World Energy Transitions Outlook 2023: 1.5°C Pathway Summary

Introduction

The International Renewable Energy Agency (IRENA) report emphasizes the urgency of limiting global temperature rise to 1.5°C by driving a rapid energy transition. Current efforts are insufficient to meet this goal, highlighting the need for bold actions to decarbonize the energy system while supporting economic resilience, equity, and human welfare.

Key Messages

Emery Challenges: Current pledges and policies fall short of the 1.5°C target, resulting in a projected emissions gap of 16 gigatonnes by 2050. Annual investments must quadruple to USD 1.3 trillion to reach cumulative USD 150 trillion by 2050, averaging USD 5 trillion annually.
Renewable Deployment: Renewables capacity additions are insufficient; existing targets will only provide 5.4 terawatts by 2030, less than half of the 11.2 TW needed for 1.5°C. Concentration in key regions like China, EU, and US exacerbates global disparities.
Structural Barriers: Progress is hampered by fossil fuel dependency, inefficient systems, and slow policy implementation. Delays increase investment needs and climate risks.

Main Findings

Investment data shows renewables reached USD 0.5 trillion in 2022 but lacks scale in developing regions like Africa, where investment per capita is deeply unequal.
End-use electrification, energy efficiency, and hydrogen are critical for reducing emissions, but policy gaps and funding shortfalls limit their rollout.
The transition must address societal justice, ensuring equitable access and benefits to avoid widening energy poverty and economic divides.

Recommendations

Short-Term Measures: Ambitious renewable and energy efficiency targets; institutional reforms; streamlined permitting; public finance for infrastructure.
Priority Pillars: Physical infrastructure upgrades, policy enablers, and a skilled workforce training program are essential for simultaneous action.
International Cooperation: Channel funds toward Global South, reform financial institutions, and enhance collaboration to avoid climate-related risks and foster inclusive growth.

Conclusion

Immediate, transformative actions are required to catalyze the energy transition, embedding equity and resilience in policies to achieve the 1.5°C goal and sustainable development.
