Summary: With the global commitment to reach carbon peak by 2030 and net zero by 2050, the use of coal as an energy source is encountering unprecedented challenges. The International Energy Agency (IEA) predicts that global annual coal demand will decrease from over 5640 million tonnes of coal equivalent (Mtce) in 2021 to 540 Mtce in 2050 under the net zero emission scenario, with renewable energy like solar and wind replacing most of it. Hence, the coal industry is actively searching for alternative applications to sustain its development, and nanotechnology can be a contributing factor. This article outlines the challenges and proposes a path towards commercialization in coal-based carbon nanomaterial syntheses. Coal-based carbon nanomaterials hold promise in the concept of clean coal conversion, transforming it from an energy source to a high-value-added carbon source.

Summary: A study on China's coal mine methane (CMM) emissions between 2010 and 2019 revealed that the annual emissions were estimated at 20.11 Tg with a decline trend. Factors such as the growth of CMM utilization, shift to lower-emission coal mining areas, and decrease of emission factors contributed to curbing the increasing trend of China's CMM emissions since 2012.

Summary: China's clean air actions from 2013-2020 have led to a net reduction of 2.43 Gt CO2 emissions by promoting the transformation of the country's energy system. The co-benefits of these measures far outweigh the additional CO2 emissions, signaling the significant climate benefits of tackling air pollution.

Summary: This study used the Circum-Arctic Sediment Carbon Database to reveal differences in terrOC release. The results show that terrOC release is five times larger in the Eurasian Arctic than in the American Arctic. Most of the terrOC comes from near-surface soils, while 30% comes from Pleistocene-age permafrost. TerrOC translocation varies by a factor of five between circum-Arctic regions.

Summary: Many studies have emphasized the importance of clean energy development for China's carbon peaking commitments and addressing global environmental problems. However, few studies have investigated the spatial correlation and carbon peaking process to fully understand the spatial spillover effects of carbon emissions and the urgency of emission reduction. Unexpected power cuts in 2020 have brought new requirements to comprehensively understand China's clean energy development and carbon peaking. In this study, the spatial econometric panel model and GM (1, N) are used to analyze the relationship between clean energy development, spatial carbon emissions, and the process of carbon peaking in China.

Summary: The study found that the implementation of China's CDM projects effectively reduced the carbon dioxide emissions per unit of GDP, with different types of CDM projects showing varying emission reduction effects. Furthermore, it was discovered that CDM projects in China not only reduced carbon emissions but also improved energy utilization efficiency.

Summary: Climate-oriented goals in air quality and clean energy policies can significantly reduce greenhouse gas emissions, especially by shifting to biomass cooking and addressing emissions from brick production and agricultural residue burning. Sustainable development goals connect policies addressing air quality and energy efficiency with complementary benefits for climate mitigation, but a fragmented approach across domains may hinder effectiveness in addressing short-lived climate forcers.
