The Chinese government has announced the goal of carbon peak and carbon neutrality, demonstrating China's responsibility as a major country to actively respond to climate change and promote sustainable development of the world. In recent years, state-owned grain storage enterprises have vigorously promoted energy saving, carbon reduction, and efficient development in upgrading grain storage facilities and equipment, innovating grain storage technology and, strengthening standardized storage management. Combined with the current situation of the development of state-owned grain storage enterprises, the concept of "carbon neutral grain" was proposed firstly in the paper. Under the goal of carbon neutrality, state-owned grain storage enterprises should do a good job of “subtraction” of low carbon operation as well as actively utilize “addition” of green energy such as photovoltaic power generation, taking the lead to realize their own low carbon development and lead the industry as an example.
