Summary: This paper discusses a Green Vehicle Routing Problem that considers both electric and conventional trucks. A bi-objective programming model is developed to minimize transportation costs and Greenhouse Gas (GHG) emissions. The study finds that increasing charging power and the number of charging stations can decrease transportation costs, and a slight increase in transportation costs can lead to a significant reduction in GHG emissions.

Summary: The study found that pillow pouches have the lowest environmental impact among milk packaging options in Canada, regardless of location. This is mainly due to their lower mass per functional unit compared to jugs and cartons. Even if disposed in a landfill or incinerated, pillow pouches perform better across all impact categories compared to alternatives.

Summary: China's promotion of vehicle electrification has led to an increase in mercury emissions. With current technologies, the life-cycle mercury emissions of battery electric vehicles are 92% higher than conventional gasoline vehicles, primarily due to high mercury emissions from coal-based electricity generation. Measures such as decarbonizing the electric grid and implementing mercury-specific emission control can help mitigate this unintended increase in mercury emissions caused by vehicle electrification.

Summary: Vehicle electrification is seen as a way to achieve zero emissions, but the current timeline for phasing out internal combustion engines may not be enough to meet climate goals, particularly in regions where two-wheelers dominate. A new modeling framework was developed to analyze fleet turnover and greenhouse gas emissions in Taiwan, which has the highest scooter density globally. The transition to electric vehicles in Taiwan's net-zero pathway by 2050 will bring climate benefits, but may still fall short of the target. However, increased adoption of EVs will eventually be offset by clean grid development in the power sector.

Summary: Designing efficient policies, such as fuel economy standards and incentives for electric vehicles, is crucial to reduce transport GHG emissions and tackle climate change. However, solely relying on tailpipe-based standards will not be enough to meet sectoral emission goals. Switching to well-to-wheels based standards and implementing complementary policies to regulate embedded emissions and low carbon fuel production can effectively close the mitigation gap and achieve holistic emissions reduction. Incorporating life cycle assessment approaches into the regulatory framework is necessary to provide sufficient GHG emissions reduction and contribute to overall carbon reduction commitments.

Summary: Tropical peatland is a significant carbon store, but drainage of Asian peat soil has increased in the past 20 years to meet the demand for agricultural land. This study evaluates the life cycle of palm oil production in Hanau and Sungai Rungau facilities in Indonesia and quantifies the reduction in greenhouse gas emissions and nature occupation achieved through measures such as reducing cultivated peat soil area and drainage depth. The results show that both facilities have lower emissions and less impact on nature occupation compared to non-certified palm oil.

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.

Summary: Demand-side management is crucial to smart energy systems. This paper proposes a data-driven approach to understand the relationship between energy consumption patterns and household characteristics for better DSM services. The proposed method uses a clustering algorithm to generate optimal customer groups for DSM and a deep learning model for training. The model can predict the possibility of DSM membership for a given household. The results demonstrate the usefulness of weekly energy consumption data and household socio-demographic information for distinguishing consumer groups and the potential for targeted DSM strategies.
