Carbon Accounting

Definition

Carbon accounting is the systematic measurement and recording of an organisation's greenhouse gas emissions, following standardised methodologies — most commonly the GHG Protocol — to ensure figures are consistent, comparable, and auditable.

Carbon accounting typically separates emissions into three categories: Scope 1 (direct emissions from owned sources, such as company vehicles or on-site fuel combustion), Scope 2 (indirect emissions from purchased electricity, heat, or steam), and Scope 3 (all other indirect emissions across the value chain, such as purchased goods, business travel, and supply chain activity).

Accurate carbon accounting depends heavily on underlying energy consumption data — emissions are typically calculated by applying emissions factors to activity data (e.g., kWh consumed, litres of fuel burned), which is why organisations with poor energy monitoring often struggle to produce credible carbon accounts.

Why It Matters

Carbon accounting is now a formal regulatory requirement for many organisations under frameworks like CSRD, and even where it isn't mandatory, credible carbon figures are increasingly expected by customers, investors, and lenders. Inaccurate or estimated carbon accounting creates real reputational and compliance risk.

How ecolyptus Helps

ecolyptus's Sustainability Footprint feature automates emissions factor attribution across Scope 1 and 2 activity data pulled directly from connected meters and sites, producing auditable carbon reporting rather than manually compiled spreadsheet estimates.

Frequently Asked Questions

What's the difference between carbon accounting and carbon reporting?

Carbon accounting is the measurement and calculation process. Carbon reporting is the output — presenting those figures in a format required by a regulation, framework, or stakeholder.
