President Lee Jae-myung signed a decree requiring mid-to-large public parking lots with 80+ spaces to install 100-kilowatt solar power systems. The Mandatory Parking Lot Solar Law, effective March 28, 2026, amends existing renewable energy regulations to accelerate adoption of solar infrastructure. Workers are already installing panels at the National Assembly grounds in Yeouido, Seoul, as part of the initial rollout.

This policy targets public infrastructure to reduce reliance on fossil fuels and align with South Korea's carbon neutrality goals. The law applies to parking facilities nationwide, prioritizing larger lots where solar installations can generate maximum energy output. Officials emphasize that the mandate will create a template for urban sustainability, encouraging private sectors to follow suit.

The amendment builds on South Korea's 2023 renewable energy expansion plan, which increased solar capacity targets by 20%. By integrating solar systems into everyday infrastructure, the government aims to cut 1.2 million tons of CO2 emissions annually by 2030. Critics argue the timeline is aggressive, but supporters highlight the precedent it sets for mandatory green tech integration.

The March 28 implementation date gives developers and municipalities six months to comply. Non-compliant lots face fines, though enforcement details remain unclear. The policy’s success hinges on balancing energy demands with logistical challenges, such as permitting and grid integration. As one official noted, "This is just the beginning of a broader shift toward embedded renewable solutions."
