Now that your quality management system is certified to ISO 9001, you can use your quality management knowledge to improve other areas of your organization – such as environmental management. ISO 14001 is the standard for environmental management and it follows many of the same requirements as ISO 9001. That means you’ve already completed nearly half the work needed to certify to ISO 14001 as well.
And if you already have two or more systems in place, you can combine and streamline the way you manage processes. This makes them more manageable and eliminates the need to duplicate work. You can also try using PAS 99 as a framework to integrate systems to boost all-round performance.
