Ukraine's Yearly Greenhouse Gas Emissions in CO₂ Equivalent
✨ Key Insights
Industrialization and Early Emissions
The industrialization of the Donbas region in the 1860s marked the beginning of significant CO₂ emissions in Ukraine. The focus on coal mining and metallurgy led to a steady increase in emissions, as coal became a primary energy source. This trend continued into the early 20th century, with emissions rising as industrial activities expanded.
World War II and Emission Reductions
World War II brought about a temporary reduction in emissions due to the destruction of industrial infrastructure. The war disrupted both industrial and agricultural activities, leading to a decrease in CO₂, CH₄, and N₂O emissions. This period of reduced emissions was short-lived, as post-war reconstruction efforts soon led to a resurgence in industrial activity.
Post-Soviet Decline and Recovery
The collapse of the Soviet Union in 1991 resulted in a significant decline in industrial activity, leading to a marked reduction in CO₂ emissions. This economic disruption caused emissions to drop by tens of millions of megatonnes annually. However, the subsequent recovery and modernization efforts, including the Orange Revolution's policy shifts, gradually stabilized emissions.
Recent Conflicts and Emission Impacts
The annexation of Crimea and the conflict in Eastern Ukraine in 2014, followed by the 2022 Russian invasion, have had profound impacts on Ukraine's emissions. These events led to widespread destruction of infrastructure and a significant reduction in industrial and energy sector emissions. The overall reduction in emissions during these conflicts is estimated to be tens of millions of megatonnes annually, highlighting the severe impact of geopolitical tensions on Ukraine's emission profile.
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)
- Moderate: above 2.5 tonnes
- 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.
