Summary: In this paper, a multiregional dynamic computable general equilibrium model is developed to examine the impact of China's carbon peaking and energy transition goals on regional economic development in 2030. The results show that the carbon pricing policy has negative effects on the economy and exacerbates regional economic imbalance, but it promotes total energy control. Targeted power investment policy promotes economic development, alleviates regional economic imbalance, and incentivizes nonfossil energy technologies. It may be feasible to achieve the carbon peaking and carbon intensity goals in 2030, but the total energy control and clean energy development goals present challenges. Targeted power investment combined with flexible carbon pricing helps reconcile multiple policy goals and regional economic development balance.

Summary: This study uses the Low Emissions Analysis Platform (LEAP) software to model future power generation scenarios using renewable energy sources in order to assess the feasibility of achieving Indonesia's net-zero emissions target by 2060. The study includes five scenarios differentiated by the availability of renewable energy technology. The advanced (ADV) scenario, utilizing nuclear power and energy storage, achieves the 100% renewable energy target by 2060 at the lowest cost. However, the costs of the conservative (CON) and moderate (MOD) scenarios are not significantly higher. Decommissioning fossil fuel power plants and increasing renewable energy infrastructure are necessary for Indonesia to achieve its net-zero emissions target. Based on the simulation, biomass energy is least favorable, and solar energy is an option only when other renewable energies have reached their maximum potential capacity. Furthermore, nuclear energy and energy storage are crucial for Indonesia to reach its renewable energy target.

Summary: Hydrogen-based energy carriers are expected to play an important role in reducing residual carbon dioxide emissions, but their competitiveness and complementarity with other mitigation options are still uncertain. However, under stringent mitigation scenarios or in the absence of carbon capture and storage, hydrogen-based energy carriers have the potential to account for 10-15% of total energy demand.

Summary: Many countries have implemented stringent climate policies to reduce the risks of climate change, but these policies can impose additional costs on households and the poor, threatening their well-being. However, the impact of climate policies on poverty and welfare loss is often overlooked. This study analyzes the distributional effects and poverty implications of carbon pricing in China during the transition to carbon neutrality and the long-term goals of the Paris Agreement. The findings suggest that climate change mitigation efforts would not significantly hinder poverty alleviation in China.

Summary: Thailand's NDC aims to reduce 20 to 25% of greenhouse gas emissions by 2030. However, achieving more stringent reduction targets requires significant transformations in Thailand's fossil fuel-dependent energy system. A computable general equilibrium analysis reveals that renewable energy and carbon capture and storage technologies will play a major role in the power generation mix by 2050 if 100% GHG emission reduction is to be achieved.

Summary: Fires and their emissions have multiple impacts on the environment and society, including negative effects on human health, terrestrial ecosystems, and climate change. Previous studies focused on the influence of climate change and population growth but didn't consider the compound effects of economic development and land use change. In this research, we analyzed fire carbon emissions in the 21st century by changing five factors. Global future fire carbon emissions were found to decrease due to increased GDP per capita and improved fire management. Meteorological factors had a strong influence, with boreal forests expected to experience increased fires due to fuel dryness. This study provides valuable insights for climate change researchers to consider fire-carbon interactions and develop mitigation and adaptation plans.

Summary: This study estimates the aggregated cost of climate change by using an integrated assessment model and detailed-process-based climate impact models, along with different discount rates for market and non-market values. The results show that setting a lower discount rate for non-market value, i.e., a higher estimate for future value, makes the aggregated cost of achieving the Paris Agreement economically reasonable.

Summary: Many countries have set ambitious long-term emissions reduction targets to align with the Paris Agreement, but such efforts may have adverse effects on poverty through economic channels. Our study shows that climate change mitigation, excluding climate change impacts, has the potential to increase global poverty by 69 million (19%) in 2030, mainly driven by income and price changes. However, measures such as emission regulations and enhanced energy efficiency standards can help mitigate this adverse side effect.

Summary: Reducing meat consumption, especially ruminant meat, can significantly reduce greenhouse gas emissions, agricultural land use, and improve human health. This study examines the potential of forage fish as a substitute for ruminant meat by 2050 and finds that it could replace 10% of global ruminant meat consumption, leading to reductions in GHG emissions and land use by up to 15% and 10% respectively. Additionally, the consumption of forage fish can increase intake of essential nutrients in deficient regions. Effective fisheries management and sociocultural acceptance are key to realizing the potential of forage fish.

Summary: Efforts to reduce emissions in the agriculture, forestry, and land-use sector are crucial for achieving climate change mitigation goals, but their impact on food security is not well understood. This study, using global agroeconomic models, examines how afforestation, bioenergy, and non-CO2 emissions reductions could affect agricultural prices and the risk of hunger. Results show that afforestation has a significant impact on food security compared to non-CO2 emissions policies, highlighting the need for coordination in emissions reduction and agricultural market management policies.
