Mercury or Hg is a heavy metal that exists in a liquid state and is widely used in both industrial processes and daily life. Unfortunately, mercury has a high level of toxicity to living organisms and is difficult to degrade, which can lead to environmental pollution. UNEP, as a global institution, is working to reduce and eliminate the use of mercury in order to minimize its negative impacts. Indonesia is actively involved in ratifying the Minamata Convention and demonstrates its commitment through the establishment of a National Action Plan (NAP) to manage the use, storage, disposal, and replacement of mercury in Indonesia. This study conducts an inventory to determine the amount of mercury present in Indonesia. The mercury inventory is carried out using the UNEP Hg Level 1 Toolkit. Additionally, a comparison is made between the use of the Level 1 Toolkit in the current calculations and the calculations from a previous study conducted in 2015. There are differences in the use of the UNEP Hg Toolkit between the 2015 and 2021 calculations, such as changes in activity details, default input factor values in the calculations, assumptions used, and an increase in the released mercury from 389,060 kg Hg in 2015 to 553,610 kg Hg in 2021. The results of this inventory can be used as a proposal to enhance mercury management in Indonesia as a followup to the development of the NAP.
