“…Early studies primarily focused on carbon emission measurement methods and the overall CE of urban transportation systems [2,10]. As for the carbon emission calculation models, they are mainly divided into LEAP, VT-Micro, MOVES, COPERT, HBEFA, multimodelling-based Framework and carbon footprint [11,12], and some models that use artificial intelligence for carbon emission calculation and prediction [13][14][15][16][17][18]. In recent years, with increased societal demand for carbon neutrality and green transportation, researchers have gradually turned their attention to the influence of different periods on CE.…”

This study aims to propose a comprehensive framework for measuring CE in IPTUA, taking into account both regular and holiday periods. The Low Emissions Analysis Platform (LEAP) is employed to model the CE and improvement methods for the LEAP are proposed. Using a measurement framework combined with Baidu migration data, the CE from inter-city passenger transportation (IPT) between five main cities in the Guanzhong Urban Agglomeration (GUA): Xi'an (XA), Tongchuan (TC), Baoji (BJ), Xianyang (XY), and Weinan (WN), are calculated for the year 2021. This includes the CE from private car travel, highway bus travel, and railway travel. A dual-layer prediction framework is used to forecast future CE, and carbon peak predictions for IPT in the GUA under different policy and technological improvement scenarios are conducted. The results indicate that carbon peak status will be achieved in all scenarios by 2029. Furthermore, both policy and technological scenarios have a significant impact on reducing total CE. Under the policy scenario, CE decreased from the actual value of 7,714,864.408 tons to 7,564,746.75 tons. Under the technological scenario, CE from regular national and provincial roads (RNPR) decreased by 236,542.567 tons with a 10% reduction in energy consumption, and CE from highway private car travel decreased by 528,427.9295 tons. Meanwhile, with an annual 1% reduction in energy consumption, CE from RNPR decreased by 189,234.05 tons, and CE from highway private car travel decreased by 422,742.3 tons. From the reduction perspective, a one-time 10% reduction in energy consumption for private cars results in a greater reduction in CE. However, gradually reducing private car energy consumption is more feasible in practice. This study provides a comprehensive and accurate assessment of CE in IPT during different periods, offering a scientific basis for formulating carbon emission reduction policies.

“…The long-term coal-based energy consumption structure has caused China to face serious environmental problems and enormous energy security challenges [8,9]. It is urgent to vigorously develop new low-carbon energy sources and change the energy structure [10,11]. However, there is still a great uncertainty in the knowledge of non-conventional energy development in China.…”

The development of non-conventional energy sources is not only an important guarantee for national energy security but also a key support for the realization of carbon peaking and carbon neutrality goals. However, there is limited knowledge of the spatial and temporal patterns and changing characteristics of green energy development in China. Here, based on the energy production and consumption data of the last decade, we combined the gravity center model and statistical model to assess the spatial and temporal patterns of non-conventional energy in 31 provinces of China. The research results show: (1) under the impetus of the development of green low-carbon and ecological civilization strategy, the rate of increase in the production of non-conventional energy in China and the proportion of it increase year by year, and the energy structure obviously presents the characteristics of being low-carbon and cleaner. (2) For the spatial patterns of non-conventional energy development, due to the development of wind power and photovoltaic constraints by natural resource conditions and technology, their development trend is best in northeast, north, and northwest China. (3) The generation of PV and wind power is dominated by northwest China and north China, and the generation of nuclear power is dominated by southeast China, whereas the consumption is dominated by east China and central China; there is an obvious spatial imbalance between non-conventional energy production and consumption. (4) The proportion of photovoltaics in non-conventional energy production has increased significantly over the 2010–2020 period, which is the main driver of the overall shift in the gravity center of non-conventional energy production towards the northwest region of China. (5) In recent years, the gradual transfer of industries from the east to the central and western regions of China and the improvement in the economic level of the western regions have led to an increase in energy production and consumption, promoting a shift in the gravity center of energy production and consumption to the west. Overall, the structural transformation of China’s energy production and consumption (from a high-carbon black structure to a low-carbon and carbon-free green structure) is progressing, and some provinces have achieved significant results, presenting a non-conventional energy industry in accordance with local conditions and the development trend of the non-conventional energy industry.

This study examines the compatibility of the EU’s current 2050 clean energy transition plan, aiming to increase the share of renewable power generation to 80%, with mineral and energy security in the EU, acknowledging the interplay between these security aspects when dealing with metal-intensive energy systems. It also explores the potential advantages of an alternative electricity mix that combines the existing renewable generation share with expanded nuclear energy capacity. The results demonstrate that the planned renewable-intensive electricity mix requires substantially higher quantities of metals to increase and sustain electricity production capacity than the alternative nuclear-intensive system. This is not only the case in terms of volume requirements, which is already evident from the existing literature, but also in terms of value and import requirements. Further, our results reveal that the bottleneck risks in the planned renewable-intensive system are primarily associated with insufficient mining of essential metals inside the EU. In contrast, the bottleneck risks in the nuclear-intensive system are primarily associated with lack of processing inside the EU. Based on the assumption that acquiring relevant mineral reserves and mining capabilities may be more challenging than acquiring new processing capacities, this suggests that the planned renewable-intensive system may come with more serious bottleneck risks than an alternative nuclear-intensive system. Overall, this study leads to the conclusion that a nuclear-intensive electricity mix could offer greater metal-related energy security than the planned renewable-intensive system.
