Carbon Credits for Paper Mills in India: Which Project Types Actually Fit

Indian paper and pulp mills are on the list of sectors covered by the Carbon Credit Trading Scheme (CCTS), which makes the question practical rather than theoretical: which credits should a mill actually buy or generate? The answer differs from a cement plant or a refinery, because a paper mill sits on top of a renewable raw-material chain. This guide explains which project types fit a paper-sector buyer and which do not.

Why paper mills are a different kind of credit buyer

A paper mill's emissions come from three places: boilers and captive power burning coal or biomass, lime kiln and chemical recovery operations, and purchased electricity and fibre transport. Many mills already burn biomass and black liquor, whose CO2 is treated as biogenic, so the fossil share of the footprint is concentrated in coal-fired steam and power.

That has a direct consequence. Compliance under the scheme is measured against an emission-intensity target, so a mill's first lever is fuel switching and steam efficiency. Credits are the second lever, used for the residual gap and for voluntary claims. For background on how the scheme works, see our CCTS guide and our earlier pulp and paper sector post.

Project types that suit a paper-sector buyer

Not every credit fits. Here is how the main categories look from a paper company's seat:

• Afforestation, reforestation and revegetation (ARR). The most natural fit. Paper companies already work with farmers on plantations, so an ARR project can sit beside an existing fibre programme, provided the trees are genuinely additional and not simply the pulpwood the mill would have planted anyway. The Bureau of Energy Efficiency published an offset methodology for afforestation and reforestation of lands other than wetlands (BM FR05.002, version 1.0, effective 8 September 2025), which opens a domestic route for this project type.

• Biomass and renewable energy projects. Credibility is mixed. Additionality is hard to prove where biomass use is already commercially standard, so buyers should scrutinise baselines closely.

• Energy-efficiency and waste-heat projects. Useful, but often better captured inside the mill's own intensity performance than bought from others.

• Cookstove and household-level projects. Available in volume, but quality varies widely, so a rigorous check against integrity criteria is essential. See our guide to evaluating high-integrity credits.

The additionality trap with plantation credits

A paper mill that buys or generates tree-based credits faces a question every verifier will ask: would this planting have happened anyway? Captive and farm-forestry plantations are commercial activities driven by pulpwood demand. If the trees are harvested on a short rotation for the mill's own feedstock, long-term carbon storage and permanence are limited, and the credit claim is weak.

Stronger designs include long-rotation or permanent stands, degraded or non-commercial land, and Miyawaki-style native-species plantations where the objective is carbon and biodiversity rather than fibre. Read how registry rules treat this in our ARR and VM0047 buyer's guide and see our afforestation services for implementation support.

A practical buying checklist for a sustainability or procurement head

• Quantify first: establish verified Scope 1 and 2 emissions and your intensity position against your target before approaching the market.

• Separate compliance from voluntary needs: only credits recognised under the scheme count toward a regulatory shortfall; other credits serve voluntary claims.

• Demand project-level evidence: baseline, additionality test, monitoring data and a registry serial number you can retire against.

• Check permanence terms: ask what happens if trees are lost to fire or harvest, and whether a buffer pool covers it.

• Stage purchases: contract across vintages rather than buying a single large block, as market rules and prices are still settling.

For pricing and RFP structure, our RFP template lists the questions worth putting to any seller, and our carbon credits service page explains how we source and retire credits.

Bottom line

For a paper mill, credits work best as a complement to decarbonising steam and power, with afforestation-based projects the most credible fit when designed for permanence and additionality. Buy the residual, document the integrity, and avoid treating existing pulpwood plantations as offsets.
