ISO 14001 Environmental Management lays down the criteria for a system which cares about the environmental management and releases certification to organizations which map out a framework of an effective environmental management system. This ISO 14001 Environmental Management framework can be made use by any industry dealing with any activity or sector. Any company using the ISO 14001:2015 can provide assurance to its stakeholders, management and to its employees that environment concern is a part of their business discussion and its impact is being constantly measured and improved upon. The ISO 14001 Environmental Management systems has been one of the most popular and used standard and has been revised very recently. It is a norm that all ISO standards are reviewed every five years so that it follows the modern trends and is not left behind. The changes that have been made are mainly in the increased importance of environmental management in the business strategy of any institute and should be a part of its process; leadership to implement it is stressed upon; more proactive initiatives are added to protect the environment from further deterioration by use of sustainable resources and reducing effects of climatic changes; improved environmental performance is added; better communication strategy with considerable importance to life cycle thinking. A three-year transition period is allowed to the companies to adopt the revised format, to migrate their environmental management system to the new edition of the standard. After this if the companies want a third party certification, they will have to seek certification to the new version of the standard. The former version, ISO 14001:2004, and any certification to it, will be null and void.
