The iron and steel sector is the second-largest industrial user of energy, consuming 616 Mtoe in 2007 and is also the largest industrial source of CO2 emissions. The five most important producers – China, Japan, the United States, the European Union and Russia – account for over 70% of total world steel production. A main technology in the iron and steel industry is the direct casting, which is the process of creating finished iron and steel products using moulds to shape the molten metal. 

To accelerate the adoption of cleaner and more energy efficient technology in the Coimbatore metal-casting cluster by building capacities on both supply and demand sides with training for customers and service providers, and dialogue with government and financial institutions.
