About Accrona
Your strategic partner for meaningful impact
At Accrona, we are more than just advisors—we are your partners in navigating the evolving world of sustainability. Our global team brings together pioneers who have shaped sustainable finance from its earliest days - from developing groundbreaking methodologies now used by leading institutions to building and operating pioneering companies to executing over 150 successful sustainable finance transactions across continents.
The name "Accrona" embodies our purpose—uniting sustainability and finance. It combines "Akka," the Nordic goddess of fertility and future generations, representing sustainability's mission to meet the needs of the present without compromising future generations. We paired this with "krona," the Nordic currency, reflecting the region's global leadership in sustainable finance. This fusion in our name reflects our commitment to approaching sustainability from a financial and value-generating mindset.
