“…With the passage of time, the gap between the eastern and western regions has become larger and larger, showing a spatial pattern of more east and less west [50]. Zhang et al [51] also showed that the eastern region has the largest percentage of abandoned passenger vehicles, consistent with our results. This may be caused by the economic gap between the east and west.…”

As a polymer material, plastic is widely used in passenger vehicles for its light weight and low-cost advantages. China has accumulated a large amount of discarded automotive plastic in recent years, which has put increasing pressure on the environment and the recycling industry. A dynamic material flow model for estimating the plastic stock and waste in passenger vehicles was developed. Additionally, geospatial models were used to study the spatiotemporal evolution trend of passenger vehicle plastics. The results show: (1) passenger-vehicle plastic stock and waste in China increased rapidly from 1985 to 2019. By 2019, the passenger-vehicle plastic stock was 36.94 million tons, and the waste amount was 1.64 million tons, of which polypropylene accounted for the greatest proportion, and polyoxymethylene (POM) accounted for the least. (2) The stock and waste of passenger-vehicle plastics showed spatial dependency. (3) The spatial center of plastic waste was located in Henan Province, and the spatial center is shifting from north to south. (4) The GDP and the annual population are the main driving factors of passenger-vehicle plastic waste. This study will improve plastic waste management, resource recovery, and environmental sustainability decisions.

“…Similarly, except for wood and brick, the outflow of all materials will increase steadily, of which the most significant increase will be from steel, that is, from 19 million t in 2021 to 50 million t in 2050. This magnitude will approach steel scrap in household vehicles system, which is expected to increase to 55 million t in 2050 (Zhang et al., 2022). Therefore, increasing the use of recycled steel in end‐of‐life residential buildings can be an effective way to relieve primary steel demand and conduct the strategy of urban mining in China.…”

This study predicted the metabolic process of the residential building system in China toward 2050 by addressing the detailed provincial patterns and urban–rural disparity and the characterizing metabolisms of building materials in detail. The results show that after a rapid growth during 1980–1990, the in‐use stocks of residential buildings in China are expected to slow down in around 2030, reaching 75 billion m2 in 2050. Urban regions will account for 80% of total stocks, and provinces in the eastern and southern coastal areas will have the largest share. As demolition lags construction, the end‐of‐life residential buildings will continue to grow steadily with huge urban–rural and provincial differences, reaching 1.4 billion m2 by 2050. Regarding the metabolism of building materials, the inflow of most materials will decrease after 2030, while the outflow will increase steadily toward inflow. Based on the recycling outlook of construction and demolition waste and the corresponding environmental benefit, it is indicated that under the Chinese government's ambitious planning and vigorous promotion, prior to the middle of the century, the building system has the potential to transition to a sustainable future that meets residents’ housing needs with a remarkable decreasing input of raw materials thereby notably decreasing pressures on the environment, which will significantly benefit the goal of carbon neutrality in China.

“…The database can serve as the foundation for analyzing energy consumption and material cycles. The projection of vehicle stocks could offer valuable information on urban mining (Zeng et al 2020;Zhang et al 2022), material demand (Aguilar Lopez et al 2023Billy and Müller, 2023;Xu et al 2020), and energy consumption (Bu et al 2021;Zheng et al 2015) to governments and related industries. Currently, most studies on vehicle ownership projection in China focus on national and provincial scales.…”

Unequal outcomes resulting from urbanization can pose a significant challenge to sustainable development. Vehicles are an important urbanization dimension as a critical component of urban infrastructure by providing mobility and accessibility to social services. China’s vehicle ownership (referred to as in-use vehicle stocks) has been growing quickly since 2000, but its per capita stocks are still much lower than that in developed economies. This raises the question of whether and when China’s vehicle stocks will reach a peak level close to that in the developed countries. By analyzing vehicle stocks in 283 Chinese cities during 2001–2018, we have the following findings: (1) vehicle stocks are predominantly distributed in northern and eastern coastal cities and provincial capital cities; (2) inequality in vehicle ownership rates between cities shows a declining trend at both national and region scales; (3) the growth of vehicle ownership rates follows an S-shape curve and most cities are still at the early stage of motorization; (4) China is likely to have a lower saturation level of vehicle ownership rate. These results could help to accurately forecast future vehicle demand in China, estimate the resulting environmental impacts, and explore strategies to achieve carbon neutrality in transportation.
