Accounting process-related CO₂ emissions from global cement production under Shared Socioeconomic Pathways

Cement production is the main source of industrial process-related CO₂ emissions, taking up approximately half of total industrial process-related CO₂ emissions. However, limited research has investigated the process-related CO₂ emissions from global cement production, in particular, has not taken into account the impacts of dynamic socio-economic development context. This study aims to explore the trajectory of industrial process-related CO₂ emissions in the cement industry under different Shared Socioeconomic Pathways (SSPs), to provide more evidence for the existing climate change integrated assessment analysis. By investigating the relationship between per capita GDP and per capita cement production process-related CO₂ emissions drawing on the historical data during 1950–2014 in 31 developed countries, the cement production process-related CO₂ emissions from 175 countries in 12 regions in the world during 2015–2100 under five SSP scenarios are given here. The results show that the largest amount of global cumulative cement process-related CO₂ emissions would be 45.45 billion tons under SSP3 scenario. The countries that contribute the most to the global cumulative cement production process-related CO₂ emissions from 2015 to 2100 are India, China, Nigeria, United States of America and Pakistan.
