Reconciling the infrastructure needs of Viksit Bharat 2047 with net-zero 2070 is India's central climate dilemma. Discuss.

India must build the housing, transport and urban networks of a developed nation by 2047. It must also reach net-zero by 2070. NITI Aayog's scenario studies try to fit both goals into one pathway [3]. Construction runs on carbon-heavy cement and steel, so the tension is real, but it can be managed.

Why it is a dilemma

• Demand surge: NITI's cement roadmap projects output rising from about 430 Mt now to about 1.75 billion tonnes by 2047 [1]. Even if each tonne emits less, total emissions can still rise.
• Process emissions: more than half of cement emissions come from limestone calcination, the chemical reaction that releases CO₂. Clean electricity cannot remove these [1].
• Steep pathway: emissions per tonne must fall from 0.63 to about 0.09–0.13 tCO₂e by 2070, a cut of roughly 80–85% [1].
• Lock-in: kilns and blast furnaces built today will still be running in 2070, so today's choices fix future emissions.

Why it is central, and its limits

• Finance: net-zero needs about $22.7 trillion by 2070. Annual climate finance must rise from about $135 billion to about $450 billion [2].
• Trade: the EU's CBAM has been fully operational since 1 January 2026 and covers cement, steel and aluminium [5]. Delay now carries an export cost.
• However, NITI projects GDP of about $30 trillion by 2047 even under net-zero scenarios [2]. This suggests a trade-off to be managed, not a choice between growth and climate.

Reconciling the two

• Carbon pricing: cement was among the first four sectors to get GEI targets under the CCTS in October 2025, and the scheme now covers 490 entities [4]. Targets should tighten on a published schedule.
• Material efficiency: use more clinker substitutes such as fly ash, slag and LC3 (BIS standard IS 18189:2023). Use refuse-derived fuel made from municipal waste [1].
• CCUS and blended finance: fund pilot carbon-capture plants with public money to bring down their cost [1][2].
• Green public procurement: CPWD and state PWD tenders should accept blended cement to create early demand.

In short, the conflict lies less in the goals than in how fast policy moves. If India uses carbon pricing, material innovation and planned finance now, its new infrastructure need not lock in emissions. This would serve SDGs 9 and 13 and India's Panchamrit pledge, so that Viksit Bharat is also a low-carbon Bharat.
