ISO 14001 considers the environmental implications of each stage of a service or product. Implementing this global standard helps an organisation to comply with increasingly stringent environmental laws and regulations. The ISO regularly reviews and revises its standards to ensure that their certifications are current and relevant. The current standard, ISO 14001:2015, combines relevance to environmental management of a business with ISO 9001 (the International Standard for Quality Management Systems). Once in place, the organisation must undergo an annual audit in order to maintain their certification.
