During the production phase
it is important to ensure that environmentally sound production processes,
materials and chemicals are used. Other requirements related to
sustainability must also be fulfilled, for example occupational health and safety
demands. Additionally the supplier's environmental and social performance must
be considered since this is today seen as being a part of the companies'
responsibility. A commonly used tool for environmental assurance of production
activities is Environmental Management Systems (EMS)
according to ISO
14001 or EMAS.
