摘要

Global shipping activity emits 938 million tonnes of carbon dioxide annually, surpassing the eighth highest emitting country.Although the impacts from the shipping industry have been investigated over the past three decades, allocating responsibilitiesremains a difficult issue. Numerous parties should share the responsibility and quantitative analysis is therefore requiredwhen considering the interaction between the global economy, shipping and ecological connectivity. Here, beginning with ourshipping emission inventory model based on satellite-observed vessel activities, we evaluated trade-embodied shipping emissionsand their impacts on human health. Combined with international trade databases, we traced shipping impacts back toresponsible bilateral trade and proposed an integrated trade–shipping–air quality–health impact nexus. Quantitative analysisshows that the US–China bilateral trade is responsible for 2.5% of the global shipping carbon dioxide emissions and 4.8% ofship-related global premature deaths caused by air pollution. Our research provides the methodology to allocate intercontinentalresponsibilities to trade pairs and ships.
