Summary: The development of plug-in electric vehicle market is influenced by international regulations, including super-credits and leakage effects. Due to these effects, sales of plug-in electric vehicles in China, the U.S., and the EU will result in greenhouse gas emissions increases of over 1 billion tonnes of CO2 equivalent. Future regulatory designs should incentivize the development of new technologies while also reducing the risk of emissions increases elsewhere.

Summary: Vehicle ownership restrictions have the potential to effectively address automobile-related externalities such as congestion, pollution, and greenhouse gas emissions. This study uses synthetic control, regression discontinuity, and dynamic panel analysis to estimate the impacts of these restrictions on new car sales, fuel consumption, and tailpipe emissions in Chinese cities. The findings suggest that without restrictions, new car sales would have been significantly higher, and so would have been gasoline consumption and tailpipe emissions. The implied price per unit of externality produced by these restrictions is relatively high, comparable to the price of gasoline in China. These results have important implications for policymakers worldwide in their efforts to reduce automobile-related externalities.

Summary: This paper evaluates the greenhouse gas emissions of shared electric bicycles (SEB) using life cycle assessment and finds that the emissions in the production and operation stages are 379.6173 kg CO2-eq and 183.4663 kg CO2-eq, respectively. However, the use stage results in a reduction of 1049.8374 kg CO2-eq, resulting in a net GHG reduction of 487.3923 kg CO2-eq throughout the SEB's life cycle. Additionally, non-recyclable parts of the SEB take 48 years to degrade in landfills.

Summary: This study conducted a life cycle assessment of five typical vehicle models in Suzhou City and analyzed their energy consumption, greenhouse gas emissions, and air pollutant emissions. The results showed that battery electric vehicles (BEVs) have advantages over other vehicle types in replacing internal combustion engine vehicles (ICEVs) in China's road electrification policy. Under the aggressive Sustainable Development Scenario, the greenhouse gas emissions of light-duty vehicles (LDVs) would peak before 2026, ahead of China's target by 2030, with an -100% share of electric vehicles (EVs) in 2040 resulting in lower emissions.

Summary: The State Council of China released an auto industry development plan in 2012 to accelerate the deployment of energy-saving and new energy vehicles, with set fuel economy targets for 2020, 2025, and 2030. A study on auto companies' responses to these targets revealed that, given the current rate of technical progress and efficiency increase, Chinese light-duty car manufacturers still need to accelerate the development and adoption of fuel economy technologies to reach the mandatory fleet-average fuel economy targets on time.

Summary: Analysts need to consider the shift in vehicle sales from cars to light trucks to accurately project fuel consumption, greenhouse gas emissions, and consumer spending. Changing assumptions regarding the sales mix can lead to a 10% variation in energy consumed by light-duty vehicles on the road in the United States. Sales scenarios with a higher proportion of light trucks and fewer cars result in higher petroleum consumption (3-8% higher than EIA forecasts), greenhouse gas emissions (5-7% higher), and consumer spending on vehicles and fuel (4-9% increase). This additional energy consumption can be offset by implementing additional technologies for these vehicles. If sedans are phased out in favor of larger SUVs, a sales share of 30% battery electric vehicles or 39% hybrid electric vehicles would equal the emissions of the EIA Reference Case.

Summary: The study found significant variations in well-to-wheels greenhouse gas emission intensities of plug-in electric vehicles (PEVs) compared to gasoline vehicles at the provincial level in China in 2017. In some northern provinces, due to coal-based electricity and cold weather, the emission intensities of BEVs and PHEVs were higher than gasoline vehicles. It is suggested that province-specific policies should be implemented for reducing greenhouse gas emissions in on-road transportation in China.

Summary: The study found that individual travel and dwelling patterns have significant impacts on the spatial and temporal opportunities for electric vehicle charging and the installation of charging infrastructure. Providing more non-home charging opportunities based on travel and dwelling patterns can reduce system costs and emissions. The study also observed charging at non-home locations mainly during daytime and a secondary peak in charging at home locations during nighttime.

Summary: The paper proposes a novel deep learning-based prediction framework, aTCN-LSTM, for accurate cooling load predictions. The framework utilizes a gate-controlled multi-head temporal convolutional network and a sparse probabilistic self-attention mechanism with a bidirectional long short-term memory network to capture both temporal and long-term dependencies in the cooling load sequences. Experimental results demonstrate the effectiveness and superiority of the proposed method, which can serve as an effective guide for HVAC chiller scheduling and demand management initiatives.

The study finds that social interaction increases the likelihood of farmers adopting SWC, and internet use moderates this effect. The positive impact of social interaction on SWC adoption is more pronounced for farmers in larger villages and those who join cooperative societies.
