As the largest ever infrastructure programme, the Belt and Road Initiative (BRI) will reshape development for the coming decades. The finance sector and other actors have a tremendous opportunity to contribute to sustainable development and environmental protection by mitigating negative environmental impacts of infrastructure and investing in natural capital. However, significant action by all stakeholders will be required to ensure the BRI delivers sustainable outcomes. The finance sector can play a key role in delivering sustainable infrastructure by requiring best practices in infrastructure planning, design, construction, and operation. WWF is keen to support financial institutions in this journey.
