Indonesia's Yearly Greenhouse Gas Emissions in CO₂ Equivalent
Key Insights
2024 Emissions Profile
In 2024, Indonesia's CO2 emissions were around 1,420 megatonnes CO2, 74.5% of the national total, and fell by about 46 megatonnes CO2 per year over the ten years to 2024. Methane reached roughly 394 megatonnes CO2e, or 20.7%, rising by about 12 megatonnes CO2e annually. N2O was around 71 megatonnes CO2e (3.7%) and F-gases 21 megatonnes CO2e (1.1%); both were increasing. CO2 dominated emissions, with methane a substantial second-largest gas.
Historic Carbon Dioxide (CO2) Emissions
CO2 emissions began at roughly 140 megatonnes CO2 in 1851 and rose gradually to around 360 by the mid-1950s. Growth then accelerated markedly, reaching a record peak of nearly 2,780 megatonnes CO2 in 1997. Emissions subsequently declined overall, ending at around 1,420 megatonnes CO2 in 2024.
Historic Methane (CH4) Emissions
Methane emissions rose from around 17 megatonnes CO2e in 1851 to roughly 84 by the mid-1960s, then continued upward to about 215 in 2006. Growth accelerated thereafter, with emissions peaking at nearly 395 megatonnes CO2e in 2023 before ending near 394 in 2024. Methane's warming contribution since 1851 was around 88% larger than its emissions alone suggest, because methane's short atmospheric lifetime amplifies the warming impact when CH4 emissions are rising.
Historic Nitrous Oxide (N2O) Emissions
N2O emissions were below 1 megatonne CO2e in 1851 and rose steadily throughout the record. Growth became faster after the mid-1970s, increasing from around 21 megatonnes CO2e to a peak of nearly 72 in 2020. Emissions eased slightly thereafter, ending at roughly 71 megatonnes CO2e in 2024.
Historic Fluorinated Gases (F-gases) Emissions
F-gas emissions were near zero until the mid-20th century, reaching only around 0.4 megatonnes CO2e by 1957. They increased gradually to roughly 3.5 by 2001, then rose much faster. Emissions reached their record high of around 21 megatonnes CO2e in 2024.
Background
Greenhouse gas emissions from human activities are the main drivers of human-induced warming. In the scientific literature, human-induced emissions are often referred to as anthropogenic emissions.
- Carbon Dioxide (CO2)
- Methane (CH4)
- Nitrous oxide (N2O)
- Fluorinated gases (F-gases)
Emissions from all different gases are expressed in CO2-equivalent units to make it possible to compare the relative emissions from these different gases. CO2-equivalents are calculated using the global warming potentials of the respective gases, in this case using a 100-year time horizon.

Crabon Dioxide (CO2)
CO2 includes emissions from fossil fuels and industry (FFI), and from land-use, land-use-change, and forestry (LULUCF).
Methane (CH4)
Methane emissions are caused by human activities such as rearing livestock, agricultural practices, and fugitive fossil fuel emissions.
Nitrous Oxide (N2O)
Common sources of these emissions are fossil fuel emissions and the agricultural use of synthetic fertilizer and manure.
Fluorinated Gases (F-gases)
Fluorinated gases are a group of gases defined by UNFCCC: hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF6), and nitrogen trifluoride (NF3). Fluorinated gases are also known as halogenated gases.

Units and Measures
CO2-equivalent emissions are expressed in the total weight in megatonnes per year. 1 Megatonne is equal to 1 million tonnes.

National CO2 emissions data through 2024 is from the Global Carbon Project and covers fossil sources and land-use change. Emissions data through 2024 for CH4, N2O and F-gases comes from the PRIMAP-hist dataset, which combines several published sources into historical emissions time series.
The Key Insights paragraph was created using a large language model (LLM) in combination with our data, historic events, and a structured approach for best accuracy by separating the context generation from the interpretation and narrative.
