Ukraine's Sources of CO2 Emissions

Key Insights

Long Industrial Rise, Sharp Turn

Ukraine's emissions story is dominated by coal, which accounts for a little over two-fifths of national CO2, with land-use change close to one-fifth and oil and gas each around one-sixth. After slow beginnings, emissions accelerated during the post‑war era. From the mid‑1960s to the late 1980s, fossil CO2 surged, driven by coal, reaching a peak well over 300 megatonnes before turning sharply downward in the early 1990s.

Coal, Oil And Gas Paths

Coal fell rapidly through the 1990s-roughly halving-then declined more gradually, with another steep drop in recent years to well under 100 megatonnes. Gas climbed quickly through the 1970s and 1980s to just over 200 megatonnes, but has contracted steadily since the end of the 1980s to around 50 today. Oil rose to just over 200 megatonnes in the 1980s, then fell quickly and has hovered around 30-40 megatonnes since the late 1990s. Other fossil processes remain small and have trended down since the mid‑1970s.

Land Use Moving Toward Balance

Land-use emissions were high in the early 20th century-around 150 megatonnes-then eased through the post‑war decades, approaching near balance by the late 1990s, even briefly turning into a small net sink. Since then, modest emissions have returned in the single to low double digits, far below fossil sources.

Outlook And Near-Term Priorities

The current trajectory shows falling coal and gas emissions and relatively low, stable oil. Locking in these declines requires accelerating clean electricity, efficiency, and electrification across industry and buildings. Land stewardship that prevents renewed land-use emissions can complement fossil reductions and keep overall national emissions on a downward path.

Background

The chart shows a national breakdown by source of the yearly CO2 emissions from human activities and processes expressed in megatonnes. It is critical to know and track the sources of national CO2 emissions in order to understand their individual impacts on climate change.

The sources of human CO2 emissions are

  • CO2 From Fossil Fuels and Industry: coal, oil, gas combustion, other fossil processes
  • CO2 From Land-Use, Land-Use Change, and Forestry

Coal, oil and gas combustion

Fossil fuel CO2 emissions from the combustion of coal, oil and gas are emitted by processes in electricity generation, transport, industry, and the building sector. All processes can be linked to human activities. Examples include driving cars with combustion engines burning diesel or gas, or electric cars charged by electricity from a power plant that burns coal.

Other fossil processes

Fossil CO2 emissions from other processes include sources like cement manufacturing and production of chemicals and fertilizers. Cement also has an absorption factor highlighted in the absorption breakdown chart.

Land-use change

Human civilization emits CO2 by changing and managing its land. Those emissions come, for example, from deforestation, logging, forest degradation, harvest activities and shifting agriculture cultivation. Land-use change also absorbs considerable amounts of CO2, which is shown in the absorption breakdown chart. Land-use change emits more than it absorbs, so the net effect is still emissions, but less than for coal, oil and gas.

Units and Measures

CO2 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 is 2023. CO2 emissions data is from the Global Carbon Project. It contains national CO2 emissions from fossil sources and land-use change.

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.
