Best Environment Companies in Spain

The 412 best Environment companies in Spain in 2026, ranked by funding and momentum. Funding, investors, founders, valuation, tech stack and live signals. Top: Aqualia.

Spain's Environment sector is moving fast, and this directory cuts through the noise: 412 tracked companies, $6.5B in total disclosed funding, and one unicorn already in the mix. Aqualia leads the pack at $1.3B raised, with Gestcompost not far behind at $131M. Those two alone tell you where institutional capital is concentrating: water infrastructure and waste-to-resource, both pushed along by EU environmental regulations that aren't getting softer anytime soon. The global market sits at roughly $68.8B in 2024 and is forecast to reach $73.5B by 2025 at a 5.3% CAGR, and Spain's funded cohort is positioned squarely in that growth lane.

What I find striking is the digital signal running alongside the capital story. Across 161 environmental and renewables apps, median install growth is running at roughly +20% year-on-year, which means consumer and enterprise engagement with this sector isn't just a funding narrative. It's showing up in behavior. Investors like EIC Fund, EIT InnoEnergy, and Lanzadera are backing that thesis actively. Regulatory clearance decisions globally are also shaping how companies here structure their growth plans. So if you're evaluating partners or funding targets in this space, the rankings below are ordered by disclosed equity and recent momentum, the two signals that actually matter right now.
