Carbon dioxide emissions from cement production have doubled in the last 20 years, according to emissions scientist Robbie Andrew of Norway’s Centre for International Climate and Environmental Research (CICERO).
Global emissions from making cement for buildings, roads, and other infrastructure reached almost 2.9 billion tonnes of carbon dioxide in 2021, accounting for more than 7% of global carbon emissions. Back in 2002, cement emissions only totaled 1.4 billion tonnes.
