# Non-energy GHG emissions
## Process CO2 emissions
Process CO2 emissions due to limestone calcination occuring the cement process are detailed in Table 2 of the section dedicated to [cement](../../docs/energy-sectors/industry/cement/index.md).
Process CO2 emissions due to the oxidation of carbon occuring in steel manufacturing processes are detailed in the section dedicated to [iron & steel](../../docs/energy-sectors/industry/iron-steel/index.md), Appendix 1.
## Other non-energy GHG emissions
Other non-energy GHG emissions include CO2, CH4, and N2O emissions from agriculture, forestry and land-use (AFOLU), as well as process N2O emissions from adipic industry and nitric industry.
