Abstract This Special Issue of the International Journal of Chemical Reactor Engineering (IJCRE) presents selected manuscripts from the International Energy Conference 2023 (IEC 2023), which took place in Zacatecas, Mexico, from September 18 to 22, 2023. As a biennial event, the IEC fosters research and discussions on global energy challenges. The 2023 edition of the conference focused on the role of sustainable processes in addressing energy and climate change. Key topics included energy efficiency, life-cycle assessments, sustainability strategies, public policies, and energy awareness. Beyond these themes, the IEC 2023 provided a platform for knowledge exchange, critical discussions, and reflections on the influence of both fossil fuels and renewable energy sources on the global energy landscape.
