Renewable energy cuts emissions in GCC, but oil dependence keeps climate pressure high

A new analysis has found that renewable energy is beginning to reduce carbon emissions across Gulf Cooperation Council (GCC) countries, but the region’s deep dependence on hydrocarbon rents continues to drive environmental pressure. The study shows that clean energy expansion can weaken the link between natural resource dependence and emissions, but not enough to offset the carbon burden of oil- and gas-centered growth models.

The study, titled “Renewable Energy, Natural Resource Rents, and Environmental Quality in GCC Countries,” was published in Resources. Using panel data from Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and the United Arab Emirates from 1990 to 2024, the research examines how natural resource rents and renewable energy affect CO2 emissions in some of the world’s most hydrocarbon-dependent economies.

Hydrocarbon rents remain a major driver of emissions

Oil and gas revenues have helped finance growth, fiscal stability, infrastructure expansion and industrial development across the Gulf. But that model has also created economies built around energy-intensive production, high per capita emissions and continued dependence on fossil fuels.

The analysis confirms that natural resource rents remain positively associated with environmental degradation in the region. The estimated relationship is economically significant: a 10% rise in resource rents is associated with about a 2.2% increase in CO2 emissions. This reflects the continued role of hydrocarbon extraction, petrochemicals, electricity generation, desalination, transport and heavy industry in the region’s emissions profile.

The findings support the view that resource-rich economies can become locked into carbon-intensive development paths. When oil and gas revenues dominate public finance, exports and industrial policy, governments face strong incentives to maintain hydrocarbon production and domestic fossil-fuel use. Even when renewable energy projects expand, they may do so within an economy still powered largely by oil and gas.

Energy consumption emerges as the strongest emissions factor in the study. A 10% rise in energy consumption is associated with nearly a 4.7% increase in emissions, showing that fossil-fuel-based energy demand remains central to the GCC’s environmental challenge. Economic growth also has a positive association with emissions, suggesting that expansion in the region still works largely through scale effects rather than cleaner structural transformation.

Trade openness and urbanization also contribute positively to emissions, though at more moderate levels. This is consistent with the region’s highly urbanized, trade-linked economic structure, where large cities, industrial zones, logistics systems and export-oriented energy sectors continue to rely heavily on conventional energy.

Country-level findings show that the emissions effect of resource rents is not uniform across the GCC. The positive association is strongest in Qatar and Saudi Arabia, reflecting their high hydrocarbon dependence and energy-intensive economic structures. Bahrain shows a lower, though still positive, relationship. These differences suggest that national energy systems, diversification strategies and industrial profiles shape how resource rents translate into environmental pressure.

Renewables help, but their impact remains modest

Renewable energy is negatively linked with CO2 emissions across GCC countries, supporting the case for clean energy expansion. The study finds that a 10% increase in renewable energy is associated with roughly a 1.5% reduction in emissions. This confirms that renewable energy can improve environmental quality, even in economies where fossil fuels remain dominant.

The finding aligns with recent GCC policy shifts. Saudi Arabia, the UAE, Oman and other Gulf states have launched renewable energy programs as part of broader economic diversification and climate strategies. Solar power, wind projects, green hydrogen plans and clean industrial initiatives are increasingly framed as central to the region’s transition beyond oil.

However, the study makes clear that the current contribution of renewable energy remains limited compared with the scale of fossil-fuel dependence. Renewable energy still accounts for a relatively small share of total final energy use in the region. As a result, its emissions-reducing effect is real but moderate.

Renewable energy weakens the positive relationship between natural resource rents and CO2 emissions. In simple terms, cleaner energy helps reduce the environmental damage linked to hydrocarbon dependence. But it does not reverse that relationship. Even at higher renewable energy levels, resource rents remain positively associated with emissions.

Renewable energy is currently acting as a partial mitigating force, not a full substitute for fossil fuels. The study finds that the interaction effect is negative but only partly robust across different model checks. It suggests that renewable energy expansion in the GCC is not yet deep enough to structurally change the region’s emissions trajectory.

The country-level results again show variation. Renewable energy has the strongest negative association with emissions in Oman and the UAE, where clean energy deployment and diversification efforts have advanced more visibly. The moderating role of renewable energy is also stronger in Oman, the UAE and Bahrain. This points to the importance of national policy design and implementation pace.

To sum up, renewable energy can help reduce emissions, but only if it increasingly substitutes for fossil fuels. If renewable power is added while oil and gas consumption, production and energy-intensive industries continue to expand, environmental gains will remain limited.

GCC transition needs structural reform beyond clean energy capacity

GCC countries cannot rely on renewable energy capacity alone to deliver deep decarbonization. Clean power must be tied to reforms that change how energy is priced, consumed and integrated into national economies.

The author identifies fossil-fuel subsidy reform as a priority. Historically low domestic energy prices have encouraged high consumption and slowed cleaner substitution. Gradual reform of energy pricing could reduce waste, improve efficiency and make renewable energy more competitive in power generation, transport and industry.

Grid modernization is another urgent area. Large-scale solar and wind integration requires stronger transmission systems, regional interconnection, storage capacity and smart-grid infrastructure. Without these investments, renewable energy may struggle to displace fossil fuels at scale, even where solar and wind resources are abundant.

The study also points to the need for renewable electricity mandates in high-emission sectors. Desalination, petrochemicals and heavy industry are central to GCC economies, but they remain energy-intensive. Requiring these sectors to procure or generate cleaner electricity could strengthen the substitution effect of renewables and reduce the emissions intensity of production.

Green hydrogen and clean industrial clusters are also highlighted as important pathways, especially in Saudi Arabia, the UAE and Oman. These initiatives could help link renewable energy to industrial diversification, export opportunities and lower-carbon production. But their environmental value will depend on whether they reduce fossil-fuel dependence rather than simply create additional energy markets.

The study also calls for broader economic diversification. As long as fiscal revenue, exports and production systems remain centered on hydrocarbons, renewable energy will face structural limits. Reducing the environmental impact of resource rents requires shifting growth models toward less carbon-intensive sectors and strengthening institutional support for environmental policy.

The paper acknowledges limits in its analysis. It uses aggregate renewable energy data and does not separate solar, wind or other renewable sources. It does not directly model institutional factors such as climate regulation, governance quality or fossil-fuel subsidy reforms. The study also interprets the results as long-run associations, not strict causal effects, because macro-panel data cannot fully rule out endogeneity.
