Best Environment Tech Companies in Belgium
The 180 best Environment Tech companies in Belgium in 2026, ranked by funding and momentum. Funding, investors, founders, valuation, tech stack and live signals. Top: Virya Energy.
Belgium's Environment Tech sector earns its own ranking here: 180 companies tracked, $366M in total disclosed funding, and a global market that MarketsandMarkets puts at $552.1B in 2021, forecast to reach $690.3B by 2026 at a 4.6% CAGR. Virya Energy leads the Belgian field with $100M raised, a figure that dwarfs the next tier. Gorilla ($31M) and e-peas ($32M) are the only others cracking eight figures. So the funding here is concentrated, not distributed. No unicorns yet, but the capital is real and the momentum is building.
What's driving it? Stringent government regulations on carbon emissions, rising awareness around footprint accountability, and genuine demand for renewable energy infrastructure are all pushing capital into this space. I'd note that digital delivery is accelerating too: median install growth across environmental and renewables apps runs at roughly +20% year-on-year across 161 tracked apps, which tells you adoption isn't just institutional. Battery technology and EV powertrain advancements are emerging as the sector's hottest technical themes. Active backers include Europa, EIC Fund, and imec.istart, which means you're looking at a mix of pan-European and Belgium-native capital stacking behind these companies. The funding may feel modest against global peers like Veolia or AECOM, but the trajectory is pointed firmly upward.
