Explanation

The United Kingdom has set a target to ban the sale of new petrol and diesel cars by 2035 (though this is often cited in discussions about 2030 targets). China has ambitious goals but the specific 2030 ban for all listed options is most closely associated with UK policy discussion. The United States does not have a single federal mandate matching this exact date and scope. Russia's current stated policies do not include such a comprehensive national ban by 2030.
