宁波市交通碳排放测算与分析

Measurement and Analysis of Traffic Carbon Emission in Ningbo City

摘要: 随着全球气候变化问题日益严峻，交通领域作为碳排放的主要来源之一，受到越来越多的关注。本文以宁波市为研究对象，通过对交通碳排放的测算与分析，探讨了宁波市交通部门的碳排放现状。本文基于宁波市2021~2023的相关统计数据，分别利用行驶里程法、周转量法、机场起降法三种碳排放测算方法计算了宁波市2021~2023年道路交通、铁路交通、城市轨道交通、水路交通和航空交通的碳排放量。结果显示，道路交通仍是交通碳排放的主要来源，通过对不同交通方式的碳排放强度进行对比分析，发现公共交通工具(如地铁)的单位碳排放量明显低于私家车和货车。最后，结合中国整体碳排放目标与政策，提出了降低宁波市交通碳排放的若干建议。

Abstract: With the increasingly serious problem of global climate change, the transportation sector, as one of the main sources of carbon emissions, has received more and more attention. This paper takes Ningbo City as the research object, through the calculation and analysis of traffic carbon emissions, discusses the current situation of traffic carbon emissions in Ningbo City. Based on the relevant statistical data of Ningbo City from 2021~2023, this paper calculates the carbon emissions of road traffic, railway traffic, urban rail traffic, water traffic and air traffic in Ningbo City from 2021~2023 by using three carbon emission measurement methods, namely mileage method, turnover method and airport take-off and landing method. The results show that road traffic is still the main source of transport carbon emissions. Through comparative analysis of carbon emission intensity of different modes of transport, it is found that the unit carbon emission of public transport (such as subway) is significantly lower than that of private cars and trucks. Finally, combining with China’s overall carbon emission targets and policies, this paper puts forward some suggestions to reduce the carbon emission of Ningbo’s transportation.
