Energy & Air emissions

Sustainable development challenges

The Company's electric power generation and aluminium production activities are the primary sources of its energy consumption and carbon dioxide (CO2) emissions, which contribute to climate change, and which constitute a significant operating cost. The commitment to gradually reduce its carbon footprint is one of the Company's most important challenges under its new Sustainable Development strategy.


Responsible use of energy and other natural resources, in accordance with the main axes of the MYTILINEOS Environmental policy. Achievement of the ambitious targets of reducing CO2 emissions by 30% and a net-zero carbon footprint by 2030 and 2050 respectively.

Major risks

  • Any deviations from the applicable legislation on industrial emissions may cause additional atmospheric pollution and result in increased costs due to the need of purchasing additional CO2 emission allowances, affecting the Company's financial results as well as its capacity to retain its existing or attract new customers, investors or business partners.
  • A further increase in the price of CO2 emission allowances (€/t), as this may be shaped by the future EU policies on energy and climate, is likely to affect future compliance costs.

Management / control practices

  • MYTILINEOS has adopted specific initiatives to tackle climate change, which are outlined in the "Tackling climate change" section of this report. The Company's CO2 emissions targets (Scope 1 and 2) are aligned with the emissions reductions required to keep global warming below 2°C by 2030, in line with the vision of the European Green Deal to achieve climate neutrality by 2050 as well as with the Global Sustainable Development Goals. By 2026, MYTILINEOS aspires to complete its investment program of 1.5GW in renewable energy sources in Greece, to have made significant progress in the electrification of the Metallurgy Sector from RES, to have increased the production of secondary aluminum to 26% of total production aluminum and to have incorporated digital industrial methods in the production stages. Meanwhile, MYTILINEOS proceeds with the implementation of relevant initiatives such as the use of electric vehicles in the Sustainable Engineering Solutions BU and the Renewable Sources & Storage Development BU.
  • In the context of promoting the use of natural gas as a transition fuel for the “green energy” era, the construction of the new combined cycle power plant with natural gas (CCGT) was completed at the end of 2021, making the Agios Nikolaos Energy Center in Viotia a new national energy center. The new plant has a thermal efficiency of over 63%, capacity over 826MW as well as the option to utilize fuel mixtures with hydrogen or biogas instead of natural gas, thus being a powerful means of achieving the MYTILINEOS climate targets. Today, it is the most powerful power plant in the country and one of the largest power plants in Europe, enhancing and ensuring the country's electricity efficiency and the energy transition.
  • Within 2021, MYTILINEOS proceeded to the creation of an integrated system of recording the Scope 3 sources and measuring the relevant emissions, from all its Business Units. Through this exercise, the Company identified for the first time the material indirect Scope 3 emissions categories, which will be published in the 2021 Sustainable Development Report, while it is already looking into ways to reduce its Scope 3 emissions.
  • MYTILINEOS implements systematic procedures for monitoring and ensuring compliance with the legislation, obtaining the statutory greenhouse gas emission permits and submitting the relevant reports, while participating through the Metallurgy and Power & Gas Business Units in the EU Emissions Trading Scheme (EU ETS) since 2013. At the same time, MYTILINEOS has installed all the necessary systems for the regular monitoring of CO2, Fluorine and PFCs and other gaseous pollutants (NOx, SOx and Particulate Matter) carrying out continuous measurements. MYTILINEOS systematically applies Best Available Techniques (BATs) in its production processes and ensures the proper maintenance and modernization of equipment.
