Abstract

Abstract

Under the Dual Carbon Goals， systematically assessing the carbon footprint of China's bioeconomy is crucial for promoting sustainable development. This study employed an Environmentally-Extended Multi-Regional Input-Output （EE-MRIO） model， based on the EXIOBASE v3.9.6 database， to systematically analyze the global carbon footprint driven by China's final consumption in its bioeconomy from 2000 to 2022， including its spatio-temporal evolution and structural characteristics. The study found that the total global carbon footprint driven by China's final consumption in its bioeconomy is substantial and shows a fluctuating upward trend. Although the domestic carbon footprint has long dominated， the import carbon footprint significantly increased during the same period， indicating a growing environmental responsibility spillover effect. In terms of global carbon footprint composition， primary biotic resources have consistently been the largest source， accounting for over 60% in the long term. Bioenergy and waste valorization， along with related bio-based services， have also made prominent contributions. The domestic carbon emission structure has undergone a profound transformation. There has been an accelerated shift of hotspots from upstream sectors centered on agriculture and livestock to downstream sectors dominated by manufacturing and energy （including resource utilization）. The influence of emerging bio-based chemicals continues to grow， while biofuels show significant policy-related fluctuations. The sources of the import carbon footprint exhibit notable geographical concentration， meaning that resource-intensive， high-carbon-emission upstream production processes are mainly undertaken by developing countries， while developed countries focus more on high value-added processing and livestock product manufacturing. This study provides scientific support for the green transition of China's bioeconomy， the development of carbon accounting standards， and the coordinated governance of global supply chains.
