Japan: Taiheiyo Cement has set an 80% CO₂ reduction target from cement production by 2050. It also plans to reduce its emissions from cement products by 20%. It aims to do this via a variety of means including energy-saving measures, promoting co-processing, lowering the clinker factor of its cement and CO₂ capture technology. The cement producer started a pilot of a chemical absorption method on kiln exhaust gases at its Fujiwara plant in early 2019.

Bangladesh: Shahab Uddin, the Minister for Environment, Forest and Climate Change, says that five cement plants near the Sundarbans mangrove forest region have been granted environmental clearance certification. The plants are Meghna Cement Mills, Bashundhara Cement Mills, Mongla Cement Mills, Dubai-Bangla Cement Mills and Holcim (Bangladesh), according to the New Nation newspaper. Uddin said that the units were all at least 6km away from the Sundarbans reserved forest area and that the Department of Environment was monitoring their emissions on a regular basis. In 1995 the government declared a 10km area around the Sundarbans Reserve Forest as a ‘critical’ ecological zone.

India: Minister Piyush Goyal, the Commerce and Industry Minister, has confirmed that the Competition Commission of India looking into complaints of rising cement prices. He said that complaints on the had been received about the price of cement and allegations of cartel-like behaviour, according to the New Indian Express newspaper.

US: Researchers from CalPortland have published a peer-reviewed study looking at the absorption or carbonation of CO₂ by buildings, pavements and structures made from concrete. The authors argue that this negative effect on CO₂ emissions is not being considered in global, national and regional greenhouse gas accounting methods. The paper calls for focused studies on CO₂ uptake in concrete within the context of its overall Life Cycle Assessment (LCA).

“It is time to further examine the value of concrete in the built environment as a significant carbon sink,” said Allen Hamblen, president and chief executive officer (CEO) of CalPortland. “To do so accurately, we must specifically look at the net effects of CO₂ sequestration in concrete and evaluate all structures over their lifetime within a circular economy.”

The study looks at previous attempts to quantify the effect of concrete carbonation, notably using work by the Swedish Environmental Research Institute (SERI) that examined data from several European countries to develop practical models to gauge the extent of CO₂ uptake by concrete globally in the built environment. Different models estimated that 15 - 20% of CO₂ emissions from clinker production were reabsorbed over the lifetime of concrete structures.

France: HeidelbergCement France has finalised the acquisition of Cemex’s Centre region aggregates and ready-mixed concrete businesses. The acquisition includes seven aggregate quarries and 28 ready-mixed concrete plants. The acquired aggregates reserves and resources amount to about 25Mt. HeidelbergCement France will fully integrate the operations into its own network.

“With this acquisition, we strengthen our vertically integrated market position in central France,” said Bernd Scheifele, chairman of the managing board of HeidelbergCement. “The operations fit very well into our existing network of aggregates and ready-mixed concrete plants in the Paris region, and we expect significant synergies.”
