Eswatini's Progress and Recent Impact
Key Insights
Low Per Capita Emissions
Eswatini's recent greenhouse gas emissions per capita are rated as low, with a value of 2.2151 tonnes per person per year. This places the country in the lower range of emissions compared to global standards, indicating a relatively modest impact on climate change per individual. The low per capita emissions are a positive sign, suggesting that Eswatini is managing its emissions effectively relative to its population size.
Methane and Agriculture
A significant portion of Eswatini's emissions comes from methane, primarily driven by agricultural activities. Livestock farming, which expanded around the year 2000, is a major contributor to methane emissions due to enteric fermentation. The sugar industry, which saw significant growth in the 1980s, also plays a role in methane emissions through biomass burning and decomposition. These agricultural practices highlight the importance of sustainable farming techniques in managing emissions.
Fossil Fuels and Energy
Fossil fuel emissions, particularly from oil, account for a substantial part of Eswatini's greenhouse gas profile. The country's reliance on oil for energy is evident, although there has been a positive shift towards renewable energy projects since 2010. These initiatives aim to reduce fossil fuel dependency and lower CO₂ emissions, reflecting Eswatini's commitment to sustainable development and climate change mitigation.
Emissions Trend and Future Outlook
Over the past decade, Eswatini's total greenhouse gas emissions have shown a slight upward trend, with an annual increase of 1.09%. This trend suggests a need for continued efforts in emissions reduction, particularly in the energy and agricultural sectors. The country's investment in renewable energy projects is a promising step towards a more sustainable future, but further action is needed to align with international climate goals and reduce emissions more significantly.
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.
