Concrete production contributes to 8% of global annual carbon emissions. With the size of Paris being built globally every single week for the next 40 years, the demand for concrete is significant. The concrete industry becoming net zero is vital to halving carbon emissions by 2030 and limiting global temperature rise to 1.5C.

The founding ConcreteZero members are signalling to the industry the scale of demand for sustainably produced and sourced concrete. But to accelerate progress, businesses need a globally agreed definition on what is considered net zero and low emission concrete. ConcreteZero members are breaking down this barrier by making a commitment to measure and report on the carbon emissions associated with the concrete they use. This data will enable the industry to set a global standard of what low emission and net zero concrete is, bringing a clear signal to suppliers and policymakers.  

Jen Carson, Head of Industry of Climate Group, said: “It’s time for concrete targets to reduce carbon emissions in years not decades. ConcreteZero is signalling to the industry that the biggest buyers want the industry to innovate and act now on emissions. Concrete and steel emit as much as all road transport globally, and demand is going up. We won’t address the climate crisis without big bold measures on industry.”

At Ramboll we are all in on sustainability, our strategy “The Partner for Sustainable Change” underlines our ambition to drive sustainable change for both clients and society. As one of ConcreteZero’s founding members, we are helping accelerate this bold initiative, to build a more sustainable future.

Philippa Spence, Ramboll Managing Director, UK, said: “This fantastic initiative is a very important and vital step in the decarbonisation of our built environment. The impetus to deliver an impact fast, through collective industry effort and baseline concrete carbon reporting will prove essential for our net zero future.” 

Concrete, a mix of cement, gravel, sand and water, is a final consumer product. The chemical process used to make traditional limestone cement is very energy intensive, emitting significant levels of CO2. Inclusion of cement in the concrete mix drastically increases the level of carbon emissions associated with the end product. By focusing on concrete, Climate Group is maximising all the opportunities in the production of concrete, to cut carbon emissions.

ConcreteZero builds on Climate Group’s highly successful demand-side climate initiatives which already have the scale of a G7 country on renewable electricity and 5 million electric vehicles.
