Summary: The study compares data from 134 countries and finds that developing countries are increasing their carbon emissions rapidly, while emerging developing countries are achieving weak decoupling. In order for developing countries to achieve absolute decoupling, the deteriorating structural and intensity technology drivers need to be addressed.

Summary: This study examines the decoupling state between energy consumption and agricultural economic growth in China's agricultural sector from 2000 to 2019. The results show that at the national level, the decoupling fluctuates among expansive negative decoupling, expansive coupling, and weak decoupling before stabilizing in the weak decoupling state. The decoupling process also varies by geographic region, with strong negative decoupling in North and East China and strong decoupling in Southwest and Northwest China. The study also identifies the driving factors for decoupling, including economic activity, industrial structure, energy intensity, population, and energy structure effects.

Summary: This study applies mathematical models to analyze the interrelationship between agricultural CO2 emission and economic development in China. The research identifies the driving factors and decoupling trend for Chinese agricultural CO2 emission from 1996 to 2020. It is found that agricultural economic development is the primary driving factor for the increase of CO2 emission, while agricultural labor and production efficiency have inhibitory effects. The overall decoupling state between agricultural CO2 emission and economic development is weak, with different decoupling states observed in different time periods.

Summary: This study analyzes the conditions behind energy-related carbon dioxide (CO2) emissions in Poland after joining the European Union. The research examines various indicators including energy use, CO2 emissions, driving factors, decoupling elasticity status, and decoupling effort status. The findings suggest that energy intensity is the main factor reducing CO2 emissions, while rapid economic growth is the main driver of these emissions. Other factors such as carbon intensity, energy mix, and population also contribute to emissions reduction, albeit to a lesser extent. The study further reveals that Poland experienced strong decoupling between CO2 emissions and economic growth, indicating positive efforts to reduce emissions. However, there is evidence of declining decoupling strength and policy efficiency over time.

Summary: This paper examines the spatio-temporal variations, drivers, and decoupling of CO2 emissions from economic growth in 150 countries from 1990 to 2019. The study reveals an increase in CO2 emissions, driven primarily by economic growth and population growth. It emphasizes the importance of considering income levels and regional disparities in formulating CO2 emission mitigation strategies, and highlights the need for global coordination towards a low-carbon economy.

Summary: This study analyzes the decomposition of agricultural energy and its decoupling with economic output in Pakistan from 1981 to 2020. The results show that agricultural economic output is the major factor influencing energy consumption. Agricultural energy intensity and total agricultural land exhibit increasing returns to scale, while agricultural labor intensity has mixed effects. Strong and expansive negative decoupling is observed, suggesting the potential for further achieving strong decoupling through the use of energy technologies. The findings highlight the importance of adopting diverse energy sources, energy management, increased capital investment, and skilled labor to cope with the increasing energy consumption in the agriculture sector.

Summary: This study uses the Tapio decoupling model to measure the relationship between China's economic development and carbon emissions, and identifies the factors driving carbon emissions with the help of the improved Kaya identity and LMDI decomposition models. The results show that most mining divisions have achieved decoupling and stability, except for the oil and natural gas mining industry. The mining product smelting and processing industry has undergone a major transformation, but there are differences between different sub-sectors.

Summary: The share of emissions from materials has significantly increased and is expected to continue rising in the future. Understanding the environmental impact of materials is crucial, especially from a climate mitigation perspective. This study investigates the role of materials in decoupling CO2 emissions from economic growth and compares it with the role of energy use in the top-19 emitting countries. The results highlight the importance of considering both energy and material-related strategies for achieving decoupling.

Summary: As the largest energy consumer, China has a crucial role in global climate governance by controlling carbon emissions from energy consumption. However, there is a lack of studies exploring emission reduction pathways that align China's economic growth with carbon peaking and carbon neutrality goals from an energy consumption perspective. This paper analyzes the spatial and temporal distribution of carbon emissions in China at the national-provincial level and identifies the driving factors using the LMDI model. The study also examines the decoupling states of China and proposes targeted policy recommendations based on China's energy endowment.

Summary: This study investigates the decoupling state and drivers of the Chinese mining industry and finds an inverted U-shaped relationship between CO2 emissions and economic growth. The economic output effect is the key factor in promoting CO2 emissions and inhibiting decoupling, while the energy intensity effect contributes to suppressing CO2 emissions and promoting decoupling. The energy structure effect shows potential. Factors vary in their role across different subsectors.

Summary: Under the dual pressure of global ecological degradation and economic downturn, emerging industrialized countries need to balance the connection between economy and environment. Using spatial econometric model, the trend and causes of decoupling CO2 and SO2 from economic growth in China were evaluated. The findings show spatial and temporal heterogeneity in the synergistic effect, with higher effect in the western region compared to the eastern region. The results provide valuable insights for policy-makers in emerging industrialized countries.

Summary: The study found that China's CCE increased by 168.37% from 1997 to 2016, peaking at 7948.43 Mton in 2013. The center of gravity shifted from (114.64 E, 34.70 N) to (113.48 E, 35.06 N). By 2016, the economic growth of 18 provinces had achieved a strong decoupling from CCE, while only Xinjiang, Shanxi, and Shaanxi's economic growth increased their dependence on CCE. Activity and energy intensity were the dominant factors driving and curbing the increase of the decoupling indicator.

Summary: Decoupling carbon emissions from economic growth is crucial for the sustainable development of developing countries. This study analyzes the decoupling characteristics of net carbon emissions and the economic growth of marine aquaculture in China, and investigates the contributions of different regions, provinces, and factors using the Tapio decoupling index model and the logarithmic average weight decomposition method (LMDI model). The results indicate that there is a decoupling trend between net carbon emissions and the economic growth of marine aquaculture, but with significant regional differences. The study also identifies the factors that contribute to decoupling, with carbon emission intensity, aquaculture scale, aquaculture efficiency, and aquaculture structure playing varying roles across different regions.
