Turkish cement maker Cimsa cuts emissions via renewable energy push

Turkey's major cement producer Cimsa has reduced the Scope 1 and Scope 2 emission intensity for its products by 17% compared to the 2021 base year through renewable energy investments, the company said in its integrated activity report published March 30.

"This progress demonstrates the effectiveness of our decarbonization transition plan and the feasibility of the outlined roadmap," it said.

While aiming to increasingly meet our energy needs from sustainable and renewable sources, we prioritize practices that strengthen our energy independence, provide cost stability and manage climate-related risks, Cimsa said.

Noting that the use of alternative fuel is an important element of Cimsa's energy transformation and decarbonization strategy, the company said it has already made strong, determined progress in its fuel conversion strategy by increasing its alternative fuel usage rate in grey cement from 13% in 2021 to 28% in 2025.

"As Cimsa, we consider Carbon Capture, Utilization and Storage (CCUS) technologies as a strategic solution area in our journey towards our long-term net zero target," the company said.

Cimsa aims to reduce overall gross Scope 1 and Scope 2 greenhouse gas emissions per ton of cement product by 42.1% from the base year of 2021, through new renewable energy investments, until 2033.

Cimsa carries out its production activities with three integrated cement factories located in Mersin, Eskisehir and Afyonkarahisar in Turkey and the Bunol White Cement Factory in Valencia, Spain.

The company's new grey cement grinding plant investment, with an annual average grinding capacity of 600,000 metric ton/year, carried out within its subsidiary Cimsa Americas operating in Houston, US, was also commissioned in October 2025 following the successful completion of test productions.

Cimsa is one of the world's foremost brands in white cement and one of the world's top three producers of CAC (calcium aluminate cement).

The Platts assessment for ordinary Portland cement (CEM I 42.5R) (bulk) was at $54.75/mt CEMDEX Turkey on March 26, while the assessment for Cement clinker (OPC grey clinker) was at $45.75/mt, both up 25 cents/mt week over week.
