The latest Intergovernmental Panel on Climate Change report, Global Warming of 1.5 ºC, notes the importance of mobilizing green finance for limiting global warming to 1.5 degrees Celsius and preventing catastrophic climate change. In line with this, some countries have been implementing policies to support green bonds. Green bonds are debt securities whose proceeds are used to fund environmental projects, including climate change mitigation and adaptation. Therefore, unlike conventional bonds, green bonds finance projects with clear environmental benefits (ICMA 2018).
