Corporate carbon footprint
The corporate carbon footprint is an organisation-wide greenhouse gas inventory for a reporting year that reports direct and indirect emissions across Scope 1, 2 and 3 in CO2 equivalents.
The corporate carbon footprint (CCF) quantifies all greenhouse gas emissions attributable to an organisation within a reporting period, usually a financial year. Its reference unit is the company as a whole rather than an individual product. Methodologically it rests on the Greenhouse Gas Protocol Corporate Accounting and Reporting Standard and on ISO 14064-1. Both split emissions into Scope 1 (direct emissions from owned or controlled sources such as boilers, process plants and the vehicle fleet), Scope 2 (indirect emissions from purchased energy including electricity, heat, cooling and steam) and Scope 3 (all other indirect emissions across the upstream and downstream value chain).
The credibility of a CCF depends far less on the arithmetic – activity data multiplied by emission factors and converted into CO2 equivalents – than on carefully drawn boundaries. Organisations must set their organisational boundaries (equity share, or the financial or operational control approach), their operational boundaries, meaning which of the fifteen Scope 3 categories are treated as material, and a consistent base year together with rules for recalculating it after acquisitions, divestments or methodology changes. For Scope 2 the GHG Protocol additionally requires dual reporting under the market-based and the location-based method. Assumptions, data sources and uncertainties must be documented so that the inventory withstands external assurance.
The CCF differs from the product carbon footprint (PCF) in reference unit, system boundary and governing standard. A PCF follows ISO 14067 or the GHG Protocol Product Standard, assesses the emissions of a functional unit – a component or a pack, for instance – across its life cycle, and relies on life-cycle process data. The CCF, by contrast, is a period-based organisational inventory. The two figures cannot be converted into one another, yet they complement each other: supplier PCF data improve the quality of the Scope 3 category "purchased goods and services", while the CCF provides the quantitative basis for climate disclosures under ESRS E1 within the CSRD framework, for science-based reduction targets and for the transition plan.
Legal Basis
ESRS E1 (Commission Delegated Regulation (EU) 2023/2772 under Directive (EU) 2022/2464 – CSRD); GHG Protocol Corporate Accounting and Reporting Standard; EN ISO 14064-1; distinguished from the PCF under EN ISO 14067
Practical Example
An automotive supplier with four plants compiles its first CCF. The sustainability manager selects the operational control approach, which leaves a joint venture without operational control outside the boundary, and sets 2024 as the base year. Scope 1 draws on natural gas, heating oil and fuel invoices plus refrigerant top-up quantities; Scope 2 uses meter readings and the guarantees of origin attached to the electricity contracts, reported separately on a market-based and a location-based basis. A screening of the fifteen Scope 3 categories identifies purchased goods, transport and employee commuting as material. For steel and aluminium parts the manager requests product-level PCF figures under ISO 14067 from the main suppliers, gradually replacing the spend-based average factors used at first. Assumptions and data sources are recorded per category so the assurance provider can retrace the ESRS E1 disclosures.
