Oman's Yearly Greenhouse Gas Emissions in CO₂ Equivalent

Key Insights

Emissions Footprint Since 1850

Oman's greenhouse gas profile is dominated by more recent growth. Cumulatively, methane accounts for around 60% of the country's warming impact, with fossil CO2 contributing about 40%. Land-use change has been small overall and close to neutral, shifting between a slight sink and a minor source over time.

Methane’s Rise And Shift

From the mid-1960s to the early 2000s, methane emissions climbed rapidly from very low levels to the tens of megatonnes, driven largely by fugitive emissions. Since the turn of the century they have risen more slowly and stabilized at high levels. As this growth eased, the warming impact from methane declined sharply even while emissions edged up.

Fossil CO2 Growth Spurts

Fossil CO2 stayed low through the 20th century, then accelerated after 1990. The steepest surge came in the 2000s, when emissions roughly tripled by the early 2010s and then continued to rise to just over 80 megatonnes recently. Gas now makes up about 60% of fossil CO2 and has kept increasing, while oil-related emissions have leveled off. Nitrous oxide and fluorinated gases remain small but have trended upward.

Outlook And Priorities

Today's trajectory is shaped by two large sources: methane fugitive emissions and CO2 from gas. Stabilizing and then reducing these will determine Oman's near-term climate impact. Continued moderation in oil-related CO2 helps, but reversing the rise in gas and tackling methane losses are the decisive steps.

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.

  • CO2 Fossil Fuels and Industry (CO2 FFI)
  • CO2 Land-Use, Land-Use Change and Forestry (CO2 LULUCF)
  • 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.

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.

CO2 From Fossil Fuels and Industry

The sources are mostly fossil-fuel combustion emissions from coal, oil, and gas, as well as emissions from industrial processes such as cement production. Cement also absorbs CO2 out of the atmosphere through carbonation, which reduces emissions by about 0.8 Gt per year and is included here.

CO2 From Land-Use, Land-Use Change, and Forestry

The main driver of these emissions is deforestation, which includes logging and forest degradation, as well as other land-use change activities. The emissions also take into account the absorption of CO2 by processes that remove CO2 from the atmosphere, such as afforestation and reforestation. It is the net effect that is indicated here.

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.

About the Data

The last available year in all the emission datasets is 2023. CO2 emissions data is from the Global Carbon Project. It contains national CO2 emissions from fossil sources and land-use change. Emissions from CH4, N2O and F-gases come from the PRIMAP-Hist dataset. It is a rich dataset that combines several published sources to create a historical emissions time series for various greenhouse gases.

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.
