Excise waiver for biogas blending, clear policy line can unlock Rs 1 lakh cr investment: IBA

The Indian Biogas Association said the proposed excise duty waiver on biogas blended in compressed natural gas could unlock investments of up to ₹1 lakh crore if supported by clear and stable policy. The Union Budget 2026 announced the waiver on compressed biogas (CBG) blended with CNG, which the industry body said will aid India’s energy transition and Net Zero target for 2070.
