Botswana's Progress and Recent Impact

Key Insights

Extremely High Per Capita Burden

Botswana's latest greenhouse gas emissions total 26.8 megatonnes in 2024, a small 0.05% share of the global total but with a striking national footprint: 10.6 tonnes per capita per year, rated as extremely high. This underscores that, regardless of global share, the average individual footprint is far above the level compatible with stopping additional warming.

Agriculture Dominates Non-CO2 Emissions

The emissions profile leans toward non-CO2 gases. Methane contributes roughly two-fifths of national emissions, driven largely by crop-related sources, while nitrous oxide adds close to a third, predominantly from agriculture. These two gases together form the majority of the total and have been expanding more rapidly over the decade than other components, making them central to the country's trajectory.

Fossil CO2 And Other Sources

Fossil CO2 accounts for a little over a quarter of total emissions, with coal the largest contributor and oil next. This segment has grown, but at a slower pace than methane and nitrous oxide. Land-use CO2 is a small, rising source, and F-gases remain minor yet trending upward.

Rising Decade-Long Trend

Over the past decade, total emissions have climbed steadily by about 1.4 megatonnes per year-roughly an 8% rise relative to the decade's average each year. This direction contrasts with the global benchmark that calls for around a 4% annual decline to align with net-zero pathways.

Actionable Priorities For Rapid Cuts

To bend the curve quickly, prioritize reductions in the largest and fastest-growing sources: curb methane from crop-related activities, cut nitrous oxide from agriculture, and reduce coal- and oil-based fossil CO2. Rein in smaller but rising sources by tightening F-gas management and limiting land-use emissions. Given extremely high per capita levels, rapid, substantial cuts across these major sectors are essential.

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.

Last 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.

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.
