The 2024 edition of the International Atomic Energy Agency’s (IAEA) Climate Change and Nuclear Power report stresses the crucial need to boost investments in nuclear energy to meet global climate goals. Released during the Clean Energy Ministerial in Brazil, the report outlines a detailed roadmap for expanding nuclear power to support countries in achieving net-zero emissions by 2050. With climate change concerns escalating, the report underscores the significance of nuclear power as a clean energy solution and highlights the essential role it plays in diversifying the energy mix for a sustainable future. The report projects that annual energy sector investments of $4.7–$5 trillion are necessary to achieve net zero emissions by mid-century, with a focus on more than doubling the installed capacity of nuclear power. This aligns with the IAEA's high-case scenario, emphasizing the growth potential of nuclear energy. The report also emphasizes the reliability of nuclear power in providing a steady baseload of clean energy and supporting the integration of other renewables into the energy grid. Notably, nuclear power is identified as a critical tool for decarbonizing industrial sectors and enabling advanced energy systems such as hydrogen. To meet the ambitious nuclear power targets, substantial investments are required, with estimates suggesting a global investment increase to $125 billion annually. The report highlights the importance of constructing new nuclear power plants, developing advanced reactor technologies, and deploying small modular reactors (SMRs) to expand nuclear capacity. Moreover, unlocking private sector financing and fostering international cooperation are deemed essential for addressing the financing gap and mobilizing capital for nuclear energy projects. By emphasizing policy reforms and partnerships between governments, financial institutions, and the private sector, the report outlines strategies to attract investments and accelerate the transition to clean energy.
