The world's infrastructure gap is currently estimated to be an astronomical US$ 90 trillion by 2030. Recognizing this shortfall of resources will be particularly significant in emerging markets, governments of the BRICS countries decided in 2015 to create their own financial institution, the New Development Bank (NDB). The NDB's aspiration to meet the vast and unfulfilled infrastructure requirements of its member countries, whilst retaining a deliberate focus on sustainable development, represents a bold departure from approaches currently followed by its counterpart institutions. The NDB's efforts to promote what it broadly labels as 'sustainable infrastructure' is thus both welcome and laudable.
