GHG Inventory Overview
Taiwan has carried out the statistics and compilation of greenhouse gas inventory in accordance with the 2006 IPCC Guidelines. Greenhouse gases include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydro fluorocarbons (HFCs) and perfluorocarbons (PFCs) as well as sulphur hexafluoride (SF6) and nitrogen trifluoride (NF3). And the sources of emission and removal of Greenhouse gases are divided into five sectors, comprising Energy sector, Industrial Process and Product Use (IPPU) Sector, Agriculture Sector, Waste sector as well as Land use, land use change and forestry (LULUCF) sector.
GHG Emissions by Sector
Of all the sectors, the energy sector has long been the one accounting for the largest total greenhouse gas emission in Taiwan over the years. In 2005 and 2019, greenhouse gas emissions (excluding LULUCF) from energy sectors were responsible for approximately 85.99% and 90.80% of the total emissions, while the IPPU sector accounted for 10.12% and 7.10%, the agricultural sector accounted for 1.37% and 1.15%, and the waste sector accounted for 2.52 % and 0.94%.
The total greenhouse gas emission in Taiwan in 2019 decreased by 3.41% compared with 2018. In particular, the GHG emission from the energy sector was down by 3.14%, the IPPU sector was down by 7.21%, the agriculture sector was down by 1.38%, and the waste sector was down by 1.83%. Additionally, the carbon dioxide sequestration of the land use, land use change and forestry sector was down by 0.31%.
Compared to 2005(Base year), the emission in 2019 decreased by 1.20%. In particular, the GHG emission from the energy sector was up by 4.33%, the IPPU sector was down by 30.63%, the agriculture sector was down by 16.85%, and the waste sector was down by 63.12%. Additionally, the carbon dioxide sequestration of the land use, land use change and forestry sector was down by 2.18%.

GHG Emissions by Gas
Comparing statistics on various greenhouse gas emissions shows that carbon dioxide accounts for the majority of greenhouse gas emissions (excluding LULUCF) in Taiwan in 2005, accounting for 91.71%, followed by methane (3.27%), nitrous oxide (1.48%), and fluorinated greenhouse gas (3.54%). Carbon dioxide remains the largest of proportion (95.28%) in 2019, followed by nitrous oxide (1.71%), methane (1.67%), and then fluorinated greenhouse gas (1.34%).
The total greenhouse gas emission in Taiwan in 2019 decreased by 3.41% compared with 2018. In particular, carbon dioxide emissions decreased by 3.41%; methane emissions decreased by 2.15%; nitrous oxide emissions decreased by 3.69% and fluorinated greenhouse gas emissions decreased by 11.58%.
Compared to 2005(Base year), carbon dioxide emissions grew by 2.65%; methane emissions decreased by 49.66%; nitrous oxide emissions grew by 14.04% and fluorinated greenhouse gas emissions decreased by 62.51%.
National Inventory Report
The National Inventory Report of the Republic of China (Taiwan) carried out the statistics and compilation in accordance with the 2006 IPCC Guidelines to actively demonstrate the efforts and resolution to abide by the convention. The National Inventory Report (NIR) was firstly published in 2014 and updated annually. Taiwan has established a greenhouse gas inventory database covering the period from 1990 to 2019 in the NIR 2021 . The database provides an overview of greenhouse gas inventory statistics to reflect the GHG trends in Taiwan. It also aims to predict future greenhouse gas emissions and provide an overview of Taiwan's greenhouse gas emission trend.
