The Central Statistics Agency (BPS) compiled carbon dioxide (CO2) emissions from energy use in Indonesian business sectors and households from 2017 to 2021.
For all business sectors, CO2 emissions in 2017 reached 456,932,000 tons. The following year, emissions increased sharply to 548,368,000 tons.
In 2019, emissions further increased to 593,715,000 tons. However, in 2020, CO2 emissions from all business sectors decreased to 535,453,000 tons. In 2021, the latest data available, emissions increased slightly to 536,830,000 tons.
BPS stated that the electricity and gas supply subsector was the largest contributor to CO2 emissions in Indonesia during the 2017-2021 period, accounting for over 50% of total CO2 emissions from all business sectors each year.
"This is because this business sector also uses energy for energy transformation, resulting in relatively higher CO2 emissions," wrote BPS in its report, *Indonesia's Energy Flow Balance and Greenhouse Gas Emission Balance*.

CO2 emissions from this business sector have shown a consistent upward trend.
"In 2021, CO2 emissions from the electricity and gas supply business sector increased by 24.45% compared to 2017," BPS wrote.
Meanwhile, CO2 emissions from the household sector fluctuated. In 2017, emissions amounted to 72,608,000 tons. This figure rose to 77,045,000 tons in 2018.
In 2019, emissions from this sector further increased to 82,546,000 tons. In 2020, they decreased to 79,346,000 tons. However, in 2021, emissions increased again to 82,025,000 tons.
Although these two sectors contributed vastly different volumes, both experienced a decrease in emissions in 2020, during the COVID-19 pandemic.
"In 2020, CO2 emissions from Indonesian households decreased to 79,346,000 tons due to reduced energy use for private transportation, which was limited by the COVID-19 pandemic," BPS wrote in its report.
