Global data collection

The global data collection for the System of Environmental-Economic Accounting (SEEA) focuses on the Physical Energy Flow Accounts (PEFA) and Air Emission Accounts (AEA) and marks an important achievement for the United Nations Committee of Experts on Environmental-Economic Accounting (UNCEEA) towards the establishment of global databases for the System of Environmental-Economic Accounting (SEEA). 

The questionnaires, developed under the auspices of the UNCEEA, are fully consistent with the SEEA and were developed on the basis of existing Eurostat PEFA and AEA questionnaires but tailored to fit the circumstances of countries with different levels of data availability. In particular, each questionnaire contains three different templates which correspond to different levels of data disaggregation.

Data from the questionnaires will be disseminated through a database maintained by UNSD, thereby providing easy access to high-quality, comparable official statistics relevant for climate change and energy policy. It is also important to mention that the questionnaires will serve the purposes of the Group of Twenty (G20) new Data Gaps Initiative (DGI), which aims to close climate change data gaps (among others) using SEEA PEFA and AEA. As the methodology behind the DGI is still being developed, it should be noted that there may be small additions to the PEFA and AEA questionnaires in the future. 

You can download the questionnaires below.
