Georgia's Yearly Greenhouse Gas Emissions in CO₂ Equivalent
Key Insights
Historic Emissions At A Glance
Since 1850, Georgia's human-caused emissions have been led by CO2 from fossil fuels, responsible for around 60% of the country's warming impact and adding up to roughly 700 megatonnes over time. Methane contributes roughly 27% (about 400 megatonnes cumulatively), nitrous oxide about 17% (around 200 megatonnes), while land use has acted as a small net absorber, offsetting a few percent of total warming. Fluorinated gases remain a very minor source, emerging only since the early 1990s and staying under 10 megatonnes in total.
Fossil CO2: Rise And Rebound
Fossil CO2 rose slowly until the mid‑20th century, surged from the post‑war era to the early 1990s, and peaked at roughly 15 megatonnes. An abrupt collapse followed in the early 1990s, then emissions climbed steadily from the late 1990s to the low teens by 2024. Oil and gas each account for about two‑fifths of historic fossil CO2: oil grew to the early 1980s, fell in the 1990s, then trended upward since the turn of the century; gas expanded rapidly through the early 1980s and has varied since. Coal has declined long‑term, with only a modest uptick after 2003.
Methane And Nitrous Oxide Trends
Methane rose through the late 1970s and has gradually eased since the early 1980s, from roughly 4 to just over 3 megatonnes per year; as emissions stabilized and fell, the warming impact from methane declined sharply. Livestock and waste dominate these emissions. Nitrous oxide jumped mid‑century to around 3 megatonnes by 1980, then decreased and has stabilized just under 2 megatonnes since the late 1990s, with agriculture the largest source and industrial contributions lower than their peak.
Current Trajectory And Priorities
Today, the main drivers-CO2 from oil and gas-are elevated and have trended upward, while coal remains below past highs. Methane and nitrous oxide are broadly stable to gently declining, and land use provides a modest sink. Reversing growth in fossil fuel emissions is the central task, while sustaining declines in methane and nitrous oxide and preserving the land sink can consolidate progress.
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.

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.
