Rapid and far‐reaching transitions are required to combat climate change and its impacts. Carbon capture and storage within mineral deposits is a promising solution to remove CO2 from the atmosphere. In‐situ geological storage and ex‐situ mineral sequestration are practically sufficient for sequestering all the anthropogenic CO2. Recent research reports that more than 95% of injected CO2 was mineralized into carbonates in two years by using in‐situ geological approach, and mining wastes and secondary minerals were recycled as resources for ex‐situ CO2 sequestration. However, geological activity is the major risk of in‐situ storage, while high energy consumption and associated cost may limit the application of ex‐situ carbonation. Significant technical breakthroughs of mineral and geological CO2 sequestration are therefore of vital importance to realize a “net‐zero CO2 emissions” and even “carbon‐negative” society.
