To incorporate natural capital into national green growth planning, it is critical for decision-makers to have access to information that reflects the quality, quantity and spatial configuration of natural capital assets. The utility of natural capital analysis for policy-making is ultimately dependent on the availability of information, which can be provided through data platforms and tools. This working paper aims to bridge the knowledge gap around accessible data on global natural capital assets. To do so, the paper assesses 28 platforms and tools based on their potential to provide access, manipulate and visualize natural capital data. The paper also identifies some limitations on the utility of available platforms and tools and recommendations to address them.
