Kumho Petrochemical will convert all of its corporate vehicles to eco-friendly cars by 2030, the refiner said Thursday. The transition is part of the Korean-type pollution-free vehicle conversion 100 (K-EV100) program, a green initiative organized by the Ministry of Environment and the Korea Automobile Environment Association to change all vehicles owned or leased by private firms to pollution-free cars. The goal is to contribute to the reduction of greenhouse gases and air pollutants by increasing the proportion of eco-friendly vehicles such as electric cars.
