Leading cement producers

China was by far the leading cement producing country in 2025, with production reaching nearly *** billion metric tons. India ranked a distant second that year, producing *** million metric tons. Unsurprisingly, Chinese and Indian firms are among the leading cement manufacturers in terms of revenue, however the Swiss based company Holcim topped the list in 2024. 

Cement industry emissions

The production of cement requires the heating of a mixture of minerals to temperatures of more than 1400 degrees Celsius in a kiln. This step requires vast amounts of energy, which makes cement production one of the leading causes of greenhouse gas emissions worldwide. Carbon dioxide emissions from cement production have increased nearly continuously for several decades, reaching **** billion metric tons in 2024.
