Greenhouse Gas Reporting Program

Minerals

The minerals sector consists of cement production, glass manufacturing, lime production, and any other mineral production facility operating under NAICS codes beginning with 327 (Nonmetallic Mineral Product Manufacturing). Facilities under this sector transform mined or quarried nonmetallic minerals, such as sand, gravel, stone, clay, and refractory materials, into products for intermediate or final consumption. Glass manufacturing facilities and all cement and lime facilities report both process emissions from the calcination of carbonate-based raw materials and GHG emissions from stationary combustion sources. All other mineral production facilities report only the GHG emissions from stationary combustion sources. A small number of facilities in this sector collect CO2 either for use in their other production processes (e.g., sugar refining), to transfer to other users, or to sequester or otherwise inject underground. Process emissions reported under this sector include this CO2.
