Cement and concrete net zero roadmap

Cement and concrete net zero roadmap

Global cement and concrete industry announces Roadmap to achieve groundbreaking 'Net Zero' CO2 emissions by 2050.

Forty of the world’s leading cement and concrete manufacturers have joined forces to accelerate the shift to greener concrete by pledging to cut CO2 emissions by a further 25% by 2030, marking a decisive step in the race to ‘Net Zero’ concrete by 2050.

The move by the members of the Global Cement and Concrete Association (GCCA) marks the biggest global commitment by an industry to net zero so far – bringing together companies from the Americas, Africa, Asia, including India and China, and Europe. It follows the September announcement during New York Climate Week that the GCCA has become the first global ‘heavy’ industry accelerator for the UN’s global Race to Zero. GCCA members account for 80% of the global cement industry volume outside of China, and also include several large Chinese manufacturers.

The GCCA has published a detailed roadmap which sets out the path that the industry will follow to fully decarbonize by 2050, a target aligned with the Paris Agreement to limit global warming to 1.5°C. The roadmap actions between now and 2030 will prevent almost 5 billion tonnes of carbon1 from entering the atmosphere compared to a business-as-usual scenario, equivalent to the CO2 emissions of almost 15 billion passenger flights from Paris to New York2.

Concrete is the most used human-made material on the planet with 14 billion cubic meters3 produced every year for use in everything from roads to bridges, tunnels to homes, and hydropower installations to flood defenses. Concrete is an essential element of construction, with no other material equaling its resilience, strength and wide availability. Production of cement, the key ingredient in concrete, accounts for around 7% of global CO2 emissions. The new 2030 commitment by the GCCA outlines a significant acceleration in the pace of industry decarbonization.

The roadmap to get there is built around a seven-point plan that relies on ambitious yet achievable actions to reduce the amount of CO2 intensive clinker in cement, significantly reduce fossil fuel use in manufacturing, and accelerate innovation in products, process efficiency and breakthrough technologies including carbon capture.

While the GCCA has outlined an ambitious programme for its members, it also calls on governments, designers and contractors to fully play their part by assembling the right public policies and investments to support the global scale transition of the industry. These include greater development of critical technologies such as carbon capture and storage, and reforms to public works procurement policy to encourage the use of low-carbon cement and concrete products. Public policy reforms and the promotion of low carbon products can make a big difference as public infrastructure accounts for almost 60% of all global cement and concrete demand.

Thomas Guillot, GCCA Chief Executive, said: “Concrete is the world’s most used building material and provides the foundation for renewable energy transition, resilient infrastructure and new homes around the world.”

He added: “Global cooperation on decarbonizing concrete is a necessity, as countries developing their infrastructure and housing will be the biggest users of concrete in the coming decades. I am proud of the commitment made by our members today to take decisive action and accelerate industry decarbonization between now and 2030, an important milestone towards the ultimate goal of net zero concrete. I envision a world in the not too distant future where the foundation of a sustainable, zero carbon global economy will literally be built with green concrete.

“We now need governments around the world to work with us and use their huge procurement power to advocate for low carbon concrete in their infrastructure and housing needs. We require their support to change regulation that limits the use of recycled materials and impedes the transition to a low carbon and circular economy,” said Mr Guillot.
