Carbon Emissions Reporting for Infrastructure Companies: Compliance Guide

Infrastructure assets—whether in transport, energy networks, water systems, or social infrastructure are long lived, capital intensive, and deeply embedded in the economy. They also carry significant and often underreported carbon footprints, both during construction and across decades of operation.

As governments and regulators intensify their focus on climate risk, infrastructure operators are facing a new reality: carbon emissions reporting is no longer optional. From 2025–2026, mandatory disclosures under frameworks such as the Australian Sustainability Reporting Standards and AASB S2 will require infrastructure companies to provide detailed, auditable climate information.

At the same time, emissions transparency is increasingly tied to access to capital, project approvals, and contract awards. For infrastructure companies, reporting is not just about compliance it is about project viability and long-term value.

This guide outlines what infrastructure companies need to know, the challenges they face, and how to prepare for the 2026 regulatory landscape.

Why Carbon Reporting Matters for Infrastructure Companies

Public Funding and Regulatory Scrutiny

Many infrastructure projects are funded or supported by government entities. As a result, they are subject to heightened scrutiny around environmental and social impacts.

Transparent carbon reporting is now a key requirement for:

• Securing public funding
• Meeting regulatory approvals
• Demonstrating alignment with national climate targets

ESG Requirements and Investor Expectations

Institutional investors are increasingly allocating capital based on ESG performance. Infrastructure assets, often held in long-term portfolios, must demonstrate:

• Clear emissions baselines
• Credible decarbonisation pathways
• Alignment with net-zero commitments

Contract and Tender Conditions

Carbon performance is becoming a differentiator in procurement processes. Infrastructure companies are increasingly required to:

• Disclose project-level emissions
• Meet emissions thresholds
• Provide ongoing reporting throughout the asset lifecycle

Reputation and Stakeholder Management

Large infrastructure projects attract public attention. Poor emissions performance or lack of transparency can lead to:

• Community opposition
• Reputational damage
• Delays in project delivery

Main Sources of Emissions in Infrastructure

Construction Activities

Construction is one of the most emissions-intensive phases of an infrastructure asset’s lifecycle. Key sources include:

• Heavy equipment and machinery
• Temporary power generation
• On-site fuel use

Materials: Steel and Concrete

Embodied carbon in materials is a major contributor to lifecycle emissions. Steel and concrete, in particular, have high emissions intensity and are often sourced through complex global supply chains.

Transport and Logistics

Transporting materials, equipment, and personnel contributes to both direct and indirect emissions, particularly for large-scale or remote projects.

Operations and Maintenance

Once operational, infrastructure assets continue to generate emissions through:

• Energy consumption
• Maintenance activities
• System inefficiencies

Supply Chains

Scope 3 emissions across supply chains covering materials, contractors, and services—are often the largest and least visible component of total emissions.

2026 Reporting Requirements: What Infrastructure Companies Must Do

From 2026, infrastructure companies will be required to comply with enhanced climate disclosure obligations under AASB S2.

Scope 1, 2 and 3 Emissions

Companies must report across all emissions scopes:

• Scope 1: Direct emissions from owned or controlled operations
• Scope 2: Indirect emissions from purchased energy
• Scope 3: Emissions across the value chain, including materials and contractors

For infrastructure, Scope 3 emissions—particularly embodied carbon—are often the most material.

Climate Risk Disclosure

Organisations must identify and disclose:

• Physical risks (e.g. extreme weather impacting assets)
• Transition risks (e.g. regulatory changes, carbon pricing)
• Financial impacts of climate risks

Transition Planning

Infrastructure companies must demonstrate how they will:

• Reduce emissions over time
• Align with climate targets
• Integrate decarbonisation into project planning and operations

Governance and Oversight

Boards and executive teams must show:

• Clear accountability for climate-related risks
• Integration into enterprise risk management
• Alignment with strategy and capital allocation

‍

Common Challenges for Infrastructure Companies

Multiple Contractors and Stakeholders

Infrastructure projects involve numerous contractors, subcontractors, and suppliers. This creates challenges in:

• Collecting consistent emissions data
• Ensuring compliance across the value chain
• Managing differing capabilities and standards

Project-Based Data Fragmentation

Emissions data is often managed at the project level, leading to:

• Fragmented datasets
• Inconsistent methodologies
• Limited visibility at the enterprise level

Long Asset Life Cycles

Infrastructure assets operate over decades, requiring:

• Long-term emissions tracking
• Ongoing reporting and updates
• Integration of historical and future data

Supplier Reporting Gaps

Many suppliers lack the capability or resources to provide accurate emissions data, resulting in:

• Low response rates
• Reliance on estimates
• Increased uncertainty

‍

How Infrastructure Companies Can Prepare

Implement Contractor Reporting Systems

Contractors must be embedded into the reporting process. Leading organisations are:

• Setting clear reporting requirements
• Providing tools and templates
• Integrating emissions reporting into contracts

Enable Project-Level Emissions Tracking

Granular tracking is essential. Companies should:

• Capture emissions data at the project level
• Standardise methodologies across projects
• Ensure consistency in reporting

Centralise Data and Systems

To achieve enterprise-wide reporting, organisations must:

• Consolidate data from multiple projects
• Implement centralised reporting platforms
• Automate data aggregation and calculations

Strengthen Governance Processes

Climate reporting must be embedded into governance structures:

• Board oversight of climate risks
• Defined roles and responsibilities
• Integration with enterprise risk management

Carbon Emission Reporting Software Can Help

Carbon emissions reporting is now a critical requirement for infrastructure companies. With mandatory disclosures coming into effect from 2025–2026, organisations must act quickly to build robust, scalable, and auditable reporting capabilities.

The implications go beyond compliance. Emissions transparency is increasingly linked to funding, procurement outcomes, and long-term asset value.

Infrastructure companies that invest early in integrated systems, strong governance, and effective contractor engagement will be better positioned to succeed in this evolving landscape.

Fair Supply supports this transition—providing the tools, data, and expertise required to deliver end-to-end, audit-ready carbon reporting across complex infrastructure portfolios.
