The Basics

As an expert, you are probably familiar with the process of preparing a greenhouse gas inventory for submission under the UNFCCC (although requirements for Annex I Parties may be less familiar to you). Essentially, the process can be summarized by the four fundamentals:

Methods
Data
National Inventory Process (institutional arrangements/system), and
Transparency (documentation).

The most important fundamental to you as a reviewer is the quality of the documentation (transparency) provided by the Party because without good documentation, it is not possible to conduct a thorough review.

A highly transparent national inventory will also be rigorous and honest in addressing its weaknesses.

Parties should maintain a documentation archive. Parties are also encouraged to publish the documentation used in for their inventories (for example on the internet).
