GSS bonds allow asset managers to direct their investments to specific projects and activities to achieve impact objectives.

  • Outlook for the GSS market, including implications of net zero emission pledges in Asia Pacific and COVID 19
  • Opportunities and challenges for investors, including how best to avoid “greenwashing” and balancing credit risk and impact considerations
  • Evolution of the GSS market, including regulatory developments and the rise of other ESG instruments such as sustainability-linked bonds.
