Oil and gas in the global economy through 2050

From the Canadian Energy Centre

The world will continue to rely on oil and gas for decades to come, according to the International Energy Agency

Recent global conflicts, which have been partly responsible for a global spike in energy prices, have cast their shadow on energy markets around the world. Added to this uncertainty is the ongoing debate among policymakers and public institutions in various jurisdictions about the role of traditional forms of energy in the global economy.

One widely quoted study influencing the debate is the International Energy Agency’s (IEA) World Energy Outlook, the most recent edition of which, World Energy Outlook 2023 (or WEO 2023), was released recently (IEA 2023).

In this CEC Fact Sheet, we examine projections for oil and natural gas production, demand, and investment drawn from the World Energy Outlook 2023 Extended Dataset, using the IEA’s modelled scenario STEPS, or the Stated Policies Scenario. The Extended Dataset provides more detailed data at the global, regional, and country level than that found in the main report.

The IEA’s World Energy Outlook and the various scenarios

Every year the IEA releases its annual energy outlook. The report looks at recent energy supply and demand, and projects the investment outlook for oil and gas over the next three decades. The World Energy Outlook makes use of a scenario approach to examine future energy trends. WEO 2023 models three scenarios: the Net Zero Emissions by 2050 Scenario (NZE), the Announced Pledges Scenario (APS), and the Stated Policies Scenario (STEPS).

STEPS appears to be the most plausible scenario because it is based on the world’s current trajectory, rather than the other scenarios set out in the WEO 2023, including the APS and the NZE. According to the IEA:

The Stated Policies Scenario is based on current policy settings and also considers the implications of industrial policies that support clean energy supply chains as well as measures related to energy and climate. (2023, p. 79; emphasis by author)

and

STEPS looks in detail at what [governments] are actually doing to reach their targets and objectives across the energy economy. Outcomes in the STEPS reflect a detailed sector-by-sector review of the policies and measures that are actually in place or that have been announced; aspirational energy or climate targets are not automatically assumed to be met. (2023, p. 92)

Key results

The key results of STEPS, drawn from the IEA’s Extended Dataset, indicate that the oil and gas industry is not going into decline over the next decade—neither worldwide generally, nor in Canada specifically. In fact, the demand for oil and gas in emerging and developing economies under STEPS will remain robust through 2050.

Oil and natural gas production projections under STEPS

World oil production is projected to increase from 94.8 million barrels per day (mb/d) in 2022 to 97.2 mb/d in 2035, before falling slightly to 94.5 mb/d in 2050 (see Figure 1).
