What is the GST and excise position on CBG?

CBG historically faced a double-taxation problem at the blending point. Budget 2026-27 exempted central excise duty on the biogas or CBG portion of blended CNG, removing a barrier that had made CGD entities reluctant to pay the full rate. GST still applies and should be modelled explicitly in the DPR.
