Although oil demand and carbon emissions have fallen by 15% since 2010, most of this is unrelated to EV sales. Over the period, total oil demand fell by only 34,000 b/d, with gasoline and diesel making up a mere 10% of the decline. Most of the decline came from heating, lighting, and petrochemical demand, which GR estimate collapsed by more than a third. Despite 20% of all vehicles on the road now being electric, Norway's gasoline and diesel demand fell by a mere 4%.
