The total energy output from solar panels reached 162MWh by 2021. In October, 2021, the Busan logistics center of SK Rent-a-car installed additional 62kWp solar panels to meet its own energy demand. The Vilicar branch in Jeju installed 60kWp solar power panels in January, 2022 to further increase its renewable energy footprint.

Alternative Energy (Fuel Cells)

SK Rent-a-car has developed the EV Smart Link to gather EV fleet operation data to objectively monitor and measure how EVs actually contribute to reduce greenhouse gas emissions. To have the contribution of its EV fleet to greenhouse gas emissions reduction recognized, SK Rent-a-car applied for the Greenhouse Gas Emission Offset Program run by the Ministry of Land, Infrastructure and Transport (MOLIT) in October, 2020 in partnership with SK telecom and mounted EV Smart Links on over 60 EVs run by its Vilicar branch in Jeju Island. The EV Smart Links captured reliable data on greenhouse gas emissions and charging/discharging rates from raw EV fleet operation data and provided inputs for predicting reduction of greenhouse gas emissions by about 150 tons on annual average versus internal combustion engine vehicles of comparable specifications, a methodology which was finally endorsed by the Emission Certification Committee of the MOLIT in January, 2022. In 2022, SK Rent-a-car also signed a memorandum of understanding on the external program of greenhouse gas emissions offset scheme with SK telecom and ReserveCarbon. The MoU will allow parties to the agreement to jointly launch the external program to estimate and certify greenhouse gas emissions reduction performance of all EVs including the EV fleet to be purchased by SK Rent-a-car way forward for approval by 2023. SK Rent-a-car will deploy EVs eligible for the program and provide emission monitoring device and solution, offering the practical benefits of greenhouse gas emissions reduction which include carbon credits returned to customers using SK Rent-a-car EVs. As a leader of the eco-friendly mobility market, SK Rent-a-car will forge ahead with its efforts to empower EV business to create social value.
