Summary: Increased forest fires in the future present opportunities for salvage logging and replanting, which can reduce greenhouse gas emissions compared to doing nothing and relying on natural regeneration. Salvage logging can produce useful products for society, while replanting can establish seedlings with genetic gain and increased climate resilience. However, the net greenhouse gas reduction benefits are not realized for several decades due to emissions from harvesting wood products. Mitigation efforts should focus on reducing wildfire risks and emissions in the first place, rather than rehabilitating post-fire outcomes.

Summary: Hydropower, as the largest renewable electricity source, has the potential to contribute to a low carbon future. However, research indicates that hydropower reservoirs are a significant source of biogenic greenhouse gases. Evaluating global emissions from reservoirs, it is found that they account for 1.0% of global anthropogenic emissions. Although the carbon intensity of hydropower is lower than that of fossil fuels, it is higher than other renewable energy sources, primarily due to shallow and eutrophic reservoirs. Additionally, the carbon intensity of reservoirs is expected to increase with the construction and planning of new dams.

Summary: This study examines the impact of natural resources, carbon emissions, and renewable electricity on the economic growth of low-income economies from 1984 to 2021. The empirical findings show that oil rents have a negative effect on economic growth, while natural gas has a positive impact on low-income economies. Additionally, carbon emissions increased due to the resource curse and inefficient extraction of natural resources. Renewable electricity is found to hinder economic growth by hindering the transition to renewable energy. The study also identifies a bi-directional causal association with the economic performance of low-income economies. Based on these findings, the paper offers policy implications for policymakers in low-income economies.

Summary: In the past thirty years, there has been a significant growth in the use of natural gas as an energy source for Mexican electricity production, with its share increasing from 7% in 1990 to 62.3% in 2020. However, this co-dependence between electricity and natural gas systems raises concerns about the decarbonization objective of the electricity sector. Through a decomposition analysis of electricity greenhouse gas (GHG) emissions in Mexico from 1990 to 2015, it is found that the activity effect has been the main driver of GHG emissions growth, while the structure and energy intensity effects have contributed to limiting that growth. The small contribution of the carbon coefficient effect in mitigating GHG emissions raises concerns about the role of natural gas, as it could hinder the development of renewable energy and lead to carbon lock-in and stranded assets in the long run. Given these concerns, it is concluded that an energy policy aiming towards a low-carbon energy system should consider a composition of natural gas + renewable energies + energy efficiency.

Summary: This article reviews various studies on the greenhouse gas (GHG) emissions of the information and communication technology (ICT) sector and its potential for reducing GHG emissions in other sectors. The results show that the ICT sector contributes between 1.5% and 4% of global GHG emissions, with a significant portion attributed to the production of ICT end-user devices. However, the estimation of GHG impacts from device production remains uncertain. The studies on the potential of ICT to reduce GHG emissions are also less robust, primarily due to uncertainty regarding real-life use case impacts and economy-wide rebound effects.

Summary: The injection of supercritical CO2 (SCCO2) has a significant impact on the petrophysical properties and pore structure of shales during geological storage. The alteration of mineralogy and pore structure is influenced by SCCO2 treatment, with clay-rich shales showing greater changes in pore volume compared to quartz-rich shales. The development of micro-cracks in the surface of Mancos shale creates new pores and increases pore volume. The results provide important insights into the effect of CO2 on the pore structure and mineralogical alteration of shale.

Summary: This study examines the technical and economic feasibility of carbon utilization and storage in abandoned and nearly depleted gas fields through CO2-enhanced gas recovery and storage experiments. The results indicate that while the gas reservoir is heterogeneous, a certain recovery rate can be achieved with appropriate injection and production rates. However, the economic model shows that the cost of carbon capture, transport, and storage exceeds the revenue from natural gas utilization, highlighting the need for further optimization of the economic model to reduce uncertainties.

Summary: Subsurface hydrogen storage is crucial for large-scale energy supply and combating climate change. To ensure storage safety, comprehensive risk management protocols are needed due to hydrogen's flammability and diffusivity. This study investigates the role of hydrogen diffusion process in shale reservoirs and suggests that depleted shale reservoirs may offer advantageous storage characteristics. Molecular dynamics simulations reveal that diffusivity decreases with increasing pressure, and the impact of slit pore size and kerogen type on diffusion is minimal.

Summary: Unconventional shale resources play a crucial role in addressing energy challenges. However, the water stress caused by shale development at a national scale is not well understood. A new model based on the life cycle is proposed to estimate water intensities of individual shale wells, and China and the US are used as case studies. It is found that China has lower water stress overall, but the province of Xinjiang faces the highest water stress, requiring long-distance water diversion or deep aquifer extraction. In the US, Louisiana, Texas, Arkansas, Colorado, and Pennsylvania have the highest water stress due to limited water availability.
