Carbon neutrality has become the most urgent and critical mission in the world. Currently, it has been proposed as a target in over 120 countries and regions. The ICT industry is the main force in global economic development. With the large-scale commercial use of 5G, carbon emissions have become a serious challenge to the development of the industry. Building zero carbon networks and achieving carbon neutrality are the strategic objectives of major operators and Internet giants. The ICT industry should not only achieve its own carbon neutrality, but should also empower thousands of industries and promote the carbon neutrality process of them.
