In response to our role in reducing Aotearoa New Zealand’s carbon emissions – we’re in the process of developing the world’s first comprehensive steel product offset calculator.

This is part of our steel product carbon offset program – Tātaitai Puhanga Waro (mo te Hua Rino), which has been developed to provide a robust carbon offsetting program for steel products in New Zealand.

Reducing the steel industry’s emissions is a big challenge. This is because carbon is primarily used in the steel making process as a reductant (rather than a fuel). And currently, no commercially viable alternative exists for coal as the reductant in steel making.

Until such an alternative is developed, it is important for the industry to utilise carbon offsetting as a mechanism to reduce net emissions.


How it works

  1. Emissions for most steel products used in New Zealand will be calculated using our online calculator [1] once up and running;
  2. Emissions can then be offset via Ekos through the calculator itself. It has a requirement for the offsets to be focused on the planting and protection of native forests which in turn provides additional biodiversity and human capital benefits; and
  3. Ekos will send a receipt and certificate via email to show that emissions for a particular project/product have been offset.


Why will this program be trustworthy and credible?

  • It will be based on science!
    The core offsetting calculations in this program are based on life cycle assessment (LCA) and environmental product declarations (EPDs). This means the data is publicly available and peer-reviewed, and calculated in a consistent and comparable way across products.
  • Independence
    In consultation with us, the program rules are being developed by independent sustainability advisors at thinkstep-anz. HERA, as an independent research association, has no vested interest in supporting one steel product, supplier or manufacturer above another.
  • Offsets that are trustworthy and have broader sustainability benefits
    Ekos is a New Zealand social enterprise that grows and protects indigenous forests, developing sustainable development outcomes in rural communities. Ekos’s carbon credits arise from establishing new forests and protecting existing forests indefinitely from logging. These conservation activities create measured, reported and verified carbon benefits. Ekos is recognised as a credible carbon offsetting scheme by ConsumerNZ[2].

HERA Position Report for the SSC – Steel’s contribution to a circular economy and low carbon future

Our social licence to operate is fundamental to the long-term sustainability of the steel industry in New Zealand. Steel is the backbone to our cities – it is what makes them resilient to climatic and seismic conditions that are prevalent in Aotearoa.

Kiwi’s want reduced co2 emissions, increased recycling and improved productivity – with less impact on our environment.

Steel is at the heart of solving these challenges.
