India has since 2010 made noteworthy progress on fossil fuel subsidy reform through a calibrated 'remove', 'target', and 'shift' approach, the Asian Development Bank (ADB) said in a new report. "By carefully balancing the combined effect of three key policy levers - retail prices, tax rates, and subsidies on selected petroleum products - the country was able to reduce its fiscal subsidy in the oil and gas sector by 85 per cent, from an unsustainable peak of USD 25 billion in 2013 to USD 3.5 billion in 2023," it said.
