According to a 2018 report from U.K. think tank Chatham House, over 4 billion metric tons of cement are produced annually. This milling step produces an "activated" intermediate that contains the constituents of the cement in uniform distribution. intune copy file to user profile. In 2021, worldwide emissions from making cement for buildings, roads and other infrastructure hit nearly 2.9 billion tons (2.6 billion metric tons) of carbon dioxide, which is more than 7% of the global carbon emissions, according to emissions scientist Robbie Andrew of Norways CICERO Center for International Climate Research and the Global Carbon Project. As with industry overall, the decarbonisation of cement will require multiple measures, including: Greater uptake of alternative fuels can be facilitated by redirecting waste from landfills to the cement industry and by coordinating the supply of sustainably sourced biomass across sectors to enable cost-competitive access for cement production. Other programmes target innovation, such as the GCCA's Innovandi programmes. A less common form of cement is non-hydraulic cement, such as slaked lime (calcium oxide mixed with water), which hardens by carbonation in contact with carbon dioxide, which is present in the air (~ 412 vol. More importantly, bypassing lime calcination could ideally avoid CO2 emissions in the gigaton range. The European Union is in the process of developing a carbon border adjustment mechanism for industries, including cement, which would apply tariffs on emissions-intensive goods from foreign jurisdictions with weak or absent emissions policy in an effort to limit carbon leakage and incentivise stronger emissions measures in foreign countries.
