View source for Global Protocol for Community-Scale Greenhouse Gas Inventories

== Definition ==
The '''Global Protocol for Community-Scale Greenhouse Gas Inventories''' (GPC) is a [[GHG Accounting]] and Reporting Standard for Cities. <ref>Global Protocol for Community-Scale Greenhouse Gas Inventories, An Accounting and Reporting Standard for Cities, Version 1.1, 2021. WRI, C40, IOCLEI</ref>. 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.

== Compliance ==
The GPC uses precise language to indicate which provisions of the standard are requirements, which are recommendations, and which are permissible or allowable
options that cities may choose to follow.
