A practical roadmap for India’s mining industry to achieve Carbon Neutral Mining operations through innovation, policy alignment, and sustainability leadership.
India’s mining industry has long been the backbone of its industrial and infrastructure growth. From coal and iron ore to bauxite and rare earth minerals, mining fuels power generation, steel production, construction, and even clean energy technologies themselves.
Yet, this sector is also one of the most carbon-intensive. According to the Ministry of Mines (GoI), India’s mining operations account for nearly 6–7% of total national greenhouse gas (GHG) emissions, driven by fossil-fuel-based energy, inefficient logistics, and lack of sustainable extraction technologies.
As India moves towards net-zero emissions by 2070, the pressure is mounting on heavy industries including mining to adopt cleaner, more efficient, and carbon-neutral practices. The challenge, however, lies in balancing economic dependence on mining with environmental responsibility.
The good news? With the right strategies, policies, and technological innovation, carbon-neutral mining is achievable. This article explores five key strategies India can adopt to move toward sustainable, low-carbon mining while staying globally competitive.
1️⃣ Transitioning to Renewable Energy Sources in Mining Operations

3️⃣ Circular Economy and Waste Valorization
From Waste to Wealth
Mining produces vast amounts of waste—tailings, slag, and dust—that often go unused or cause environmental damage. A circular economy approach can transform waste into valuable resources, significantly reducing the sector’s carbon footprint.
Circular Practices Include:
Water Recycling: Closed-loop water management systems reduce water consumption and contamination.
Mine Waste Recycling: Tailings can be repurposed into construction materials such as cement additives or road aggregates.
Metal Recovery from Waste: Technologies like bioleaching and hydrometallurgy recover valuable minerals from low-grade ores and waste.
Re-mining Abandoned Sites: Recovering residual metals from old dumps prevents new extraction while reclaiming degraded land.
Global Example:
- Boliden (Sweden) reuses smelter dust and tailings to recover metals, reducing virgin extraction by 30%.
- Freeport-McMoRan (USA) recycles mining wastewater, cutting freshwater usage by 80%.
India Example:
- Tata Steel operates with a zero-waste mining policy, recycling over 90% of its solid waste.
- NALCO (National Aluminium Company) uses red mud for brick-making and road construction under its waste valorization initiative.
Implementation Tip:
Adopt mandatory Extended Producer Responsibility (EPR) frameworks within the mining industry to ensure companies reclaim and repurpose their waste streams.
4️⃣ Carbon Capture, Utilization, and Storage (CCUS) in Mining Processes
Capturing Emissions Before They Escape
While transitioning to renewables will take time, carbon capture and utilization (CCU) technologies offer an immediate pathway to mitigate emissions from ongoing fossil-based operations, especially in coal and metal refining.
Key Techniques:
- Post-Combustion Capture: Captures CO₂ from flue gases in thermal plants or smelters for reuse.
- Carbon Mineralization: Converts captured CO₂ into solid carbonates for construction material.
- Biochar Integration: Uses biochar (from biomass waste) in soil remediation at mined sites, sequestering carbon naturally.
- CO₂-to-Fuel Conversion: Emerging technologies can transform captured carbon into synthetic fuels.
Global Example:
- ExxonMobil’s LaBarge facility (USA) captures nearly 7 million tonnes of CO₂ annually.
- Glencore is testing CCUS at its metallurgical operations to neutralize Scope 1 emissions.
India Example:
- NTPC and Indian Oil Corporation have initiated pilot projects in CCUS for their power and refining units, offering potential models for the mining industry.
- The Central Mine Planning & Design Institute (CMPDI) is exploring coal mine methane (CMM) recovery, which reduces emissions while producing clean fuel.
Implementation Tip:
Create a National CCUS Roadmap for Mining, integrating policy support, fiscal incentives, and international collaboration to pilot carbon-neutral zones in mining districts.
5️⃣ ESG Integration and Data-Driven Sustainability Reporting
Transparency is the New Currency
The mining industry faces increasing scrutiny from investors, regulators, and communities on its Environmental, Social, and Governance (ESG) performance. Transparent, data-driven ESG reporting helps track progress toward carbon neutrality and enhances credibility.
Strategic Steps:
- Measure & Monitor Emissions: Use IoT-enabled carbon accounting systems to measure Scope 1, 2, and 3 emissions across supply chains.
