AI Article Synopsis
- The study used the GDIM method to analyze carbon emissions in China's iron and steel industry from 2001 to 2020 and employed Monte Carlo simulation for predictions from 2021 to 2035.
- It found that economic output and crude steel production were the main drivers of carbon emissions, while the reduction in carbon intensity of economic output had the most significant impact on decreasing emissions.
- Projections indicated that emissions could peak in 2030, 2025, and 2020 under different scenarios labeled BAU, L, and S, respectively.
Article Abstract
To explore the future carbon emission peak scenarios of China's iron and steel industry as well as the effective pathways for carbon emission neutrality, the generalized Divisia index method （GDIM） was first used to analyze the influencing factors of carbon emission changes from 2001 to 2020, and then Monte Carlo simulation was used to conduct a dynamic scenario simulation of the carbon emission evolution trends from 2021 to 2035. The results showed that： ① Economic output and crude steel production were the most important factors contributing to the increase in carbon emission in the iron and steel industry； among the factors contributing to the decrease, the carbon intensity of economic output had the most significant effect, followed by the carbon intensity of production, and the energy consumption per ton of steel and the energy output rate did not have a significant effect on the decrease in carbon emissions. ② Under the scenario BAU, scenario L, and scenario S, the iron and steel industry could achieve carbon emission peaking in 2030, 2025, and 2020, respectively.

The pressing necessity to mitigate climate change and decrease greenhouse gas emissions has driven the advancement of heterostructure-based photocatalysts for effective CO₂ reduction. This study introduces a novel heterojunction photocatalyst formed by integrating potassium-doped polymeric carbon nitride (KPCN) with metallic Zn₃N₂, synthesized via a microwave-assisted molten salt method. The resulting Schottky contact effectively suppresses the reverse diffusion of electrons, achieving spatial separation of photogenerated charges and prolonging their lifetime, which significantly enhances photocatalytic activity and efficiency.

Changing land use is one of the main factors influencing global climate change and the imbalance in the carbon cycle. Consequently, the focus of international organizations and the academic community is on strategies to mitigate carbon emissions or improve carbon sequestration by optimizing land use structure and function. Since 2019, China's Zhejiang Province has implemented a township-level pilot policy, exploring a comprehensive land consolidation (CLC for short) pilot policy that includes all elements of "mountains, rivers, forests, farmlands, lakes, and grasslands.

Most ocean plastics originate from terrestrial emissions, and the plastisphere on the plastics would alter during the traveling due to the significant differences in biological communities between freshwater and marine ecosystems. Microorganisms are influenced by the increasing salinity during traveling. To understand the contribution of plastic on the alteration in biological communities of plastisphere during traveling, this study investigated the alterations in microbial communities on plastics during the migration from freshwater to brackish water and saltwater.
