Green bonds are loans provided by an investor to a borrower which are used to fund projects or activities that promote climate change mitigation or adaptation or other environmental objectives. While the green bond definition can vary, this indicator includes bonds that are aligned with the four core components of the International Capital Market Association (ICMA) green bond principles or are certified by the Climate Bond Initiative (CBI). Issuers include corporates such as a company or financial corporation, and sovereign bond issuers which are national governments.
