Dynamics of carbon footprint in Guangxi Zhuang Autonomous Region
摘要
Abstract
In order to know the carbon balance of the Guangxi Zhuang Autonomous Region , IPCC method is used to estimate the carbon footprint and the amount of vegetation carbon sequestration from cement production process and energy activities , and the carbon footprint level assessment is carried out . The results show that between 1996 and 2012 , the carbon footprint grew year by year from -3 298.32 × 104 t to 24 859.66 × 104 t in Guangxi ,which increased by 853.71% . The energy carbon footprint increased by 432.91% ,cement carbon footprint increased by 372.60% , and the vegetation carbon sequestration increased by 44.77% .Carbon footprint from energy consumption account for 88.95% to 91.53% of total emissions , and cement account for only 8.47% to 11.05% . Carbon footprints per capita , per unit area and carbon emissions index increased to 749.88% ,830.60% and 769.42% , respectively . The grade of carbon footprint changed from carbon sinks to medium ,which was across 4 sub‐grades . The conclusions are as follow s :Since 1996 , the grow th of carbon footprint is fast in Guangxi . Carbon emission grow th of energy and cement is much larger than amount of vegetation carbon sequestration . The carbon footprint is mainly caused by the burning of fossil fuels . T he carbon sequestration capacity of vegetation is very strong , and it can neutralize the carbon emissions of more than a third of the carbon emissions in Guangxi . But the increase in the vegetation carbon is too small , so that more attention should be paid to the conservation of vegetation . T he carbon emissions increase is larger , w hich should arouse the attention of the relevant departments . Without considering the vegetation carbon sequestration , according to the carbon emission index from big to small order , Guangxi ranked fourteenth in 31 provinces and autonomous regions , belonging to the middle level in 2012 .关键词
