Best Environment Tech Companies in South Korea
The 162 best Environment Tech companies in South Korea in 2026, ranked by funding and momentum. Funding, investors, founders, valuation, tech stack and live signals. Top: LDC.
South Korea's Environment Tech field is more crowded than it looks from the outside — and if you're trying to map where the real capital sits, this directory ranks 162 companies by disclosed equity funding and recent funding momentum. Total disclosed funding across the sector clocks in at $166M, with Ldc leading at $42M and Poen close behind at $34M. No unicorns yet, but the funding distribution tells its own story: most companies are early and lean, which means the consolidation window is still wide open.
The global market these companies are chasing is substantial. According to MarketsandMarkets, the environment tech market sits at roughly $552.1B and is forecast to reach $690.3B by 2026, a CAGR of about 4.6%, driven by stricter government regulations and rising pressure on carbon footprints. I'd note that South Korea's regulatory posture on emissions is accelerating that pressure locally. Hot themes this quarter include EV battery technology and next-generation EV platforms, and median app install growth across environmental and renewables apps is running around 20% YoY, which signals real end-user pull. Active backers like Mirae Science and Technology Holdings, Sopoong, and EcoPro Partners are the names worth watching as deal flow picks up.
