Environmental Risk Register

Back to Glossary

Summary

An environmental risk register is a structured tool used to identify, record, prioritise and monitor environmental risks throughout a project.

It provides project teams with a central record of environmental hazards, risk ratings, controls, responsibilities and review requirements, helping environmental risks remain visible and actively managed from planning through construction and ongoing operations.

Definition

An environmental risk register is a documented record of identified environmental risks, their likelihood and potential consequences, the controls used to manage them, and the people responsible for implementing and monitoring those controls.

Environmental risk registers are typically developed following an environmental risk assessment and updated as site conditions, project activities or environmental risks change.

A register may include:

  • Environmental hazard or risk
  • Potential cause and consequence
  • Likelihood and consequence ratings
  • Initial risk rating
  • Existing environmental controls
  • Additional mitigation measures
  • Residual risk rating
  • Responsible person or risk owner
  • Monitoring requirements
  • Review dates and actions

Why Environmental Risk Registers Matter

An environmental risk register provides a practical framework for identifying, prioritising, monitoring and managing environmental risks throughout a project.

Centralising Environmental Risks

A risk register provides a central record of:

  • Identified environmental hazards and risks
  • Potential environmental impacts
  • Likelihood and consequence ratings
  • Existing and proposed controls
  • Residual risk levels
  • Assigned responsibilities
  • Monitoring and review requirements

This gives project teams and contractors a consistent understanding of environmental risks and how they are being managed.

Supporting Proactive Environmental Risk Management

Rather than responding to environmental issues after they occur, a risk register helps project teams proactively manage potential impacts.

It can support:

  • Regular review of existing risks
  • Identification of new or emerging risks
  • Prioritisation of higher-risk activities
  • Implementation of mitigation measures
  • Monitoring of control effectiveness
  • Escalation where risks exceed acceptable levels

The register can translate findings from an Environmental Risk Assessment into practical controls and ongoing management actions.

Supporting Environmental Compliance and Due Diligence

Depending on the project, an environmental risk register may help demonstrate that environmental risks have been systematically identified and managed in accordance with:

  • Development consent conditions
  • Environmental approvals
  • Relevant environmental legislation and guidance
  • Principal contractor requirements
  • Project-specific environmental requirements
  • Environmental management plans

Risk registers can also provide supporting documentation during environmental audits, compliance reviews and project reporting.

Improving Communication and Accountability

A well-maintained environmental risk register clearly establishes:

  • Who is responsible for managing each risk
  • What environmental controls are required
  • When actions must be completed
  • How controls will be monitored
  • When risks need to be reviewed or reassessed

This supports clearer communication and accountability between project managers, environmental consultants, contractors and other relevant stakeholders.

Supporting Environmental Decision-Making

Environmental risks can change as a project progresses.

Maintaining an up-to-date register helps teams respond to:

  • Changes in construction methodology
  • New site conditions
  • Unexpected contamination
  • Environmental incidents
  • Changes to project scope
  • New monitoring results
  • Changes to approval or compliance requirements

This allows environmental management measures to be reviewed and adjusted as the project evolves.

When Is an Environmental Risk Register Used?

Environmental risk registers can be used throughout the project lifecycle where environmental risks need to be actively identified, controlled and monitored.

Planning and Design

During project planning and design, an environmental risk register can be used to:

  • Record risks identified during environmental assessments
  • Identify environmental constraints
  • Prioritise higher-risk activities
  • Inform project design and planning decisions
  • Develop appropriate mitigation measures
  • Support environmental management planning

The register may draw on findings from Environmental Risk Assessments, environmental due diligence, site investigations and other environmental assessments.

Construction

Environmental risk registers are commonly used during construction to identify and manage risks associated with:

  • Dust and air quality
  • Noise and vibration
  • Erosion and sediment
  • Surface water and groundwater
  • Dewatering
  • Contaminated soil
  • Asbestos and unexpected finds
  • Waste storage and disposal
  • Fuel and chemical handling
  • Spills and environmental incidents
  • Impacts on surrounding sensitive receptors

The environmental risk register may form part of a broader Construction Environmental Management Plan (CEMP), helping translate identified risks into specific controls, responsibilities and monitoring requirements.

Contaminated Land and Remediation Projects

Environmental risk registers can also support contaminated land and remediation projects by helping teams:

  • Track identified contamination risks
  • Record potential exposure pathways and receptors
  • Assign remediation and management actions
  • Monitor environmental controls
  • Respond to unexpected contamination
  • Track outstanding environmental actions

These activities may be undertaken alongside a Remediation Action Plan (RAP) and associated remediation, validation and monitoring programs.

Environmental Monitoring and Compliance

A risk register may also be maintained throughout construction or ongoing site operations to:

  • Track environmental monitoring requirements
  • Record changes in environmental risk
  • Review the effectiveness of controls
  • Support environmental audits
  • Manage corrective actions
  • Document environmental incidents and responses
  • Support ongoing compliance reporting

Regular review helps ensure the register remains relevant as project conditions and environmental risks change.
