What is a PCF?
A Product Carbon Footprint (PCF) measures the total greenhouse gas emissions associated with a product throughout its lifecycle, expressed in kilograms of CO2-equivalent (kg CO2e). The scope of a PCF depends on the boundaries of the assessment.
A PCF also breaks down the greenhouse gas emissions of the product into five categories: biogenic emissions, biogenic removals, aircraft emissions, emissions from land use, and fossil fuel usage. This helps communicate both the environmental impact of the product and the main drivers of its impact in one “standardized” format.
What are PCFs for?
PCFs have become increasingly common as businesses work to enhance transparency in sustainability and achieve their sustainability goals. They help businesses:
- Comply with Regulations: Helping businesses meet government regulations related to emissions and environmental impact.
- Fulfill Customer Requests: Providing customers with clear transparency about the environmental footprint of their products.
- Differentiate Brand Image: Strengthening a company’s brand by highlighting its commitment to sustainability.
- Meet Shareholder Expectations: Demonstrating a proactive sustainability approach, which can increase shareholder confidence and align with investor priorities.
- Add to Scope Accounting: Supporting the management of Scope 3 emissions and integrating emissions data into a company’s broader sustainability strategy.
PCF Standards Explained
There are many different standards that apply to PCFs, depending on the application. Some common standards include:
- PACT’s Pathfinder Framework (2023)
- ISO 14067 (2018)
- GHG Protocol’s Product Standard (2011)
- PAS 2050 (2008)
These standards all share foundational principles from ISO 14040 and ISO 14044, which define Life Cycle Assessment (LCA) methodologies. However, key differences in scope, flexibility, and data requirements mean that it isn’t important to follow each standard simultaneously. Some standards (e.g., PAS 2050, PACT) enforce stricter methodologies, while others (e.g., ISO 14067) allow more flexibility. Choosing the right standard at the beginning is essential to ensure consistent calculations, comparability, and compliance with regulatory or market expectations.
