The green bond market is experiencing rapid growth, with $270 billion spent on green bond issuances in 2020. Green bonds differ from regular bonds in that the funds raised are exclusively used to finance projects with positive environmental impacts. Efforts are being made to prevent misleading marketing, known as greenwashing. The market for green bonds is expanding steadily, with annual issuance projected to reach $1.05 trillion in 2024. The US is one of the largest sources of green bonds, and corporations and governments alike are entering the market to finance green projects. Issuing green bonds offers advantages such as enhancing an issuer's reputation and accessing a broader investor base.
