Climate & Emissions: South Korea’s greenhouse gas emissions fell 0.9% in 2025 to a provisional 685.7 million tons, with drops in industry and transport offset by increases in electricity, buildings and refrigerants—while the government pushes toward a 2035 target of at least 50% cuts from 2018. Solar Energy R&D: Researchers report a simple molecular tweak in perovskite solar cells, pushing certified efficiency above 25.6% and improving long-term stability—another step toward more practical high-performance panels. Clean Tech & Materials: KAIST-backed work uses engineered E. coli to turn glucose into biodegradable hot-melt glue polymers, aiming to reduce petroleum-based adhesive waste. Urban Heat & Cooling: Seoul used a daylighted buried stream to cool a 10km concrete highway corridor, transforming asphalt into a cooler public park—an example of nature-based climate adaptation. Robotics for Tough Environments: A Seoul startup, MilliTrack, is rolling out AMR+ localization using millimeter-wave signals to help robots navigate where cameras and LiDAR struggle (dust, fog, repetitive shelves). Zero-Waste in Practice: Incheon’s Sojoonghan Modeungeot runs a low-waste daily model—ugly produce, no disposables, and even drinking glasses made from cut beer bottles—plus hundreds of environmental classes. Air & ESG Tech Showcase: SK Telecom brings AI-based “DO THE GOOD AI” sustainability cases to Seoul’s Social Value Festa, including anti-voice-phishing and AI care services. Wildlife Rescue: Five moon bears rescued from tiny cages in South Korea arrive at a new home in Suffolk after a long journey.
