The Asian Infrastructure Investment Bank (AIIB) has published its very first Sustainability Report, offering a transparent look at its environmental disclosures and climate risk management. What makes this report particularly notable is AIIB’s decision to voluntarily adopt the newly released International Sustainability Standards Board (ISSB) framework, placing the bank among a small group of development finance institutions to take such a forward-looking step.

Embracing a New Standard for Climate Transparency

Released in 2024, the report applies the ISSB’s global baseline for sustainability-related disclosures. It outlines how climate risks are integrated across AIIB’s core functions, including governance, risk management, and strategic planning. As part of this disclosure, AIIB has for the first time reported on its financed emissions, offering insight into how its lending portfolio contributes to greenhouse gas outputs.

Climate Risk Deemed Non-Material to Financial Health

One of the report’s key conclusions is that climate-related financial risks currently do not pose a material threat to AIIB’s balance sheet or financial operations. This assessment suggests that the bank’s existing safeguards, project screening criteria, and risk oversight processes are successfully mitigating the potential financial disruptions posed by climate volatility.

Aligning With the Global Momentum from COP28

AIIB’s move to embrace the ISSB framework follows a collective promise made by multilateral development banks during COP28. The pledge encouraged the adoption of a consistent, science-based standard for climate disclosures. By taking early action, AIIB signals its readiness to contribute to the global push for harmonized, credible sustainability reporting across the financial system.

Leadership Statements Underscore Commitment to Accountability

Jin Liqun, President of AIIB, emphasized the significance of this development in supporting the bank’s mission to finance sustainable infrastructure. He noted that leadership in sustainable finance requires more than project investment it demands transparency, accountability, and a willingness to set the standard for others to follow.

Andrew Cross, AIIB’s Chief Financial Officer, further highlighted the value of the new disclosures. According to him, adopting the ISSB standards enables AIIB to improve stakeholder trust and demonstrate its long-term commitment to financial integrity and climate resilience. He described the effort as essential to reducing uncertainty in capital markets and building investor confidence.

ISSB Framework Bridges Development Finance and Climate Goals

By applying the ISSB’s transition relief mechanisms, AIIB is also acknowledging the challenges of adapting to a new reporting standard while taking meaningful steps toward full implementation. These measures allow institutions to phase in complex requirements without compromising the quality of information being shared with stakeholders.

Enhancing Confidence in a Low-Carbon Future

As the bank continues supporting infrastructure development across Asia and beyond, this move brings additional clarity to how it manages environmental risk. The report not only strengthens the bank’s internal practices but also reinforces the role that development finance can play in helping countries achieve net-zero goals.

By leading with transparency and aligning with emerging global norms, AIIB is taking a proactive role in shaping how multilateral financial institutions respond to the climate crisis. The report marks a foundational step in a broader journey that could influence sustainability reporting across the entire development finance sector.
