Carbon opportunities in sugarcane, CBG and biochar: what Indian sugar mills need to know

Indian sugar mills are moving beyond sugar and ethanol into compressed biogas, biochar and soil carbon projects. A new AgroSpectrum India report says the real opportunity is not just producing greener products, but turning their environmental attributes into verified, bankable revenue streams through India's developing carbon market. Ethanol blending already hit 20 percent in the 2025-26 supply year, and Maharashtra has a large base of ethanol units, so the policy push is real. However, the article warns that carbon credits require additionality. An activity that is already mandated by law or profitable without carbon revenue may not qualify. Sugar mills must separate renewable gas certificates, renewable energy certificates and carbon credits through a transparent registry, or risk double counting. For CBG, one RGC represents 1 MMBtu of gas, which is not the same as one tonne of CO2e reduction. The bottom line: the technical pieces already exist, from bagasse power to biochar. The test is whether monitoring, reporting and verification can make these benefits credible to buyers. That will decide whether carbon finance becomes a real revenue line for India's sugar sector.

The additionality section is the one to read. Ethanol blending is already mandated, so claiming a carbon credit for the same displacement is double counting. The article is right that the test is whether credits are additional and verifiable, not just whether the activity looks green.

Bagasse power is not new. The interesting part is whether it displaces coal at the margin and whether the mill can prove it. If the same electricity gets an REC, then a carbon credit claim needs an adjustment. That chain of custody is the hard part.

The RGC part is worth reading. One RGC equals 1 MMBtu of CBG, which is not the same as a tonne of CO2e. The carbon benefit depends on feedstock and what fuel it displaces. Mixing those units is a fast way to overstate climate impact.

Biochar gets a mention but not enough detail. Its climate value depends on how long the carbon stays stable in soil and what would have happened to the biomass anyway. The article is right to separate temporary storage from durable removal.

Good overview of the sugar mill as biorefinery. The real test is whether environmental attributes can be monetised through registries that prevent double counting. India's carbon market will live or die on that.
