All global gross domestic product depends, either directly or through supply chains, on nature: clean air and water, productive land and diverse and thriving flora and fauna. Every investment relies on nature. Business activities not only impact nature but also depend on it, making the degradation of nature a significant financial risk to investors’ portfolios.This toolkit was prepared by RIAA’s Nature Working Group, which is a collective of representatives from the Australian and Aotearoa New Zealand investment community. It serves as a primer for understanding nature-related risks and opportunities and supporting investors to analyse, engage and take action.The objective of the toolkit is to:-help investors identify nature-related risks and opportunities in their portfolios (assess);-help investors simplify this complex area, informing constructive conversations with stakeholders and companies about impacts and dependencies on nature (engage); and-unpack the suite of current and emerging tools and products to identify new investment opportunities (take action).
