Industrial process emissions Industrial process emissions are the by-product of the conversion of raw materials to various metal, mineral and chemical products (such as iron and steel, cement, ferlisers and explosives).

Industrial process emissions
Industrial process emissions are the by-product of the conversion of raw materials to various metal, mineral and chemical products (such as iron and steel, cement, fertilisers and explosives). Industrial process emissions also include releases of synthetic gases used in refrigeration and air-conditioning. They exclude energy-related emissions—these are instead attributed to the electricity, direct combustion and transport sectors.
Industrial processes accounted for 32 Mt CO2-e (5 per cent) of Australia’s emissions in 2012. Metal production was the main contributor, followed by refrigerant gases, chemical processes and mineral production.
Future emissions depend on a range of factors including economic conditions and policy settings. With no new policy incentives, industrial process emissions are projected to grow strongly to 45 Mt CO2-e in 2030. This is primarily driven by strong mining sector demand for explosives and growing use of refrigerant gases, partly offset by falls in iron and steel production and increasing clinker imports in place of domestic production.
There are substantial cost-effective opportunities to reduce industrial process emissions, however. With a high price incentive, emissions could fall to 21 Mt CO2-e in 2020 and only 11 Mt CO2-e in 2030.
