With a gross state domestic product (GSDP) of INR 23.64 lakh crore in 2022–23, Tamil Nadu (TN) contributes nearly 10 per cent to India’s overall gross domestic product (GDP). As a leading industrial state, it has an ambitious target of becoming a USD 1 trillion economy by 2030–31. Given that TN is a growing economy with a stabilising population, its energy needs are also expected to significantly increase in the future, notably in key sectors such as transport, industry and building. In this context, the Government of Tamil Nadu embarked upon an exercise to develop the state’s long-term net-zero (NZ) emissions transition plan. TN undertook a scientific and rigorous energy systems modelling exercise to inform the state’s vision and sectoral pathways to achieve NZ emissions.
