Established in 2021, Celsia’s software streamlines regulatory sustainability reporting, particularly addressing the European Union’s (EU’s) Corporate Sustainability Reporting Directive (CSRD) regulations. By automating CSRD reporting workflows and providing expert guidance, Celsia supports over 300 companies in meeting sustainability reporting requirements efficiently, with some clients experiencing up to an 80% reduction in reporting time compared to traditional methods.
