Retention time for environmental records

Answer:
ISO 14001 does not set any retention time. I use two criteria to establish retention times:

Follow the retention time defined by law or regulations when that is the case;
Follow a retention time of 4 years to ensure that all records from one certification cycle are kept during the cycle.

Remember, this is just my criteria.
