1. Discussion Session 1: Official statistics and Greenhouse gas inventories

2. UK National Inventory System National Statistical Office coordinates the work of the Single National Entity Some benefits include – independence and impartiality of emissions data – quality assurance in the publication of GHG estimates – Improved communication of GHG emissions data – direct integration into strategy (UK carbon budgets), projections and policy

3. How many different calculations using emission factors? What produces more emissions annually – cattle, cars or collieries? GHG emissions come from a multitude of sources (not just power stations!) Quiz!

4. Questions 1.How to ensure National Statistical Systems are more aware of how their data are, or could be, used in inventories? 2.Should National Statistical Systems be more involved in National Inventory Systems? 3.What roles and responsibilities should the UNFCCC, UNECE or other international organisations have?

5. Supplementary Questions 1.What actions are needed to improve data quality? 2.Is precision (in inventories) proportional to the emissions contribution of the source category? 3.Is it realistic to demand more from National Statistical Systems? What are the challenges to this? 4.What is the impact on non-Annex 1 Parties of increasing the sophistication of NIS? 5.Do inventories require differing sectoral approaches with respect to National Statistical Systems? 6.How to share best practice?
