Code from: The climate benefits from cement carbonation are being overestimated

Achieving rapid decarbonization in the cement industry is essential for meeting climate targets. However, oversimplifying the impact of direct air capture via cement carbonation has hindered setting realistic pathways to meet the desired outcomes of net-zero objectives. Our study outlines the global scale of cement carbonation and its influence on long-term climate impact, including code and data for reproducing our results. This research underscores the significance of the dynamic effects of emissions and carbon uptake on climate change, as well as the variability in expected carbonation due to different model parameters, offering a critical assessment of carbonation's role in cement industry decarbonization strategies., , , ## Code from: The climate benefits from cement carbonation are being overestimated
