Opinion: A Railway to the Future – Uzbekistan’s Bold Path to Connectivity and Carbon Cuts
I still remember the thrill of boarding the sleek high-speed train from Tashkent to Bukhara. What could have been an ordinary journey turned into something unforgettable - the kind of experience that stays alive in the memory long after the trip ends. The speed, the comfort, and above all, the hospitality of Uzbekistan Railways revealed more than just modern engineering; it was a glimpse into the vision of a country determined to connect its people and its future to the wider world. The resonance of this project is deep. The Silk Road was once the artery of global exchange, moving not just goods but ideas, cultures, and entire civilizations between East and West. From Xi’an to Samarkand, Bukhara, and Tashkent, caravans carried silk, porcelain, and paper eastward, while wool, stones, fruits, and glassware travelled west. The CKU Railway is not simply another infrastructure project; it is the revival of this legacy, adapted for the 21st century. By shortening transport routes by nearly 900 kilometers and halving transit times, it promises to transform Uzbekistan’s geographic disadvantage into a strategic strength. For a landlocked country, this is more than steel on tracks - it is a lifeline to global markets. That is where railways carry an underappreciated advantage. Beyond the economics, rail is also a climate solution. The International Energy Agency (IEA) has found that rail freight is three to four times more energy-efficient than trucks. Trains use 65–80% less fuel per kilogram of cargo. The European Environment Agency calculates that a ton of freight moved by train emits 14–20 grams of CO₂ per kilometer, while the same tonnage on trucks produces 60–120 grams. That is a four- to fivefold difference. If the 20th century belonged to highways, the 21st must belong to railways. To grasp what this means for Central Asia, consider the region’s emissions profile. According to the EDGAR 2023 dataset, annual greenhouse gas emissions (excluding LULUCF, 2022) stand at roughly 320 MtCO₂e for Kazakhstan, 214 MtCO₂e for Uzbekistan, 99 MtCO₂e for Turkmenistan, 22 MtCO₂e for Kyrgyzstan, and 21 MtCO₂e for Tajikistan. Transport is responsible for around a tenth of that, and road freight dominates. The opportunity for reductions through a modal shift is therefore enormous. Take Uzbekistan as a case in point. The country moves about 90 billion ton-km of freight annually, within a regional total of some 350 billion. At present, 70% of this moves by road and 30% by rail. Imagine that by 2035, half of current road freight shifts to electrified rail - around 32 billion ton-km. On trucks, that freight would generate 2.9 MtCO₂e per year. On electrified trains, it would produce only 0.54 MtCO₂e. The savings: 2.4 MtCO₂e annually, or more than 1% of Uzbekistan’s entire national emissions. For a single infrastructure project, that is an extraordinary return in climate terms. The regional potential is just as striking. If similar shifts occurred across Central Asia, annual savings would reach 7–9 MtCO₂e by 2035 - the equivalent of removing two million cars from the road....
