NSOs must improve data and statistics required for GHG inventories in collaboration with agencies responsible for greenhouse gas inventories including energy, industry, transport, agriculture, waste, forestry and land use statistics. This is particularly the case for NSOs in Annex I Parties to UNFCCC with annual inventory reporting obligations, but NSO’s involvement would be helpful in all countries reporting on greenhouse gas inventories. To harmonize and streamline their work on GHG inventories, NSOs may wish to consider the following issues and actions:
| Name of the case | Country/Organization | Brief description | Results | Difficulties | Further information |
| Using official statistics to calculate GHG | Bosnia Herzegovina | NSO was not directly involved in climate-change agreements and implementation in the country; working with partners to establish GHG statistics | Publication of regular statistical releases “Greenhouse gas emissions from agriculture and waste sector” | - lack of understanding the importance and necessity of establishing environmental economic accounts in key institutions - lack of inter-institutional cooperation - the absence of a functioning network data management | PPT |
Increase the analytical usefulness of inventories with statistics | Canada | Statistics Canada recasts official Canadian GHG emissions data into GHG emissions accounts to provide users with a tool better suited to economic analysis. | The office explains the differences between the inventory concepts and the SEEA-CF concepts so there is no confusion among users. | - There are large conceptual differences between the inventories and official statistics. They need to be clearly explained to users. | PPT |
| Improving statistics for inventories with targeted measures | China | The National Bureau of Statistics of China has a work plan to strengthen its statistics to better measure climate change and especially greenhouse gas emissions | The work plan provides a useful example of planning work that involves many agencies | - unclear responsibilities between agencies may prevent progress, which is why this work plan was prepared in wide collaboration | Word |
| Workshop on Energy Data for Climate Policy | International Energy Agency, UNFCCC, UNEP Countries presenting in the workshop: Armenia, Georgia, Ghana, Malawi, | A joint IEA/UNEP/UNFCCC Workshop on Energy Data for Climate Policy took place on 25 & 27 November on line. The energy sector is key to overall national development and plays a fundamental role in combating climate change. The success of national energy and climate policies will rely on the ability of national systems to establish and maintain appropriate tracking procedures – which optimize data production and exchange across stakeholders from relevant national institutions. | The workshop discussed requirements on energy data for climate reporting and represented an opportunity for focal points from across institutions, both working on energy statistics and GHG inventories, to highlight good practices as well as barriers in establishing a coherent set of relevant data. | All workshop documents are available at the event website |
