<p>Fuel quality improvements have broadly continued to stagnate across Russia and the CIS region. The main reason is the situation in Russia, which plays a central role in regional refining and fuel exports. Western sanctions imposed in response to Russia&rsquo;s invasion of Ukraine have made it difficult for the country to align its fuel standards with those of the EU. This has slowed progress on sulfur reduction, the wider availability of higher-octane gasoline, and the renewal of the vehicle fleet.</p>

Slow Transition Toward Cleaner Fuels in CIS as Russia Maintains Status Quo

<h2>Key Points</h2>
<ul>
<li>Russia maintains 10 ppm sulfur limits for fuels, but enforcement has weakened due to legal changes that limit sampling and monitoring scope;</li>
<li>The Russian government&rsquo;s temporary waiver allowing production of Euro 2-4 vehicles was extended beyond the original Feb. 1, 2024, deadline but raised to Euro 3;</li>
<li>Armenia and Belarus continue importing mainly Russian fuels, with no significant changes to domestic specifications or monitoring systems;</li>
<li>Refinery upgrades were completed in Azerbaijan, allowing it to transition to 10 ppm sulfur limits for fuels;</li>
<li>Kazakhstan has seen some increase in RON 95 gasoline share, but still lacks robust enforcement of quality rules;</li>
<li>Kyrgyzstan was granted an extension until Jan. 1, 2027, to fully implement EEU fuel quality rules, including the 50 ppm sulfur limit;</li>
<li>Tajikistan and Turkmenistan have made no recent legislative progress and continue to allow high-sulfur fuels, including 2,000 ppm for diesel in the latter;</li>
<li>Uzbekistan has implemented 50 ppm sulfur limits for imported fuels only, while mandating the transition for domestic production standards to take place by 2028;</li>
<li>RON 92 gasoline remains the dominant grade across the region, though RON 95 is gradually gaining ground in Kazakhstan and Russia;</li>
<li>Only Russia has implemented Stage III emission requirements for off-road vehicles, with compliance deadlines for the rest of the EEU now set for 2025-2027 according to vehicle type;</li>
<li>Fuel quality monitoring remains weak or poorly enforced in Russia, Azerbaijan, Kazakhstan, Kyrgyzstan, and Uzbekistan;</li>
<li>Illegal fuel imports and black-market distribution persist in parts of Central Asia, especially in Kyrgyzstan, Tajikistan, and Uzbekistan.</li>
