6.2 Green bonds and sustainable finance instruments

Green bonds are financial instruments that fund environmentally beneficial projects. They're part of a growing sustainable finance market that includes sustainability-linked bonds, social bonds, and blue bonds. These instruments aim to mobilize capital for sustainable development and climate change mitigation.

Green bonds share similarities with traditional bonds but have unique features. They require more extensive reporting on environmental impact and attract investors seeking both financial returns and positive environmental outcomes. The global green bond market has grown rapidly, driven by increasing climate change awareness and regulatory support.
