Summary: In a biomass-to-LPG intervention trial in Peru, it was found that kitchen area NO2 concentrations were significantly lower in the LPG intervention group compared to the biomass control group, although some samples still exceeded WHO standards. Most participants in the LPG intervention group had 48-hour personal NO2 exposure levels below WHO guidelines, but further research is needed to understand the potential health risks of LPG-related NO2 emissions.

Summary: The promotion of clean cooking fuel and technologies contributes to achieving sustainable development goals and empowering women. This study focuses on the impact of clean cooking fuels and technologies on greenhouse gas emissions in BRICS nations. The results show that energy use, trade openness, and urbanization promote greenhouse gas emissions, while the use of clean cooking and foreign capital can help reduce environmental degradation and achieve environmental sustainability. Therefore, it is important to develop clean energy at the macro level and promote the use of clean cooking fuel and technologies at the household level.

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: In the past two decades, the use of biomass as a carbon-neutral energy source has nearly doubled. The main challenge of biomass heaters is their impact on the environment and human health through particulate matter and gaseous emissions. This study critically analyzes the emissions and thermal efficiency of solid biomass heaters, considering different parameters such as combustion conditions, fuels and stove types, and biomass characteristics. The research shows that factors such as biomass type and size, user behavior, tar fouling, inlet air characteristics, and appliance structure significantly affect the efficiency of biomass-fired heaters. New techniques have been developed to improve emissions and efficiency, such as using different wood types and sizes, utilizing automatic pellet heaters, or adding additive materials.
