NZ Concrete Pushing Toward Emissions Target

MONDAY, JUNE 22, 2020


Following an independent review conducted by independent auditor, Australian sustainability consultancy Thinkstep earlier this year, found that Concrete New Zealand is on track to meeting its climate change commitments.

Those commitments were set when the New Zealand government signed the Paris Agreement. The universal, legally binding global climate change agreement sets out a global framework to avoid climate change by limiting global warming to well below 2 degrees Celsius and pursuing efforts to limit it to 1.5 C.

Currently, the company is reported to supply and use roughly 1.5 million tons of cement in the country, which equates to around 4 million cubic meters of concrete for new residential, commercial and infrastructure construction.

However, Thinkstep reports that New Zealand’s concrete industry is already halfway toward its goal of reducing carbon dioxide emissions by 30% by 2030.

“The independent review confirmed that the New Zealand concrete industry has reduced its emissions from cement by 15 percent between 2005 and 2018,” said Concrete New Zealand Chief Executive Rob Gaimster. “The emissions reduction occurred against a 13% increase in demand, which demonstrates how committed we are to sustainability.

“We are pleased that our initiatives to reduce cement’s carbon footprint have avoided about 400,000 tons of carbon dioxide emissions in 2018 alone.”

According to the company, the emission reductions were achieved through a variety of measures, including the use of waste products such as wood biomass and vehicles tires to fuel cement kilns.

Additionally, when sharing the review results with Climate Change Minister Hon James Shaw, the company went over how concrete aims to be apart of the transition to a net zero carbon New Zealand by 2050. In using naturally occurring minerals in the country, the company believes the materials can be used to replace a percentage of cement clinker, which is the main ingredient of concrete production associated with carbon dioxide emissions, in addition to its previously listed initiatives.

Gaimster concluded that, “Waste from other industries can also be used to lower the cement clinker content in concrete and help to significantly reduce concrete’s carbon footprint. At the same time, moving to new technologies, such as more energy efficient equipment and vehicles to produce and transport concrete, is part of our plan to be net carbon neutral by 2050.

“Our industry knows how important concrete is to everyone’s future wellbeing. That’s why we’re working so hard to reduce our carbon footprint and maximize the benefits of concrete.”
