The calcination of calcium carbonate, the clinkerization process and the burning of fossil fuels when manufacturing cement are the main culprits of the high CO2 emissions by the cement sector. CO2 is known for being the main greenhouse gas (GHG) and there are growing concerns both nationally and internationally about reducing its emissions. Research on technologies aimed at reducing GHG emissions during the cement manufacturing process can be found in the scientific literature, and include mineral addition, clinker-free cement (or with low clinker content), kiln efficiency, carbon capture, use of raw materials and alternative fuels, among others. The aim of this research was to present a bibliometric analysis of studies on alternatives to reduce greenhouse gas emissions and substitute the use of clinker or cement internationally. The research was based on scientific papers published in renowned journals from 2007 to 2017. Keywords related to CO2 emissions from clinker and cement production were searched for within the vast sustainability area in the Scopus database. The search comprised data on the type of solutions adopted for reducing emissions, the country where the study was conducted, and the number of publications per year and per journal. With the results of this research in hand, the amount of publications from each country was matched with their GHG emission levels. According to the authors, the sustainability of the cement sector depends on reducing kiln energy consumption and clinker consumption in cement, or using less cement in concrete. Moreover, the most widely analyzed impact categories were energy consumption and CO2 emissions, despite the likelihood of other categories having even greater impacts.
