GHG accounting and PCF
Product and process Carbon clarity
Greenhouse Gas (GHG) Accounting forms the backbone of any credible climate action plan. It is the first step in understanding your organisation’s environmental impact and the foundation upon which net-zero strategies, climate disclosures, and emissions reduction efforts are built. From regulatory compliance and investor expectations to supply chain pressure and brand positioning, accurate emissions data is now a core business need.
At SAGE, we support you in calculating your emissions across Scope 1, 2, and 3 categories using globally recognised protocols such as the GHG Protocol and ISO 14064. We help you collect reliable activity data, apply appropriate emission factors, address data gaps, and develop systems that are audit-ready and future-proof.
For businesses seeking deeper insights, we also calculate Product Carbon Footprints (PCF), which attribute emissions to a per-unit or per-product basis. This level of detail enables better product design, differentiation in carbon-conscious markets, and informed pricing strategies. PCF is especially valuable in sectors such as manufacturing, textiles, packaging, and consumer goods where low-carbon innovation is becoming a competitive edge.
Our GHG and PCF assessments are designed to be technically rigorous, aligned with disclosure frameworks such as CDP, SBTi, and BRSR, and tailored to your operational realities. We go beyond carbon numbers. We help you use them to drive decisions, meet expectations, and chart a clear path toward decarbonisation.
FAQ's
What is the difference between GHG accounting and PCF?
GHG accounting captures organisational emissions (Scope 1, 2, 3), while PCF refers to emissions associated with a single unit of product, from raw materials to delivery or disposal.
Which standards do you follow for GHG accounting?
We align with the GHG Protocol (Corporate, Scope 3, and Product Standards), ISO 14064, and industry-specific methodologies such as PACT, SBTi, and BRSR.
Why should we calculate Scope 3 emissions?
Scope 3 includes upstream and downstream emissions often representing over 70% of your total footprint. Understanding these is key to supply chain engagement and credible targets.
Is PCF needed only for exports?
No. PCF is now increasingly sought even in domestic procurement, especially in sectors such as auto, FMCG, textiles, and construction.
Can this link to net-zero planning or SBTi?
Absolutely. Our carbon accounting is designed to form the foundation for target-setting, mitigation planning, and SBTi alignment.
