Our aim is to transform finance to make sustainable business, business as usual. Accounting for Sustainability (A4S) was established by HM King Charles III in 2004, when he was The Prince of Wales, “to help ensure that we are not battling to meet 21st century challenges with, at best, 20th century decision making and reporting systems.” A4S aims to inspire action by finance leaders to drive a fundamental shift towards resilient business models and a sustainable economy.
