OUR STANDARDS

Steel is a vital material for the built environment and vehicles, art, medicine, and information technology. The steel industry contributes $11 billion to Australia’s GDP and employs over 100,000 people. The unique physical properties of this popular material allow it to be reused or recycled without loss of quality. However, like all materials, steel can pose a significant environmental, health and social burden during its manufacture, use and disposal.

For example, steel manufacturing is a significant contributor to worldwide carbon emissions. In 2020, every tonne of steel, on average, led to the emission of 1.851 tonnes of carbon into the atmosphere. In 2020, 1,860 million tonnes (Mt) of steel were produced, and total direct emissions from the sector represented between 7% and 9% of global carbon emissions.

The extraction of raw materials can also result in a wide range of environmental issues, including threatening biodiversity and ecosystems in adjacent areas, erosion in coastal and riverbanks, or pollution of waterways. Local impacts may include noise and dust pollution, and landscape damage.

Steel manufacturing processes can result in the emission of significant amounts of pollutants, including dioxins, polychlorinated biphenyls (PCBs), nitrogen oxides (NOx), sulphur oxides (SOx) and particulate matter. High levels of nitrogen dioxide, for example, are harmful to vegetation – damaging foliage, decreasing growth or reducing crop yields. Nitrogen oxides and sulphur dioxide can also react with substances in the atmosphere to form acid rain. PCBs are a group of harmful, persistent organic pollutants that are toxic, persist in the environment and animals and bioaccumulate through the food chain.

Toxic heavy metals and their compounds such as mercury, arsenic, selenium, cobalt, tin and antimony are also detrimental to the health of manufacturing staff and users of the finished product. Volatile organic compounds (VOCs) are also present in the coatings of many products. They can trigger allergic reactions, headaches, eye irritation, and asthma problems.

GECA certification removes doubt and confusion and makes identifying environmentally and socially preferable products easier. Products certified under this standard can also contribute toward achieving credit points for projects being certified under the Green Building Council of Australia’s Green Star Performance tool. In addition, our standard is also recognised by the ISC IS rating scheme.
