OPEC’s 2050 Outlook: Petrochemicals Driving Long-Term Oil Demand Amid Energy Transition
July 14, 2025 – The Organization of Petroleum Exporting Countries (OPEC) has released its latest World Oil Outlook 2025, presenting a nuanced picture of oil demand through the middle of the century. Contrary to widespread assumptions that energy transition efforts will drastically curtail oil consumption, OPEC’s forecast highlights petrochemicals as a critical growth engine sustaining long-term oil demand. The report projects petrochemical oil demand will surge by nearly 5 million barrels per day (mbd), from 15.5 mbd in 2024 to 20.2 mbd by 2050, underpinning oil’s enduring role in the global energy mix.
Petrochemicals: The Long-Term Growth Driver
Petrochemicals are forecasted to account for 16% of total oil demand by 2050, up from 14% in 2024. This growth is heavily concentrated in the Middle East and China, which together contribute 90% of the incremental demand. Expanding industrial capacity, rising GDP, and demographic momentum in these regions are fueling this increase.
“Petrochemicals demand for oil will predominantly be as a feedstock, as more competitively priced fuels such as natural gas remain viable alternatives,” the report notes. While natural gas and biomass will gain increased share as feedstocks, naphtha and liquefied petroleum gas (LPG) remain indispensable for many downstream petrochemical processes due to their suitability for producing high-value materials.
Regional and Sectoral Demand Dynamics
The report delineates clear regional contrasts:
-
OECD countries: Petrochemical demand is expected to peak around 2035 before entering a slow decline, stabilizing at about 7.7 mbd—close to current levels. This trend mirrors tight oil production patterns in the U.S., where LPG and ethane play dominant roles as feedstocks.
-
Non-OECD countries: Demand growth is robust, propelled by population growth and expanding middle-class consumption. Oil demand from petrochemicals in these countries is projected to rise from nearly 8 mbd in 2024 to 12.5 mbd in 2050, reflecting an incremental increase of 4.6 mbd. Here, ethane/LPG demand is set to increase by more than 4 mbd, with naphtha adding 2.4 mbd to incremental demand.
China remains the largest single-country driver, with oil demand peaking at 17.7 million barrels of oil equivalent (boe) per day in 2035, largely fueled by petrochemical expansion and heavy transportation sectors, before moderating slightly due to increased adoption of electric vehicles (EVs).
Transport Sector: The Backbone of Oil Demand
Transport continues to underpin the majority of oil consumption. In 2024, the sector accounted for 57% of global oil demand, a share expected to be maintained through 2050. The aviation segment is particularly notable as the only transport sub-sector forecasted to grow steadily over the next 25 years, expanding demand by approximately 1 mbd despite environmental pressures and technological shifts.
This steady aviation growth contrasts with other transport subsectors where electrification and efficiency gains may temper oil consumption.
Environmental and Regulatory Challenges
Despite these robust demand drivers, OPEC’s outlook underscores the influence of environmental regulations and sustainability initiatives that could temper growth:
- Carbon footprint reduction commitments
- Increasing recycling and circularity of petrochemical products
- Restrictions on single-use plastics
- Growing penetration of bioplastics
These policies, coupled with market uncertainties such as US trade tariffs, create a complex environment for petrochemical growth, requiring active industry adaptation.
Oil’s Enduring Share in the Global Energy Mix
OPEC projects global oil consumption reaching 123 mbd by 2050, maintaining oil’s share as the largest component of the energy mix at just under 30%. Despite the rise of renewables—which are forecast to increase their share by 10 percentage points to 13.5%—and gains in natural gas and biomass, oil and gas combined are expected to account for over half of global energy demand between now and 2050.
This persistence reflects the essential roles oil plays not only in transportation but also in the petrochemical sector, where its derivatives are foundational to modern materials and technologies, including components used in renewable energy infrastructure.
Strategic Considerations for Investors
For market participants and investors, OPEC’s outlook suggests several key themes:
-
Thematic Exposure to Petrochemicals: Investing in companies linked to petrochemical production offers alignment with industrialization and demographic expansion trends, particularly in Asia and the Middle East.
-
Regulatory Risk Management: Environmental policies and sustainability mandates may pressure traditional petrochemical feedstocks, mandating vigilance and adaptive strategies.
-
Energy Sector Diversification: A balanced portfolio incorporating renewables, natural gas, and petrochemicals can mitigate risks amid an evolving energy landscape.
Conclusion
OPEC’s 2050 World Oil Outlook presents a complex but clear narrative: petrochemicals will play a pivotal role in sustaining oil demand through the energy transition era. Driven by demographic and industrial growth in key regions, the sector’s rising feedstock needs offset declines elsewhere, ensuring oil’s continued relevance in the global energy system for decades to come.
Investors and policymakers alike should take note of the intertwined forces shaping this trajectory—economic growth, technological evolution, and environmental imperatives—recognizing that the energy transition will be neither swift nor linear, but marked by persistent reliance on oil’s versatile derivatives.
