1. Green, Blue, Yellow & Sustainability-Linked Bonds (SLBs) vs Sovereign Green Bonds (SGrBs)
| Sustainable Bond Type | Regulatory Framework | Core Mechanism, Eligible Projects & Exam Traps |
|---|---|---|
| 1. Green Bonds & ‘Greenium’ | ICMA GBP & SEBI (NCS) Regulations | • 100% of proceeds are ring-fenced for environmental projects. • ‘Greenium’ (Green Premium): The yield discount (lower interest rate / lower yield to maturity) at which a Green Bond trades compared to a conventional bond of the same issuer. • Historical Firsts: Global 1st = EIB (2007) & World Bank (2008) | India 1st Corporate = Yes Bank (2015) | 1st Municipal Green Bond = Ghaziabad (2021) & Indore (2023 retail issue). |
| 2. SEBI’s Blue, Yellow & Transition Bonds (Feb 2023) | SEBI Green Debt Securities Framework | • Blue Bonds: For Water Management and the Marine/Ocean Sector (Blue Economy) (1st Sovereign Blue Bond globally: Seychelles, 2018). • Yellow Bonds: Specifically dedicated to SOLAR ENERGY generation and solar value chain. • Transition Bonds: For hard-to-abate sectors transitioning toward India’s NDCs. |
| 3. Sustainability-Linked Bonds (SLBs) | ICMA SLB Principles | Unlike Green Bonds, SLB proceeds can be used for GENERAL CORPORATE PURPOSES, while the bond’s coupon rate steps up/down based on whether the issuer achieves predefined KPIs and Sustainability Performance Targets (SPTs). |
| 4. India’s Sovereign Green Bonds (SGrBs) | MoF Framework (Nov 2022); Auctioned by RBI | • Governed by the Green Finance Working Committee (GFWC) chaired by the Chief Economic Adviser (CEA) (with CICERO as Second-Party Opinion provider). • STRICT EXCLUSIONS: Fossil fuels, NUCLEAR POWER generation, Hydropower plants LARGER than 25 MW, and landfill projects! • SLR & FAR Status: 100% eligible for Banks’ SLR and placed under the Fully Accessible Route (FAR) for FPIs. |
