India Climate Budget 2026–27: Ambition Rises, Spending Remains Measured

Climate Concerns Gain Visibility, But Caution Persists

India’s Union Budgets have gradually begun reflecting climate priorities since 2021, when a modest allocation of Rs 4,500 crore was earmarked to localise solar photovoltaic manufacturing and reduce dependence on imports. In the Union Budget 2026–27 , climate-linked spending has widened in scope, touching sectors such as heavy industry, renewable energy, green hydrogen and nuclear power. Yet, the overall approach remains cautious, with allocations signalling pilots and gradual scaling rather than rapid transformation.

Carbon Capture Push Signals Experimental Phase

The most prominent announcement is a proposed ₹20,000 crore outlay over five years for Carbon Capture, Utilisation and Storage (CCUS) . While this marks India’s formal entry into CCUS deployment, the funding level indicates an emphasis on pilot projects and demonstrations rather than full-scale industrial rollout.

Globally, CCUS facilities exist in countries like Norway, Canada and the United States, but costs remain high and scalability uncertain. For India, the technology is especially relevant for sectors such as steel, cement and aluminium, where emissions are structurally embedded. With the European Union’s Carbon Border Adjustment Mechanism set to impose carbon-linked costs on imports, decarbonisation has become not just an environmental priority but a trade competitiveness issue.

Renewables: Rooftop Solar and Irrigation Pumps

The Budget significantly enhances support for decentralised solar energy. The PM Surya Ghar Muft Bijli Yojana sees allocations rise to ₹22,000 crore in 2026–27 , up from ₹17,000 crore (RE) in the previous year. Rooftop solar offers multiple benefits—lower transmission losses, reduced land pressure and direct savings for households—but execution challenges remain, including distribution company cooperation and access to upfront finance.

Similarly, funding for PM-KUSUM , which promotes solar-powered irrigation pumps, has been maintained at Rs 5,000 crore . Revised estimates suggest stronger-than-expected uptake, reflecting growing farmer interest in energy-efficient irrigation solutions.

Nuclear and Green Hydrogen: Structural Constraints

On nuclear energy, the government has extended zero basic customs duty on nuclear plant equipment imports until 2035 , lowering capital costs. However, nuclear power continues to face long gestation periods, financing risks and concerns related to safety and liability. Although recent legal changes allow private participation, investor appetite remains uncertain in a sector closely tied to national security.

Green hydrogen remains another area where ambition exceeds expenditure. Despite policy support and strategic intent, actual budgetary utilisation has been modest, underlining persistent gaps between announcement and implementation.

Important Facts for Exams

• India introduced climate-linked budgetary measures more prominently after 2021

• ₹20,000 crore over five years allocated for CCUS in Budget 2026–27

• PM Surya Ghar rooftop solar allocation raised to Rs22,000 crore

• PM-KUSUM allocation sustained at Rs5,000 crore

• EU’s CBAM links industrial decarbonisation with export competitiveness

Overall Assessment: Intent Strong, Scale Limited

India’s climate budget for 2026–27 reflects a familiar pattern—clear recognition of climate risks and sectoral priorities, but restrained fiscal commitment. While
