Operate in a safe, secure, sustainable and efficient manner
RELEVANCE Ensure inventory appropriately reflects the 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 emission sources and activities within the chosen inventory boundary. Disclose and justify any specific exclusions.
CONSISTENCY Use consistent methodologies. 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 neither under or overstated and that uncertainties are reduced as far as practicable. Achieve sufficient accuracy to enable users to make decisions with reasonable assurance as to the integrity of the reported information.
Two standards available:
ISO14064-1 “Specification with guidance at the organizational level for quantification and reporting of greenhouse gas emissions and removals” 2006.
“Greenhouse Gas Protocol - A Corporate Accounting and Reporting Standard Revised” World Business Council for Sustainable Development (WBCSD) and World Resources Institute (WRI) 2007
Setting Organizational Boundaries
Equity share approach
Under the equity share approach, a company accounts for GHG emissions from operations according to its share of equity in the operation.
Under the control approach, a company accounts for 100 percent of the GHG emissions from operations over which it has control (financial or operational).
Setting Operational Boundaries
Have to be comprehensive with respect to:
Direct GHG emissions - emissions from sources that are owned or controlled by the company.
Indirect GHG emissions - emissions that are a consequence of the activities of the company but occur at sources owned or controlled by another company.
Setting Operational Boundaries
Scope 1: Direct GHG emissions
Direct GHG emissions occur from sources that are owned or controlled by the company, for example, emissions from combustion in owned or controlled boilers, furnaces, vehicles.
Scope 2: Electricity indirect GHG emissions
Scope 2 accounts for GHG emissions from the generation of purchased electricityconsumed by the company. Purchased electricity is defined as electricity that is purchased or otherwise brought into the organizational boundary of the company. Scope 2 emissions physically occur at the facility where electricity is generated.
Scope 3: Other indirect GHG emissions
An optional reporting category that allows for the treatment of all other indirect emissions. Scope 3 emissions are a consequence of the activities of the company, but occur from sources not owned or controlled by the company. Some examples of scope 3 activities are extraction and production of purchased materials; transportation of purchased fuels; and use of sold products and services.
