The international statistical community, including national statistical systems and international statistical organisations, should take an active role in contributing to the global GHG inventory system

The international statistical community, including national statistical systems and international statistical organisations, should take an active role in contributing to the global GHG inventory system. The standards, classifications and methods of greenhouse gas inventories and official statistics are developed and agreed upon in international processes. Therefore, a better dialogue among the statistical community and organisations working on climate issues would be beneficial. The international statistical community and NSOs may wish to consider the following issues and actions:

  • Seek closer collaboration between the statistical community and international organisations working on climate issues
  • Actively engage, at national level, with the national representatives delegated to the relevant UNFCCC forums
  • Follow up on the outcomes of the UNFCCC conferences of the parties to the convention
  • Involve NSOs at the outset of work when countries need to respond to new data needs from the convention
  • Existing international networks of NSOs could facilitate the exchange experience

Requirements and capacity-building needs of the UNFCCC process (IPCC)IPCCDescription of difficulties with activity data collection; importance of involving statistical offices in GHG inventory preparation; and good practice in data collection for GHG inventory compilation

Statistical offices can better contribute to national GHG inventory compilation by enhancing the capacities to do the following:
- Focus on the collection of data needed to improve estimates of key categories which are the largest, have the greatest potential to change, or have the greatest uncertainty.
- Choose data collection procedures that iteratively improve the quality of the inventory in line with the data quality objectives.
- Collect data/information at a level of detail appropriate to the method used.
- Collect uncertainty information as well when collecting data.

Individual data providers are not aware of GHG inventories and not willingness to provide data for production of GHG inventory.
- Lack of a legal framework that mandates the provision of data
- Inadequate institutional arrangements to ensure data collection

Pollutant Release and Transfer Registers (PRTR)UNECEThe register includes data reported by companies on emissions — such as greenhouse gases and heavy metals — from industrial sites and other sources to national PRTRs that are publicly accessible and searchable through the Internet.PRTRs allow free web-based access to geo-referenced data on industrial pollutants, including GHG emissions, to help the public, decision makers, scientists and journalists make informed choices.- Further work is needed to use the PRTRs for reporting to UNFCCC. Norway and Japan already make use of PRTR data for that and Finland is comparing the results from bottom-up calculations to top-down estimation of GHG emissions. Portal
