China is the world's largest energy consumer and CO2 emitter. Cities contribute 85% of the total CO2 emissions in China and thus are considered as the key areas for implementing policies designed for climate change adaption and CO2 emission mitigation. However, the emission inventory construction of Chinese cities has not been well researched, mainly owing to the lack of systematic statistics and poor data quality. Focusing on this research gap, we developed a set of methods for constructing CO2 emissions inventories for Chinese cities based on energy balance table. The newly constructed emission inventory is compiled in terms of the definition provided by the IPCC territorial emission accounting approach and covers 47 socioeconomic sectors, 17 fossil fuels and 9 primary industry products, which is corresponding with the national and provincial inventory. In the study, we applied the methods to compile CO2 emissions inventories for 24 common Chinese cities and examined uncertainties of the inventories. Understanding the emissions sources in Chinese cities is the basis for many climate policy and goal research in the future

Technological advancement in industrializing cities is critical for reducing CO ₂ emissions while maintaining economic growth.

Science assessments indicate that human activities are moving several of Earth's sub-systems outside the range of natural variability typical for the previous 500,000 years (1, 2). Human societies must now change course and steer away from critical tipping points in the Earth system that might lead to rapid and irreversible change (3). This requires fundamental reorientation and restructuring of national and international institutions toward more effective Earth system governance and planetary stewardship.

The governance of climate change has traditionally been conceived as an issue of international co-operation and considered through the lens of regime analysis. Increasingly, scholars of global governance have highlighted the multiple parallel initiatives involving a range of actors at different levels of governance through which this issue is being addressed. In this paper, we argue that this phenomenon warrants a re-engagement with some of the conceptual cornerstones of international studies. We highlight the conceptual challenges posed by the increasing involvement of non-nation-state actors (NNSAs) in the governance of climate change and explore the potential for drawing from alternative theoretical traditions to address these challenges. Specifically, the paper combines insights from neo-Gramscian and governmentality perspectives as a means of providing the critical space required to generate deeper understanding of: (a) the nature of power in global governance; (b) the relationship between public and private authority; (c) the dynamics between structure and agency; and (d) the rationalities and practices of governance.
