Environmental Dimension Assessment Procedure

HomePolicy and ProceduresEnvironmental Dimension Assessment Procedure

1. Purpose and Scope

The purpose of this procedure is to determine the environmental aspects of all activities and services and to evaluate their impacts within the scope of the environmental management system that Data Market can control and influence, taking into account planned and new developments, new or modified activities and services. It is aimed to reduce costs by reducing the use of natural resources, energy, and waste production, and to plan and implement relevant actions within the framework of compliance with environmental legislation.

This procedure covers the services and activities provided within Data Market and all sites. Environmental Dimension Management;

It includes all activities that can be controlled and influenced:

  • Supply Chain Management
  • Management of Activities
  • Management of subcontracting activities
  • Management of changes (capacity expansion, organizational changes, etc.)
  • Based on the management of temporary activities.

2. Responsibilities

Responsible Department Main Responsibilities
Source Management and Administrative Affairs To realize the relevant processes and operations within the scope of ISO 14001 Environmental Management System
Corporative Governance To realize the relevant processes and operations within the scope of ISO 14001 Environmental Management System

3. Definitions & Abbreviations

3.1. Definitions

Definition Explanation
Environment The environment in which an organization carries out its activities, including air, water, soil, natural resources, flora, fauna and people, and the relationship between them.
Environmental Dimension An element of an organization’s activities or products or services that can interact with the environment.
Environmental Impact Any positive or negative change to the environment resulting, in whole or in part, from the environmental aspects of an organization.
Significant Environmental Aspects Aspects of activities, products and services that may have a significant impact on the environment and all aspects that need to be kept under control and/or improved.
Environmental Accident Unexpected event that may cause environmental pollution.

3.2 Application Details

3.2.1 Determination of Environmental Dimensions and Impacts

A survey covering all work areas and activities is conducted by the Environmental Management Representative and environmental dimensions are determined. It is ensured that the environmental dimensions of the organization’s own activities and services are defined within the scope of the defined environmental management system that the organization can control and influence, taking into account planned or new developments, new or modified activities, and Services.

A team is formed with employees from the relevant departments under the coordination of the Environmental Management Representative to determine the environmental aspects.

By determining all activities carried out both at the beginning of the work and in the following periods on a departmental basis, the environmental dimensions that may occur are defined, taking into account the inputs, outputs and emergencies of these activities. While defining these dimensions, normal, abnormal, and emergency situations, relevant legislation and legal requirements are taken as basis.

Following the determination of environmental dimensions, it is decided how the environment will be affected. Employees, subcontractors, and visitors, whether existing control methods are adequate, neighboring facilities and the receiving environment are taken into consideration.

3.2.2 Evaluation of Environmental Dimensions and Impacts

“Environmental Dimensions Assessment Form” is used during these studies.

Dimensions are classified as “Normal” (N) if they are caused by routine activities, “Abnormal” (AN) if they are caused by non-routine activities (non-routine-incidental maintenance activities, revisions, capacity increase, organizational changes, temporary activities, etc.), and “Emergency” (AD) if they are caused by emergencies. It is also checked whether there are any legal requirements for the relevant environmental aspect and impact.

The coordination responsibility for determining the Environmental Impact Score is in the hands of the Management Representative. Assessment forms are sent to department managers for their opinions and published on the system by the Management Representative.
During the assessment, the duration/severity of the impact and the frequency/likelihood of occurrence are determined for the determined environmental dimensions. The information given below is used in this determination. Then the duration/severity of the impact is multiplied by the probability/frequency of occurrence.

Process controls are determined for significant environmental aspects, action plans are prepared for very high and significant environmental impacts and the Improvement Areas process is applied.

  • In case of emergencies, the environmental impact is “Significant”.
  • Legal Necessity : 0: No Law, 1: Law is available
Duration/Severity of Impact:
5 Very High Severity Large-scale, permanent environmental disaster
Mass deaths of living beings
Permanent and large-scale destruction of ecological balance
Indefinite cessation of work
4 High Severity Small-scale, permanent environmental disaster
Fatal effects or permanent damage to some living organisms
Permanent destruction of the ecological balance to a small extent
Work stops for a certain period of time
3 Moderate Severity Large-scale, remediable environmental impact
Temporary negative impact on living conditions
Temporary negative impact on ecological balance
Suspension of work until adverse effects are eliminated
2 Low Severity Short-term, remediable environmental pollution limited to the work area
Temporary negative impact on living organisms
Short-term and temporary negative impact on ecological balance
Work does not stop, action is taken
1 Very Low Severity Very short-term, remediable and insignificant environmental impact
No negative impact on living organisms
No negative impact on ecological balance
No action taken


Frequency/Probability of Impact:
5 Very High Probability (Occurs on a Daily Basis)
4 High Probability (at least once a month)
3 Moderate Probability (Occurs once every 3 months or less)
2 Low Probability (Occurs once every 6 months or less)
1 Very Low Probability (Occurs Once a Year or Less)
Impact Score:

Very High Environmental Impact: The activity cannot be continued without making improvements on the issues with a score of 20 and above as a result of the assessment.
Significant Environmental Impact: Activities can be continued with temporary measures for issues with 12-19 points or impact severity=5 as a result of the assessment. However, improvements should be made taking into account technological and financial priorities.
Medium Environmental Impact: For issues with a score of 5-11 or impact severity=4, activities can be continued with operational controls under supervision. Long-term improvement plans are made by considering technological and financial priorities.
Insignificant Environmental Impact: There is no need for operational controls and additional improvement work on issues with a score of 4 or less as a result of the assessment.
At the same time, in case of any legal regulations, the Environmental Impact is considered significant and operational controls are taken.

3.2.3 Reviewing of Environmental Dimensions and Impacts

The “Environmental Aspects Assessment Form” is reviewed once a year by the Environmental Management Representative. However, changes that may occur in the activities during the year, temporary works, new process commissioning or removal, emergencies, environmental accidents, before and after corrective and preventive actions, emergence of legal requirements or changes related to legal requirements, organizational changes, etc. requires re-evaluation without waiting for a one-year period.
