How Nulla Can Help Sustainability and ESD Consultants

In the world of embodied carbon assessment, data accuracy and turnaround speed are critical. Yet even the most seasoned sustainability or ESD consultants can find their schedule eroded by manual tasks—chief among them, mapping quantities to carbon factors and updating models as BOQs evolve. Nulla is built to address exactly these pain points, acting as a carbon assessment copilot that turbocharges your workflow without replacing your professional judgement.

Embodied Carbon Policy in Australian Building Sector: Where We Stand and What’s Next

Australia’s built environment is responsible for nearly one-third of the nation’s carbon emissions, with embodied carbon (emissions from materials and construction) contributing a growing share. While operational energy is increasingly regulated, embodied emissions have only recently begun to receive policy attention. This article provides an overview of where Australia stands at both federal and state levels, how our efforts compare globally, and how embodied carbon fits within Australia’s broader net zero transition strategy.

Fixing the Carbon Data Puzzle in Australia’s Building Industry

Australia’s building industry is under pressure to reduce carbon emissions. From homes and commercial development to major infrastructure, professionals are increasingly trying to measure and reduce both embodied and operational carbon emissions. But there’s a big problem getting in the way: the carbon data is messy, inconsistent, and hard to consume. This challenge, often referred to as carbon data mapping, is now a daily frustration for architects, engineers, builders and sustainability consultants. It slows down projects, adds complexity and ultimately makes it harder to hit the climate goals.

Imported Building Materials: The Next Frontier in Australia’s Carbon Accounting Challenge

Australia’s building industry is undergoing a significant transformation as it moves towards low-carbon construction. While strong progress has been made in decarbonising locally produced materials such as concrete, steel, and timber, there remains a major blind spot in carbon planning: imported building materials. With Australia heavily reliant on global supply chains, addressing the carbon impact of these imports is becoming increasingly critical.

Understanding the Difference Between ISO 14067 Carbon Footprint Reports and EPDs Based on ISO 14025 and EN 15804

As carbon transparency becomes increasingly important in the construction and manufacturing sectors, two key tools have emerged for quantifying and disclosing the climate impacts of products: carbon footprint reports (CFRs) and Environmental Product Declarations (EPDs). While both report greenhouse gas (GHG) emissions, they are governed by different standards, follow distinct procedures, and serve different purposes. This article outlines the critical differences between these two approaches, focusing on their standards, verification, comparability, and alignment with Product Category Rules (PCRs).

Steel Product EPDs in Australia: Where are we?

Steel is a cornerstone of Australia's building, infrastructure, and manufacturing sectors. Despite the country's well-established steel industry, a gap persists between local production and total consumption, necessitating substantial imports. In 2023, Australia’s net import of steel products exceeded 1 million tonnes, accounting for approximately 15% of total consumption. While steel plays an essential role in modern construction, it is also a major contributor to embodied carbon in the built environment. This makes accurate carbon measurement of steel products—especially imported materials—a crucial aspect of sustainable construction practices in Australia. Without reliable data, project teams may struggle to assess and mitigate the environmental impact of their material choices.

The Landscape of Concrete EPDs in Australia and New Zealand

Environmental Product Declarations (EPDs) have become an essential tool in the Australian construction industry, particularly within the concrete sector. As sustainability and carbon reduction efforts gain traction, EPDs provide a standardised way to assess and compare the environmental impact of different concrete products. This article explores the current state of concrete EPDs in Australia and New Zealand, including the number of registered EPDs, the leading suppliers, and their role in sustainable construction.

Understanding EPDs in the Australian Construction Industry: Benefits, Content, and Challenges

An Environmental Product Declaration (EPD) is a standardised document that provides transparent, verified information about the environmental impact of a product throughout its lifecycle. It is based on the principles of Life Cycle Assessment (LCA) and follows international standards such as ISO 14025 and EN 15804. In Australia, EPDs are increasingly important in the construction industry, helping architects, engineers, contractors, and developers select materials with lower environmental footprints, supporting sustainable building practices, and complying with regulatory requirements such as the National Construction Code (NCC) and Green Star rating system.

The Data Quality Dilemma in Embodied Carbon Accounting

Embodied carbon makes up 16% of Australia’s built environment emissions, but this number could rise to 85% as operational energy efficiency improves, making its accurate measurement critical for achieving climate goals. Yet, there are key issues with the prevailing methods of calculating these emissions, which may undermine sustainable building practices and hinder the transition towards a decarbonised built environment.
