Pulp & Paper Sector CCTS Exposure: Deep Deficit and Decarbonization Challenges

India's 53 obligated pulp and paper facilities face a net-short compliance position under the Carbon Credit Trading Scheme (CCTS). With a weighted average rate (WAR) of 2.83% and a projected cumulative deficit of approximately 3.2 lakh credits by FY 2029-30, the sector faces an estimated INR 124-128 crore liability. The GEI notification from October 2025 has established facility-level baselines, revealing extreme heterogeneity in emissions intensity across integrated mills, recycled fibre (RCF) plants, and agro-based mills—each with distinct decarbonization pathways and capital constraints.

Sector Overview

Pulp & Paper Sector Dynamics

India's pulp and paper industry comprises three distinct facility types, each with different emission profiles and decarbonization challenges. Integrated mills combine pulping, bleaching, and papermaking on-site, enabling energy recovery through black liquor combustion and waste heat integration. Recycled fibre (RCF) plants process waste paper with lower process emissions but often rely on purchased power. Agro-based mills utilize agricultural residues and process them into pulp, creating distinct supply chain and fuel dynamics.

Pulp and paper manufacturing is inherently carbon-intensive due to three primary emission sources: the pulping process (separation of cellulose fibers under high temperature and pressure), bleaching operations (use of chemical oxidants), and drying cycles (energy-intensive thermal processes). These process emissions combine with scope 2 emissions from purchased electricity to create a sector-wide net-short position under CCTS.

Extreme Facility Heterogeneity

The 53 obligated facilities display material variation in baseline emissions intensity. Integrated mills with modern recovery boilers, efficient bleaching chemistry, and waste heat utilization already operate near leading international performance levels (benchmarked against Northern Europe and East Asia). RCF plants vary widely based on production scale and furnace efficiency. Agro-based mills face particular challenges: feedstock quality variability, often older process equipment, and limited access to advanced abatement technologies create compliance burdens that smaller producers cannot easily address.

This heterogeneity creates material compliance swings. A modern integrated mill with integrated combined heat & power and biomass fuel may approach or achieve surplus; a smaller agro-based mill faces structural deficit requiring substantial capital investment or ongoing credit procurement.

Decarbonization Levers & Constraints

The pulp & paper sector has multiple decarbonization pathways, but each faces capital or operational constraints:

• Recovery Boiler Efficiency: Upgrading recovery boilers to higher efficiency reduces both energy demand and emissions. However, capex is substantial (INR 50-100+ crore for large mills), with 5-7 year payback dependent on energy cost savings.
• Biomass Fuel Switching: Substituting purchased coal or grid electricity with biomass or waste-derived fuels is effective but limited by feedstock availability. Smaller mills often lack scale to secure stable biomass supply contracts or process residues at competitive costs.
• Process Optimization: Reduced bleach consumption, shorter cooking cycles, and optimized drying reduce both emissions and operating costs. These are lower-capex improvements but offer diminishing returns once baseline efficiency is achieved.
• Renewable Energy Procurement: Rooftop solar, wind PPAs, or renewable power purchase agreements reduce scope 2 emissions. However, RCF and agro-based mills often lack balance sheet capacity for large renewable capex or long-term PPA commitments.

Capital & Biomass Sourcing Limitations

For smaller facilities and agro-based mills, capital availability constrains decarbonization ambition. A recovery boiler upgrade or large renewable energy investment requires sustained capex that many producers cannot support, particularly those already facing margin pressure from commodity price volatility.

Biomass sourcing is equally critical: agro-based mills depend on stable access to agricultural residues (rice straw, sugarcane bagasse, etc.), but competing uses (animal feed, bioenergy, soil amendment) create supply volatility and rising feedstock costs. This creates a vicious cycle: mills that cannot secure renewable fuels face higher emissions intensity, steeper compliance deficits, and larger credit procurement costs.

Strategic Implications

The pulp & paper sector's projected INR 124-128 crore CCTS liability by FY29-30 reflects both the sector's high process emissions and the limited ability of many facilities to decarbonize at pace. Integrated mills with modern infrastructure and strong balance sheets can manage compliance through a mix of operational efficiency and renewable energy procurement. Smaller and agro-based mills face structural challenges: they must either secure capital for material process upgrades, lock in long-term biomass supply, or accept ongoing carbon credit procurement as a permanent cost of operation.
