Science-Based Targets and CBAM: Aligning Corporate Climate Goals

Key Takeaways

• Science-Based Targets (SBTs) provide a structured framework for carbon reduction that directly supports CBAM compliance requirements
• Indian steel exporters with validated SBTs demonstrate measurable commitment to decarbonization, potentially reducing CBAM certificate obligations
• The convergence of SBT methodologies and CBAM's carbon intensity calculations creates operational synergies for emissions monitoring
• Companies achieving 1.5°C-aligned targets show average emission reductions of 4.2% annually, exceeding CBAM's implicit decarbonization expectations
• Integration of SBT verification protocols with CBAM reporting systems reduces administrative burden by approximately 35%

Understanding Science-Based Targets Framework

Science-Based Targets represent emission reduction goals aligned with climate science requirements to limit global warming. The Science Based Targets initiative (SBTi) validates corporate targets against methodologies consistent with achieving net-zero emissions by 2050. For Indian steel exporters, SBTs provide a systematic approach to carbon management that directly interfaces with EU CBAM obligations under Regulation (EU) 2023/956.

The SBTi framework requires companies to establish near-term targets (5-10 years) and long-term targets (typically 2050) covering Scope 1, 2, and relevant Scope 3 emissions. Steel manufacturers must address process emissions from coking coal, electricity consumption, and upstream supply chain impacts. This comprehensive coverage aligns with CBAM's embedded emissions calculation requirements, creating natural synergies between target-setting and regulatory compliance.

Validation criteria demand targets achieve annual linear reduction rates of 4.2% for 1.5°C alignment or 2.5% for well-below-2°C pathways. These reduction trajectories exceed the implicit decarbonization rates embedded in CBAM's design, positioning SBT-committed companies advantageously for long-term compliance cost management.

CBAM Regulatory Framework Integration

The EU Carbon Border Adjustment Mechanism establishes carbon pricing for imports based on embedded emissions intensity. Steel products face CBAM obligations from October 2023 through transitional reporting, with financial obligations commencing January 2026. The mechanism requires detailed emissions reporting using installation-specific data or default values published by the European Commission.

CBAM's technical implementation relies on carbon intensity calculations expressed in tonnes CO2 equivalent per tonne of steel product. Default emission factors for Indian steel range from 2.3 to 2.8 tCO2e/tonne depending on production route and product specifications. Companies providing verified installation-specific data can demonstrate lower emissions intensities, reducing CBAM certificate requirements proportionally.

The regulatory framework under Regulation (EU) 2023/956 establishes monitoring, reporting, and verification (MRV) requirements that mirror established carbon accounting standards. This alignment enables companies with robust emissions management systems to leverage existing data collection processes for CBAM compliance, particularly when integrated with Science-Based Target monitoring protocols.

Operational Synergies Between SBTs and CBAM

The convergence of SBT methodologies and CBAM requirements creates significant operational efficiencies for steel exporters. Both frameworks demand granular emissions data collection, verification protocols, and annual reporting cycles. Companies implementing SBT-aligned monitoring systems develop the technical infrastructure necessary for CBAM compliance.

SBT validation requires third-party verification of emissions data and reduction progress, establishing credible measurement systems that satisfy CBAM's verification requirements. The GHG Protocol standards underlying SBT methodologies align with CBAM's emissions calculation approaches, enabling data system integration and reducing duplicative reporting efforts.

Scope 1 emissions monitoring for SBTs covers direct process emissions from steel production, matching CBAM's focus on installation-level emissions. Scope 2 electricity emissions tracking supports CBAM's indirect emissions calculations when applicable. This overlap eliminates redundant data collection and creates economies of scale in emissions management infrastructure.

Carbon Intensity Reduction Strategies

Steel manufacturers pursuing Science-Based Targets implement systematic decarbonization strategies that directly impact CBAM obligations. Process optimization, energy efficiency improvements, and fuel switching initiatives reduce embedded carbon intensity, decreasing CBAM certificate requirements over time.

Blast furnace optimization through improved burden preparation and process control can achieve 5-8% emission reductions without major capital investment. These improvements directly translate to lower CBAM obligations while supporting SBT achievement. Electric arc furnace operations benefit from increased scrap utilization and renewable electricity procurement, addressing both Scope 1 and Scope 2 emissions simultaneously.

Hydrogen-based direct reduction represents the most significant long-term decarbonization pathway for steel production. Companies with SBT commitments demonstrate credible transition planning toward low-carbon production technologies, potentially accessing preferential financing and carbon pricing mechanisms that offset CBAM compliance costs.

2025-2026 Regulatory Impact

The transition from CBAM's reporting-only phase to financial obligations in 2026 coincides with increasing corporate adoption of Science-Based Targets. Companies with validated SBTs enter this period with established emissions monitoring systems and demonstrated reduction trajectories, providing competitive advantages in compliance cost management.

Financial markets increasingly recognize SBT validation as a credible indicator of climate risk management. Steel exporters with validated targets access lower-cost financing for decarbonization investments, improving their ability to reduce carbon intensity and minimize CBAM obligations. This financial advantage compounds over time as carbon pricing mechanisms expand globally.

The European Commission's planned review of CBAM default emission factors in 2026 will likely reflect global decarbonization progress. Companies achieving SBT-aligned emission reductions position themselves favorably for potential adjustments to default values, while those without credible reduction plans face increasing compliance costs relative to industry benchmarks.

Implementation Roadmap for Steel Exporters

Indian steel exporters should initiate SBT development through comprehensive emissions inventory establishment covering all production facilities and supply chain impacts. This foundational step supports both SBT validation and CBAM compliance preparation. Baseline establishment requires 2-3 years of verified emissions data, emphasizing the importance of immediate action.

Target setting should align with sectoral decarbonization pathways published by the SBTi, incorporating steel-specific methodologies that account for process emissions and energy intensity factors. Near-term targets must demonstrate annual reduction rates consistent with 1.5°C or well-below-2°C scenarios, while long-term targets establish net-zero commitments by 2050.

Verification and validation processes require engagement with accredited third-party providers capable of assessing both SBT conformance and CBAM compliance systems. Integrated verification approaches reduce costs and timeline requirements while ensuring consistency across reporting frameworks.
