Overview
The UNEP has warned that the world may cross the 1.5°C warming limit in the next few years. This pushes all countries, including India, to speed up decarbonisation. At the same time, India must still build most of the housing, factories, power lines and urban infrastructure needed for its next phase of growth.
Key Developments
- Building stock: NITI Aayog estimates that 86% of the floor space that will exist in 2070 is yet to be built. Total floor area will rise from ~18 billion m² in 2020 to **42 billion m² by 2070**.
- Steel & cement: Crude‑steel capacity is projected to grow from **200 million tonnes (2024‑25)** to **300 million tonnes by 2030‑31**. Cement output is expected to increase from **427 million tonnes (2024)** to **660 million tonnes by 2030**.
- Power transmission: The IEA says transmission bottlenecks have already held back about **60 GW** of renewable capacity.
- Regulatory progress: The ECBC 2017 is notified in 27 states, legally incorporated in 21. New codes — ECSBC 2024 for commercial buildings and Eco‑Niwas Samhita (ENS) 2024 for homes — have been released.
Important Facts
Unlike mature economies where about 80% of the 2050 building stock already exists, India can embed efficiency from the start. The gap is not technical knowledge but implementation. Embedding ECBC and the newer codes into building permits, occupancy certificates and grid‑connection approvals can force compliance.
In the power sector, the Ministry of Power plans **590 GW** of new generation between 2023‑2032. Without parallel transmission and storage expansion, the clean‑energy gains will be limited. Similarly, low‑carbon steel and cement face technology gaps: hydrogen‑based steel is not yet viable, and large‑scale carbon capture in cement is farther down the road.
Public procurement offers a lever. Agencies such as Indian Railways and the National Highways Authority can set emission‑intensity thresholds in tenders, using the existing green‑steel taxonomy. Competitive bidding would reveal the green premium and encourage producers to innovate.
Financing remains a hurdle. The IEA notes that India’s cost of capital for grid‑scale renewables is about **80% higher** than in advanced economies. Targeted instruments like payment‑security mechanisms, partial credit guarantees or concessional debt can lower the risk, but they also shift exposure to the public balance sheet.
Exam Relevance
This article touches on several GS‑3 themes: climate change mitigation, energy security, infrastructure planning, and industrial policy. Understanding the role of CCTS and green‑steel taxonomy helps answer questions on market‑based climate tools. The contrast between India’s “choice‑driven” infrastructure and the “legacy‑driven” stock of developed economies is useful for comparative analysis in essay questions.
Way Forward
- Mandate the new building codes (ECSBC 2024 and ENS 2024) in all state‑level permits and link non‑compliance to higher connection charges.
- Accelerate transmission planning to match the projected **590 GW** generation addition, including investment in grid‑scale storage.
- Use public procurement to set clear emission‑intensity thresholds, leveraging the green‑steel taxonomy and aligning with CCTS targets.
- Introduce targeted financing tools (partial guarantees, concessional loans) for proven low‑carbon projects while keeping a strict risk‑assessment framework.
- Promote flexibility in sectors where technology is still evolving, ensuring future upgrades can be accommodated without costly retrofits.
By making the right choices now, India can avoid stranded assets, reduce future correction costs, and stay on a credible path to meet its climate commitments.
