Investment portfolio footprinting is the process of assessing the environmental impact of an investment portfolio. This involves analysing the environmental footprint associated with the companies and assets within the portfolio to understand their contribution to climate change and environmental degradation. While portfolio footprinting is most often applied to carbon emissions, at Osmosis we apply the same methodology to water consumption and waste generation. By measuring these environmental exposures, we can gauge the sustainability of our investments and calculate the savings in natural resource consumption of our portfolios.
