Summary: This article studies the participation of variable resources in centralized regulation markets, analyzing the impact of regulation offers on quantity and price as well as the calculation of opportunity costs in case of imperfect regulation delivery. The operator-determined performance targets and settlement adjustments affect the regulation provision of variable resources.

Summary: With the increasing use of renewable energy in electricity generation, there will be a higher variability in residual demand, posing challenges to the stability and flexibility of power systems. Demand response, achieved through dynamic tariffs, is a possible solution where consumers are incentivized to shift or reduce peak load. By modeling the retail market using a two-stage dynamic game, we find that dynamic tariffs increase the retailer's profit and can benefit consumers and retailers under market regulations. Additionally, the interaction between demand-side management stimuli and market regulation can further decrease consumer-level electricity demand, increase retail profit, and lower consumers' electricity bills.

Summary: The electricity industry is undergoing technological changes driven by sustainability concerns. The focus of market design has shifted towards addressing environmental externalities. To address this challenge, we propose an incentive-based market clearing mechanism using a power network representation with incomplete information on generation costs, overcoming the limitations of price caps in mitigating market power.

Summary: The study revealed that the efficiency of thermal power generation in China is relatively low with a fluctuating growth trend. Cost-based environmental regulation has a significant single-threshold effect on thermal power generation environmental governance efficiency, showing a significant positive effect when the proportion of regulation to GDP is below a certain threshold, but diminishing as the proportion increases.

Summary: This research evaluates the applicability of the VCG mechanism against a profit-maximizing producer with market power, taking into account the distortion in the reported technical parameters. A regulatory method based on estimating the producer's truthful bid is proposed to ensure optimality of dispatch and protect market prices from the producer's market power.

Summary: This paper discusses the impact of environmental regulation on product quality for different types of firms. The findings show that environmental regulation can help improve product quality, but heavy-pollution firms may experience a decrease in quality due to greenwashing. On the other hand, low-pollution firms are more incentivized to improve product quality through environmental regulation. Financial constraints and state ownership also play a role in influencing product quality.

Summary: This paper investigates the potential contribution of interconnectors to support the security of interconnected power systems. The proposed modeling setup introduces a new paradigm shift and evaluates the impact on market indicators. By modeling interconnectors in the market, the potential inefficiency of market solutions is quantified, and the value of interconnectors on system efficiency and security is assessed through a case study.

Summary: This study investigates the relationships between different types of environmental regulations and firm performance. The results show that mandatory environmental regulation has negative effects on firm performance, while voluntary environmental regulation contributes positively to performance. Investors tend to overreact to environmental regulation, overestimating the benefits of voluntary regulation and the negative effects of mandatory regulation. Firm bargaining power can mitigate the negative effects of mandatory regulation on performance.

Summary: This study investigates how customers' environmental regulation impacts suppliers' green innovation. Using a unique dataset of customer-supplier relationships among listed firms in China, the findings show that suppliers increase their green innovation in response to intensified environmental regulation pressure from customers. This effect remains consistent across different measures of green innovation and environmental regulation, as well as a different sample. The study also finds that the influence of customers' environmental regulation on suppliers' green innovation is positively associated with the customers' bargaining power. Overall, these results contribute to the growing body of research on the significant role of the supply chain in firms' decision making processes.

Summary: This study used satellite imagery and a methane emission model to estimate the surface water extent and diffusive methane fluxes in wetlands, showing that wetlands smaller than 1 hectare were responsible for the majority of emissions. Considering the dynamic inundation of forested wetlands resulted in 49%-62% lower emission totals compared to models using a single estimate for each wetland's size.

Summary: Methane emissions from small freshwater ecosystems are a major uncertainty in the global methane budget. The study found that inundation extent and duration, as well as the direction of water level change, are major drivers of methane emissions in seasonally inundated forested wetlands. Modeling the hydrologic regime of these wetlands can lead to more accurate estimation of methane emissions.

Summary: Brazilian beef production is shifting from extensive to intensive pasture systems, leading to increased CO2 and N2O emissions. The study highlights the importance of conservation practices to prevent hot moments of N2O emission arising from pasture intensification in Brazil, with different emission rates and dynamics observed based on weather conditions and soil management practices.

Summary: This study analyzed the effects of sugarcane cultivation on methane fluxes and concentrations in tropical streams in Southeastern Brazil, finding higher methane fluxes and concentrations during the summer and in streams with preserved catchments. Water chemistry factors such as dissolved oxygen, dissolved organic carbon, water velocity, and conductivity were found to influence methane concentrations in the studied streams.

Summary: The decline in phosphorus and the increase in nitrogen to phosphorus ratios have resulted in re-oligotrophication in rivers and estuaries of high-income countries, while widespread eutrophication occurs in low-income countries. The biotic response and ecological effects of these changes, as well as the N:P imbalance, need further investigation. The regime shift from phytoplankton to macrophyte dominance, documented in shallow lakes, is less observed in rivers and estuaries.

Summary: Wetland soils serve as a vital carbon sink globally and play a crucial role in carbon management and accounting. However, the lack of reference information and incomplete understanding of wetland variability hinder the accurate assessment of carbon storage potential. This study aimed to quantify the variability in wetland soil organic carbon (SOC) stocks on a depressional landscape and investigate the role of hydrology and relative topography. The results indicate high variability within and among wetlands with similar characteristics, suggesting the need to explicitly address uncertainties when inferring ecosystem processes. Hydrology and relative topography were found to be important factors in explaining SOC stock variability, emphasizing the importance of considering these factors in large-scale analyses and wetland restoration efforts.

Summary: Although native vegetation plays a crucial role in maintaining aquatic ecosystems, forest restoration efforts have been found to decrease water yields worldwide. This study clarifies the connection between forest restoration and water services and identifies gaps in the literature that hinder the assessment of the benefits of forest restoration on water yields. The authors suggest strategies to improve forest restoration planning and implementation and emphasize the need for future research to consider hydrologic parameters beyond annual streamflow and encompass broader spatial-temporal scales.
