The INTOSAI Working Group on Environmental Auditing (WGEA), established in 1992, aims to increase the expertise in environmental auditing and to enhance environmental governance with high-quality contribution and visibility by both members of the Working Group and non–member SAIs. Currently the INTOSAI WGEA consists of 86 member SAIs being the largest working group under the auspices of the International Organization of Supreme Audit Institutions (INTOSAI). Also, six INTOSAI regions namely AFROSAI, ARABOSAI, ASOSAI, EUROSAI, OLACEFS, and PASAI have established a Regional Working Group on Environmental Auditing (RWGEA).
