What is the Environmental Sustainability Charter (ESC)?

Established in conjunction with the Green Building Council of Australia (GBCA), ASI’s ESC is a certification scheme to assess and identify sustainable steelwork suppliers against industry best practice for environmentally sustainable operations in steel processing.

The Charter is designed for steelwork fabricators, steelwork processors and contractors to demonstrate the company’s commitment to, and continual improvement in environmental management through their in-house steel processing operations. The Charter specifies the implementation of an environmental management policy and communication framework as well as projects that continually reduce the company’s carbon footprint through initiatives such as energy efficiency, scrap management and recycling and capital upgrades. 

Performance is documented through an environmental management system (EMS) which is verified annually by a third-party auditor and certified against best industry practice to a level of performance under the Charter. 

A GBCA project can gain a point towards its Green Star As Built rating by using an ESC-certified steelwork fabricator (ref. GBCA Mat-5). 

For further information on gaining points towards GBCA's Green Star rating, refer to the ESC information sheet

State Authorities, regulators, engineers, builders, environmental rating agencies, and any other contractor looking for a steelwork supplier can be assured that ESC certified companies are complying to environmentally sustainable practices in their steelwork operations as assessed against industry best practice.
