EY has a longstanding tradition of sustainability consultancy, for almost 20 years, the company has been providing sustainability audit and consulting services and assisting clients with sustainable transformation. In 2021, the sustainability consulting portfolio significantly expanded to include additional services such as strategy, tax, M&A, and financing, as well as the implementation of EU taxonomy, CSRD or CSDDD regulations. Since then, core sustainability consulting has been even more closely integrated with all other service lines, from tax, management consulting through to strategy and transactions, thus bringing these activities together under the umbrella of the EY Sustainability initiative.
