Abstract: Under the background of the global economic downturn,China's economy also has declined in recent years. The GDP growth rate in China was 6.9% in 2015,lower than 7% for the first time since 1997. As a consequence,the characteristics of energy and carbon emissions from the perspectives of both supply and demand may show some new features under this new economic norm. In this paper, the energy and carbon flow chart of China in 2015 were drawn to display the flow of main types of energy in terms of energy production, energy processing, energy consumption as well as energy-related emissions based on the latest data such as China's energy balance(standard quantity)of 2015. The results show that energy consumption in 2015 was only 0.5% higher than in 2014. Due to the limitation of the development stage in China, the industrial sector accounted for 68.0% of the total energy consumption in 2015,showing a slight decrease compared with that in 2014. The carbon emissions increased by 3.7% in 2015 compared with that in 2014. Although the coal still dominates the energy structure in China,its output has continued to decline. In addition,the production of oil and gas developed stably,and the proportion of renewable electricity and other energies in primary energy production continues to rise. Energy inventory has started to decline for the first time since 2010. As for carbon emissions, the emissions from coal accounted for 82.0% of the annual carbon emissions. Thermal power and the industrial sector are the main sources of carbon emissions,with their carbon emissions accounting for 76.9% of the annual carbon emissions.
