CSN is one of the most efficient integrated steel complexes in the world, with emphasis on five sectors: siderurgia, mining, logistics, cement and energy . So that you can learn more about our performance in relation to ESG issues, delve into important topics and clarify doubts about the Company's business, check out our Q&A session.

Common questions

CSN seeks to include the ESG concept in its governance structure, which has policies, structures and tools to integrate socio-environmental aspects and the sustainability agenda into strategic decision-making. 

The company has evolved in the definition of corporate structures to identify risks and opportunities, support the definition of ESG goals and monitor the evolution of all businesses towards these objectives. In the third quarter of 2021, the ESG Committee – which advises the Board of Directors – held its first meeting and approved the creation of the Integrated ESG Management Commission, made up of ambassadors (company employees) to promote an integrated model of innovation and sustainability in company.

Yes, our programs and projects have been briging significant results in reducing water consumption across the group. In mining, for example, our tailings filtration processes make it possible to recover 92% of the water contained in the filtered material and in the Central Plant, through investments in new technologies, the water recirculation rate increased from 79% in 2018 to 87% in 2020 and will reach 95% in 2023.  In the steel industry, currently, the UPV (President Vargas Plant) reached a water recirculation rate of 93.6% with the help of some projects such as the Implementation of water reuse from the Carboquímica heat exchangers and the Effluent Treatment Station ( ETE) of the Raw Materials Yard, in addition to the recirculation of rainwater and industrial water from the lime plant. 

In addition, as a pioneer in the sector, the UPV developed its Water Footprint study. This mapping makes it possible to map the entire water cycle in the production process and identify opportunities for improvement, with an assessment of costs and positive impacts of projects to improve performance. The study was also carried out in 2021 at CSN mining and as a result, opportunities were identified to improve water management throughout the iron ore production cycle. 

The environmental management system at CSN is managed by the sustainability department with the help of the Internal Corporate Environmental Management Committee (CIGA - corporative) which is led by the corporate environmental coordination and composed of professionals from the environmental areas of the operating units. This group meets monthly, aiming to maintain the continuous improvement of the implemented EMS, as well as detect and prevent possible environmental impacts. 

Yes. The CSN follows the performance evaluation model by Ciclo de Gente, using the 9Box methodology and tool. We ran our People Cycle where all employees had the opportunity to receive and give feedback regarding their current situation and their career expectations. 

The Cycle consists of the following steps: evaluation - calibration/people committee - feedback - career & succession - preparation of the PDI - Development. Leaders are responsible for supporting the development of the team, in order to make them better professionals than themselves, thus ensuring the growth of people and the continuity of CSN, through the career & succession program. 

After the evaluation, we carried out the CSN Group's 9Boxes and implemented the calibration in the People Committee, resulting in the “inverted L”, mapping the company's talents and potential. 

The CSN's Occupational Health and Safety Management System is based on three objectives that guide all our actions: A safe environment, Awareness of risks and Improvement in the performance of processes. We are constantly evolving in accident prevention, always seeking to assess the potential of certain situations that could lead to fatal or highly serious accidents. 

Our strategy is in the task of identifying and preventing the risk of dangerous situations before they can lead to serious and fatal accidents. As practical measures we take, we have a program to identify signs of potential fatigue in operators of large equipment, the Alcohol and Narcotics Use Prevention Program to identify use at work and provide support, as well as an intelligent system to predict risks. accident in the work environment. 

In addition, the Company defined the guidelines for its Occupational Health and Safety Management System through the SSO management manual, the corporate reference aims to consolidate the guidelines and Health and Safety Policy, in addition to the responsibilities and authorities to be disseminated and practiced by all employees and suppliers of all levels and in all processes of the organization. It is important to mention that the guidelines in the management manual are applicable to all direct employees and suppliers who are authorized to access CSN group units to perform services. 

Currently, 90% of our operating units are ISO 14001 certified 

Yes. In 2021, we completed the qualitative assessment of the risks and opportunities related to climate change for all CSN segments, based on the TCFD (Task Force for Climate Related Financial Disclosures) guidelines.

We maintain a continuous dialogue with the communities through communication channels (green line) and open and transparent relationship programs to address any issues observed by the communities, such as: suggestions, criticism and praise about our operations, as well as clarifying doubts, including details on the environmental management of our main impacts. In this way, we operate with transparency and in a collaborative way in the construction of solutions and improvement of our management 

Based on the Mining Dams Emergency Plan (PAEBM), the Company constantly carries out studies and promotes the registration of families in areas close to the dams, in accordance with international recommendations such as Dam Safety Guidelines – Dam Break Inundation Analysis and Downstream Hazard Classification, prepared by the Washington State Department of Ecology. The objective of the studies and registration is to monitor the families inserted within the Auto Rescue Zone (ZAS) and Secondary Rescue Zone (ZSS), develop social assistance actions, define escape routes and mitigate damage caused by a hypothetical dam break, in other words, rupture of the complex's dam. 


In addition, CSN seeks to analyze and monitor all possible impacts in order to mitigate them throughout the life cycle of projects and operational processes, which includes: 


  • -Carry out environmental control, monitoring, compensation and mitigation programs throughout the life of the project.

  • -Environmental Impact Study (EIS): Before a project is installed, an analysis of flora, fauna, water resources, soil, atmosphere and social aspects is carried out with the local community through surveys and public hearings. 

  • -Air quality monitoring: At the Presidente Vargas Steelworks, in Volta Redonda (RJ), there are three automatic air quality monitoring stations, five semi-automatic and meteorological stations that contribute to the efficiency of environmental controls and air quality indicators. The data are reported in real time to the state environmental agency, which consolidates the information and disseminates the Air Quality Index (IQAr) to the community. This monitoring, as in the Cimentos plants in Volta Redonda (RJ) and Arcos (MG), is carried out through isokinetic and continuous measurements, measured by automatic meters of particulate materials and gases. CSN Mineração operates four monitoring stations, two of which are meteorological and two for air quality, and are part of the Optimized Network for Monitoring Air Quality in Congonhas and the region.  

CSN offers 4 reporting channels (telephone, email, mail and website), respecting the premise of anonymity, secrecy and the guarantee of non-retaliation in the treatment of reports, available to its employees, service providers, suppliers, customers and the community in general, to receive information about deviations or transgressions that may affect the policies, guidelines and rules of the Company or its companies. Reports received through these channels, except correspondence, are handled by a third-party company specialized in receiving and initially handling reports, trained in interview techniques, content analysis and risk management, which interacts in order to obtain as much detail as possible regarding to the fact reported, and forwarded to the Audit, Risks and Compliance Board, which is responsible for carrying out investigations received through the reporting channels and reporting the results to the Audit Committee, which acts as the supervisory body of corporate governance activities. In addition, as previously mentioned, at its main units, CSN maintains an open and free communication channel with the external public, the “Green Line”, which aims to meet environmental demands.
