Russia will allow oil refineries across the country to produce fuel products adhering to the lower-quality Euro-3 standards, according to a government decree published July 2. The decision comes amid a growing fuel shortage in Russia brought on by Ukrainian drone attacks on oil infrastructure.A decree signed by Russian Prime Minister Mikhail Mishustin permits certain refineries to product Euro-3 gasoline through the end of the year. The decision is meant to stabilize the fuel supply in Russia and "prevent destabilization in the domestic market of motor fuel." Euro-3 gasoline represents an older fuel classificiation under European emissions standards. It contains a higher sulfur content than Russia's current standard (Euro-5), leading to increased safety risks and heavier pollution.Under the new temporary regulations, companies may circulate gasoline with a maximum sulfur content of 150 mg per kilogram. These products will not bear the Eurasian Economic Union (EAEU) conformity mark and cannot be exported outside Russia. Earlier, the Russian news outlet Kommersant reported on June 29 that the Kremlin was considering downgrading gasoline and diesel prodution standards to as low as Euro-2, which has been banned in Russia since 2013.
