Code of Business Conduct

At ENKA we work to sustain a culture in which behaviors and decisions at all levels are fully aligned with ENKA’s core values and business principles.

Our Legal Department monitors external legal and regulatory developments and provides legal advice. ENKA Employees implement required policies, standards and procedures and embed requirements in day-to-day processes, with support and directions from Corporate Quality, HSE, Sustainability and HR Departments.

Our leaders play an essential role, setting the right example through their own behavior. They also lay out the clear expectation that all business plans and activities are undertaken in a responsible, safe and compliant manner.

Our company-wide Code of Business Conduct helps our employees to put our vision and values into practice. The code defines basic rules, standards, and behaviors for ENKA employees and directs them to available resources and support.

ENKA expects all persons, groups and organizations with which it works to comply with its culture of ethics. In this regard, ENKA clearly demands from all suppliers, subcontractors, consultants and business partners (altogether referred to as “Suppliers”) to comply with the ENKA Supplier Code of Conduct during all their activities. ENKA Supplier Code of Conduct was formed to describe the way ENKA does business  and to communicate the robust rules that ENKA’s suppliers, subcontractors, consultants and other business partners must adhere at all times.

ENKA Code of Business Conduct and Supplier Code of Conduct are reviewed annually and revised in case of necessity.

Respect for human rights is a fundamental value of ENKA Insaat ve Sanayi A.S. (ENKA). ENKA conducts all its business activities in a respectful manner to the human rights stated in the Universal Declaration of Human Rights and in compliance with the requirements of United Nations Global Compact which ENKA is a signatory, and applicable laws and in accordance with the International Labor Organization (ILO) conventions. During our all risk assessments, we always assess human rights related risks and expect from our stakeholders to perform a similar assessment as well.

At ENKA, we strive to respect and promote human rights in accordance with the UN Guiding Principles on Business and Human Rights. Our aim is to create a positive presence and legacy on the communities and societies in which we operate for having a required degree of social performance. Our Code of Business Conduct, Sustainability Policy and Health, Safety and Environment Policies as well as ENKA Social Community Engagement Management principles are corner stones in these endeavors.

The latest version of our Code of Business Conduct was launched on 27/ 12/ 2018. It is available in Turkish, English, Russian and Arabic for all countries we operate in and distributed throughout the Company. It reflects an in-depth global consultation on the salient human rights risks of the Company, which are the most severe potential impacts associated with our business. Our Code of Business Conduct applies to all projects and business units (i.e. corporate offices, representative offices and group companies) under the administrative control of ENKA and compliance with our Code is consistently monitored throughout our operations.

ENKA Code of Business Conduct includes the following twelve components:

  • Respect for Human Rights
  • Diversity and Inclusion
  • Harassment-Free Workplace
  • Freedom of Association and Collective Bargaining
  • Safe and Healthy Workplace
  • Workplace Security
  • Preventing Child Labor, Forced Labor and Human Trafficking
  • Social Community Engagement
  • Fair Employment Practices
  • Employee Personal Information
  • Guidance and Reporting for Employees
  • Suppliers

At ENKA, it is every employee’s responsibility to maintain a work environment that reflects respect for human rights and is free from all discrimination and harassment, aligned with our Code of Business Conduct. If any employee believes that someone is violating the Code and/or the law, they are asked to report it immediately to their manager, Corporate Sustainability Department, ENKA Legal Department or Ethics Hotline. Potential issues or received allegations will be addressed and investigated internally, as well as co-operative participation with internal investigations if needed. In cases of violating the law, our Code and human rights values may lead to disciplinary, legal or criminal action being taken against individuals. We also conduct regular ethics & compliance audits against the ENKA Code of Business Conduct, within the Company and third party premises, having a business relation with ENKA, in order to ensure compliance.

ENKA considers audits and assessments as a core element of continual improvement and risk identification. In this context ENKA internal audit teams conduct audits to assess the compliance against ISO 9001, ISO 27001, ISO 14001, ISO 45001 standards, Corporate Quality, HSE (Health, Safety, and Environment), Sustainability, Finance and Accounting, Human Resources requirements and procedures, ENKA Code of Business Conduct, local and international laws and regulations and contract requirements. In 2019, all ENKA projects and 78% of ENKA subsidiaries were audited by internal audit teams. In addition to the regular audits, Ethics and Compliance audits were put into practice to assess the ENKA projects and subsidiaries against human rights, worker rights and anti-corruption and anti-bribery practices. Within the context of Ethics and Compliance audits a part of ENKA’s projects and subsidiaries operating in Turkey, Russia, Kazakhstan, Georgia and Iraq were assessed against human rights, worker rights and anti-corruption and anti-bribery practices.

We also use Supplier Sustainability Audit Program as a tool to manage the supply chain risks and ensure that our suppliers and subcontractors complies with ENKA’s and international standards. We started performing supplier sustainability audits to assess their compliance on environmental, social and ethical management, human rights and labor, occupational health and safety and anti-bribery and anti-corruption policies. Corrective actions are planned for identified nonconformities and improvement areas and their implementations are monitored regularly. We aim to widen our area of assessment with more suppliers and subcontractors with the contributions of our subsidiaries each year.

In addition to the audits performed by our audit teams, ENKA’s management systems are assessed by 3rd party auditors. Accordingly each year;

  • BSI performs Quality Management, Information Security Management and HSE Management systems audit annually against ISO 9001, ISO 27001, ISO 14001 and ISO 45001 standards
  • TÜV Nord and ASME perform Quality Control Management audits pertaining to technical capacity of business applications and workforce of the company against ASME codes and standards
  • KPMG performs annual financial statements audits against the requirements of International Financial Reporting Standards (“IFRS”), United States Generally Accepted Accounting Principles (“US GAAP”) and other standards promulgated by the regulators.

We are also working with our peers and other parties of the industry, governments and non-governmental organizations to support the integration of sustainability practices and business ethics into business strategies. Within this context, ENKA became an official member of the Business Council for Sustainable Development Turkey (BCSD) as of August 2018 and Ethics and Reputation Society (TEID) as of September 2018. We also became a member of Private Sector Volunteering Association (OSGD) in 2019.
