Oman's Progress and Recent Impact
Key Insights
Extremely High Per Capita Emissions
Oman's per capita greenhouse gas emissions are notably high, standing at 24.06 tonnes per person per year, which is classified as "extremely high" on the emissions scale. This level of emissions is significantly above the threshold of 10 tonnes per capita per year, indicating a substantial environmental impact relative to the country's population size. The high per capita emissions are largely driven by the country's reliance on fossil fuels, particularly natural gas, which accounts for a significant portion of the total emissions. This reliance is a legacy of Oman's historical development of its oil and gas industries, which have been central to its economic growth.
Significant Share of Global Emissions
In 2023, Oman contributed 111.74 megatonnes of CO2-equivalent emissions, representing 0.2026% of the global total. While this percentage might seem small, it is important to recognize that even minor contributors collectively have a significant impact on global emissions. Oman's emissions are primarily driven by fossil fuel combustion, with natural gas being the dominant source. The expansion of the natural gas industry in the 1980s and the subsequent development of industrial zones have played a crucial role in shaping the country's emissions profile.
Rising Emissions Trend
Over the past decade, Oman's total greenhouse gas emissions have been on an upward trajectory, with an annual increase of approximately 1.94%. This trend is concerning, as it contrasts with international goals to reduce emissions significantly to mitigate climate change. The increase is largely attributed to the continued growth in fossil fuel consumption, particularly in the industrial and transportation sectors. The development of industrial zones and the rise in vehicle ownership have further contributed to this trend, highlighting the challenges Oman faces in transitioning to a more sustainable energy model.
Background
Recent per Capita Emissions
The Recent per Capita Emissions are a crucial indicator of a nation's greenhouse gas emissions. They are a fair measure for comparing the emissions of nations, taking into account the size of their populations.
Because any greenhouse gas emissions above 0 cause warming, the per capita emissions shouldn't be judged against the global average; they should be compared based on how far they are above 0. Therefore, our rating scale is:
- Extremely High: above 10 tonnes per capita per year
- Very High: above 7.5 tonnes
- High: above 5 tonnes
- Moderate: above 2.5 tonnes
- Low: above 0 tonnes
- Negative Emissions: under 0
The per capita emissions should be close to zero for each country, indicated here by the green & low areas.
Last Year Emissions
This is the total amount of CO2, CH4, N2O, and F-Gases emissions of a nation in 2023 (last available year in the data) expressed in megatonnes of CO2-equivalents. The gases have different atmospheric lifetimes (decay) and warming effects, for this reason, we use the GWP100 (100 year time horizon method) to calculate the global warming potential of CH4, N2O, and F-Gases to express them in CO2-equivalents.
Wikipedia: Global Warming PotentialLast Year Share
This is a nation's share of the global emissions in 2023 (last available year in the data). For many countries this value can be quite small, especially when compared to nations like United States or China. It is easy and dangerous to jump to the conclusion that small shares of emissions don't matter. They matter as a group. Even small emitters can account for a significant amount of total emissions. Consider the following examples:
- 24 nations, each between 0.5 and 1.5% of the total emissions, make up 20% of the total emissions.
- 27 nations, each between 0.5 and 2% of the total emissions, make up 25% of the total emissions.
- 162 nations with a share below 0.5% make up 15% of the total.
- 3 nations, make 44% of the total emissions: China, United States and India. However, China and India together have a population of about 2.9 billion.
Per Capita Emissions are therefore the most crucial indicator to represent the impact of a nation regardless of its size.
Yearly Emissions Trend
This is a nation's trend per year over the last 10 years. It is a good indicator of the trajectory of national emissions and can be used as a simple framework to judge a nation's trend vs. international goals:
- Stop warming around 1.5 °C: All nations together, and each nation, should drop emissions by 17% per year — 8,000 Megatonnes of CO2 Equivalent per Year.
- To achieve Net Zero in 2050 and to stop warming at ~1.7 °C: All nations should together, and each nation, should drop emissions by 4% per year — 2,100 Megatonnes of CO2 Equivalent per Year.
- Additionally, to return warming to pre-industrial levels almost all human-induced CO2 has to be taken out of the atmosphere.
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. Population data are also from Global Carbon Project where available, however, for many nations it doesn't have historic population going back to 1850. Those historic gaps are filled with population data from Our World in Data.
