Mechanism of CO2 Emission Reduction by Global Energy Interconnection

The challenge of global warming has become a driving force for a global energy transition. The Global Energy Interconnection (GEI) is a modern energy system aimed at meeting the global power demand in a clean and green manner. With the development of clean replacement, electricity replacement, and grid interconnection strategies, GEI contributes to the global temperature control by dramatically reducing the level of energy-related CO₂ emissions. This study proposes an integrated framework for analyzing the mechanism of CO₂ emission reduction via GEI implementation. The obtained results demonstrate that the total cumulative contribution of GEI to mitigating the effects of CO₂ emissions (estimated by conducting a scenario analysis) corresponds to a total reduction of 3100 Gt CO₂. The contributions of the clean replacement, electricity replacement, and carbon capture and storage GEI components to this process are equal to 55, 42, 5%, respectively. Using GEI, the utilization of clean energy in 2050 will increase by a factor of 4.5 at an annual growth rate of 4.4%, and the electrification rate will be 2.4 times greater than the current one.
