A new Scientific Reports study revisits the long-running relationship between energy use, economic growth and environmental pressure in Saudi Arabia. Using a time-series approach covering 1970 to 2023, the research examines whether urbanisation and human capital change how energy use connects to emissions.
The central finding is that both urbanisation and human capital matter, but not in the way some analysts might expect. Rather than acting as moderating forces that alter the strength or direction of the energy-emissions relationship, they appear to influence the broader nexus through direct channels of their own.
That distinction is important for understanding Saudi Arabia’s development path. It suggests that changes in cities, population skills and education should not be viewed only as factors that reshape the impact of energy consumption. Instead, they need to be treated as separate drivers within the wider interaction between growth, energy demand and emissions.
The study adds a country-specific perspective to debates over sustainable development in major energy-producing economies. By focusing on Saudi Arabia across more than five decades, it highlights how urbanisation and human capital can play a meaningful role in emissions outcomes even without serving as moderating variables in the energy-growth-environment framework.
