Algeria's Progress and Recent Impact
✨ Key Insights
High Per Capita Emissions
Algeria's recent per capita greenhouse gas emissions are rated as "high," with a value of 5.58 tonnes per person per year. This level of emissions is significantly above the ideal target of zero, indicating a substantial environmental impact per individual. The high per capita emissions are largely driven by the country's reliance on fossil fuels, particularly natural gas and oil, which together account for a significant portion of the total emissions. The historical development of Algeria's hydrocarbon sector, including the nationalization of oil and gas resources and the expansion of Sonatrach operations, has contributed to this high level of emissions.
Rising Total Emissions
In 2023, Algeria's total greenhouse gas emissions reached 254.44 megatonnes of CO2-equivalents, representing 0.46% of the global total. This figure underscores Algeria's role as a notable emitter on the global stage, despite its relatively small share. The country's emissions have been on an upward trajectory, with a 1.63% annual increase over the past decade. This trend is primarily driven by the fossil fuel sector, with natural gas and oil being the main contributors. The launch of projects like the In Amenas gas project and the start of LNG exports have further fueled this increase.
Methane and F-Gases Contributions
Methane emissions, primarily from fugitive emissions in the energy sector, and F-gases, though smaller in volume, have also contributed to Algeria's overall emissions profile. The expansion of natural gas production and the development of shale gas reserves have led to increased methane emissions. Meanwhile, F-gases, used in industrial applications, have shown a notable percentage increase, reflecting industrial growth. These gases, while not as voluminous as CO2, have a high global warming potential, making their management crucial for Algeria's climate strategy.
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.
