Non-secondary GHG reduction technologies: dispose of non-secondary GHG at source, process and end, reduce the burden of carbon sinks and negative emission technologies, and recycle non-secondary GHG at the same time. According to the control method, it can be divided into source reduction, process control, terminal disposal and comprehensive utilization technology.
CCUS technology: CCUS technology captures the carbon dioxide produced in the production process and stores it in geological structures to reduce emissions to the atmosphere. Part of it can also be used as "green carbon" to become raw material supply for relevant production processes in the future. According to the process flow, it may include capture technology, compression and transportation technology, geological utilization and storage technology.
Negative carbon technology: mainly aimed at the carbon emissions that are difficult to reduce, divided into carbon sink and other negative carbon technology. Carbon sink technology absorbs carbon dioxide from the atmosphere through afforestation, vegetation restoration and other measures. Other negative carbon technologies remove carbon dioxide from the atmosphere through direct air capture, enhanced mineral weathering, and artificial photosynthesis.
Integrated coupling and optimization technology: By strengthening the integrated optimization among technologies, the combination of various technologies in specific scenarios can achieve the optimal carbon reduction effect, and strengthen the coordination of carbon neutrality goals with other socio-economic development goals and sustainable development goals. Including energy interconnection, industrial collaboration, energy conservation, pollution reduction and carbon reduction, management support technology.
