“…6 ), thus reflecting the effectiveness of the Green Channel’s construction in promoting trade exchanges between Central Asian countries and other countries along the B&R. The per capita ecological resources of Bhutan and Mongolia rank first and second, respectively, among the countries along the B&R (Yan et al 2022 ). In terms of ecosystem types, in Bhutan, ecological resources are dominated by forestry resources; in Mongolia, ecological resources are dominated by grassland resources (Du et al 2022 ). From 2013 to 2019, the proportion of the trade volumes of animal husbandry products in Mongolia and forestry products in Bhutan both increased significantly (Fig.…”

The Belt and Road Initiative (BRI) was designed to promote economic and trade cooperation between countries along the Belt and Road (B&R), specifically by building an international trade network. Ecological resources are the basis for human survival. Countries along the B&R transform ecological resources into ecological products by production activities. These products can then be used for trade, thereby driving the countries’ economic development. This study uses net primary productivity (NPP) as a unified measure of ecological products, and explores the pattern changes of ecological product trade in countries along the B&R, from 2013 to 2019 (from the BRI proposal to the outbreak of COVID-19). The purpose of the study is to reveal the impact of the BRI on the trade of ecological products. The results show that (1) the trade scale of ecological products in the B&R region has changed significantly. The total volume of traded ecological products increased from 2071.74 to 2631.00 TgC. This represented an increase of about 26.99%, or 7.41% higher than the global average. (2) The spatial distribution pattern of ecological product trade did not change significantly in countries along the B&R. However, the gravity centers of the total and net trade volume of ecological products moved 120.74 km to the northeast and 392.98 km to the southeast, respectively. (3) The trade structure of ecological products in the B&R region, six sub-regions, and most countries remained relatively stable. Only the proportion of the livestock products trade in Mongolia and the proportion of the forest products trade in Bhutan have increased significantly. This finding suggests that the strength and breadth of the construction of unimpeded trade in countries along the B&R still need to further strengthened, in order to accelerate the realization of the vision of the Green Silk Road.

Heavy-duty diesel trucks (HDDTs) have caused serious environmental pollution in China. Accurate estimation of their pollutant emission characteristics is essential to reduce emissions and associated environmental and public health impacts. We developed localized emission factors and a high-resolution emission inventory of HDDTs in Northeast China, based on on-board test, Guidebook and international vehicle emission (IVE) model. The results show that the total emissions of CO, NO, NO 2 and PM from HDDTs in Northeast China in 2020 were 172.2 kt, 531.5 kt, 11.2 kt and 921.4 t, respectively. In terms of spatial distribution, emissions decreased from the city center to the city fringe. Temporally, the NOx emission variation curves of different types of roads presented a "single-peak" emission characteristic, which was different from the peak of tra c ow. We further developed three emission reduction scenarios to analyze the pollution reduction under different policies. Scenario analysis shows that elimination of HDDTs that follow the old China III emission standard and installing tailpipe treatment devices are the most effective pollutant reduction measure. The reduction percentages for CO, NO, NO 2 and PM ranged from 62.9-83.89%. The results of our study could inform policymakers to devise feasible strategies to reduce vehicle pollution in Northeast China.
