随着互联网的发展,快递以及外卖给学生群体的校园生活带来便捷,产生的外卖以及快递的包装垃圾也给校园的低碳建设带来阻碍。选取阳江地区某高校学生作为调查对象,通过调查问卷了解学生外卖、快递次数及其垃圾处理情况,根据生命周期评价法计算所产生的碳足迹,在碳足迹的基础上结合问卷调查结果,分析它们的碳足迹对环境的影响以及低碳校园建设中存在的问题,并提出相应的建议,以鼓励师生积极参与到低碳校园建设中,为其他高校的低碳校园建设提供参考。 相似文献

定量分析碳排放驱动因素,对优化能源结构、调整产业结构、推进技术进步、发展低碳经济具有重要的理论和现实意义.利用碳排放估算模型,测算了黑龙江省1995-2012年能源消费的碳排放量.基于扩展的STIRPAT模型,实证研究了各驱动因子对碳排放总量的影响及其驱动程度.结果表明,能源结构、经济发展水平、城市化率、人口总量对碳排放量有正向驱动作用,而产业结构、能源强度对碳排放总量的增加具有抑制作用,提出有效促进能源消费结构优化、加大产业结构调整、大力推进技术创新是实现黑龙江省低碳经济发展的有效路径. 相似文献

Community-level initiatives will play a key role in meeting greenhouse gas reduction targets. This paper examines the experience gained in applying a targeted social marketing approach to foster local-scale community pro-environmental behavioural change in the City of York, UK. This involved determining the neighbourhood carbon footprint, identifying residents that had access to appropriate infrastructure and were receptive to green issues. Six community teams were recruited from the selected neighbourhoods and provided with information, advice and mentoring on how to reduce their carbon footprint over a six-month period. A statistically significant reduction in carbon emissions was achieved. Each participant achieved a mean reduction in their carbon footprint of 2.0 tonnes of CO2e/year. The largest reductions were achieved in the areas of shopping and home energy. In addition, it helped to foster community spirit. Based on the experience gained from implementing this approach, a cost-effective model of community engagement is proposed. 相似文献

The present research introduces a well to wire pseudo comprehensive carbon footprint model for combined cycle power plants. The mentioned model integrates land use change model, operational model and transmission and distribution model into one comprehensive model. The parameters which their effects are considered in the integrated model are: fuel type, fuel transmission type, emission for fuel extraction and processing, own consumption of the plant, degradation, site ambient condition, transmission and distribution losses. For quantifying the effectiveness of each parameter, sensitivity analyses based on different life cycle scenarios are performed. The result shows that the effect of land use change is negligible. The carbon footprint of electrical energy produced in combined cycle plant until it is delivered to the end users varies from 321 to 522 g CO2 eq/kWh. 相似文献

The release of carbon dioxide from the burning of fossil fuels is believed to be responsible for climate change. In the UK, road transport emits 22% of the total output of carbon dioxide. This study applies the ecological footprint to Merseyside to ascertain the global environmental impact of passenger transport (expressed in hectares). Results show that car travel has a footprint of 704 000 hectares, which is 87% of the total footprint. It is demonstrated in scenarios that Policy initiatives involving the Local Transport Plan will cause the footprint to increase. It is also shown that individual behaviour could be influenced when highlighting the impacts of different modes of transport along the same route. By using the ecological footprint in educational programmes, the effect can be shown of carbon emissions and land appropriation on the 'school run'; these issues could be promoted alongside others such as health, safety, congestion, global equity and fairness. 相似文献
