The Asian Infrastructure Investment Bank (AIIB) finances Infrastructure for Tomorrow, with sustainability at its core. Since beginning operations in 2016, AIIB has invested in infrastructure designed to improve lives, strengthen communities and support economic development across Asia and beyond.
The Sustainable Development Bonds Impact Report 2025 connects the capital AIIB raises in global markets with the sustainable infrastructure portfolio it finances. Through portfolio- and project-level reporting, it provides investors and other stakeholders with transparent information on the environmental and social outcomes associated with AIIB financing.
Introduced in April 2021, AIIB’s Sustainable Development Bond Framework sets out the criteria for project selection and the strategies, policies and processes underpinning the program. As some of AIIB’s earliest projects reach completion, evidence of their impact is becoming clearer.
This year’s report strengthens AIIB’s reporting by presenting achieved results from selected completed projects and those further advanced in implementation alongside expected outcomes from newer investments.
AIIB regularly reviews and enhances the Sustainable Development Bond Framework and Impact Report to reflect industry best practices, market expectations, evolving sustainable finance and development trends and changes in AIIB’s strategies, policies and processes.
AIIB welcomes feedback from investors, stakeholders and market participants. Please email comments to funding@aiib.org.
 
AIIB’s Sustainable Development Bonds represent a commitment to financing projects that prioritize environmental and social sustainability. Through the issuance of Sustainable Development Bonds, AIIB channels funds into projects in areas such as renewable energy, clean transportation, and climate adaptation, assisting clients in their efforts to achieve the United Nations Sustainable Development Goals (SDGs).
In 2025, AIIB accomplished its largest joint borrowing program, funding USD10.2 billion, including nine benchmark transactions in seven currencies. For the first time in a calendar year, AIIB issued three USD SEC benchmark bonds across the curve, all of which attracted significant demand, reflecting the desirability of high-quality liquid assets with proceeds that fund sustainability. One highlight of the year was issuing the inaugural public HKD benchmark, the first public‑format HKD bond issued by an international issuer, settling locally in the Central Moneymarkets Unit. The HKD transaction marks a milestone for the opening of the public HKD market to international issuers and expands the suite of sustainable development bonds in this market.
Building on the experience gained during the pandemic, AIIB’s Board of Directors approved the Bank’s Health Strategy in December 2024 to support Members’ health priorities and help advance universal health coverage (UHC). The strategy addresses megatrends such as climate change, demographic shifts, urbanization, technological innovation, and health security risks.
AIIB published its flagship report, Asian Infrastructure Finance 2025: Infrastructure for Planetary Health, which underscores the intricate interconnections between climate change, environmental degradation, biodiversity loss, and human health, presenting a compelling case for adopting a “planetary health” paradigm to address these global challenges.
AIIB, in its pursuit of fostering sustainable development, places investment in health infrastructure as a key area of support for its Members. This underscores the Bank’s commitment to social development and inclusion.
AIIB supports its Members’ efforts to achieve the ambitions of the SDGs adopted by the United Nations in 2015. The Bank serves as a key partner for advancing the 2030 Agenda for Sustainable Development through its financing and investment activities.
