Climate change is a major challenge facing all nations， posing a threat to the very survival and development of humankind. The global average temperatures has increased nearly 1.2℃compared to pre-industrial levels， approaching the temperature rise control goals under the Paris Agreement at an alarming pace， bringing humanity to a make-or-break moment. UN Secretary-General Antonio Guterres has called on all nations worldwide to declare a state of "climate emergency"， and to make concerted， concrete efforts to advance carbon neutrality and address climate change. Carbon neutrality is fundamental to the path towards resolution of the climate and environment crisis. An important enabler of sustainable development， it will act as a strong driver of green transformation in the economy and society and of the building a community with a shared future for mankind.
　　Achieving carbon neutrality will be an extremely complex and arduous task. While over 120 nations have announced carbon neutrality goals， laying a solid foundation for achieving carbon neutrality by the middle of this century. and for implementing the targets of the United Nations Framework Convention on C/imate Change （UNFCCC） and the Paris Agreement， to date nations' progress on mitigation has fallen short of what global carbon neutrality is meant to achieve. A key problem is the lack of feasible systematic solutions. To that end， related organizations and institutions have pursued in-depth research and extensive international cooperation to promote the formulation of climate policies and to mobilize mitigation measures worldwide.
　　Excessive use of fossil fuels constitutes the root cause of the climate crisis. Thus， in order to secure carbon neutrality， energy， the decisive factor driving climate change， must be addressed， and major efforts made to expedite the energy and electric power revolution and implement the "Two Replacements"， namely， clean replacement in energy production and electricity replacement in energy consumption. Global Energy Interconnection （GEI） offers an innovative energy system characterized by clean energy production， extensive distribution of clean energy， and electrification of energy consumption， which will constitute an important platform for the development， transmission and use of clean energy on a global scale. It provides a technically advanced， cost-effective， systematic win-win solution permitting the achievement of the targets of the Paris Agreement， capable of facilitating the global efforts to achieve carbon neutrality by the middle of this century， resolving the climate and environmental crisis， promoting high-quality economic development， and advancing the sustainabledevelopment of humankind.
