GHGRP 2016: Minerals
The minerals sector consists of cement production, glass production, lime manufacturing, soda ash manufacturing, and any other mineral production facility operating under NAICS codes beginning with 327 (Non-metallic Mineral Product Manufacturing). Facilities under this sector transform mined or quarried non-metallic minerals — such as sand, gravel, stone, clay, and refractory materials — into products for intermediate or final consumption. Glass, cement, soda ash and lime facilities report both process emissions from the calcination of carbonate-based raw materials and GHG emissions from stationary fuel combustion sources. All other mineral production facilities report only GHG emissions from stationary fuel 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. This sector includes the CO2 emissions reported for those processes.

What factors influenced the trend in emissions for minerals production?
- Location and emissions range for each reporting facility in the minerals sector (as of 8/5/17).
This map shows the locations of direct-emitting facilities. The size of a circle corresponds to the quantity of emissions reported by that facility.
