Methodological Issues

This section explains how to choose an approach, and summarises the necessary activity data and emission factors the inventory compiler will need. These sections are subdivided into Tiers as set out in Volume 1 General Guidance. The Tier 1 sections set out the steps needed for the simplest calculation methods, or the methods that require the least data. These are likely to provide the least accurate estimates of emissions. The Tier 2 and Tier 3 approaches require more detailed data and resources (time, expertise and country-specific data) to produce an estimate of emissions. Properly applied, the higher tiers should be more accurate.
