How do Scope 1, 2, and 3 emissions relate to PCF?

A product’s carbon footprint is shaped by emissions across Scope 1, Scope 2, and Scope 3, as defined by the GHG Protocol. Understanding these scopes is essential for building accurate and transparent Product Carbon Footprints (PCFs):

• Scope 1 includes direct emissions from owned or controlled sources, such as manufacturing facilities, machinery, or onsite fuel combustion.
• Scope 2 covers indirect emissions from purchased energy — including electricity, heating, cooling, or steam — used during production.
• Scope 3 represents all other indirect emissions across the value chain, including raw material extraction, supplier activities, logistics, product use, and end-of-life treatment. For most products, Scope 3 accounts for the largest share of total emissions.

Sustamize helps companies quantify emissions across all three scopes by providing verified, lifecycle-based CO₂e datasets and standardized methodologies. This ensures accurate PCF calculations, greater transparency in supplier data, and alignment with ISO 14067 and GHG Protocol requirements.
