Advantages 
ISO 14001 was developed primarily to assist companies’ in reducing their environmental impact, but in addition to an improvement in environmental standards and performance, organisations can reap a number of economic benefits including higher conformance with legislative and regulatory requirements by utilizing the ISO standard. 
Firstly by minimizing the risk of regulatory and environmental liability fines and improving an organization's efficiency, leading to a reduction in waste and consumption of resources, operating costs can be reduced. 
Secondly, as an internationally recognized standard, businesses’ operating in multiple locations across the globe can register as ISO 14001 compliant, eliminating the need for multiple registrations or certifications. Thirdly there has been a push in the last decade by consumers, for companies to adopt stricter environmental regulations, making the incorporation of ISO 14001 a greater necessity for the long term viability of businesses and providing them with a competitive advantage against companies that do not adopt the standard. This in turn can have a positive impact on a company’s asset value  and can lead to improved public perceptions of the business, placing them in a better position to operate in the international marketplace. Finally it can serve to reduce trade barriers between registered businesses.
