Summary: Household energy consumption in Qinghai Province, China results in uneven distribution of greenhouse gas and air pollutant emissions, with the highest emissions in pastoral zones and CO2 being the primary greenhouse gas. Dung burning is the main cause of high PM2.5 emissions in pastoral areas, while coal use is the primary cause of emissions in agropastoral and agricultural zones. Integration of household energy policies with rural development is necessary for a transition towards cleaner fuels.

Summary: Cyclophyllidea is the most species-rich order of tapeworms, with significant health impact on wildlife, livestock, and humans. Through collection and sequencing of specimens from rodents in Qinghai-Tibet Plateau, several putative new species were identified. Additionally, three known species were found, suggesting their wide distribution in western China. The divergence time estimates indicate a strong association between species differentiation and biogeographic changes resulting from the uplift of the QTP, supporting the hypothesis of host-parasite co-evolution.

Summary: This study conducted a wintertime field campaign in northern China to assess indoor PM2.5 variations. It was found that indoor PM2.5 concentration was about 60% lower in households using clean heating approaches compared to those burning traditional fuels. The results also showed that a transition to clean coals or biomass pellets could reduce indoor PM2.5 by 20%, and further switching to clean modern energies would reduce it an additional 30%, highlighting the significant benefits of promoting clean transitions in household heating activities.

Summary: In order to achieve carbon neutrality by 2060, China needs to make significant changes to its socioeconomic systems and allocate emissions responsibility appropriately. Traditional methods of responsibility delineation can lead to double counting, so an alternative method based on economic welfare gains from environmental externalities has been refined. This approach ensures that the responsibilities of consumers and producers add up to the total emissions. Applying this method to 48 countries and 31 Chinese provinces reveals variations in responsibilities, indicating potential for more comprehensive and accessible policy goals.

Summary: International trade redistributes production activities, affecting CO2 emissions by moving them to places with different emission intensities. This study focuses on the convergence of emission intensities between exporters and importers, finding that the relocation of production activities from developed to developing countries increased global emissions in the early 2000s. However, the narrowing emission intensities and changing trade patterns have led to declining net emissions in trade in the past decade.

Summary: China, as the world's largest industrial producer, faces significant industrial atmospheric pollution, especially from particulate matter, SO2, and NOx emissions. In order to better understand industrial emission characteristics, a nationwide and up-to-date air pollutant emission inventory named Chinese Industrial Emissions Database (CIED) has been created, utilizing real smokestack concentrations from China's continuous emission monitoring systems (CEMS) during 2015-2018. The use of this CEMS data allows for direct estimation of industrial emission factors and absolute emissions, increasing estimation accuracy and reliability.

Summary: The climate econometric analysis is increasingly used to evaluate climate risks and understand economic impacts caused by climate change. This article reviews the literature on growth and level effects, temperature variables' forms and functional forms, and the model specification. An approach for combining empirical findings with climate change integrated assessment models (IAMs) to improve damage modeling is also introduced. The findings show that damage estimates through growth effects are generally larger than those through level effects. Changing the time resolution of temperature variables, introducing non-linearity into econometrics functions, and specifying temperature deviation can reveal diverse impact mechanisms and adaptation effects. Combining cross-sectional and panel models enables the examination of economic impacts at different future times.

Summary: The outbreak of COVID-19 has had profound impacts on carbon emissions in China, particularly through structural changes in the determinants of carbon emissions. The study reveals that per capita final demand has contributed to slower emissions growth, while production structure has driven a greater increase in carbon emissions. Export-led emissions growth has rebounded, and investment-led emissions have become more concentrated in the construction sector. The carbon intensity of several heavy industries has increased, indicating a deterioration in production structure. Policymakers should focus on increasing investment in low-carbon industries and shifting towards consumption-led growth for a green recovery from the pandemic.

Summary: This paper proposes a grey box model for fuel consumption prediction of wing-diesel hybrid vessels based on feature construction. By using both parallel and series grey box modeling methods and six machine learning algorithms, twelve combinations of prediction models are established. A feature construction method based on the aerodynamic performance of the wing and the energy relationship of the hybrid system is introduced. The best combination is obtained by considering the root mean square error, and it shows improved accuracy compared to the white box model. The proposed grey box model can accurately predict the daily fuel consumption of wing-diesel hybrid vessels, contributing to operational optimization and the greenization and decarbonization of the shipping industry.
