The Scorched Ledger: Counting the True Cost of Climate Change in India

Climate change is no longer a distant environmental threat but an immediate economic crisis for India, where conventional GDP-based accounting systematically understates the true burden. Conventional metrics overlook the erosion of ecosystem services, the hidden losses in the vast informal economy, and the non-market costs of health and human suffering. Drawing on district-level, large-scale household surveys, geospatial climate datasets, computable general equilibrium modelling, and a systematic synthesis of over 300 peer-reviewed studies, this paper offers one of the most comprehensive valuations yet undertaken. The analysis estimates India’s current annual climate-related economic losses at ₹7–10 lakh crore—roughly 4–6 % of GDP. These figures are rising sharply and could reach 12–18 % of GDP by 2050 under high-emissions pathways. The impacts are starkly unequal: the poorest households lose three to five times more of their income than the national average; women and children bear disproportionate health and care burdens; and climate-vulnerable states in central and eastern India suffer losses far exceeding the national mean. Yet the ledger is not only about costs. Adaptation investments deliver benefit-cost ratios of 4:1 to 8:1, while ambitious mitigation pathways generate substantial long-term savings through reduced fossil-fuel imports, new green jobs, and avoided damages. The findings make a compelling economic case for urgent, equity-centred climate action. They also expose the urgent need for “green national accounting” that incorporates natural capital, carbon pricing that recycles revenues into social protection, and institutional reforms that place climate economics at the heart of development planning. Recognising the true scorched ledger is the first step towards a sustainable and inclusive India.
