Indonesia: Norway-based Norges Bank has placed Semen Tonasa under observation for risk of damage to art in Leang Leang Maros Prehistoric Park in South Sulawesi. Reuters has reported that the cement producer has no monitoring system in place for its limestone mining operations near to the designated UNESCO Global Geopark. Vibrations and dust reportedly present a danger to the 44,000yr-old works of art at the site. Norges Bank holds a 1.6% stake in Semen Tonasa's parent company Semen Indonesia.

Norges Bank said "The background for the decision is the unacceptable risk of damage to prehistoric and irreplaceable culture heritage."

Peru: Cemento Gloria subsidiary Cemento Yura's Yura cement plant has allegedly been the source of intermittent dust emissions, water contamination and destructive vibrations during its 50 years of operation. In May 2022, local authorities declared four houses uninhabitable due to cracks in walls and roof collapses. Local people have attributed the damage to the vibrations from the Yura cement plant's activities. In November 2022, local water supply is unavailable for over 40 minutes every day, allegedly also due to the plant's operations.

The La República newspaper has reported that Yura residents have launched a protest against the alleged environmental mismanagement outside of the company's plant.
