World Economic Forum and GCCA report identifies the countries that are prioritising green public procurement
24 June 2022UK: The World Economic Forum and the Global Cement and Concrete Association (GCCA), in collaboration with Boston Consulting Group (BCG), have released a Mission Possible Partnership Report which identifies the nations that are prioritising green public procurement. These are the Netherlands, Sweden, Germany, France, the UK, and select US states. The report titled ‘Low-Carbon Concrete and Construction - A Review of Green Public Procurement Programmes’ identifies a framework for how these six countries are demonstrating leadership in green public procurement of concrete and construction.
The first component of the framework is the foundation, which includes establishing standards for reporting emissions, databases and tools for tracking emissions and establishes baselines. The second part of the framework, procurement polices, builds upon and reinforces the foundation by setting policies that require environmental disclosures, mandate carbon limits, and incentivise low-carbon design, and use of low-carbon materials.
Approximately 7% of global carbon emissions come from cement, and about half of the cement used globally is procured by the public sector. Governments also spend US$11tn/yr on procurement, about 12% of global gross domestic product (GDP) and regulate the construction industry via building codes. Therefore, governments play a critical role in driving demand to decarbonise the concrete and construction sector to achieve net zero goals.
Matt Rogers, the chief executive officer of the Mission Possible Project said “The demand signals in the market for green industrial products are among the most important opportunities to accelerate the path to net zero across industrial sectors. For material sectors like cement and concrete, government procurement practices will play an especially important role. This report summarises the current best practices in government procurement for green cement across multiple markets. Insights like these provide the government procurement professionals practical tools and technical insights that they can use today to create demand-pull for the most innovative low carbon cement and concrete offerings in the market.”
PCA opposes pause to US petrol tax
24 June 2022US: The Portland Cement Association (PCA) has opposed a proposed federal temporary suspension to a petrol tax. PCA president and chief executive officer (CEO) Mike Ireland said, “Pausing the federal gas tax is the wrong decision at the wrong moment. Gas tax revenues fund the Infrastructure Investment and Jobs Act (IIJA), which is a once-in-a-lifetime opportunity to remake American industry and infrastructure with sustainability at its core. Removing the funding from the gas tax will strangle the IIJA before it is even up and running.”
The passage of the IIJA has coincided with PCA's launch of its Roadmap to Carbon Neutrality, which outlines the steps needed to achieve carbon neutrality across the entire cement-concrete-construction value chain by 2050. The PCA says that implementing the changes in its roadmap will require ‘significant’ funding such as those generated from the petrol tax.
US: Sweden-based Bruks Siwertell has commissioned a Siwertell 490 F-type ship unloader at Colonial Group’s Georgia Kaolin Terminals in Savannah, Georgia. The unloader has a rated cement handling capacity of 800t/hr, discharging vessels of up to 55,000dwt.
Eco Material Technologies opens pozzolan mine
23 June 2022US: Eco Material Technologies, a producer of sustainable cementitious materials, has opened its Kirkland Pozzolan Mine in Yavapai County, Arizona. The 40-hectare site is one of the largest natural pozzolan mines in the US.

DG Khan Cement to start exporting cement to the US
15 June 2022Pakistan: DG Khan Cement Company is ready to export 50,000t of cement to the US following a certification process. The Tomini Felicity bulk carrier was reportedly being loaded at the Port of Karachi in mid-June 2022 for shipping to Houston in Texas, according to the News International newspaper. The transport is part of a 100,000t deal with a US-based company that was arranged in mid-2021. The intervening period has been spent arranging the necessary certificates. The export is believed to be the first time a Pakistan-based producer has sent cement to the US.
Canada/US: Holcim North America has invested in Blue Planet to support the development and commercialisation of its mineralisation technology. Blue Planet’s process sequesters CO2 with building waste feedstock such as recycled concrete, cement kiln dust (CKD) and slag to produce new aggregate products. Each tonne of Blue Planet’s aggregate can mineralize up to 440kg of captured CO2. Lafarge Canada, Holcim US, and Blue Planet will start a multi-year collaboration to help identify potential to use the mineralisation technology to further lower the carbon footprint of the companies’ cement, aggregates and concrete operations, with the potential to expand to other operations in the Holcim Group around the world.
“This is an important step for us in North America. Our vision is to transform our St Constant Plant in Montreal into a carbon campus that ultimately advances commercialisation of mineralisation technologies, including Blue Planet’s products,” said David Redfern, president and chief executive officer, Lafarge Canada. “We look forward to advancing our Net Zero strategy by leveraging mineralization technology that allows us to use the CO2 from our own cement plants to produce carbon neutral or carbon negative sand and gravel products.”
US: The Global Cement and Concrete Association (GCCA) hosted chief executive officers (CEO)from across the global cement industry at its CEO Gathering in Atlanta, Georgia, on 9 June 2022. The event explored the best ways for the sector to progress towards net zero CO2 emissions. Speakers included: UN special advisor on climate Selwin Hart, US Department of Energy assistant secretary for fossil energy and carbon management in the Brad Crabtree, architecture firm Gensler CEO Diane Hoskins, Chair of Oil and Gas Climate Initiative (OGCI) executive chair Bjorn Otto and climate economist Gernot Wagner.
GCCA CEO Thomas Guillot said “To achieve net zero and enable the delivery of the sustainable built environment of the future, there needs to be ongoing engagement and deeper collaboration between our industry and government in the years ahead. Targeted government policy will be vital to removing barriers and to expediting our industry’s decarbonisation plans.”
