Summary: The UK government's policy of support for shale gas extraction was terminated in November 2019 due to seismicity concerns, and a moratorium was placed on fracking in England. The scope and definition of unconventional extraction methods remain ambiguous, prompting a call for a ban on such methods until further clarification can be made. The focus should shift towards engineering practices for target rocks rather than fluid volume injection to address climate change concerns.

Summary: We present a novel experimental and modeling approach for lab-scale multistage hydraulic fracturing in PMMA and study pressure-based methods for monitoring the process. Our results show injection-induced rotational deformation and asymmetric growth of the hydraulic fracture. We also identify the role of undrained deformation in generating pressure responses at the monitoring well. This study demonstrates the usefulness of lab-scale hydraulic fracturing in estimating the geometry and properties of hydraulic fractures using pressure data from offset wells.

Summary: Air pollution caused by asphalt-covered surfaces contributes to chronic illnesses and approximately 4.5 million deaths annually. The majority of the global population is expected to reside in urban areas by 2050, emphasizing the importance of air quality and its impact on health in these locations. This study investigates the emissions of nitrogen oxides (NOx) from fresh and aged asphalt mixtures under simulated atmospheric conditions in the laboratory. The results demonstrate that asphalt aging affects NOx emissions, and exposure to car exhaust can regenerate these emissions. A numerical model applied to Athens, Greece reveals that this previously unknown source accounts for up to 20% of NOx emissions in certain areas. It is crucial to include asphalt-covered surfaces in emission inventories and incorporate them into models for a comprehensive understanding of factors influencing urban air quality.

Summary: Emission inventories are essential for modeling studies and pollution control. However, traditional emission inventories are usually outdated and cannot accurately reflect actual emission changes. In this study, a four-dimensional variational assimilation system was used to optimize sulfur dioxide emissions during the early period of the COVID-19 pandemic in China. The results showed that the optimized emissions better reflected the impact of lockdown measures on emissions.

Summary: The rising atmospheric methane burden and the uncertainty surrounding its causes are the focus of this study. The researchers present a collection of new delta C-13(CH4) signatures for tropical wetlands and rice fields, which provide insights into isotopic variation and potential seasonal shifts. Long-term monitoring at two observatories in Bolivia and Botswana shows that biogenic methane sources, particularly wetlands, dominate the records. The findings suggest significant seasonal variation in tropical wetland delta C-13(CH4) signatures, highlighting the need to incorporate this variability into future global and regional models.

Summary: Hydraulic fracturing, or fracking, is a short phase in unconventional oil and gas development with a significant pre-operational period that often goes unnoticed in air quality evaluations. This study quantifies the change in air pollution during the pre-operational phase at a shale gas exploration site in England. The results show that the preparative work for fracking significantly increases NOx emissions and reduces O3 levels compared to the business as usual scenario. This finding highlights the potential adverse effects of fracking on air quality and should be taken into consideration.

Summary: This article reports on high-frequency measurements of nitrous oxide (N2O) in the city of Bristol, UK, from November 3, 2019, to November 26, 2021. The data show elevated N2O concentrations during late evening and early morning hours on weekends, with no significant correlations with other measured species, suggesting the use of N2O as a recreational drug. The estimated emissions from recreational N2O use in the UK were 12-14 tonnes between 2012 and 2020, while a much larger estimate of 89-954 tonnes was derived for the year 2020 with revised estimates of canister size, N2O mass, and frequency of drug use.

Summary: This article reviews the potential air quality impacts of using hydrogen-diesel blends in heavy-duty diesel engines. Engine load is identified as a key factor influencing NOx emissions, and the variation in experimental parameters complicates the relationship. Exhaust gas recirculation and existing aftertreatment technologies may help reduce NOx emissions. However, there is a disconnect between commercial reporting and peer-reviewed literature regarding the impact of hydrogen fuel on NOx emissions.
