Why Biochar Could Be India's Most Scalable Carbon Removal Solution

India produces over 500 million tonnes of agricultural residue annually. Most of it is burned—releasing CO₂ and particulate matter into the atmosphere. Biochar offers a different path: turn that residue into stable carbon that stays in the soil for centuries.

Biochar is a charcoal-like substance produced by heating organic matter in a low-oxygen environment—a process called pyrolysis. Unlike regular charcoal, it's engineered for soil amendment and carbon storage. When added to soil, it improves water retention, nutrient availability, and—critically—sequesters carbon for hundreds of years.

What is Biochar?

The science is well-established. Pyrolysis converts roughly 50% of biomass carbon into stable aromatic structures that resist decomposition. Studies show biochar can remain in soil for 500-1,000 years, making it one of the most permanent forms of nature-based carbon removal.

India could sequester 50-100 million tonnes of CO₂ annually through biochar by 2030—if we build the infrastructure now.

India's Unique Advantage

We have the feedstock. Rice straw, sugarcane bagasse, coconut shells, and crop stubble—all currently burned or left to decompose—could feed a thriving biochar industry. The Ministry of New and Renewable Energy has already identified biomass as a priority. Carbon removal adds a revenue stream that makes pyrolysis economically viable.

Verification and Permanence

Industry standards like Gold Standard and Puro.earth have developed methodologies for biochar carbon credits. The key is traceability: from feedstock source to final soil application. CarbonX is piloting biochar projects in Maharashtra and Karnataka.
