According to the World Energy Review 2026 report by Eni, based on 2025 data, natural gas consumption in five Central Asian countries reached 119.6 billion cubic meters, representing a 76% increase compared to 2015. Over the same period, the volume of gas exports in the region almost halved, falling from 89.6 billion to 47.4 billion cubic meters.
The total natural gas production in the region in 2025 amounted to about 140.9 billion cubic meters, whereas in 2015 this figure was 153.0 billion cubic meters. Among the producing countries, Turkmenistan contributed the most, producing 72.48 billion cubic meters, Uzbekistan produced 40.16 billion, and Kazakhstan produced 28.21 billion.
Uzbekistan was the largest gas consumer in the region, using 54.32 billion cubic meters, which accounts for 45% of the total regional demand. This is followed by Turkmenistan with consumption of 35.58 billion cubic meters and Kazakhstan with 28.82 billion cubic meters. Per capita, Turkmenistan showed the highest consumption level at 4,671 cubic meters, followed by Uzbekistan (1,466 cubic meters) and Kazakhstan (1,382 cubic meters).
Turkmenistan was also the leading gas exporter in the region, sending 36.89 billion cubic meters abroad, which is approximately 78% of the regional volume. Uzbekistan exported 5.72 billion cubic meters, and Kazakhstan exported 4.77 billion. Meanwhile, Kazakhstan's exports decreased by 28% compared to 20.11 billion cubic meters in 2015.
The total gas import volume in the region reached approximately 26.1 billion cubic meters, of which 19.88 billion cubic meters were directed to Uzbekistan. Kazakhstan imported 5.37 billion cubic meters, Kyrgyzstan imported 0.64 billion, and Tajikistan imported 0.20 billion.
Regional gas reserves are concentrated in Turkmenistan, which holds 13,900 billion cubic meters out of a total of 16,578 billion cubic meters registered in the five countries. Kazakhstan's reserves are estimated at 1,830 billion cubic meters, and Uzbekistan's at 846 billion cubic meters.
In the oil sector, Kazakhstan is the undisputed leader in the region for production. Its output increased by 11.8% in 2025 to 2.098 million barrels per day, covering about 88% of all production in the five countries. Total regional oil production reached approximately 2.385 million barrels per day, compared to 2.030 million in 2015. Turkmenistan produced 200,000 barrels per day, Uzbekistan produced 81,000, and Kyrgyzstan produced 6,000 barrels per day. These figures include oil, including unconventional oil and natural gas.
Kazakhstan exported 1.243 million barrels of oil per day, while Turkmenistan exported 19,000 barrels. Of the total regional oil reserves of 31,041 million barrels, Kazakhstan accounted for 29,799 million barrels.
Oil consumption in the region increased from 602,000 barrels per day in 2015 to 776,000 barrels per day in 2025.
Energy generation from wind and solar has also significantly expanded. Installed solar capacity in the region in 2025 reached approximately 7,359 MW, compared to 4,417 MW the previous year, an increase of 67%. Uzbekistan provided 5,934 MW, and Kazakhstan provided 1,325 MW; the other Central Asian countries contributed a combined 100 MW.
The total installed wind capacity of Kazakhstan and Uzbekistan, two countries for which data is provided in the review, amounted to 3,561 MW, which is higher than approximately 2,021 MW the previous year. Kazakhstan contributed 1,909 MW, and Uzbekistan contributed 1,652 MW. In 2025, Kazakh and Uzbek solar and wind power plants produced 2,075 GWh and 5,401 GWh, respectively. For Uzbekistan, the review only provides data for 2024: 3,965 GWh of solar and 790 GWh of wind energy.
Total CO2 emissions in the five countries amounted to about 473.5 million tons in 2024, compared to 363.8 million tons in 2015. Kazakhstan accounted for 243.0 million tons, or about 51% of the total, followed by Uzbekistan with 121.8 million tons and Turkmenistan with 87.9 million tons. Emissions in Kyrgyzstan were 11.9 million tons, and in Tajikistan were 8.9 million tons. In Kyrgyzstan, they increased by 28.6% year-on-year, and in Tajikistan by 14.2%. Data on emissions for 2025 is not available in the review.
The total population of the five countries in 2025 reached 83.6 million people, compared to 69.6 million in 2015. Uzbekistan has the largest population at 37.1 million, followed by Kazakhstan (20.8 million), Tajikistan (10.8 million), Turkmenistan (7.6 million), and Kyrgyzstan (7.3 million).
The total real GDP of the region in 2015 prices amounted to about 506.7 billion US dollars. Kazakhstan contributed 260.3 billion US dollars, and Uzbekistan contributed 152.4 billion US dollars. Kyrgyzstan demonstrated the fastest economic growth at 11.1%, followed by Tajikistan (8.4%), Uzbekistan (7.7%), Kazakhstan (6.5%), and Turkmenistan (6.3%).
