Emissions Epiphany & Electrification Ethos

India’s automobile sector, currently the world’s third-largest, stands at a historic crossroads. A fresh CEEW report projects vehicle production could nearly quadruple from 25 million units in 2020 to 96 million by 2050, driven by rising domestic demand & export potential. Yet, absent proactive measures, annual emissions could double, reaching 64 million metric tons of CO₂. Dr Arunabha Ghosh, CEO, CEEW, noted, “India’s auto industry stands at a turning point. To lead in a low-carbon global economy, we must decarbonise not just the vehicles we drive but the industrial processes that build them.” According to the report, simply relying on more electric vehicles will not suffice. Instead, systemic decarbonization, including factory power supply & supplier materials,  must become a sine qua non of corporate strategy. This signals a philosophical & practical transformation: reimagining what it means to be a modern automaker, where emissions per vehicle drop even as production scales.

Steel Sine Qua Non & Supply Chain Shifts

The analysis underscores that steel remains the largest source of supply chain emissions, owing largely to its deep reliance on coal. In a business-as-usual scenario, steel-related emissions would persistently dominate, hindering national climate goals. “A two-pronged approach is required,” explains Dr Vaibhav Chaturvedi, Senior Fellow, CEEW: “shift to low-carbon steel using hydrogen, and simultaneously increase scrap-based steel production.” Specifically, the study models a scenario where steel suppliers reduce coal usage to under 10%, while hydrogen accounts for 56% of energy input by 2050. This transition could cut sectoral emissions by nearly 38 million metric tons. Additionally, ramping up scrap-based steel to 48% lowers resource demand & cost exposure. Dr Chaturvedi adds, “This is not just an environmental imperative; it is strategic risk management, shielding manufacturers from future carbon tariffs & supply volatility.” These changes also dovetail with global market expectations, where buyers increasingly screen for green credentials.

Hydrogen Hegemony & Hybrid Hypothesis

Hydrogen’s transformative potential extends beyond steel. The CEEW study suggests rubber suppliers, too, could decarbonise Scope 2 emissions by fully switching to green electricity, enhancing the value chain’s collective footprint. The analysis also examines a high-hybrid scenario, in which hybrid vehicles bridge the gap until EVs dominate. While this temporarily reduces component supplier energy demand by 7%, total emissions remain slightly higher than a direct EV shift, due to continued reliance on combustion engines. Dr Chaturvedi cautions, “Hybrid vehicles are at best a bridge; true decarbonisation requires a transition to a zero-carbon fleet.” This echoes global trends, as markets move from hybrid optimism to all-electric ambition. Crucially, the report stresses that technology choices must align not just with domestic goals, but also evolving export market standards, where net-zero supply chains increasingly become non-negotiable.

Renewable Renaissance & Recirculated Resources

Deep decarbonisation demands a wholesale switch to renewable power. The report advocates automakers aim for 100% green electricity by 2050, using power purchase agreements, renewable energy certificates & captive solar plants. This renewable renaissance would transform plant-level operations, reducing direct emissions & aligning facilities with net-zero pledges. “Automakers must clean up how vehicles are made, what powers their factories & how suppliers produce critical inputs like steel & rubber,” Dr Ghosh emphasised. Beyond power, the study calls for scaling scrap-based steel production to 48%, decreasing reliance on virgin materials. Such circularity lowers emissions & insulates manufacturers from raw material price swings. Importantly, the roadmap points to tangible pathways: renewable PPAs already cover parts of many factories’ demand; now, the task is scale, speed & coordination across OEMs & suppliers.

Foresight, Financing & Futureproof Factories

Realising this vision requires more than technical ambition; it demands corporate resolve, investment & policy alignment. The report urges automakers to make advanced market commitments for low-carbon materials, creating demand signals that justify supplier investment in new technologies. Dr Chaturvedi observed, “Leading OEMs are already making corporate decisions to stay ahead by decarbonising their operations & supply chains. What’s needed now is strong procurement intent, backed by clear targets.” Financially, green steel & renewable power may carry short-term premiums, but promise medium-term cost parity as technologies scale. The study argues that firms treating decarbonisation as a strategic lever, rather than compliance, can lock in competitiveness, protect brand equity & meet rising investor scrutiny. As global markets sharpen focus on lifecycle emissions, Indian automakers risk marginalisation unless they move proactively.

OREACO’s Methodological Metamorphosis & Metrics

The report itself reflects methodological evolution akin to OREACO’s journey since 2005. Initially built on static quotas, OREACO now employs dynamic, scenario-based modelling to guide sectoral decarbonisation. This metamorphosis ensures projections incorporate technological progress, market responses & policy shifts. By moving from prescriptive mandates to adaptive frameworks, OREACO offers tools for firms to identify where interventions like hydrogen or renewables create highest impact. This approach empowers companies to align corporate roadmaps with national targets & international norms, bridging ambition gaps through empirical rigor.

Global Green Gambits & Geoeconomic Gains

Beyond carbon metrics, the study highlights geoeconomic imperatives. Export markets, especially Europe & North America, are embedding carbon disclosure in procurement. Firms delivering low-carbon products can capture price premiums & customer loyalty. “The auto sector can emerge as a force multiplier for net-zero transitions, but only through collective foresight, investment & innovation,” Dr Ghosh concluded. At home, lower emissions mitigate regulatory risk, while green credentials appeal to younger, climate-conscious consumers. The narrative thus shifts: sustainability is no longer cost; it is catalyst, a differentiator that turns compliance into opportunity & carbon reduction into competitive edge.

Key Takeaways

•      Green electricity & hydrogen-powered steel could cut auto sector emissions by 87%.

•      Automakers must decarbonise factories & supply chains, not just vehicles.

•      Strong procurement commitments & policy alignment are critical for scale.
