Sidenor 2021 Sustainability Report. Non-financial information statement

4 We are undoubtedly living one of the most complicated times in our history. For two years, we have gone through an unprecedented health crisis which has shaken the foundations of the Western economies and has been extraordinarily demanding at individual and family level. We hadn’t emerged from this health crisis yet when energy - both electricity and gas – took a catastrophic turn, with price increases that were unprecedented in the history of the Company. And yet, we were able, in this highly unfavourable context, to carry out a profound technological transformation in our facilities, which places us in optimal conditions to address the needs of our customers in the future. The challenge is now to take a leap forward and nothing, nowadays, makes probably more sense than giving priority to environmental sustainability. At Sidenor, we have decided to turn respect for the environment into a competitive advantage. We want to be the first European special steel manufacturer to provide its customers with green steel, with net-zero CO 2 emissions. For this purpose, Sidenor will deploy a large- scale strategic plan which will include the totality of its industrial processes. First of all, the Company will maintain its actions aiming at ensuring an electricity supply of fully renewable origin, including, if necessary, the purchase of wind and photovoltaic generation assets. In addition, Sidenor will launch projects to improve its energy sufficiency in all its facilities, which will translate into a significant decrease in emissions. In a first phase, by the year 2030, the Company will have reduced its CO 2 emissions by 60% compared with 2005 - above the European Union target of 55%. In a second phase, in which we will develop the use of hydrogen as a substitute for natural gas, we will reach the objective of net zero emissions. We will not, however, limit ourselves to CO 2 , although it is the axis of all actions aimed at controlling climate change. More broadly, we have launched numerous initiatives with the aim of minimising all types of emissions into the atmosphere, as well as reducing and, in addition, recovering the vast majority of our waste. Ultimately, Sidenor endorses the environmental sustainability priorities that society demands, and is launching a comprehensive strategic plan in which it intends to involve all its people, with a view to leading the evolution towards green steel in the European special steel market.
