Abstract

The 2016 baseline road and rail transportation pollutant emissions in the Philippines using a bottom-up approach are estimated at 9.212 million tons and 377 tons, respectively, while CO₂ emissions are estimated at 97.6 million tons and 62,248 tons, respectively. Road transportation activity is estimated to be 231.53 billion vehicle-kilometers, where 58% is from motorcycles. Top pollutants are CO and VOC from motorcycles, tricycles and cars. Motorcycles contribute the largest share of CO₂ emissions. NOₓ and CO are major pollutants from rail transportation. Based on these results and the assessment of selected transport projects, the government may develop policies on major emitters of criteria pollutants and carbon dioxide, aside from improvement of public transportation. Furthermore, the study is limited in using average vehicle emission factors which need updating.

菲律宾公路和铁路运输的当地污染物和二氧化碳排放量估算

采用自下而上的方法，菲律宾 2016 年的公路和铁路运输污染物基准排放量估计分别为 921.2 万吨和 377 吨，二氧化碳排放量估计分别为 9760 万吨和 62248 吨。道路运输活动估计为 2,315.3 亿车公里，其中 58% 来自摩托车。主要污染物是摩托车、三轮车和汽车产生的一氧化碳和挥发性有机化合物。摩托车的二氧化碳排放量最大。NOₓ 和 CO 是铁路运输的主要污染物。根据这些结果和对选定交通项目的评估，除了改善公共交通外，政府还可针对标准污染物和二氧化碳的主要排放者制定政策。此外，该研究使用的平均车辆排放系数有限，需要更新。
