Documenting significant environmental impacts

Answer:
ISO 14001:2015 according to clause 6.1.2 requires three kinds of documents:
* a list of the determined environmental aspects and impacts;
* an explanation of the criteria used by the organization to evaluate and distinguish significative environmental aspects and impacts; and
* a list of the significative environmental aspects and impacts after applying the criteria.

Many organizations use an environmental aspects and impacts register where they log all the determined environmental aspects and impacts, then they put in columns each of the criteria used to evaluate, and finally, they use a column to indicate if the aspect and impact are significative or not.
