摘要:

作为中国应对气候变化的关键领域,特大城市家庭碳排放研究具有重要意义。对于西安市家庭而言,其低碳消费行为特征及关键影响因素与其特定的资源禀赋、经济水平和社会发展特征息息相关。本文基于2015年西安市家庭能源消费问卷调查数据,通过描述统计、多元回归分析发现,家庭户均年碳排放量为12 111.87kg,居住与交通比例为4∶1,其中生活用电占居住碳排放近41%,私人汽车则为交通出行碳排放最大贡献者。家庭属性、个人属性、消费行为、住房特征及周边公共服务设施等对碳排放有显著影响,但不同影响因素作用方向及效果存在差异,实证结果有利于为城市政府有效能源规划及节能减排管理提供理论参考。

Abstract:

As critical areas in the response to global climate change,there is a great need to research household carbon emissions in megalopolises,such as those in China. Across Xi'an households there is a deep relationship between key impact factors and low levels of economic development. Here we estimated characteristic and impact factors of residential carbon emissions for 915 households in Xi'an using survey data from micro-family activities in 2015. We found that households produce 12 111.87kg CO2 every year. The ratio of family living to transportation is 4∶1. Electricity accounts for 41% of residential energy consumption. The car is the driving factor of carbon emissions in family transportation. The highest income group showed a strong willingness to buy green products and improve environmental quality. In summer,the temperature setting of air-conditioners is 23℃,lower than the national recommended standard. After housing spaces increase from 60m2 to 80m2,carbon emissions rise considerably. As the distance between community and shopping malls becomes longer,more households choose car travel. It is not only the pursuit of modern life,but also once a car has been acquired,people become dependent on it for virtually all journey purposes. Migrant families choose to improve their living environment and at the same time consume more resources and increase their carbon emissions. Our society is still emphasizing ‘meet people’s basic needs’ in Xi'an,so the city cannot achieve abstemious society completely. These results will guide the effective pathway to reducing residential carbon emissions and help design policies to develop low-carbon lifestyles in China’s megacities.
