The use of concrete in Australian building structures exceeds 13 million tonnes per year and its impact on the environment is considerable. With 5% of total CO2 emissions coming from cement production, one of the main components of concrete, it is imperative that Australian standards produce efficient design solutions. Preliminary modelling shows that a minimum 5% efficiency gain is possible through a re-evaluation of reliability indices with contemporary construction practices and materials, giving an immediate 180,000 tonne per annum reduction in carbon emissions. Added to this are savings through reduced transport and reduced water, sand and aggregate consumption, the potential saving on the environment, and economy, are considerable.

澳大利亚建筑结构中混凝土的使用量每年超过1300万吨，对环境的影响相当大。水泥生产是混凝土的主要成分之一，其二氧化碳排放量占总排放量的5%，因此澳大利亚标准必须制定高效的设计解决方案。初步建模表明，通过对现代建筑实践和材料的可靠性指标进行重新评估，至少可以提高5%的效率，每年可立即减少180，000吨碳排放。除此之外，通过减少运输和减少水、砂和骨料消耗，还可以节省大量的费用，从而节省环境和经济方面的潜在费用。
