With the formulation of the “double carbon” target, the transportation industry has become an important part of the low carbon field, and the “decarbonization” target of the automobile industry has become imperative. This paper focuses on the automobile carbon neutrality, discusses the areas of automobile carbon footprint, and analyzes the path of automobile carbon neutrality. With the technical support and policy encouragement of the government, automobile enterprises in various countries promote the automobile to achieve the carbon peak and carbon neutral target at present. This article explains the three paths of automobile lightweighting and green internal combustion engine materials for new energy vehicles to explain the technological updates and industry development of automobile energy conservation and emission reduction and low-carbon development, providing a path reference for the goal of carbon neutrality. From those three paths, the development of the automobile industry needs higher and more perfect requirements for low-carbon technologies and low-carbon solutions in future. However, each carbon neutral path has its own barriers and needs to develop a more complete and closed-loop management application system for the path. The paper analyzes that each path brings new opportunities and challenges to the development of automobile industry to achieve the goal of carbon peak and carbon neutrality. Meanwhile, it has injected new impetus into the development of the automobile industry.
