The era of voluntary sustainability reporting is ending. Mandatory disclosure requirements from the U.S. Securities and Exchange Commission, the European Union's Corporate Sustainability Reporting Directive, and the International Sustainability Standards Board are creating a new compliance landscape that will affect virtually every publicly traded and large private industrial company. This 44-page guide, produced in partnership with GreenPath Consulting, provides a clear roadmap for understanding these requirements, assessing organizational readiness, and building the data systems, governance structures, and internal capabilities needed for compliance. The guide maps the overlapping and divergent requirements of the three major frameworks, identifies the 43 specific data points that companies in the industrial sector will need to collect and report, and provides a realistic timeline for implementation.
