According to data released by the capital city on January 24, about six percent of registered cars in 2021 were eco-friendly -- hybrid, electric and hydrogen vehicles. Hybrid cars increased by 23.08 percent, electric cars surged by 73.4 percent and hydrogen cars increased by 46.3 percent from a year ago. The percentage of diesel cars decreased by 2.1 percent.
"We will try to build a customized transportation system through meticulous automobile management and adoption of preemptive policies that focus on eco-friendly vehicles," Seoul's urban transport bureau director Baek Ho was quoted as saying. The capital city said that the demand for automobiles is changing from internal combustion engine types to eco-friendly vehicles.
Seoul is planning to operate some 1,000 hydrogen buses and build 11 hydrogen fueling stations by 2025 to reduce carbon emissions. In January 2021, the capital city also adopted 27 electric buses to replace diesel buses. South Korea, which had a renewable energy dependency rate of 4.8 percent in 2020, is trying to achieve net-zero carbon dioxide emissions by 2050.
