Best Environment Tech Companies in Sweden
The 306 best Environment Tech companies in Sweden in 2026, ranked by funding and momentum. Funding, investors, founders, valuation, tech stack and live signals. Top: Northvolt.
Sweden's Environment Tech sector draws serious capital, and this directory ranks the 306 companies tracked here by disclosed equity funding and recent funding momentum. Total disclosed funding sits at $10.7B, a figure that one company, Northvolt, has almost singlehandedly shaped with $9.0B raised. That's not a typo.
The global environment tech market was valued at around $552.1B in 2021 and is forecast to reach $690.3B by 2026, a 4.6% CAGR driven by stringent government regulations and accelerating demand for renewable energy. So where does Sweden fit? Beyond Northvolt's outsized weight, you've got Aira at $159M, CorPower Ocean at $76M, and Exeger at $45M, each building real revenue-generating businesses in a sector where EV battery technology and next-generation EV platforms are the hottest themes right now. I'd note that median app install growth across environmental and renewables apps is running at roughly 20% year-over-year, which tells you something about where end-user demand is actually heading. Almi Invest and the Swedish Energy Agency sit among the most active backers here, alongside EIC Fund and EIT InnoEnergy, giving the ecosystem a funding infrastructure that goes well beyond early-stage bets.
