The Bank for International Settlements Innovation Hub published outputs from Project Symbiosis, a collaboration between its Hong Kong Centre and the Hong Kong Monetary Authority, on using artificial intelligence and big data to help companies track and disclose the environmental impacts of their own activities and those of their suppliers. The project applied targeted, simplified AI methodologies to reduce information gaps related to climate and nature risks in supply chains, and found that these approaches can improve the speed, breadth and quality of data collection. It also demonstrated how environmental impact results can be generated in a way that remains flexible across different data availability scenarios, while highlighting potentially financeable emission-reduction opportunities. While the work was applied in the context of Scope 3 reporting, the published materials cover key findings, a technical report and an applied example, and point to wider potential use cases including risk assessment, supply chain management and reporting automation.
