Construction is often seen as the moment when sustainability becomes visible – on-site practices, energy use, and building performance. But by the time a project reaches that stage, much of its environmental and social impact has already been set in motion.

Long before ground is broken, decisions around materials, production processes, and sourcing begin to shape the project’s ESG footprint in ways that are difficult to reverse.

This raises a quieter, less visible question: if the real impact starts earlier, are we looking in the right place when we measure and report construction sustainability?

In this article, we explore how ESG reporting in the construction and building materials industry extends beyond the building phase, why material-level data is becoming critical, and what this shift means for building materials manufacturers, industrial production groups, and multi-entity organisations aiming to manage ESG with transparency, accountability, and long-term impact in mind.

ESG in Construction Is Often Measured Too Late

When building materials manufacturers and construction companies approach ESG reporting, the focus almost always begins at the construction site. Energy use, machinery emissions, and on-site efficiency are treated as the main indicators of sustainability performance.

But this perspective only captures part of the picture.

A significant share of a building’s environmental impact is shaped before construction begins, through decisions around materials, sourcing, and production.

Despite this, ESG measurement in construction continues to prioritise on-site activity rather than upstream processes. This creates an incomplete view of impact, where key data from production and material decisions remains disconnected from reporting frameworks.

As a result, ESG reporting often reflects only what is visible during construction, rather than the full scope of how a building’s footprint is formed.

The Growing Role of Embodied Carbon in the Construction Sector

As ESG expectations in construction evolve, reporting is increasingly extending beyond operational performance toward the materials and processes that shape a project before construction begins.

This is where embodied carbon becomes an important reference point in ESG discussions.

Rather than focusing only on emissions from building use, embodied carbon draws attention to the environmental impact embedded in materials throughout production, sourcing, and delivery processes.

For building materials manufacturers and multi-entity production groups, this shifts the nature of ESG reporting.

It requires visibility not only at the project level, but across factories, supply chains, and logistics networks where these impacts originate.

As a result, ESG reporting in construction is moving toward a more connected approach that reflects how material-level decisions influence overall sustainability outcomes.

ESG Data Challenges Across the Construction Value Chain

For multi-entity building materials groups, ESG data does not sit in a single system or team. It is distributed across multiple business units, production sites, suppliers, and logistics partners, often operating across different systems and geographies.

This creates a fragmented data environment where information is difficult to collect, compare, and validate. Even when this data is available, it often lacks consistency in format, methodology, and measurement standards across production sites and business units, making it challenging to translate into reliable ESG reporting outputs.

For industrial organisations, this gap separates real activity on the production floor from what is ultimately reported at the group level.

Visibility is another constraint. For many organisations, insight into material origins, production methods, or upstream emissions remains limited, particularly when working with multiple tiers of suppliers across different regions.

In practice, much of this information is still managed through manual processes, spreadsheets, and disconnected tools. This not only slows down reporting cycles but also increases the risk of errors, gaps, and unverifiable data.

The challenge now is building a system that can capture, connect, and validate ESG data across the entire construction value chain.

Building a Strong ESG Data Foundation for Construction

What was once handled through isolated tools and manual inputs now requires a more structured approach. ESG reporting in construction depends on data that is not only available but also consistent, connected, and audit-ready.

This is driving a shift toward centralised, group-level ESG data environments, where information from across suppliers, production processes, and project activities can be brought together into a single, reliable source of truth. This is particularly critical for organisations managing ESG reporting across multiple entities, locations, and operational systems.

Standardisation plays a critical role in this transition. Without aligned formats, definitions, and calculation methods, even the most comprehensive datasets remain difficult to use in practice. Establishing common structures allows organisations to move from fragmented inputs to comparable, decision-ready insights.

At the same time, auditability is becoming a baseline requirement rather than an added layer. ESG data must be traceable, verifiable, and structured in a way that can withstand increasing regulatory and stakeholder scrutiny.

In response, many organisations are moving away from spreadsheet-based workflows toward digital systems designed to handle ESG data at scale.

ESG Reporting in Construction: How Construction Companies Are Operationalising ESG Reporting?

For many building materials groups, the shift toward structured ESG reporting begins with growing operational complexity.

ESG data is often managed across multiple entities, production sites, and systems, with reporting processes heavily reliant on spreadsheets, manual inputs, and disconnected workflows.

This creates limited visibility at the group level, increases the risk of errors, and makes it difficult to respond to auditor requirements or scale reporting over time.

One European building materials group, Fedrus International, faced exactly this challenge.

As reporting requirements evolved, Fedrus encountered growing challenges in managing ESG data across its organisation.

Existing tools were not sufficient to support group-level ESG reporting, particularly when responding to audit requirements and aligning data across multiple entities.
At the same time, reliance on a large number of spreadsheets created inefficiencies, increased the risk of errors, and made it difficult to maintain consistency across reporting cycles.

To address this, Fedrus set out to move beyond manual processes and establish a more scalable reporting structure. The goal was not only to improve efficiency but to ensure data accuracy, traceability, and the ability to report on a regular basis.

This led to the implementation of a structured ESG data platform built on Microsoft Cloud for Sustainability, enabling the integration of data from multiple sources into a centralised environment. Through this approach, ESG data could be standardised, validated, and transformed into audit-ready outputs.

As part of this transition, Fedrus also introduced automated data flows and calculation models, allowing key ESG metrics such as emissions intensity and safety performance to be tracked more consistently.

The result is a system that not only supports compliance requirements but also provides a more reliable foundation for ongoing ESG performance management.

ESG in Construction Starts Before It Begins

ESG in construction is no longer defined by what happens on-site alone. By the time a project reaches the building phase, much of its environmental impact has already been shaped by earlier decisions across materials, production, and supply chains.

This shift is changing how companies approach sustainability. It’s no longer enough to measure performance at the project level. Real progress depends on the ability to access, connect, and trust data across the entire value chain.

As expectations around transparency, auditability, and compliance continue to grow, building materials manufacturers and multi-entity industrial groups need to move beyond fragmented ESG reporting by establishing a structured, scalable, and audit-ready data foundation.

Terra Reporting helps organisations connect ESG data, streamline reporting processes, and build a scalable, audit-ready foundation for end-to-end sustainability visibility.
