We propose a dust‐event detection and tracking procedure based on air quality data from the ground monitoring network by detecting temporal and spatial change‐points in PM10 concentration. It supplements the existing remote sensing based approach with high temporal resolution and better weather adaptivity. Applications of the procedure on the labeled data showed its having high discriminating power for dust events, pollution events, and clean periods. Our study finds changing correlation patterns between PM10 and other air pollutants at the start of the dust events, which are utilized to enhance the discriminating power of the dust‐event detection procedure. The detection and tracking procedure allows the construction of transport networks of the dust‐events as well as the identification of the source regions and the transportation pattern, and assess the intensity and severity of the dust‐events in North China. Our analysis find the dust‐events contributed to 23.3%–34.6% for PM10 and 18.2–33.2% for PM2.5 in the source regions and 2.0%–7.3% and 0.8%–4.0%, respectively, in the down‐stream provinces in the spring season from 2015 to 2020.

“…By building 5,000 mu of carbon sink forest, the 2010 UN Climate Change Tianjin Conference can achieve "carbon neutralization" because all 12,000 tons of carbon dioxide emitted by the conference can be absorbed by the carbon sink forest in the next 10 years. Since then, the 2014 APEC meeting in China (Tong et al, 2020) and the 2016 G20 summit in Hangzhou, China (Colin, 2016), have achieved "carbon neutrality" through afforestation. In 2022, the Winter Olympic Games held in Beijing minimized carbon emissions through low-carbon venues, low-carbon energy, low-carbon transportation, low-carbon office, and other measures.…”

Carbon footprint and emission reduction potential of the artwork auction market

Greenhouse gas emissions from human activities have become the leading cause of climate problems. Reducing greenhouse gas emissions from human economic activities and realizing carbon neutralization are the main means of sustainable economic development. Among them, carbon emission reduction of large-scale activities including auctions bears the brunt. Through the emission factor method, this paper estimates the carbon footprint of a typical artwork auction and divides the auction market into different sizes, according to the average round-trip distance of the number of participants. The results show that a typical 3-day medium-sized artwork auction with 500 people’s carbon footprint is about 270 tons of carbon dioxide. The traffic carbon emission of participants accounts for a large proportion of the total carbon footprint, particularly composed of the traffic carbon emissions of a small proportion of long-distance participants. Therefore, the transition from offline to virtual artwork auctions can significantly reduce the carbon footprint by 90%–95%. We put forward suggestions on improving the auction carbon footprint accounting process and industry carbon neutralization system, and promoting the development of relevant technologies for the virtual artwork auction market.

“…The rapid development of the economy over recent years has catalyzed the deterioration of the ecological environment, mainly reflected in atmospheric pollution, climate change, global warming, and so on. Various countries have realized that these severe events are related closely to the carbon emission, and then they have begun to launch the carbon emission reduction scheme actively [1]- [3]. For example, more than 150 countries and the European Economic Community (EEC) jointly signed the United Nations Framework Convention on Climate Change (UNFCCC) in 1992.…”

“…Recently, considerable effort has been devoted to exploring contract design problems for the low-carbon supply chain [13], [14], in which several contracts except simple wholesale price contract can help supply chain achieve the perfect coordination. As discussed in the relative literature [15]- [17], the primary advantages of the simple wholesale price contract are (1) to facilitate the management, (2) to reduce operating costs and adjust the inventory level effectively, and (3) to grasp the market situation quickly and flexibly. Given its advantages, it is meaningful to design the extended wholesale price contract to coordinate the low-carbon supply chain and improve economic performance as well as the environmental benefit.…”

This paper is contended with the joint emission reduction and pricing decision problems, as well as coordination contract design issue for a class of low-carbon supply chain system. Here, the evolution of emission reduction level is characterized by a linear differential equation. Also, product demand depends on emission reduction level, promotional effort, and retail price in a separable multiplicative way. By considering an optimal control model of the low-carbon supply chain, differential game theory is used to obtain the optimal joint emission reduction efforts, pricing strategies, and the optimal emission reduction level in different decision systems. Subsequently, attention is focused on the design of new coordination contract with the fixed or varied wholesale price such that, under the dynamic decision perspective, supply chain system can realize the win-win situation of economy and ecology, as well as the profits of individual members are Pareto improvement. Finally, several numerical examples are given to show the validity and feasibility of the presented results.
