India 2026 SBTi Roadmaps and MACC for Industrial Net Zero Planning

India’s industrial decarbonisation agenda is moving from disclosure to execution. By 2026, large emitters are facing pressure from multiple directions at once: BRSR Core data quality, export-market carbon scrutiny, internal energy-cost volatility, investor questions on transition plans, and the need to lock in credible emissions reductions rather than publish broad ambition statements.

For many companies, the missing link is not intent. It is planning discipline. A credible net-zero journey requires two things working together: an SBTi-aligned decarbonisation roadmap and a marginal abatement cost curve, or MACC, that helps management prioritise actions by cost, feasibility and timing.

This article explains how Indian corporates can build an actionable 2026 roadmap that translates emissions baselines into sequenced capex, operating changes, procurement strategy and governance. The focus is on practical use by C&I energy consumers, RE developers, lenders, utilities and policymakers.

Why SBTi and MACC matter in 2026

Science-based target setting is no longer just a branding exercise. For Indian manufacturers, data-centre operators, commercial portfolios and diversified corporates, a robust target architecture increasingly affects customer access, procurement qualification, lending conversations and board oversight.

At the same time, a target by itself does not tell management where to spend the next rupee. That is where a MACC becomes essential.

An SBTi-aligned roadmap answers questions such as: - What is the baseline for Scope 1, Scope 2 and material Scope 3 categories? - What level of reduction is required by 2030, 2035 and 2040? - Which interventions are operationally feasible within asset life cycles? - What residual emissions are likely to remain in hard-to-abate processes?

A MACC answers a different but related set of questions: - Which interventions cut the most emissions per year? - Which options save money today versus those that require a carbon price or policy support? - Which actions are no-regret, which are strategic, and which should be deferred? - How should projects be sequenced to avoid stranded capex?

In practice, companies need both. An SBTi pathway creates the destination. A MACC creates the execution map.

Start with a boundary that reflects business reality

Many decarbonisation plans fail because the emissions boundary is set for convenience rather than decision-making. In 2026, that approach is risky.

A useful starting point for Indian industry is to establish: - Organisational boundary: equity share or operational control - Operational boundary: Scope 1, 2 and relevant Scope 3 categories - Facility-level granularity: plant, process line, utility block and logistics interface - Data hierarchy: metered data first, then invoices, then engineering estimates where necessary

This is particularly important for companies with multiple fuels, captive generation, contract manufacturing, imported raw materials or export-oriented product lines.

For example, a ceramics, steel re-rolling, chemicals or food-processing company may find that enterprise-level averages hide major variation between facilities. One plant may have low-cost waste-heat recovery potential; another may be suitable for open-access solar and round-the-clock hybrid power; a third may require thermal process redesign. Without plant-level segmentation, the roadmap becomes generic and unbankable.

This is also the stage where companies should connect Carbon accounting & disclosure with capital planning. If emissions data sits only with sustainability teams and not with operations, procurement and finance, the roadmap will not survive budget season.

Build the baseline: emissions, energy cost and abatement levers

A 2026-ready baseline should not stop at tonnes of CO2e. It should integrate three layers: - Emissions baseline: by source and scope - Energy baseline: electricity, coal, petcoke, furnace oil, diesel, gas, steam and process heat - Cost baseline: tariff, fuel cost, demand charges, wheeling and banking, O&M and maintenance loss points

For most Indian C&I consumers, electricity is still a major near-term reduction lever because grid emission factors remain material and RE procurement economics are often favourable. Depending on state, contract structure and load shape, solar open-access or group captive landed costs in 2026 may still be competitive in the broad range of Rs 3.2-4.8 per kWh, while C&I grid tariffs in many states remain around Rs 6.5-10 per kWh once energy charges, demand charges, duty and other components are considered. Hybrid structures and storage-backed solutions vary more widely, but the cost gap still justifies close analysis for many day-load consumers.

However, the baseline must also identify where electricity is not the main story. In sectors such as cement, metals, fertilisers, glass, ceramics, chemicals and textiles, direct fuel combustion and process emissions may dominate. In these cases, the MACC should include: - Energy efficiency retrofits n- Waste heat recovery - Burner and boiler optimisation - Fuel switching from coal or liquid fuel to gas where viable - Electrification of low- and medium-temperature heat - Biomass or biofuel substitution where supply reliability is credible - Green hydrogen pilots for specific hard-to-abate applications - Process chemistry changes - Circularity and scrap use improvements - Logistics optimisation

For exporters, CBAM exposure can also shift priorities. Even before full cash impacts become immediate, product-level carbon data discipline can influence customer retention and contracting.

How to construct a practical MACC for Indian industry

A MACC should not be a presentation graphic made from generic assumptions. It must reflect Indian operating conditions, tariff structures, asset age and plant constraints.

At minimum, each abatement measure should be evaluated across the following parameters: - Annual abatement potential in tCO2e - Capex requirement in Rs crore - Opex impact per year - Levelised abatement cost in Rs per tCO2e avoided - Payback period and IRR - Implementation time - Outage requirement - Technology maturity - Policy dependence - MRV complexity

A useful way to classify options is: - Negative-cost measures: save money and reduce emissions - Low-cost strategic measures: modest positive cost but high implementation readiness - Long-lead transformation measures: larger capex, process redesign or infrastructure dependency - Emerging options: pilot-scale or policy-sensitive

For many Indian industrial sites in 2026, the first part of the MACC often includes compressed-air optimisation, variable frequency drives, motor replacement, steam-system repairs, power-factor correction, heat recovery, digital energy management and selected utility upgrades. These can deliver abatement at low or negative cost when implemented well.

The next layer typically includes RE-led Scope 2 reduction through rooftop solar, open-access solar, wind-solar hybrid, group captive structures, storage for selected duty cycles, and procurement redesign. The financial attractiveness depends on state policy, approved charges, banking rules, contract tenure and hourly load match.

Then come harder decisions: electrifying process heat, replacing fossil-fired equipment before end of life, introducing green hydrogen in niche use cases, altering feedstocks, or investing in new process configurations.

This is where Net-zero roadmaps & MACC becomes a board tool rather than a sustainability tool. Management can see what can be done now, what must be aligned with the next capex cycle, and what depends on external market development.

Sequence actions by asset life, not by presentation logic

A common mistake is to rank projects only by current abatement cost. That can lead to delay in strategic actions that require early design decisions.

A stronger approach is to sequence decarbonisation in four tracks.

• Track 1: no-regret measures, 0-24 months
• - Utility efficiency
• - Process controls
• - Heat recovery
• - Leak reduction
• - Metering and sub-metering
• - RE procurement optimisation

• Track 2: capex-light structural moves, 1-3 years
• - Rooftop solar where load profile fits
• - Open-access or captive RE sourcing
• - Diesel displacement
• - Fleet and internal logistics efficiency
• - Refrigeration and HVAC upgrades in commercial or cold-chain assets

• Track 3: capex-cycle integration, 2-7 years
• - Boiler and furnace replacement planning
• - Electrification of low- and medium-temperature heat
• - Process redesign during turnaround cycles
• - Product mix optimisation
• - Supplier engagement for high-impact Scope 3 categories

• Track 4: long-horizon transformation, 5-15 years
• - Green hydrogen for hard-to-abate thermal applications
• - New process routes
• - CCUS only where sector-specific economics and storage/logistics are credible
• - Deep material substitution and circular business models

This sequencing matters because industrial decarbonisation is constrained by outage windows, debt covenants, working capital, land, interconnection, and environmental clearances. A roadmap that ignores these realities may look ambitious but will underdeliver.

Integrate finance, policy and carbon-market exposure

In India, decarbonisation economics are increasingly shaped by policy architecture rather than engineering alone. By 2026, companies should test their roadmaps against at least five external variables: - State electricity policy and open-access charges - Renewable procurement rules and banking provisions - Fuel price volatility, especially gas and imported coal exposure - India CCTS evolution and allowance-price scenarios where relevant - International trade exposure, including product carbon reporting requirements

This is especially important for lenders and infrastructure investors evaluating transition credibility. A decarbonisation roadmap should show not just emissions ambition, but funding logic: - Which projects are balance-sheet funded? - Which can be structured through third-party supply or service models? - Which measures improve EBITDA through energy-cost reduction? - Which projects are contingent on future carbon-price signals?

Scenario analysis is useful here. For example, a process electrification measure that appears expensive under current tariffs may become viable if paired with dedicated renewable sourcing, time-of-day load management and future fossil-fuel escalation. Similarly, a fuel-switch project with a marginal business case today may strengthen under tighter export-market carbon scrutiny.

For companies expecting future interaction with India’s carbon market architecture, Carbon markets & MRV should be embedded early. If abatement performance cannot be measured cleanly at the asset level, future monetisation, compliance readiness and internal performance tracking all become harder.

What a board-ready 2026 roadmap should include

A credible industrial net-zero roadmap should be concise enough for leadership decisions but detailed enough for plant execution. At minimum, it should include:

• Baseline year and emissions inventory by scope
• Business growth assumptions and production normalisation
• SBTi-aligned target pathway or equivalent science-based reduction logic
• Facility-wise and process-wise abatement levers
• MACC with clear methodology and assumptions
• Capex and opex implications by phase
• Ownership matrix across operations, procurement, finance and sustainability
• RE sourcing strategy linked to load profile and state regulations
• Scope 3 engagement plan for priority categories
• MRV framework for internal review, assurance and external disclosure
• Risks, dependencies and trigger points for revising the roadmap

Boards should also ask three difficult questions.

• Are we relying too heavily on low-credibility offsets or undefined future technologies?
• Are we postponing key decisions because current-year economics look tight, even when asset replacement timing makes delay costly later?
• Do we have plant-level data quality strong enough to defend our claims with customers, auditors and lenders?

These questions matter because industrial decarbonisation in India is now entering an implementation decade. Companies that move early can capture lower energy cost, stronger customer positioning, better financing conversations and better readiness for carbon-linked regulation. Those that delay may end up paying for rushed compliance, poorly timed capex and inconsistent data systems.

The practical takeaway for Indian industry

In 2026, the most effective decarbonisation programmes are not the ones with the most ambitious headline targets. They are the ones that connect emissions accounting, engineering reality, commercial structuring and policy exposure into one operating plan.

For Indian C&I consumers, that usually means three immediate priorities: - Clean up the baseline and plant-level data architecture - Build a MACC grounded in actual tariffs, fuel mix and asset condition - Sequence reductions around RE procurement, efficiency, electrification and long-lead process decisions

This is the point where sustainability becomes industrial strategy. Companies that treat SBTi and MACC as living management tools rather than annual-report content will be better positioned to reduce cost, protect market access and make decarbonisation investable.
