Climate change poses one of the greatest threats to human health to date - particularly in Low- and Middle-Income Countries (LMICs), where its impacts will be felt most acutely, and adaptation capacities remain severely limited. Previous research has highlighted the potential role of insurers and adjacent actors in supporting climate adaptation and strengthening resilience. However, the role of health insurance value creation has largely been overlooked. This report aims to help fill that gap by focusing on the potential of digital platform providers (Insurtech platforms) to improve access to insurance - and thereby unlock scaling potential for a range of interventions across the insurance value chain that support both individual and health system resilience in LMICs. It focuses specifically on impact investing as a financing channel to enhance the reach and effectiveness of these platforms across three key dimensions: affordability, literacy, and distribution of insurance products - all of which are key to improving insurance access. The report provides insights into the strategies these platforms use to address these challenges guided by a Theory of Change perspective drawing on expert interviews and desk research. The key findings are a number of best practices that impact investors could look out for to achieve both impact and Return on Invest.
