What percentage of global CO2 emissions come from cement production?

The cement industry is responsible for approximately 7% of global greenhouse gas emissions[1]. Other estimates indicate that the steel and cement sectors combined account for 14% of global CO2 emissions[2], while another source notes that cement production specifically accounts for about 5% of annual global anthropogenic carbon dioxide emissions[3].

The following table summarizes the reported contributions of the cement industry to global emissions:
