Latvia's Yearly Greenhouse Gas Emissions in CO₂ Equivalent
Key Insights
2024 Emissions Profile
In 2024, CO2 was Latvia's largest source at around 9.4 megatonnes CO2, or 66% of the national total, falling by about 0.12 megatonnes CO2 per year over the ten years to 2024. Methane was about 2.2 megatonnes CO2e (16%) and declining by roughly 0.02 megatonnes CO2e annually; nitrous oxide was also around 2.2 megatonnes CO2e (15%) and broadly stable. F-gases contributed about 0.34 megatonnes CO2e, or 2%, and edged upward.
Historic Carbon Dioxide (CO2) Emissions
CO2 emissions began at around 7 megatonnes CO2 in the 1850s and declined overall to roughly 5 megatonnes by the late 1940s, despite fluctuations. They then rose sharply, peaking at about 27 megatonnes CO2 in 1985, before falling steeply to around 4 megatonnes by 1997. Emissions subsequently varied, ending at around 9.4 megatonnes CO2 in 2024.
Historic Methane (CH4) Emissions
Methane emissions started at roughly 2.1 megatonnes CO2e in 1851 and rose gradually to around 4.3 megatonnes by the late 1970s. They peaked at approximately 4.8 megatonnes CO2e in 1992, then declined overall, reaching about 2.2 megatonnes CO2e in 2024. Methane's warming contribution since 1851 was around one-third smaller than its emissions alone suggest, because methane's short atmospheric lifetime dampens the warming impact when CH4 emissions are falling.
Historic Nitrous Oxide (N2O) Emissions
Nitrous oxide emissions began at around 0.2 megatonnes CO2e in 1851 and increased steadily through the mid-20th century. Growth accelerated after the 1940s, reaching a peak of roughly 2.7 megatonnes CO2e in 1987. Emissions fell during the early 1990s, then recovered gradually, ending at around 2.2 megatonnes CO2e in 2024.
Historic Fluorinated Gases (F-gases) Emissions
F-gas emissions were effectively zero until the early 1990s. They then increased gradually from near zero in 1993, reaching their highest level of around 0.34 megatonnes CO2e in 2024. Despite this rise, F-gases remained a small part of Latvia's emissions throughout their recorded history.
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.
- Carbon Dioxide (CO2)
- 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.

Crabon Dioxide (CO2)
CO2 includes emissions from fossil fuels and industry (FFI), and from land-use, land-use-change, and forestry (LULUCF).
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.

National CO2 emissions data through 2024 is from the Global Carbon Project and covers fossil sources and land-use change. Emissions data through 2024 for CH4, N2O and F-gases comes from the PRIMAP-hist dataset, which combines several published sources into historical emissions time series.
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.
