Here is our pick of the 3 most important XBRL news stories from the last week. 

1  Workiva simplifies and accelerates ESG reporting for companies across the globe

Workiva Inc. (NYSE:WK) announced it has extended its cloud platform capabilities to help companies meet the rapidly changing landscape of Environmental, Social and Governance (ESG) reporting with a fit-for-purpose ESG solution. The end-to-end solution allows businesses to keep pace with the demand from regulators, ratings agencies, institutional investors and other stakeholders for trusted, transparent data and proof of ESG forward-looking business goals.

Mandatory, standardised, audited ESG reporting prepared within a strict control framework and delivered as XBRL structured data – that’s what mainstreamed sustainability reporting will have to look like going forward. Now that Workiva offers an ESG reporting package, it’s time to show off its capabilities by starting its own ESG reporting. Note that the author has a commercial interest in the firm.
