What is Greenium?

July 25, 2024

The Chief Economic Advisor recently said that private investors need to "walk the talk" on prioritising sustainable investments, citing the low "greenium" from them on India's sovereign green bond offerings.

About Greenium:

  • Greenium, or green-premium, refers to the savings an issuer of a green bond realises on the associated coupon payment because the bond is green.
  • It is the amount by which the yield on the green bond is lower, compared with the conventional bond.
  • Green bonds are debt instruments that fund specific projects/activities categorised as 'green' under national or international green taxonomies.
    • Such activities may include renewable energy projects, electric buses, and energy efficiency initiatives. 
  • Each bond has an issuer, i.e., those who want to raise money with a promise of a regular fixed payment and investors, i.e. those who provide that money with a promise of a regular fixed income.
  • The logic behind a greenium is that because of the appeal of sustainability, green bonds attract investors who are ready to forgo some of their returns and accept lower payments (called a lower yield). 
  • Further, long-term green projects are associated with a reduction in both physical and financial risk. Thus, investors settle for lower returns, making green projects financially attractive for the issuers of these debt instruments.
