Abstract

The number of Life Cycle Assessment studies in urban public transportation focusing on modals that aim to reduce global warming impacts are increasing significantly in the last few years. These studies suggest that the insertion of green modals on local public transportation systems could be a solution to reach sustainable development. However, the impact of this insertion in developing countries is not clear yet. Then, our main objective is to evaluate the environmental impact of an emerging city’s public transportation system, considering different public policies. Consequently, we conducted a Life Cycle Assessment study considering the transitions from diesel to biodiesel buses and electric buses from 2020 to 2030. Three scenarios were performed, with the following criteria: battery changes, the increase of biodiesel percentage used in the fuel mix and buses’ expected average lifespan transitioning to electric vehicles. The results show a decrease in impact by 2030 in analysed scenarios and may support policymakers to decide whether to focus on a short-term or long-term transport policy to reduce the fleet sustainable impact. Particularly, electric buses emerge as an option to reduce environmental impacts in the public transportation system in Porto Alegre, Brazil.

城市公共交通从传统公交转向电动公交的环境评价:一个案例研究

近年来，以减少全球变暖影响为目标的城市公共交通生命周期评估研究的数量显著增加。这些研究表明，在当地公共交通系统中引入绿色模式可能是实现可持续发展的一种解决方案。然而，这种插入对发展中国家的影响尚不清楚。然后，我们的主要目标是评估一个新兴城市的公共交通系统的环境影响，考虑到不同的公共政策。因此，我们进行了一项生命周期评估研究，考虑到从2020年到2030年从柴油到生物柴油公交车和电动公交车的过渡。我们执行了三种情景，标准如下:电池更换、燃料组合中生物柴油使用百分比的增加以及公共汽车向电动汽车过渡的预期平均寿命。结果显示，在分析的情景中，到2030年，影响将会减少，这可能会支持政策制定者决定是关注短期还是长期的交通政策，以减少车队的可持续影响。特别是，在巴西的阿雷格里港，电动公交车成为减少公共交通系统对环境影响的一种选择。
