Summary: The Intergovernmental Panel on Climate Change's mitigation scenarios database is a valuable resource for policymakers, but there are variations in models and scenario designs. This analysis focuses on scenarios with warming limited to 2 degrees C or below, examining the feasibility and trajectory of different fossil fuel reduction pathways. The findings emphasize the importance of clear reduction benchmarks in coal, oil, and gas production and use, along with other climate mitigation targets.

Summary: This paper estimates the impact of COVID-19 on air travel demand and emissions in Brazil. The results show a significant decrease in both demand and emissions, but fuel efficiency decreased and passenger demand had recovered to pre-pandemic levels by the end of 2020. This indicates the challenges of reducing emissions in the aviation sector in the short term.

Summary: Despite the significant contribution of the aviation sector to the global economy, it also has adverse impacts on climate change. While improvements have been made in technology, sustainable aviation fuel, and design, greenhouse gas emissions in the aviation sector continue to rise steadily. Global efforts, including continued research and development, enforcement of market-based mechanisms, and techniques to reduce emissions, are crucial to mitigate these adverse effects and achieve emissions reduction goals in the future.

Summary: Understanding the relationship between carbon emissions and air transportation development is crucial for achieving green development in China's civil aviation industry. The study reveals that there is room for efficiency improvement in the overall transportation process, and carbon emissions are mainly affected by fossil fuel consumption. The decline in potential energy intensity plays a significant role in decoupling progress, while the external economic environment and potential transportation intensity are key inhibitors to decoupling development.

Summary: This study focuses on the role of eco-patents and trademarks in reducing carbon dioxide emissions, finding that they have a positive impact on mitigation efforts, but energy consumption, urbanization, and economic growth are the main polluters. Environmental policies and taxes have different impacts on emission reduction efforts in different regions, and there are causal relationships among variables in different countries.

Summary: The study highlights the importance of addressing the risks of mitigation deterrence and increasing mitigation efforts in the short term due to uncertainties in future CDR deployment. Additionally, there is a need for additional emissions reductions if there is a risk of specific CDR deployment failures in the future.

Summary: The study examines the impact of China's green policy on climate change mitigation. It suggests that China can significantly reduce CO2 emissions in the early stages of greening, but the effect diminishes as the process advances. Additionally, there is spatial variation in the impact of greening on CO2 emissions reduction in China.

Summary: The low-carbon development of the air transport industry is crucial for China in achieving its carbon peak and carbon neutrality targets. This study collected flight data in China from 2017 to 2020 and established databases to improve the understanding of aviation CO2 emissions. The results showed the impact of the COVID-19 pandemic on aviation CO2 emissions and highlighted the need for sustainable development in the industry.

Summary: Excessive reactive nitrogen (Nr) contributes significantly to PM2.5 air pollution in Europe, posing health challenges. This study identifies optimal Nr control strategies for Europe, considering emission estimations, air quality modeling, exposure-mortality modeling, Nr control experiments, and cost data. The results show that reducing Nr emissions would greatly reduce PM2.5 and premature deaths in Europe, with NH3 control being more cost-effective than NOx control.

Summary: As climate change due to CO2 emissions is a crucial concern, the role of households in reducing emissions through behavioral intervention is significant. This study expands traditional EKC theory by including household-level social capital and income, and examining disaggregated CO2 emissions. The results indicate that higher community attachment and social trust are associated with greater concern for global warming. Low-income countries exhibit higher levels of concern about global warming compared to high-income countries. Individual differences between low and high levels of community attachment and social trust are more pronounced in high-income countries. The separate effect of income leads to increased CO2 emissions, while social capital is associated with decreased emissions. The combined effect of income and social capital reduces the positive impact of income on CO2 emissions. By incorporating social capital with household income, the turning points of household income for emissions reduction can be lowered. Overall, the findings suggest that increasing social capital may be an effective approach for reducing emissions at the household level.

Summary: Net-zero greenhouse gas (GHG) emissions targets are driving interest in biomass-based negative emissions and bioenergy from marine sources. This study assesses the costs and climate benefits of global seaweed production using growth and technoeconomic models. The results indicate that seaweed-based climate benefits are feasible, but further research is needed to reduce economic and biophysical uncertainties.

Summary: The COVID-19 pandemic had a significant impact on the aviation industry in 2020, leading to uncertainty about its future. This paper explores different recovery scenarios and ongoing demands, focusing on aviation emissions-related policies like CORSIA and the EU ETS. By using the Aviation Integrated Model (AIM2015), the study projects potential changes in long-term demand, fleet, and emissions. Depending on the recovery scenario, cumulative aviation fuel use by 2050 may be up to 9% lower compared to scenarios that do not consider the pandemic. The findings suggest that global aviation CO2 emissions are likely to exceed industry goals, even when accounting for the pandemic's demand effects, unless new policies and technological advancements are implemented.
