What specific carbon accounting framework does Malaysia lack for construction?

Question

Malaysia Lacks a Standardised, Locally Developed Carbon Accounting Framework for Construction

Malaysia's construction sector currently lacks a specific, standardised, and locally developed carbon accounting framework. While listed companies are preparing to publish sustainability reports aligned with the NSRF, the underlying methodology for calculating carbon figures remains inconsistent. This absence extends to a lack of standardised protocols for measuring on-site emissions and no mandated approach for deriving these figures, creating a significant data infrastructure problem.
Absence of a Localised Carbon Accounting Framework

The core issue identified is the absence of a carbon accounting framework tailored to the Malaysian construction industry. This means that while companies are reporting carbon figures, the methods used to generate these numbers are not uniform or specifically adapted to local conditions. This structural problem prevents a consistent understanding of the sector's environmental impact, as two firms with similar operations could report vastly different carbon figures and still be considered compliant due to the lack of a defined standard.
Limitations of Existing Reference Tools

While CIDB's Embodied Carbon Inventory serves as a primary reference, it is described as a foundation rather than a complete mechanism. This inventory aggregates emission factors from various sources, including regional and international data. However, its limited number of material records, approximately 600, across a sector with thousands of specifications means that local data is often unavailable. In such instances, the inventory defaults to international figures, which are calibrated to foreign manufacturing conditions and energy mixes, thus introducing potential inaccuracies for Malaysian contexts.
Gaps in On-Site and Embodied Carbon Measurement

A significant omission in the current reporting landscape is the lack of a standardised quantification mechanism for carbon released from on-site construction activities. Globally, these activities, including fuel combustion from machinery, waste disposal, and temporary works, account for a substantial portion of the construction industry's carbon footprint. Furthermore, the existing framework does not adequately address the full scope of embodied carbon, particularly where local manufacturing data and actual Malaysian grid emission factors are not integrated into the calculations.
Need for a Malaysia-Specific Database and Mandated Standards

To address these shortcomings, there is a clear call for CIDB to develop a Malaysia-specific embodied carbon database. This database should be built upon local manufacturing data, actual Malaysian grid emission factors, and domestically verified supply chain benchmarks. Concurrently, the Securities Commission (SC) Malaysia is urged to move beyond the current reporting template and mandate a minimum carbon calculation standard. This standard should specify permissible emission factors, essential on-site activity categories, and a timeline for transitioning from modelled estimates to primary supplier data, with explicit assurance requirements.
