US: 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.

Austria: RHI Magnesita says it has released CO₂ emissions data for all of its 200,000 products. Technical Data Sheets now include a field ‘Environmental Indicators’ in which the CO₂ equivalent emission of one metric ton of the product is listed. The calculation method for these indicators is developed with and supervised on an on-going basis by an external organisation under the principles of ISO standards. All greenhouse gases ‘cradle-to-gate’, from raw material extraction to production to packaging to gate are considered in these CO₂ footprint calculations.

Chief sustainability officer Gustavo Franco said "This project marks an important milestone towards a green transformation. Thus, one of RHI Magnesita's main targets is to significantly reduce emissions over the next few decades, with the long-term goal of achieving net-zero operations in all areas of the company. It is clear, that a solid basis for sustainable decisions and developments can only be achieved by creating a valid audited database."

World: The total volume of CO₂ emissions released during cement production have more than doubled over the past 20 years, a study has revealed. In 2021 CO₂ emissions from the manufacture of cement came to 2.6Bnt, more than 7% of all emissions, according to Robbie Andrew, a greenhouse gas emissions scientist at the CICERO Center for Climate Research in Norway and the Global Carbon Project. In 2001 the CO₂ emissions from cement production were just 1.2Bnt.

Driven by China, the global cement sector’s CO₂ emissions have now more than tripled in the 30 years since 1992, recently increasing by 2.6% a year. The drivers are not just that more cement is being made, but that the CO₂ intensity of production has risen by 9.2% per tonne, according to the International Energy Agency. This is due to a switch from production in mature markets to developing ones, with China again a dominant factor.

Canada: Holcim subsidiary Lafarge Canada has announced that its Bath cement plant in Kingston, Ontario, is in the process of converting to the production of Holcim’s OneCem product, a low CO₂ Portland Limestone Cement (PLC) alternative. The plant currently makes general use (GU) cement.

"As the leader in the cement industry in eastern Canada, we are committed to developing our green portfolio and advancing towards a sustainable future, with OneCem as a step on the journey," said Andrew Stewart, Vice President for Cement at Lafarge Eastern Canada.

Robert Cumming, Head of Sustainability & Public Affairs for Eastern Canada, said "From 2018 to 2021 we have saved more than 140,000t of CO₂ by converting GU cement to OneCem in our plants across Ontario, Quebec and Nova Scotia - the equivalent to taking 42,891 cars off the road. With the recent conversion of the Bath Plant's GU production to OneCem, these numbers will continue to grow."
