Carbon Credits vs Direct Abatement for Indian Mining Companies
Indian mining companies face a practical question: should the next rupee go into cutting diesel and grid-power emissions at the mine, or into carbon credits? The honest answer is both, in a set order. This guide compares the two on cost and credibility for a sustainability or procurement lead at a mining company.
Where mining emissions actually sit
For most open-cast and underground operations, Scope 1 is dominated by diesel burned in haul trucks, excavators and drills, plus fugitive methane in coal mining. Scope 2 is grid electricity for ventilation, crushing, processing and, in metals, smelting. These are the emissions a mine controls directly, so they are where abatement should start. For the wider picture, see our guide to Scope 1, 2 and 3 emissions.
What direct abatement looks like in the field
Two publicly disclosed examples show the scale of what is achievable. Hindustan Zinc reported 6.7 lakh tonnes of CO2e in GHG savings in FY25, against an internal target of 5 lakh tonnes, and cut emission intensity 15% from its 2020 baseline. Its renewable share of power rose from 6% in FY24 to nearly 13% in FY25, and it targets 70% by FY28 through round-the-clock renewable power agreements of up to 530 MW.
Coal India shows the cost side. It spent ₹9.61 billion on solar capex up to January FY26, ahead of its full-year target, and reported project costs of ₹40–45 million per MW, down from ₹55–60 million. It had about 247 MW of renewable capacity at December 2025, expects 675 MW by the end of FY26, and targets 3 GW by FY28.
The lesson for a mid-size miner: renewable power and efficiency measures reduce emissions permanently and show up in your own inventory. Credits do neither.
Where credits fit, and the compliance picture
The CCTS notification of 13 January 2026 brought petroleum refineries, petrochemicals, textiles and secondary aluminium into the compliance framework, covering 208 obligated entities. It did not name mining. That means most miners currently buy credits voluntarily, which gives you freedom on timing but puts the full burden of credibility on you. Our India CCTS guide explains how the compliance market works, and our mining project-types post covers which credits suit a mining buyer.
Credits make most sense for three things:
Residual emissions that remain after efficiency and renewable power are exhausted, such as diesel with no near-term electric substitute.
Legacy-land restoration claims, where afforestation on mine-lease land can deliver credits and community benefit. See our ARR credits buyer's guide.
Interim cover during the two to three years before a captive solar or RTC power contract starts delivering.
A simple decision order for a mining sustainability lead
Quantify Scope 1 diesel and Scope 2 electricity separately, by site.
Price each abatement option per tonne over its life, including capex per MW and fuel savings.
Rank options from cheapest per tonne upward, and execute everything that costs less than a high-quality credit.
Buy credits only for the remainder, with registry-verified, additional projects and a documented retirement trail.
Disclose the split between reductions and offsets clearly, to avoid greenwashing risk.
Credit prices vary widely by project type and vintage, so check current quotes rather than relying on a headline average. Our carbon credit price guide explains what drives the range, and our RFP template gives you 27 questions to put to any seller.
Bottom line
For a mining company, credits are a supplement to abatement, not a substitute. Direct reductions in diesel and power are cheaper to defend to auditors, lenders and customers; credits close the gap that is left. Done in that order, your climate claims stay credible even if mining later comes under CCTS targets.
