Switzerland: Indonesian citizens of Pulau Pari have launched a legal case against Holcim in Switzerland for its contribution to climate change. Holcim operated in Indonesia from 1971 through its subsidiary Holcim Indonesia, which Semen Indonesia acquired from the group in 2019. Pulau Pari faces increased climate change-induced flooding, including two floods in 2020. Four residents have launched the present case against Holcim for damages, funding for flood defences and positive measures towards further group CO₂ emissions reduction. Indonesia-based environmental organisation Walhi, Swiss Church Aid (HEKS) and the European Center for Constitutional and Human Rights (ECCHR) are supporting the case.

Japan: Taiheiyo Cement has partnered with JFE Steel and the Global Institute for Environmental Technology to develop a carbon capture and storage system. The system will use wet alkaline earth metals extracted from steel slag to produce carbonates from exhaust gases at cement and steel plants. The partners are investigating the possibility of using these carbonates, specifically calcium carbonate and magnesium carbonate, as additives in cement production at Taiheiyo Cement’s plants. Taiheiyo Cement president Masafumi Shigehara said, “With the effects of climate change becoming apparent both in Japan and overseas, the importance of global warming counter-measures is increasing.”

Mexico: Cemex has announced a new Climate Action strategy, which outlines the company’s vision to advance towards a carbon-neutral economy and to address society’s increasing demands more efficiently. The company states that it believes climate change to be one of the biggest challenges of our time and support collective action.

It says that it has already reduced its net specific CO2 emissions by more than 22% compared to its 1990 baseline. It has now defined a more ambitious target of a 35% reduction of net specific CO2 emissions by 2030. This new goal is aligned with the Science-Based Targets methodology, a requirement that is necessary to meet the goals of the Paris Agreement. To complement this strategy with a longer-term vision, Cemex is also establishing a new ambition to deliver net-zero CO2 concrete by 2050.

“Climate change has been a priority for Cemex for many years,” said Fernando A Gonzalez, Cemex CEO. “Our efforts have brought significant progress to date, but we must do more. This is why we have defined a more ambitious strategy to reduce CO2 emissions by 2030 and to deliver net-zero CO2 concrete by 2050.”

To fulfil this strategy, Cemex has a laid out a CO2 roadmap to accelerate the roll-out of proven technologies across its facilities, including investing in energy efficiency, using alternative fuels, expanding the use of renewable energy, and increasing the substitution of clinker with alternative cementitious materials. It says its aim of net-zero CO2 concrete will require open innovation that requires strategic partnerships and cross-industry collaboration in the development of breakthrough technologies like CO2 capture, storage and utilisation, novel clinkers with low heat consumption, alternative decarbonated raw materials, carbonation of concrete waste for use as recycled aggregates, and the promotion of circular economy models that transform waste into fuel.
