In road paving, solar pavement is being developed worldwide against the backdrop of the Paris Agreement, which set a long-term goal of mitigating climate change by 2050 and beyond, SDGs, carbon neutrality and other initiatives. In addition to providing traveling space, pavement, which covers a certain size of surface area in cities and regions, has the potential to generate new values to create renewable energy. We are developing solar pavement with the aim of developing road paving technology that contributes to carbon neutrality, and are conducting demonstration testing, primarily, test paving, in places with vehicle traffic.
