This report evaluates emission mitigation options to achieve net-zero carbon emissions through marginal abatement cost (MAC) curves for the existing plants in the aluminium industry. In terms of overall metal consumption, aluminium ranks second, next only to steel. However, India’s per capita aluminium consumption is low, at 2.5 kilograms (kg), compared to the world average of 11 kg, and has potential for growth. Data was collected at various levels – state and country – along with some overarching assumptions, such as the uniform energy consumption across all aluminium plants in the country, and key inputs obtained from literature and conversations with industry experts.
