Definition

GHG Reporting Period is the temporal interval over which GHG Accounting reports cumulative GHG Emissions. In current protocols the time period of the GHG inventory cycle is typically 1 year but may be more (e.g., 2 or 4 years).

GPC Protocol

The GPC is designed to account for city GHG emissions within a single reporting year. The inventory shall cover a continuous period of 12 months, ideally aligning to either a calendar year or a financial year, consistent with the time periods most commonly used by the city.[1]

Calculation methodologies in the GPC generally quantify emissions released during the reporting year. In certain cases—in the Waste sector, for instance—the available or nationally-consistent methodologies may also estimate the future emissions that result from activities conducted within the reporting year
