Institutional arrangement for the GHG Inventory preparation

Main tasks of GIO

Objective of Establishing GIOThe Greenhouse Gas Inventory Office of Japan (GIO) was established in July 2002 at the Center for Global

Environmental Research (CGER), the National Institute for Environmental Studies (NIES) to compile annual greenhouse gas (GHG) inventories, to conduct related research, and to execute related tasks such as international correspondence.

［Domestic activities］

［International activities］

The Greenhouse Gas Inventory Office of Japan (GIO) develops the GHG inventory in cooperation with private consultant companies under a contract with the Ministry of the Environment (Figure 3). Before preparing GHG inventories, GIO collects data from relevant ministries, agencies and organizations to estimate emissions and removals. Based on these data together with other data from different publications, GIO then compiles the GHG inventory. This compiled inventory is annually submitted to the UNFCCC Secretariat through the Japanese Government. This inventory serves as the official data which are reported internationally.

"Japan’ s National Greenhouse Gas Emissions in Fiscal Year 2016" shown below is the output of GIO’ s GHG inventory compilation work.

What is a GHG Inventory?An emission inventory is an accounting of the

amount of emissions of specific substances (such as air polluting substances and harmful chemicals) during a certain period of time. A greenhouse gas inventory is such an emission inventory. It reports the amount of emissions and removals of gases that cause global warming (greenhouse gases) such as carbon dioxide (CO2), by sources and sinks.

For GHG inventories, the emissions for each gas are calculated for each sector and source category (see Table 1), based on statistics rather than actual measurement data, as shown in Figure 2. These estimates are summarized in a Common Reporting Format (CRF), which, together with emission estimates and estimation methods documented in the National Greenhouse Gas Inventory Report (NIR), will become the official national GHG inventory.

Unde r t he UNFCCC , an i n t e rna t i ona l environmental treaty to address global warming issues, developed countries and Eastern European countries including Russia (Annex I parties) are required to submit annual national GHG inventories to the UNFCCC Secretariat.

　　Japan’ s total greenhouse gas emissions in fiscal year (FY) 2016 were 1,307 million tonnes of carbon dioxide (CO2) equivalents (Mt CO2 eq.) (Figure 4). 　　This is a decrease of 1.2% (16 Mt CO2 eq.) and 7.3% (103 Mt CO2 eq.) when compared to the FY2015 and FY2013 emissions (1,323 Mt CO2 eq. and 1,410 Mt CO2 eq.) respectively, mainly because of the decrease in energy-related CO2 emissions due to the decrease in energy consumption through energy conservation, and the increase in the share of non-fossil fuels within the domestic energy supply brought by the wider adoption of solar and wind power and resumption of nuclear power plant operation, despite the increase in hydrofluorocarbon emissions from refrigerants that substitute for ozone-depleting substances. This is also a decrease of 5.2% (72 Mt CO2 eq.) when compared to the FY2005 emissions (1,379 Mt CO2 eq.), mainly due to the decrease in energy-related CO2 emissions owing to the decrease in energy consumption through energy conservation, despite the increase in hydrofluorocarbon emissions from refrigerants that substitute for ozone-depleting substances.
