How does Atlas Concrete produce Low Carbon Concrete?
By utilising New Zealand’s lowest carbon cement, sourced from Golden Bay Cement, we significantly reduce the embodied carbon in our concrete. Cement is a major contributor to concrete’s carbon footprint, and our choice of cement ensures a greener product.
Our concrete is mixed at the plant using large electric-powered mixers, a method that enhances material and energy efficiency compared to traditional truck mixing. This approach not only ensures a consistent product but also reduces cement use and carbon emissions. Atlas Concrete is proud to be the only ready-mixed concrete producer in New Zealand to implement this advanced mixing technology across all production sites.
We incorporate BFS (Blast Furnace Slag) and Fly Ash, industrial by-products that not only lower carbon emissions but also enhance the durability of our concrete. Additionally, our commitment to sustainability extends to using up to 50% recycled materials from one of our three aggregate recycling plants, further reducing the demand for virgin resources.
Specifying GreenStone LCC™
Choosing the right GreenStone LCC™ product depends on various factors, including CO2 reduction goals, application requirements, and construction timelines. Our team collaborates closely with designers and builders to select the most appropriate mix, ensuring optimal performance and sustainability. From general use to specialized applications, GreenStone LCC™ offers a range of options to meet diverse construction needs.
Before specifying, call the Atlas Concrete team to discuss and aims of the project.

Environmental data, GWP
Our environmental impact data, including GWP figures for all Atlas Concrete mixes, is derived using the GCCA EPD tool, a leading Life Cycle Analysis tool for the cement and concrete industry. Around 70% of the embodied carbon in concrete is from cement, and our cement supplier Golden Bay has an independently verified EPD that provides the basis for our figures. While we are in the process of obtaining independent verification for our data, our commitment to transparency and quality is clear. Our partnership with Golden Bay Cement, underscores our dedication to providing environmentally responsible concrete solutions. The GCCA EPD tool ensures that all the relevant remaining data for other materials and the production process are included and account for. Once Atlas Concrete receives independent verification on this data we will publish it formally in an EPD.
Our self-declared environmental data, based on rigorous standards and certifications, reflects our ongoing commitment to reducing the environmental impact of our products. By choosing Atlas Concrete and GreenStone LCC™, you are partnering with a leader in sustainable construction, dedicated to advancing low carbon, environmental, and sustainable concrete solutions.
