Definition
The Global Protocol for Community-Scale Greenhouse Gas Inventories (GPC) is a GHG Accounting and Reporting Standard for Cities. [1]. The GPC can be used by anyone assessing Greenhouse Gas Emissions of a geographically defined, subnational area.
Structure
The GPC is divided into three main parts:
- Part I introduces the GPC reporting and accounting principles, sets out how to define the inventory boundary, specifies reporting requirements and offers a sample reporting template
- Part II provides overarching and sector-specific accounting and reporting guidance for sourcing data and calculating emissions, including calculation methods and equations
- Part III shows how inventories can be used to set mitigation goals and track performance over time, and shows how cities can manage inventory quality
Objectives
The GPC seeks to:
- Help cities develop a comprehensive and robust GHG Inventory in order to support climate action planning.
- Help cities establish a base year inventory (Base Year GHG Emissions), set reduction targets (GHG Emissions Target), and track their performance.
- Ensure consistent and transparent measurement and reporting of GHG emissions between cities, benchmarking performance, following internationally recognized GHG accounting and reporting principles.
- Enable city inventories to be aggregated at subnational and national levels.
- Demonstrate the important role that cities play in tackling climate change, and facilitate insight through benchmarking - and aggregation - of comparable data.
