1. 6.1 1 UNFCCC – NAI SOFTWARE Sector: Energy Practical Aspects and Exercises CGE Greenhouse Gas Inventory Hands-on Training Workshop

2. 6.2 2 CONTENT Details on use of the UNFCCC – NAI Software to calculate and report GHG emissions in the Energy sector. Practical exercises (to be solved by the participants after the presentation).

3. 6.3 3 BACKGROUND The decision trees in the IPCC good practice guidance are used to choose a good practice method that suits national circumstances. The UNFCCC-NAI Software contains, basically, the methods of lesser complexity that countries can use to prepare their inventories. However, in principle, the software can be used to report the estimated emissions independently of the complexity of method used (Tier 2, 3, etc).
