India's Biochar Opportunity: From Agricultural Waste to Carbon Credits
As India seeks to scale its carbon removal capacity, biochar production from agricultural residue could unlock significant value in both voluntary and compliance markets.
India's agricultural sector generates roughly 500 million tonnes of crop residue annually, most of which is burned in fields or left to decompose. This represents a substantial untapped resource for biochar production—a process that converts biomass into a stable carbon form while offering co-benefits in soil amendment and farm economics.
The carbon removal potential is meaningful. Biochar sequesters carbon for centuries when applied to soil, creating durable removal credits that appeal to corporate buyers seeking high-quality offsets. For India specifically, domestically produced biochar could support both Article 6 international carbon trading mechanisms and India's emerging domestic carbon market, while avoiding the verification challenges that plague some other CDR methodologies. The agricultural waste feedstock also sidesteps land-use competition issues central to debates around other nature-based solutions.
However, scaling biochar requires addressing several market constraints. Production costs remain high relative to carbon credit prices in voluntary markets, necessitating policy support through subsidies or carbon pricing floors. Supply chain infrastructure for collection, processing, and distribution is nascent. And standardized methodologies for measuring and verifying carbon claims need refinement to attract institutional capital. India's policymakers should consider targeted support for biochar as part of a diversified carbon removal strategy—not as a silver bullet, but as a complementary tool that leverages existing agricultural systems rather than competing with them.
