Show moreEnergy-related CO2emissions in China have been extensively investigated. However, the mechanisms of how energy-related emissions are driven by inter-sectoral linkages remains unexplored. In this paper, a subsystem input-output model was developed to investigate the temporal and sectoral changes of emissions in China from 1997 to 2012. We decomposed total emissions into internal, spillover, feedback, and direct components. Our results show that the equipment manufacturing, construction and services sectors are the main sources of emissions during the whole period, which have a larger spillover component, primarily through indirect upstream emissions in the heavy-manufacturing, transportation, and power sectors. The emissions from the power and transportation sectors are dominated by direct rather than the spillover emissions. The shares of the feedback and internal components in the heavy manufacturing sectors were significantly higher than those of other sectors. Our results suggest that further addressing carbon emissions along the supply chain of equipment manufacturing, construction and services sectors, and improving technologies in the heavy manufacturing and power sectors holds important future opportunities for curbing the rapid growth of carbon emissions in China.

Show moreAs evidenced by Goal No. 14 of the UN's Sustainable Development Goals, the importance of oceans governance as a matter of global policy can hardly be overstated. The unsustainable uses of their resources could lead to serious consequences, not only for coastal communities, but remote landlocked countries as well. This special section aims to take the international community's clarion call for effective norms, institutions, and multi-stakeholder cooperation back to the oceans through three topical case studies. Each in its own way illustrates humanity's high stakes in blue growth, offering recommendations on how states and governments must craft coherent, effective, and actionable policies to make sustainable oceans governance a reality. Claire van der Geest's article opens the special section with a focus on the Indian Ocean and the need to redesign its fisheries governance. Hongzhou Zhang and Fengshi Wu subsequently investigate two of the most significant structural shifts of China's marine fisheries sector in the past decades, namely, going outward and focusing on high market value species. James Malcolm concludes the special section by switching attention to small island developing states, arguing that sustainable oceans governance for them represents not ‘only’ an environmental or economic concern, but indeed a matter of national security.
