Carbon mineralization is a carbon dioxide removal (CDR) process that accelerates the reaction between CO2 and alkaline minerals (like those in basalt) to permanently store carbon as solid carbonates. While it offers potential co-benefits such as strengthened concrete and the neutralization of toxic mine tailings, scaling the technology poses risks including induced seismicity, high water usage in arid regions, and environmental impacts from increased mining. The document emphasizes the need for standardized measurement, reporting, and verification (MRV) protocols and updated mineral mapping to scale the process responsibly.

This guide introduces 'whole system design' for residential buildings, emphasizing the integration of passive solar strategies, thermal mass, and reflective roofing to reduce energy consumption. It argues that careful planning can make green homes cost the same or less than conventional ones and highlights financing options like Energy Efficient Mortgages (EEMs).
