Introduction

0.1 Background

Achieving a balance between the environment, society and the economy is considered essential to meet the needs of the present without compromising the ability of future generations to meet their needs. Sustainable development as a goal is achieved by balancing the three pillars of sustainability.

Societal expectations for sustainable development, transparency and accountability have evolved with increasingly stringent legislation and growing pressures on the environment from pollution, inefficient use of resources, improper waste management, climate change, degradation of ecosystems and loss of biodiversity. Undermining the environment can carry financial, social and business consequences, not just environmental implications.

These expectations have led organizations to adopt a systematic approach to environmental management by implementing environmental management systems with the aim of contributing to the environmental pillar of sustainability. As a result, organizations are better positioned to respond to the needs and expectations of interested parties and to meet the organization’s compliance obligations.

0.2 Aim of an environmental management system

This document provides organizations with a framework to protect the environment and respond to changing environmental conditions in balance with socio-economic needs. It specifies requirements that enable an organization to achieve the intended outcomes it sets for its environmental management system.

A systematic approach to environmental management provides top management with information to build success over the long term and create options for contributing to sustainable development by:

protecting the environment through preventing or mitigating adverse environmental impacts;
mitigating the potential adverse effect of environmental conditions on the organization;
assisting the organization to meet its compliance obligations;
enhancing environmental performance;
controlling or influencing the way the organization’s products and services are designed, manufactured, distributed, consumed and disposed of by using a life cycle perspective that prevents adverse environmental impacts from being unintentionally shifted elsewhere within the life cycle;
achieving financial and operational benefits that result from implementing environmentally sound alternatives that strengthen the organization’s market position;
communicating environmental information to relevant interested parties.

0.3 Success factors

The success of an environmental management system depends on commitment from all levels and functions of the organization, led by top management. Organizations can leverage opportunities to prevent or mitigate adverse environmental impacts and enhance beneficial environmental impacts, particularly those with strategic and competitive advantages. Top management can effectively address its risks and opportunities by integrating environmental management into the organization’s business processes, strategic direction and decision-making, aligning them with other business priorities, and incorporating environmental governance into its overall management system. Demonstration of successful implementation of this document can be used to assure interested parties that an effective environmental management system is in place. Adoption of the requirements in this document, however, will not in itself guarantee optimal environmental outcomes.

Application of the requirements in this document can differ from one organization to another due to the context of the organization. Two organizations can carry out similar activities but can have different compliance obligations, commitments in their environmental policy, environmental technologies and environmental performance goals, yet both can conform to the requirements of this document.

The level of detail and complexity of the environmental management system will vary depending on the context of the organization, the scope of its environmental management system, its compliance obligations, and the nature of its activities, products and services, including its environmental aspects and associated environmental impacts.

0.4 Plan-Do-Check-Act model

The basis for the approach underlying an environmental management system is founded on the concept of Plan-Do-Check-Act (PDCA). The PDCA model provides an iterative process used by organizations to achieve continual improvement. It can be applied to an environmental management system and to each of its individual elements. It is briefly described as follows:

Plan: Establish environmental objectives and processes necessary to deliver results in accordance with the organization’s environmental policy.
Do: Implement the processes as planned.
Check: Monitor and measure processes against the environmental policy, including its commitments, environmental objectives and operating criteria, and report the results.
Act: Take actions to continually improve.

Figure 1 shows how the framework used in this document can be integrated into a PDCA model, which can help new and existing users to understand the importance of a systems approach.

0.5 Contents of this document

This document conforms to ISO requirements for management system standards. These requirements include a harmonized structure, identical core text and common terms with core definitions, designed to benefit users implementing multiple ISO management system standards.

This document does not include requirements specific to other management systems, such as those for quality, occupational health and safety, energy or financial management. However, this document enables an organization to use a common approach and risk-based thinking to integrate its environmental management system with the requirements of other management systems.

This document contains the requirements used to assess conformity. An organization that wishes to demonstrate conformity with this document can do so by:

making a self-determination and self-declaration; or
seeking confirmation of its conformance by parties having an interest in the organization, such as customers; or
seeking confirmation of its self-declaration by a party external to the organization; or
seeking certification/registration of its environmental management system by an external organization.

Annex A provides explanatory information to prevent misinterpretation of the requirements of this document. Guidance on applying the ISO 14001 framework to specific environmental topic areas is addressed in the ISO 14002 series. Implementation guidance on environmental management systems is included in ISO 14004.

Clause A.3 provides further insights on specific words and phrases used in this document to enhance the understanding of concepts that are relevant to an environmental management system.

1 Scope

This document specifies the requirements for an environmental management system that an organization can use to enhance its environmental performance. It is intended for use by an organization seeking to manage its environmental responsibilities in a systematic manner that contributes to the environmental pillar of sustainability.

This document helps an organization to achieve the intended outcomes of its environmental management system, which provide value for the environment, the organization itself and interested parties. The intended outcomes of an environmental management system include:

enhancing environmental performance;
meeting compliance obligations;
achieving environmental objectives.

This document is applicable to any organization, regardless of size, type or nature, and applies to the environmental aspects of its activities, products and services that the organization determines it can either control or influence considering a life cycle perspective.
