Green Finance Taxonomy and Nuclear Energy Expansion

Show this topic for:

Why in news

  • A NITI Aayog member recommended updating green finance classification rules to allow concessional capital flow into the nuclear energy sector.

What is the green finance framework context?

  • Green finance taxonomies classify sustainable investments to channel capital into low-carbon technologies.
  • Historically, sovereign green bonds and ESG frameworks focused primarily on renewable sources like solar and wind, omitting nuclear power due to radioactive waste concerns.

Key recommendations and proposed changes

  • Include nuclear power projects under eligible sectors for sovereign green bonds and sustainability-linked credit.
  • Provide long-term, low-cost capital access to support India's target of reaching 100 GW nuclear power capacity by 2047.
  • Develop specialized technical skills and local manufacturing infrastructure to lower capital expenditure for advanced reactor types.

Why it matters

  • Offers firm, non-intermittent baseline power necessary for balancing grid volatility caused by renewable energy integration.
  • Aligns Indian taxonomy with recent global shifts, such as the European Union's inclusion of nuclear power in its Sustainable Finance Taxonomy.

Key terms

Green Taxonomy

A statutory or regulatory classification system defining which investments and economic activities are environmentally sustainable.

Baseload Power

The minimum level of electric power required to continuously feed an electricity grid over a 24-hour period.

Prelims facts

  • Sovereign green bonds in India currently fund renewable energy, energy efficiency, and clean transportation.

Mains discussion

  • Role of nuclear energy as baseline power in achieving net-zero emissions by 2070.
