Why This Role Matters

Sustainability reporting is rapidly moving from voluntary corporate disclosure toward regulated, assured information that increasingly sits alongside financial reporting.

This role places you directly within that transition, combining ESG assurance, sustainability reporting, GHG emissions, climate risk, CSRD, ISSB, EU Taxonomy, and non-financial data assurance.

For an accounting or assurance professional looking to build a serious career in sustainability, it offers a strong bridge between traditional financial assurance and the emerging sustainability reporting ecosystem.
