Summary: China's clean air actions from 2013-2020 have led to a net reduction of 2.43 Gt CO2 emissions by promoting the transformation of the country's energy system. The co-benefits of these measures far outweigh the additional CO2 emissions, signaling the significant climate benefits of tackling air pollution.

Summary: This study provides empirical evidence of the co-benefits of a CO2 emissions trading system in Shanghai, China, showing a significant negative association between CO2 prices and SO2 emissions. The co-benefits are limited to specific sectors and are stronger during months when firms need to balance their annual CO2 emissions.

Summary: Based on China's pilots of SO2 ETS and CO2 ETS, this study finds that these policies have effectively reduced SO2 and CO2 emissions, and the CO2 ETS has achieved co-benefits by reducing SO2 emissions. However, the effectiveness of SO2 ETS in reducing CO2 emissions is limited due to the maturity of SO2 capture technologies.

Summary: Recent studies have shown that tropical hydroelectric reservoirs can emit substantial greenhouse gases to the atmosphere, with downstream emissions varying greatly over different timescales due to reservoir stratification and dam operation. Failing to account for seasonal or subdaily variations in downstream carbon emissions could lead to errors of up to 90% when estimating the reservoir's annual emissions.

Summary: Reservoirs are crucial for human societies, but their carbon emissions have a significant impact on global climate change. This study reveals that global reservoir carbon emissions peaked in 1987 and have been gradually declining since, mainly due to decreasing carbon dioxide emissions as reservoirs age. However, reservoir-induced radiative forcing continues to rise due to ongoing increases in reservoir methane emissions.

Summary: Studies on biogas production from different organic materials in anaerobic conditions are conducted worldwide, with key parameters including raw material potential, production processes, economic analysis, and environmental impacts. Chicken manure is a significant raw material in biogas production, with research showing the potential for producing 8.58 million m(3) of biogas annually from processing about 110,000 tons of waste. This process also generates 17 GWh/year of electricity, 16 GWh/year of thermal energy, and reduces CO2 emissions by 13.86 thousand tons/year.

Summary: Replacing coal energy with biomass energy in power plants is an important measure to reduce air pollutants and CO2 emissions in China. The estimated available biomass (OAB) and potentially available biomass (PAB) of power plants in 2018 are 423-1013 Mt, with higher values in provinces with higher population and crop yields. When all the PAB were consumed, the emissions of NOx, SO2, PM10, PM2.5, and CO2 would decrease significantly. However, the PAB will not be sufficient to meet the biomass power growth estimated for future years, but advanced technologies like BECCS can further reduce CO2 emissions.

Summary: Inefficiencies in the transmission and distribution of electricity can result in compensatory electricity generation and air pollution. This study estimates the air pollutants associated with aggregate and non-technical losses at national and subnational scales using life cycle assessments and uncertainty analyses. The global analysis indicates significant emissions, such as 1 Gigatonne of CO2eq. Investments in T&D infrastructure can enhance the cost-effectiveness of renewable energy in a decarbonized system.

Summary: This study evaluates the effects of global warming scenarios of 1.5 degrees C and 2 degrees C on the co-benefits between hydropower and irrigation in the Mekong River basin using an integrative analysis. The results show a decline in hydropower generation and irrigation water supply under both warming scenarios, with the co-benefits being more undermined by the higher temperature increase. The consideration of protected areas in the basin could enhance the co-benefits under 2 degrees C global warming compared to 1.5 degrees C global warming.

Summary: China aims to achieve carbon neutrality by 2060 and is actively developing renewable energy, particularly hydropower. However, the ecological impacts associated with hydropower plants (HPs) hinder their sustainable development. This study evaluates the environmental impacts and ecosystem service losses (ESLs) of 43 HPs in China using a framework that combines life cycle analysis and ecosystem service assessment. The results show that the preparation and construction stages of HPs contribute the most to environmental impacts, while ESLs mainly result from biodiversity and water supply losses. The pricing mechanisms of HPs also fail to adequately account for the associated ecological costs, highlighting the need for revision.

Summary: The electricity sector in China is the biggest contributor to CO2 emissions and water consumption in industrial sectors. The transition to low-carbon in China's electricity sector has led to a reduction in cooling water usage. Using a Quasi-Input-Output model, this study quantifies CO2 emissions and virtual water embodied in electricity trade. Results show that the low-carbon transition has contributed to water-saving in China's electricity sector.

Summary: National-level climate actions are crucial for achieving global temperature goals, with 2050 emissions being a key focus. The lack of coordination and compatibility in national scenarios hinders assessments of individual nations' climate policies. A systematic and standardized scenario framework can help guide individual national scenario creation, paving the way for comprehensive assessments in the future.

Summary: Thailand's NDC aims to reduce 20 to 25% of greenhouse gas emissions by 2030. However, achieving more stringent reduction targets requires significant transformations in Thailand's fossil fuel-dependent energy system. A computable general equilibrium analysis reveals that renewable energy and carbon capture and storage technologies will play a major role in the power generation mix by 2050 if 100% GHG emission reduction is to be achieved.

Summary: This paper examines the economic impacts of achieving net-zero greenhouse gas emissions in Thailand by 2050. Using a dynamic Asia-Pacific Integrated Model/Computable General Equilibrium (AIM/CGE) model, the study analyzes the macroeconomic effects of Thailand's emission targets. The results suggest that Thailand needs to increase its efforts in GHG mitigation actions to reach peak emissions by 2025 and net-zero emissions by 2050. Improving energy efficiency, expanding renewable energy utilization, and implementing behavioral changes are identified as key strategies for decarbonization.

Summary: There is a growing demand for net-zero emissions of CO2 to support the Paris Climate Agreement goals, but developing countries face challenges due to their desire for economic growth and climate resilience. Understanding the economic and technical characteristics of net-zero emissions concepts is crucial, and identifying co-benefits can help overcome constraints. A study of Nepal's net-zero emissions strategy revealed significant reductions in air pollutants and improvements in energy security and equity. These findings provide valuable input for policymakers and stakeholders.

Summary: This study presents a methodology and dataset for examining compound wind and solar energy droughts, as well as the first standardized benchmark of energy droughts across the Continental United States (CONUS) for a 2020 infrastructure. The results show that compound wind and solar droughts have distinct spatial and temporal patterns across the CONUS, and the characteristics of energy droughts are regional. The study also finds that compound high load events occur more often during compound wind and solar droughts than expected.

Summary: This paper provides insights into the optimal configuration of CSP plants with different penetrations of wind power by proposing an unconstrained optimization model. The results suggest that large solar multiples and TES are preferred in order to maximize profit, especially when combined with high penetrations of wind and photovoltaic plants. Additionally, the study demonstrates the economy and feasibility of installing electric heaters (EH) in CSP plants, which show a linear correlation with the penetration of variable energy resources.
