GHG Accounting
Contents
Definition
GHG Accounting. A means of measuring the direct and indirect emissions to the Earth’s Biosphere of CO2 and its equivalent gases from industrial activities
Principles
The GHG Protocol[1] Principles stipulate:
Relevance
Ensure the GHG Inventory appropriately reflects the GHG Emissions of the company and serves the decision-making needs of users - both internal and external to the company
Completeness
Account for and report on all GHG emission sources and activities within the inventory boundary. Disclose and justify any specific exclusions.
Consistency
Use consistent methodologies to allow for meaningful performance tracking of emissions over time. Transparently document any changes to the data, inventory boundary, methods, or any other relevant factors in the time series.
Transparency
Address all relevant issues in a factual and coherent manner, based on a clear audit trail. Disclose any relevant assumptions and make appropriate references to the accounting and calculation methodologies and data sources used.
Accuracy
Ensure that the quantification of GHG emissions is systematically neither over nor under actual emissions, as far as can be judged, and that uncertainties are reduced as far as practicable. Achieve sufficient accuracy to enable users to make decisions with reasonable confidence as to the integrity of the reported information.
