Abstract
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.
Highlights
Cities are the main consumers of energy and emitters of CO2 throughout the world
The International Energy Agency (IEA) (2009) estimates that CO2 emissions from energy use in cities will grow by 1.8% per year between 2006 and 2030, with the share of global CO2 emissions rising from 71% to 76%
We develop a feasible methodology for constructing CO2 emissions inventories for Chinese cities from fossil energy consumption and industrial processes, aiming at providing unified and comparable energy and emission statistics for generic Chinese cities
Summary
Cities are the main consumers of energy and emitters of CO2 throughout the world. Cities are major components in the implementation of climate change adaption and CO2 emission mitigation policies. Understanding the emission status of cities is considered a fundamental step for proposing mitigation actions. Lifestyle change and consumption growth (Hubacek et al, 2011), China is the world's largest consumer of primary energy and emitter of greenhouse gas emissions (Guan et al, 2009). According to U.S Energy Information Administration (EIA) (2010) and British Petroleum (2011), China produces 25% of global CO2 emissions, consumes 20% of global primary energy. An effective understanding of the energy consumption and emission status of common cities in China is urgently required to practice mitigate climate change
