.
Decarbonization Strategy
Product-level data identifies emissions hotspots and informs design and sourcing decisions.
For many organizations, product carbon footprinting is becoming as important as corporate emissions reporting.

If your customers are asking for product-level data, the expectation is not estimates. It is defensible, documented results.
