President Moon Jae-in pledged to more than double the country's solar and wind energy facilities by 2025.

Marking the Second International Day of Clean Air for Blue Skies on Tuesday, Moon called for massive economic restructuring involving a shift towards an increased reliance on renewable energy sources through technological innovation.

The president pledged to support businesses in the battery and hydrogen power sectors as they face challenges in adjusting to the new global order, as the presidential office expects the government's carbon neutrality policy to offer opportunities for these firms.

Referring to the newly enacted carbon neutrality law containing a target of reducing emissions by at least 35 percent by 2030, Moon said the government will announce its reduction plan within the year.

The president also emphasized the need to reduce fine dust levels, saying the government will continue to control them through a seasonal management system.
