Commitment to the environment


IQE is committed to protecting both the local and global environments in which we operate. We will achieve this by ensuring that all our activities, including the provision of products and services, are conducted in an environmentally responsible manner.

IQE will ensure that: 

    • We fully integrate environmental considerations into the business planning and decision making processes.
    • Compliance obligations are identified and that our operations are conducted in accordance with these obligations.
    • We validate our fulfilment of compliance obligations by means of documented periodic review.
    • We employ best practice to reduce the environmental impact of our operations, prevent pollution, minimise waste and maximise the efficient use of energy and resources to protect the environment.
    • We continually improve our environmental management system and its performance by setting measurable objectives and reviewing them on a regular basis.
    • We provide suitable information and training to all employees, and interested parties to ensure that the aims of the environmental management system are achieved.

This policy sets the foundation upon which all IQE operations may expand to suit individual site requirements.
