Transportation emissions remain a huge struggle for states and countries around the globe. Even regions that are otherwise pretty green tend to miss the mark, like California, which saw its transportation emissions rise even as the state’s overall greenhouse gas emissions fell to record lows. But several countries in Central and South America are hoping to buck the trend with new fleets of electric buses. In Costa Rica, where the transportation sector is responsible for 68 percent of emissions, the government is planning to add electric buses for a trial run in 2019. Chile is also building up its electric buses, with its first two vehicles hitting the streets of Santiago last fall, with many more are on the way. Medellín, Colombia will introduce 500 electric taxis this year alone, with the ultimate goal of adding 1,500 by 2020.
