Measuring the impact of MYTILINEOS' business activity on the natural environment is an ongoing process that is constantly evolving. The Company is committed to the stabilization and reduction of its environmental footprint, through the implementation of an integrated Environmental Management System certified in accordance with the ISO 1401/2015 international standard . The system is supported by individual environmental policies , targeted investments aimed at upgrading its production processes , by taking advantage of new developments in related technologies, and by applying the Best Available Techniques per Business Activity Sector . Environmental policy Core elements of MYTILINEOS' Environmental policy: • Adherence to the agreements and commitments that MYTILINEOS has undertaken over and above its statu- tory obligations. • Integration of Sustainable Development principles in the Company's decision-making and operation processes. • Assessment of the impacts of the Company's activities on the environment, identification and assessment of potential risks, adoption of the necessary precaution measures, and conduct of regular inspections and audits to confirm their implementa- tion and assess their efficiency. • Control and reduction of air emissions, in tandem with correct management and continuous reduction of solid and liquid waste, through using recovery, reuse and recycling techniques where feasible. • Responsible use of energy, water and other natural resources. • Protection of biodiversity and ecosystems. • Prevention of all identified pollution risks. • Readiness and effective response to emergency environmen- tal incidents and correction of all deviations by implementing corrective action plans. • Study, maintenance and evolution of appropriate prevention and suppression means, especially in cases where installa- tions are modified. • Correction of all confirmed deviations, by introducing and implementing improvement / restoration plans and preven- tive action plans. • Continuous briefing, training and awareness-raising activities for personnel per Business Activity Sector, adapted to the duties and needs of each employee in order to promote an environ- mentally responsible culture. • Acknowledgment of Social Partners' needs and expectations regarding environmental issues, demonstrating increased awareness of them and promoting a climate of cooperation. • Encouraging associates (contractors, suppliers, clients) to take action regarding environment-related issues and to enhance their environmental awareness. • Organization of regular internal and external audits to assess the performance of the Environmental Management System, the achievement of the targets set and the application of the relevant regulations and principles. In the context of the organization and monitoring of the Environmental Management system, the environmental manag- ers in each of Business Activity Sector of the Company, safeguard on a daily basis the proper environmental operation of all indus- trial units, while the CEO and the Executive Committee every 3 months, are getting informed and they evaluate the progress and performance on key environmental issues giving appropriate directions when required. 59 58
