Environment 2025-26 Capstone for UPSC: Policy Shifts, Key Numbers, CCUS and Infrastructure versus Disaster Risk
How the Capstone Helps
🎯 Exam priority: Tier-2 capstone. Use this as a last-mile revision map after the earlier articles. UPSC 2025 and 2026 Mains asked: what Carbon Capture, Utilization and Storage (CCUS) is and its role in tackling climate change (2025); how to manage the contradiction between rapid infrastructure development and disaster-risk reduction in ecologically sensitive areas (2026); and India's energy security (2026). The Prelims 2026 paper also asked about the Andaman and Nicobar Islands' tropical climate and rainfall pattern.
The year's story in one line: India is moving environmental regulation from case-by-case permissions towards producer responsibility, trust-based compliance, digital clearance and market instruments, while pushing non-fossil power, storage, hydrogen and CCUS.

Two Mains Frames and What to Re-check
Two Mains frames to master
1. Carbon Capture, Utilisation and Storage (CCUS)
What it is: capturing CO2 from industrial or power-plant flue gas (or directly from air), using it as a raw material (for example in chemicals or building materials) or storing it permanently underground. Why it matters: some emissions, such as cement process emissions and parts of steel, cannot be removed by electrification alone, so capture is the way to reach net zero in 'hard-to-abate' sectors. India's push: a CCUS roadmap was launched in December 2025 and Budget 2026-27 proposed ₹20,000 crore over five years for CCUS in power, steel, cement, refineries and chemicals; CCUS is one of the sectors approved for the voluntary offset mechanism of the carbon market. Limits: high cost and energy use, storage-site and monitoring needs, and the risk of prolonging fossil use.
2. Infrastructure versus disaster-risk reduction in ecologically sensitive areas
Fragile terrain such as the Himalaya needs roads, hydropower and tunnels for connectivity and security, but unplanned works add to landslides, flash floods and glacial lake outburst floods. A balanced answer uses carrying-capacity and hazard mapping before approval, strict ESZ and EIA compliance with cumulative-impact assessment, slope and drainage engineering, and early warning. The Economic Survey notes that disaster financing has moved beyond relief to prevention through the State and National Disaster Mitigation Funds, and that a programme to monitor glaciers and glacial lakes in the Indian Himalayan region has been approved under the National Disaster Mitigation Fund.
