With respect to the environment, our approach follows the precautionary principle2 which states: “Where there are threats of serious or irreversible damage, lack of full scientific certainty shall not be used as a reason for postponing cost-effective measures to prevent environmental degradation”. We strive to operate in a manner that protects the health and safety of all of the people with whom we work. We also strive to be an employer of choice by providing a working environment in which all employees are treated fairly and with respect so that they can realise their full potential.
