Romania's Yearly Greenhouse Gas Emissions in CO₂ Equivalent
Key Insights
2024 Emissions Profile
In 2024, Romania's emissions were dominated by CO2, at around 58 megatonnes CO2 and 62.9% of the national total. Methane contributed around 21 megatonnes CO2e (22.6%), followed by nitrous oxide at roughly 10 megatonnes CO2e (11.0%) and F-gases at around 3.4 megatonnes CO2e (3.6%). Over the ten years to 2024, CO2 and methane declined, while nitrous oxide and F-gases increased.
Historic Carbon Dioxide (CO2) Emissions
CO2 emissions began at roughly 14 megatonnes CO2 in 1851 and varied at relatively low levels through the early twentieth century. They rose sharply after the early 1950s, peaking at about 221 megatonnes CO2 in 1987. Emissions then declined substantially, reaching around 58 megatonnes CO2 in 2024.
Historic Methane (CH4) Emissions
Methane emissions rose from around 10 megatonnes CO2e in 1851 to roughly 28 megatonnes CO2e by the mid-1930s, before falling around 1950. They increased again through the late twentieth century, peaking at about 41 megatonnes CO2e in 1985, then declined to around 21 megatonnes CO2e in 2024. Methane's warming contribution since 1851 was around 20% smaller than its emissions alone suggest, because methane's short atmospheric lifetime dampens the warming impact when CH4 emissions are falling.
Historic Nitrous Oxide (N2O) Emissions
Nitrous oxide emissions were below 1 megatonne CO2e in 1851 and remained low into the early twentieth century. They climbed rapidly after 1945, peaking at around 21 megatonnes CO2e in 1981, then fell sharply during the 1980s and 1990s. They subsequently stabilised near 10 megatonnes CO2e, ending at around 10 megatonnes CO2e in 2024.
Historic Fluorinated Gases (F-gases) Emissions
F-gas emissions were negligible in 1851 but became more substantial after the 1920s, rising to a peak of around 4.3 megatonnes CO2e in 1981. They fell sharply to roughly 1.7 megatonnes CO2e by 1992, then recovered unevenly. Emissions reached around 3.4 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.
