Sustainability
Sustainability is an integral part of our strategic vision: as an energy transition company, we are committed every day to contributing to a concrete, responsible, and measurable energy transition. Inspired by ESG principles – Environmental, Social, and Governance – we combine technological innovation with environmental protection, promote an inclusive work environment, and adopt governance practices based on ethics, transparency, and legality.
Our actions are guided by the European Corporate Sustainability Reporting Directive (CSRD), which requires companies to transparently report their environmental, social, and governance (ESG) performance, as well as by the international standards set by the World Economic Forum (WEF). This approach enables us to ensure consistency, accountability, and long-term value creation. In doing so, we generate a positive impact on local communities, people, and future generations by integrating sustainability into every aspect of our business.
As part of the development of its sustainability strategy, Altenia adopts independent ESG assessments to monitor its level of maturity across environmental, social, and organisational factors over time. These include the Achilles Sustainability Rating, in which the company achieved a score of 4 out of 5 stars, and the Synesgy–CRIBIS assessment, with a B rating (“Good”). Both are used as benchmarking and measurement tools within energy and infrastructure supply chains. The assessments examine areas such as ESG risk management, health and safety, ethics, compliance, and process transparency, supporting a structured approach to continuous improvement and long-term value creation.
Environmental
At Altenia, environmental sustainability is a core element of our strategic decision-making. We minimize environmental impact at every stage of our operations by investing in green technologies and promoting efficient resource use. Through a range of initiatives, we state our commitment to transparent and verifiable sustainability models aligned with international standards.
Certifications
We adopt a scientific and measurable approach to environmental management, based on compliance with national and international regulations and adherence to the most advanced standards, as demonstrated by our ISO 14001 certification. We continuously monitor our carbon footprint using recognized tools such as Ecovadis and Open-es, with the goal of systematically reducing CO₂ emissions and improving efficiency across the entire value chain.
Projects
In 2024, Altenia took part in the data collection initiative promoted by the Terna Group as part of the Science Based Targets for Nature (SBTN) project—an international effort that helps companies set measurable goals to reduce their impact on natural ecosystems and contribute concretely to protecting the planet. This activity laid the groundwork for applying Life Cycle Assessment (LCA), an analysis that evaluates environmental impact across the entire life cycle of processes and products, from production to disposal.
Social
We believe that sustainability comes first and foremost through people. This is why we promote a work environment based on listening, respect, fairness and inclusion. Our social commitment is manifested in concrete actions towards empowering human resources, ensuring occupational safety, and promoting diversity.
Diversity, Equity and Inclusion
We actively promote Diversity, Equity & Inclusion (DE&I) policies, in alignment with the Terna Group’s corporate guidelines. Our commitment is to fostering a workplace where every individual—regardless of gender, age, ability, or personal background—can fully realize their potential within an equitable and inclusive environment.
Continuous Learning
We are committed to high-quality training programs that support continuous learning, with the goal of developing both the technical and cross-functional skills of our people. We believe in internal awareness and knowledge sharing: through dedicated internal communication initiatives, we engage employees on sustainable practices and responsible behaviors.
Governance
At Altenia, robust and accountable governance is the fundamental prerequisite for building trust, generating long-term value and ensuring regulatory compliance. Our approach is based on ethical principles, decision-making transparency and conscious risk management.
Ethic Code
We adopt the Code of Ethics of the Terna Group, which defines the expected behaviors and strategic guidelines with particular attention to sustainability, the environment and respect for the territory.
Organizational, Management and Control Model
We have implemented Organizational Model 231, in line with Legislative Decree 231/2001, as an internal management system for the prevention of legal, financial and reputational risks.
Prevention of corruption
We are actively engaged in preventing corruption through the adoption of policies and procedures that promote legality and compliance with current regulations.
Whistleblowing
In line with the values of the Terna Group, we adopt a proactive approach to risk prevention to ensure responsible and sustainable business management. We provide dedicated channels for reporting potential violations, ensuring transparency, fairness, and integrity across all company activities
