Singapore has updated its green bond framework to include new economic activities that can be financed with green bonds issued by the government, aligning it with the Singapore-Asia Taxonomy and latest market standards. Water and air transport infrastructure, such as hydrogen-based refuelling, can now be financed through these instruments. The revisions ensure that projects funded by public-sector green bonds will significantly contribute to Singapore's climate goals. The framework also provides detailed thresholds for emissions-intensity in activities like electricity generation using hydrogen. Furthermore, DNV has confirmed that the updated framework complies with ICMA's green bond principles and Asean Capital Markets Forum standards, enhancing the credibility and alignment of Singapore's green bond initiatives.
