A review and perspective on industry high-temperature heat pumps

Jiatong Jiang et al.

Summary: This study proposes future development directions for High-temperature Heat Pumps (HTHPs) based on laboratory-scale research and application cases. The study emphasizes the use of low Global Warming Potential (GWP) refrigerants in laboratory research, while high-GWP refrigerants are dominant in applications. The suggested prospects for future development include the use of low-GWP refrigerants, higher output temperatures, larger heating capacities, and higher Coefficients of Potential (COP).

Towards carbon neutrality with Chinese characteristics: From an integrated perspective of economic growth-equity-environment

Hao Chen et al.

Summary: With climate warming becoming increasingly severe, reducing carbon emissions has become a global consensus. However, the process of carbon emission reduction entails changes in economic, industrial, and energy structures, thereby affecting economic output, employment, and overall social welfare and equity. Therefore, it is crucial for every nation to determine a scientifically and effectively carbon emission pathway that considers both social development and climate targets. As the largest carbon emitter, China has set carbon peak and carbon neutrality targets. This paper designs corresponding carbon emission reduction scenarios based on China's new emission reduction situation. Additionally, an optimization model integrating economic growth, equity, and environment is developed to determine China's emission pathways from 2020 to 2050 while maximizing social welfare. The results quantitatively demonstrate future total amounts and peak values of carbon emissions under different scenarios, as well as their evolution over time. In most scenarios, the peak concentration will occur between 2025 and 2030, reaching approximately 10.7 to 11.8 billion tons. As carbon emission reduction constraints become more stringent, the cost of reduction will increase, although overall social welfare will slightly increase. Finally, the findings of this study provide practical guidance for achieving carbon emission reduction and offer insights for policymaking.

Paris climate agreement and global environmental efficiency: New evidence from fuzzy regression discontinuity design

Muhammad Salman et al.

Summary: This study evaluates the impact of the Paris Agreement on environmental efficiency and greenhouse gas emissions in 162 countries from 1990 to 2020. Results indicate that developed countries have improved environmental efficiency due to technological progress, while developing countries and least developed countries have experienced declines. The policy intervention of the Paris Agreement has reduced greenhouse gas emissions and improved global environmental efficiency, but the effects vary among countries, with developed countries benefiting more.
