Abstract This paper, which is a contribution to the UNEP series on Eco-Efficient Cements, examines the role of material-based solutions to reducing CO 2 emissions from cement production considering factors that could influence implementation. Global urbanization has led to an increase in demand for cement and cement-based materials. With its growth in consumption, the associated CO 2 emissions from its production are raising concern. However, the role of mitigation strategies in a global context that account for regional material availability and degree of market adoption have yet to be considered. This work shows that the 2 °C scenario targets for 2050 can be met through increased use of calcined clay and engineered filler with dispersants. The introduction of new Portland clinker-based cement alternatives, use of alkali-activated materials, and improvement of efficiency of cement use could further contribute to reduction goals. There are currently-available technologies for reduction that could be rapidly implemented.

- Technologies and policies to decarbonize global industry: Review and assessment of mitigation drivers through 2070 (2020, background): “available options for reducing clinker content in cement are calcined clays and inert fillers, which will not compromise performance if used appropriately and could reduce annual emissions from the cement sector by over 600 MtCO2 per year if widely adopted [49].”
