Summary: This article analyzes the recognition of Indigenous Peoples' rights in Nationally Determined Contributions (NDCs) under the Paris Agreement. Although the number of NDCs related to Indigenous Peoples is increasing, there are doubts regarding their sincerity and commitment to implementation. Therefore, states need to make more significant efforts to ensure that NDCs take a rights-based approach and contribute to strengthening Indigenous Peoples' role and say in climate governance.

Summary: The carbon tax, as an environmental regulation tool, can promote technological progress, which has been overlooked in previous evaluations of its economic impact. This study uses the Generalized Method of Moment model to examine the effect of an environmental tax on total factor productivity and energy efficiency. The findings suggest that a carbon tax policy initially negatively impacts GDP but can become positive in the later stages due to technological progress and a transition to low-carbon industries.

Summary: China implemented the environmental protection tax (EPT) in 2018 to address severe air pollution, while carbon tax (CTX) has been identified as an effective measure for climate change mitigation. This study compares the separate and combined effects of EPT and CTX policies in 2030 using a multiple-province computable general equilibrium (CGE) model. The results indicate that while EPT has limited impact on air pollution and CO2 reduction, CTX effectively targets CO2 emissions and reduces air pollutants. Integrating these policies enhances emission reduction efficiency, with CTX complementing EPT. However, economic implications and equitable burden distribution need to be carefully considered.

Summary: Carbon tax is crucial for achieving carbon reduction goals. This study examines the impact of carbon tax on China's energy sector and finds that it effectively reduces CO2 emissions. The results show that reducing coal and thermal power plant usage contributes significantly to emission reduction, and carbon tax can have a double dividend effect under certain scenarios.

Summary: This study finds that climate actions in China have mainly focused on CO2 mitigation and have not comprehensively studied the impact of non-CO2 greenhouse gases. By developing a multi-sector dynamic model, we compare the economic impact of CO2-only mitigation with a multi-GHG mitigation policy that also prices non-CO2 GHGs. The results show that the multi-GHG approach significantly reduces the marginal abatement cost and economic loss compared to a CO2-only scenario.

Summary: This study identified AKINbetagamma-1 protein kinase as a negative regulator of maize tolerance to lead (Pb) and revealed its involvement in pectin metabolism and nitrogen compound response. Three variants in the promoter of ZmAKINfi gamma 1 were found to affect its expression and Pb tolerance in maize lines. Understanding the ZmAKINfi gamma 1-mediated Pb tolerance mechanism provides insights for breeding Pb-tolerant maize varieties and phytoremediation of Pb-polluted soils.

Summary: In the process of addressing climate change, China is projected to become a major bioenergy consumer. However, this may lead to global land-use changes, food security concerns, and greenhouse gas emissions. The Global Biosphere Management Model (GLOBIOM) was used to study the effects of different bioenergy import strategies in China. The results indicate that strict biomass import regulations could result in substantial forest conversions, while open trade environments may cause significant shifts in trade flows and land-use changes in other regions. Nonetheless, an economically optimized biomass import portfolio for China has the potential to mitigate sustainability trade-offs.

Summary: Over the past decade, thermal power plants in China, the largest energy infrastructure in the country, have consumed half of China's coal and posed threats to air quality, human health, and socioeconomic development. To alleviate these impacts, China has implemented a series of control policies, leading to significant reductions in air pollutant emissions. However, the effects of ultra-low emissions (ULE) policies on air quality, health, and cost benefits are still not well understood. This study estimates the improved air quality, health benefits, and economic gains achieved through ULE standards in the thermal power sector by employing a measure-specific approach. The results indicate that all control measures have resulted in reduced air pollution, with renovating pre-existing units being the most effective measure. Compared to not implementing the ULE policy, the implementation of these measures could lead to decreased population-weighted average PM2.5 and O3 concentrations, as well as the avoidance of 67,831 premature deaths nationwide. Additionally, the study demonstrates a net economic benefit of 109.92 billion Yuan (in 2015 value) in China when considering health benefits and costs due to control measures. These findings highlight the importance of considering health impacts in policy-making and provide possible strategies for further promoting control measures in China and tightening emission standards for thermal power plants worldwide.

Summary: This study examined the internal mechanism, spatiotemporal correlation, and allometric characteristics of economic development and carbon emissions in the Yangtze River Delta urban agglomeration (YRDUA) using panel grey relational model and Driscoll-Kraay estimation method. The results showed a positive correlation and coincident distribution patterns between economic development and carbon emissions, with the economic development-carbon emissions vertical allometric growth coefficient showing a trend of first increasing and then decreasing. Per capita GDP, industrial structure, and energy structure were identified as boosting factors, while population density and environmental regulation played a restraining role in the allometric growth coefficient. Trade openness had a negative effect in 2010-2015 but became a promoting factor in 2016-2020. The findings provide valuable insights for achieving low-carbon city development goals in urban agglomerations.

Summary: Household solid fuel use is detrimental to health and the environment. The Indian government's PMUY subsidy has successfully promoted the adoption of LPG by millions of households. However, there is limited understanding of the decision-making process to reduce solid fuel use after transitioning to cleaner fuels. This study found that factors such as household wealth, social status, education level, and the prevalence of LPG use in the village are positively associated with LPG consumption and the discontinuation of solid fuel use. On the other hand, factors such as distance to LPG refill delivery, household size, and the PMUY subsidy are negatively associated with the share of LPG use.

Summary: Economic costs are a major political obstacle to investing in climate change mitigation and adaptation measures. The method of financing plays a crucial role in determining public opposition to government green investments, with debt financing being less opposed than broad-based taxes. This study suggests that credit market tools, such as green bonds and debt for climate swaps, can be politically efficient in increasing support for green financing. Carbon taxes and wealth taxes are found to be the most preferred options.

It finds that the energy trade linkages between China and 153 other countries are complex and unstable, with short periods of trade with many countries. Geopolitically risky regions, such as the Middle East and Africa, have the lowest trade stability. Climate risks have significant effects on energy trade stability. The paper proposes several policy options to improve energy trade stability in China, with special attention to increasing global climate risks.

Building on political economy analysis and five case studies of independent producer projects from Ethiopia, it seeks to understand the root causes of the protracted delays and limited extent of procurement by independent producers. The key contestations lie in managing long term contracts, risk, uncertainty and in developing the institutional and human capacity to transition.
