Petroleum storage depots throughout Ukraine were destroyed by missile attacks. During the first 18 months of the war the fires occurred at more than 30 major oil depots in many regions.
The largest oil re neries of Ukraine were also destroyed: Kremenchutsk (capacity of 18.6 million tons of oil per year), Lysychansk (16 million tons), Kherson, and Odesa.
On this basis, the total GHG emissions caused by fires at all these facilities during 18 months of the war was calculated as 5.43 MtCO2-eq. (+/– 20.3 %), including 5.41 Mt of CO2, 210 t of CH4, and 42.1 t of N2O.
In 2014, three Ukrainian provinces/oblasts were occupied by the Russian Federation: 1.) Autonomous Republic of Crimea and Sevastopol city (area 26,861 km2); 2.) Donetsk oblast (8062 km2); and 3.) Lugansk oblast (8377 km2). The total area of these territories not controlled by Ukraine after 2014 was more than 43,300 km2, which is greater than the area of the Netherlands (41,500 km2). Moreover, the latter two regions are highly industrialized. Large power plants, metallurgical plants, coke plants, hard coal mines, etc. are located in these regions.

https://t.center/EuropaFacts/25Coke plants located in the eastern part of Ukraine practically did not work starting from February 24, 2022. Based on the emissions of this sector in 2021 (NIRU, 2023), we calculated the reduction of emissions in 2022 to be 3.25 MtCO2-eq., and for the first 18 months of the war to be 5.71 MtCO2-eq.
The total emissions of CO2 from the use of fossil fuels amounted to 159.7 Mt.
We do not have complete input data on what the restoration of Ukraine will include, but even with simplified estimates based on the area of destroyed buildings (approx. 0.3t CO2 eq./m2) and the length of destroyed roads (approx. 65 t CO2 eq./km of road) we get to emissions in the order of 600 million tons of CO2 eq.
