The OECD stands for the Organisation for Economic Co-operation and Development, which is an intergovernmental economic organization with 37 member states.
Figures added manually from individual tables and calculated by ÌÇÐÄÆÆ½â°æ using hard figures for demand volume provided by the source. Figures due to not sum 100 percent due to rounding.
Road transportation is the greatest oil demanding sector in OECD (Organisation for Economic Co-operation and Development) member states. In 2024, 46 percent of all oil consumed in the OECD was related to motor vehicle usage. By comparison, the petrochemical sector which manufactures plastics, resins, and other petroleum-based products, only made up about 15.5 percent of total demand.
U.S. and China by far largest consumers
The United States and China are the greatest oil consumers worldwide by a wide margin. In 2024, daily oil consumption in these countries amounted to 19 million barrels and 16.6 million barrels, respectively. Daily global crude oil demand, including biofuels, reached 102.21 million barrels in 2024, up from 99.57 million barrels in 2023.
The future road sector
Oil is used in numerous manufacturing processes and still accounts for a large chunk of primary energy supply worldwide. It is largely used to produce transportation fuels such as gasoline, diesel, and kerosene. As such, demand is also shaped by a growth or decline in internal-combustion engine vehicle usage and overall economic performance. During the 2020 pandemic, oil demand within the road sector decreased as lockdowns were enforced across the world. With many countries pushing for a wider adoption of electric vehicles, oil demand in the road sector is likely to be further affected going forward.
