Abstract
Assessing historical emission trajectories and forecasting future changes at the unit level for the global cement industry are vital for summarizing past experiences in green management and designing a plant-by-plant transition roadmap. Here, we evaluate the evolution of major air pollutant emissions during 1990−2020 and explore mitigation pathways for future sustainable development, based on a developed unit-level global cement emissions database. Our findings indicate that strengthening emission standards is an effective strategy for decoupling air pollutant emissions from clinker production, particularly for emerging economies. Without stringent emission controls, these economies contributed to 49.1%, 39.8% and 74.1% of SO2, NOx, and PM2.5 emissions in 2020. With stricter standards, emerging economies can achieve a 0.6 Mt NOx emission reduction despite a 70% growth in cement demand from 2020 to 2060. By deepening mitigation efforts, China and developed countries can reduce NOx and PM2.5 emissions by 1.4 and 0.9 Mt, respectively, by 2030.
期刊介绍:
The journal Resources, Conservation & Recycling welcomes contributions from research, which consider sustainable management and conservation of resources. The journal prioritizes understanding the transformation processes crucial for transitioning toward more sustainable production and consumption systems. It highlights technological, economic, institutional, and policy aspects related to specific resource management practices such as conservation, recycling, and resource substitution, as well as broader strategies like improving resource productivity and restructuring production and consumption patterns.
Contributions may address regional, national, or international scales and can range from individual resources or technologies to entire sectors or systems. Authors are encouraged to explore scientific and methodological issues alongside practical, environmental, and economic implications. However, manuscripts focusing solely on laboratory experiments without discussing their broader implications will not be considered for publication in the journal.
