India 2026 SBTi Roadmaps and MACC for Industrial Net Zero Planning

Indian industrial companies are under pressure to move from emissions disclosure to investment-grade decarbonisation plans. Export exposure, customer requirements, lender diligence, BRSR Core assurance, and internal cost-control targets are all pushing management teams to answer the same practical question: which carbon-reduction measures should be implemented first, at what cost, and on what timeline?

For many companies, the most effective answer in 2026 is to combine an SBTi-aligned target architecture with a marginal abatement cost curve, or MACC. The target sets the destination. The MACC helps decide the route.

This article explains how Indian commercial and industrial energy users can build a usable decarbonisation roadmap from plant data, commercial assumptions, and policy realities. It focuses on practical sequencing across Scope 1, Scope 2 and selected Scope 3 levers, with numbers and decision rules relevant to Indian industry.

Why SBTi and MACC matter together in 2026

Many decarbonisation plans fail for a simple reason: they either set an ambition without an implementation logic, or they produce a list of projects without a target framework that external stakeholders can trust.

SBTi helps companies define emissions-reduction targets consistent with climate science. For Indian corporates, that matters not just for reputation, but for customer qualification, supply-chain positioning, and capital access. Global buyers increasingly expect suppliers to show time-bound target pathways rather than generic net-zero statements. At the same time, domestic reporting and assurance expectations are becoming tighter. Boards, lenders and procurement teams now want evidence that emissions claims can be tied to actual capex, opex, energy sourcing and production planning.

A MACC brings this discipline into the roadmap. It ranks abatement options by cost per tonne of CO2e avoided, while also showing cumulative reduction potential. In practice, the MACC allows management to identify:

• Negative-cost measures that save money while cutting emissions
• Low-cost measures that can be deployed at scale in the next 12-36 months
• Strategic measures that are currently expensive but may become necessary for long-term target achievement
• Measures that should be deferred pending policy support, technology maturity or cheaper power supply

For Indian industry in 2026, this is particularly important because the decarbonisation toolkit is no longer limited to rooftop solar and energy audits. Companies now have to evaluate open-access renewable power, storage-backed supply, process electrification, waste heat recovery, fuel switching, biomass, renewable thermal options, green hydrogen pilots, logistics changes, refrigerant management, and supplier-engagement strategies.

Start with a target architecture, not a project list

Before building a MACC, companies should define a target architecture that is coherent across legal entities, plants, and scopes. This does not mean publishing a polished public commitment on day one. It means internally deciding what the company is actually trying to achieve.

Key design choices include:

• Base year selection, often FY 2022-23 to FY 2024-25 depending on data quality and business changes
• Target boundary: standalone entity, consolidated India operations, or global footprint
• Scope coverage: Scope 1 and 2 first, with priority Scope 3 categories phased in
• Absolute versus intensity targets for different business lines
• Near-term target horizon, typically 2030, and long-term net-zero horizon
• Treatment of acquisitions, divestments and capacity expansion

A steel reroller, a chemicals producer, and a food processor will not have the same target logic. For example, if output is expected to grow 40-60% by 2030, an intensity lens may be necessary for internal planning even where absolute reduction is required for external alignment. Similarly, multi-plant companies need to identify whether one flagship site will drive most low-cost reduction, or whether a common portfolio approach works across facilities.

This is where robust Carbon accounting & disclosure becomes foundational. If energy, fuel and production data are not standardised at plant level, the MACC will be unreliable and the target pathway will be difficult to defend in front of auditors, customers or lenders.

Building a plant-level emissions baseline for Indian industry

The baseline should be granular enough to support project decisions. At a minimum, companies should map emissions by:

• Plant and process line
• Fuel type: grid electricity, captive power, coal, petcoke, furnace oil, diesel, natural gas, LPG, biomass and others
• End use: steam, direct heat, motors, compressed air, chillers, HVAC, transport and process-specific equipment
• Production output and product mix
• Operating profile: base load, seasonal load, peak demand and maintenance schedules

For Scope 2, 2026 planning must distinguish between location-based and market-based outcomes, especially where renewable procurement instruments are being used. Open-access solar or hybrid procurement, group captive structures, and bilateral arrangements can materially change market-based emissions and power cost, but the contractual and settlement design has to be correctly reflected.

For Scope 1, many Indian industrial sites still underestimate fugitive emissions, diesel in internal logistics, and thermal inefficiencies in boilers, ovens, kilns or dryers. Even before major technology changes, baseline correction often reveals 3-8% avoidable emissions due to poor combustion control, excess steam losses, oversized motors, compressed-air leakage and low power quality.

Data collection should also capture cost inputs, because a MACC is not an engineering-only tool. Typical inputs include:

• Grid tariff and demand charges, often Rs 6.5-10.5 per kWh for HT industrial consumers depending on state and load pattern
• Open-access landed renewable tariff, often around Rs 4.0-6.5 per kWh depending on state, banking, wheeling, CSS and project structure
• Natural gas delivered cost, highly variable by region and contract type
• Coal, petcoke and biomass delivered energy cost on a useful-heat basis
• O&M cost and downtime impacts
• Cost of capital and hurdle rate, often 11-16% for internal industrial capex screening
• Expected equipment life, residual value and replacement cycle

Without these cost inputs, a MACC becomes a theoretical emissions chart rather than a decision tool.

What a good MACC includes and how to interpret it

A robust MACC for 2026 should not only plot cost per tCO2e and abatement potential. It should also indicate implementation timing, dependency on other measures, financing route, and policy sensitivity.

In Indian industrial settings, common abatement levers typically fall into four buckets.

• Operational efficiency and controls
• Renewable electricity and power procurement
• Fuel switch and process electrification
• Hard-to-abate technology options and value-chain interventions

Negative-cost and low-cost measures usually come first. These often include:

• Variable frequency drives on pumps and fans
• Compressed air system optimisation
• Waste heat recovery where quality of heat is usable
• Boiler tuning and condensate recovery
• Power factor and harmonic correction
• Chiller optimisation and thermal storage in suitable facilities
• Demand-side load management to reduce peak charges

These measures can often deliver abatement at below zero to Rs 1,500 per tCO2e avoided, depending on baseline inefficiency and power tariff. Payback may range from under 12 months to 3 years.

The next large block is often renewable electricity. For many C&I consumers, RE-led Scope 2 reduction remains the cheapest large-scale decarbonisation lever in 2026. If a plant is paying Rs 8.0-9.5 per kWh blended grid tariff and can access solar, wind-solar hybrid or group captive supply at a landed cost of Rs 4.5-6.0 per kWh, the emissions reduction can come with substantial cost savings. Even after accounting for banking changes, cross-subsidy surcharge where applicable, transmission and balancing, the business case is often strong for high day-time loads and stable annual consumption.

The challenge is not whether renewable electricity is attractive. It is how much of the load can be matched operationally, whether the state policy supports viable open access, and whether the company wants the commitment risk of long-term PPAs. This is where RE-led decarbonisation needs to be integrated into the MACC with realistic profiles rather than headline tariffs.

Process electrification comes next for many sectors, but the economics vary sharply by heat requirement. Low- and medium-temperature processes can become viable where electric boilers, heat pumps, induction systems or e-heaters are paired with lower-cost renewable power. High-temperature applications are more difficult and may require phased pilots. The MACC should therefore separate:

• Proven electrification measures with immediate economics
• Emerging options that depend on renewable power price declines or equipment redesign
• Demonstration projects needed to unlock later abatement

In some facilities, electrification may appear expensive today on a simple capex basis but becomes strategic when modeled against fuel price volatility, maintenance savings, local air-pollution co-benefits, and expected future carbon constraints.

Sequencing measures: a practical roadmap for 2026-2030

A common mistake is to implement projects in order of technology preference rather than system logic. The better approach is sequencing.

For most Indian industrial companies, a practical roadmap looks like this:

• Phase 1: Fix the baseline, standardise data, and capture no-regret efficiency
• Phase 2: Optimise grid and captive power strategy, then contract renewable supply
• Phase 3: Redesign thermal and electrical loads to enable electrification where viable
• Phase 4: Pilot hard-to-abate options such as renewable fuels, feedstock shifts or green hydrogen in selected use cases
• Phase 5: Address residual emissions through supply-chain action, product redesign and market mechanisms where relevant

This sequence matters because each step affects the next. For example, if efficiency reduces annual power demand by 8%, the renewable procurement volume and contract structure should be resized accordingly. If renewable power lowers the effective marginal power cost, then certain electric heat applications that looked uneconomic earlier may become viable. If process integration changes steam demand, boiler replacement decisions should be deferred until the future load shape is clearer.

A good roadmap also distinguishes between central and site-level ownership. Procurement can drive power sourcing, engineering can drive thermal redesign, finance can set hurdle rates and capital allocation rules, and sustainability can manage target integrity and external disclosures. Without this governance layer, the MACC remains a consulting deck rather than an execution plan.

This is why the most useful decarbonisation programmes combine Net-zero roadmaps & MACC with plant engineering and procurement advisory rather than treating target setting as a standalone exercise.

How to deal with hard-to-abate emissions and uncertain technologies

Not every tonne can be removed cheaply by 2030. Sectors with high-temperature heat, process emissions or reducing-agent dependence need a more selective approach.

In 2026, companies should avoid two extremes: assuming that all hard-to-abate emissions can be solved by future hydrogen, or dismissing those pathways entirely because current costs are high.

A more practical method is to classify hard-to-abate levers into three tiers.

• Tier 1: commercially deployable now in limited applications
• Tier 2: pilot-ready with selective economics or co-funding support
• Tier 3: monitor and prepare, but do not assume near-term scale

Green hydrogen, for instance, may make sense first in niches where grey hydrogen is already consumed, purity matters, and renewable electricity access is strong. It is much harder to justify in bulk heat replacement where delivered cost remains significantly above incumbent fuels. The right 2026 decision in many cases is not full conversion, but pilot design, infrastructure planning, and compatibility checks during current capex cycles.

Similarly, biomass and biogenic fuels may appear attractive on paper but require careful analysis of supply reliability, moisture content, storage risk, handling systems and sustainability claims. A MACC should not treat them as generic low-carbon fuel blocks without these constraints.

Linking the roadmap to finance, procurement and policy risk

A decarbonisation roadmap becomes board-ready only when it translates into capex, opex, returns and risk exposures. Management teams should therefore stress-test the MACC under multiple scenarios.

At minimum, use sensitivities for:

• Grid tariff escalation
• Open-access charges and banking assumptions by state
• Fuel price volatility
• Capacity utilisation changes
• Carbon price or compliance-cost proxy where relevant
• Export-market carbon exposure, including embedded-emissions scrutiny
• Cost of debt and internal hurdle rate changes

This is increasingly relevant for lenders and investors evaluating industrial capex. They are not only looking at emissions intent, but also whether the company has a credible pathway to reduce energy-cost volatility, maintain market access and avoid stranded high-carbon assets.

For exporters, there is also a strategic reason to build finance-grade abatement pathways now. Overseas buyers and regulators are scrutinising embedded emissions and data quality with more rigour. Even where there is no immediate direct carbon cost, weak emissions management can reduce competitiveness in procurement decisions.

Indian policy adds another layer. The emerging carbon-market architecture, energy-efficiency compliance, state open-access rules, and evolving standards for disclosure and assurance all influence project economics. A static decarbonisation plan prepared once and shelved is therefore of little use. The roadmap should be updated at least annually, with priority refreshes after major tariff changes, acquisitions, or production expansion.

What decision-makers should do in the next 90 days

For CXOs, sustainability heads, plant teams and lenders reviewing industrial decarbonisation opportunities in 2026, the next step is not to ask for a generic net-zero presentation. It is to ask for decision-grade analysis.

A practical 90-day agenda would be:

• Establish plant-level energy and emissions baselines across major sites
• Validate Scope 1 and Scope 2 factors, contracts and metering boundaries
• Identify the top 15-25 abatement levers by site and process
• Build a MACC with capex, opex, payback and tCO2e reduction estimates
• Define near-term and medium-term targets aligned to business growth plans
• Prioritise renewable procurement, efficiency and electrification measures that can move immediately
• Flag hard-to-abate emissions requiring pilots, partnerships or later-stage investment
• Create governance for implementation, MRV and annual refresh

Done properly, this approach gives management a realistic answer to four questions that matter: how much can be reduced, how fast, at what cost, and with what financing strategy.

That is the difference between a disclosure-led decarbonisation programme and an execution-led one.
