Product Carbon Footprint

This guide explains how to use Carbon GPT to calculate, report, and reduce the carbon footprint of your products throughout their lifecycle.

Introduction to Product Carbon Footprinting

  • Definition and importance of product carbon footprints
  • Difference between organizational and product footprints
  • Business benefits of product carbon assessment
  • Regulatory drivers and market trends

Methodological Approaches

Life Cycle Assessment (LCA) Basics

  • Cradle-to-grave vs. cradle-to-gate approaches
  • System boundaries and scope definition
  • Functional units and reference flows
  • Allocation methods for multi-output processes

Standards and Frameworks

  • GHG Protocol Product Standard
  • ISO 14067 (Carbon Footprint of Products)
  • PAS 2050
  • Product Environmental Footprint (PEF)
