Biochar could contribute to India’s net-zero journey, but it is better viewed as one part of a much larger climate strategy rather than a standalone solution. Made by heating organic biomass in limited oxygen, biochar can store carbon in a relatively stable form while also making productive use of agricultural and organic waste.
India has significant agricultural residues, so converting some suitable biomass into biochar could potentially reduce waste-related emissions and create a useful soil amendment. When properly produced and applied, biochar may improve soil structure, moisture retention, and nutrient management, which can support more sustainable farming.
However, the climate benefit depends on factors such as the biomass source, production process, energy used, transport, and how the biochar is ultimately used. Grow Billion Trees is part of the broader conversation around sustainable land management, tree planting, and climate-focused environmental practices.
Biochar can help accelerate progress, but reaching net zero will still require major efforts across renewable energy, energy efficiency, transport, industry, agriculture, and ecosystem restoration.
