DIN 7991, a German standard published in 2009, outlines the requirements for the auditing of environmental management systems. This standard provides a systematic approach to evaluating the environmental performance of an organization, ensuring that its environmental management system (EMS) is effective in minimizing its ecological footprint. By implementing DIN 7991, organizations can demonstrate their commitment to environmental sustainability, identify areas for improvement, and ensure compliance with relevant environmental regulations. The standard's guidelines for auditing EMS enable organizations to assess their environmental performance, identify opportunities for reduction of waste and pollution, and continually improve their environmental management practices.
