Best Environment Companies in Sweden
The 368 best Environment companies in Sweden in 2026, ranked by funding and momentum. Funding, investors, founders, valuation, tech stack and live signals. Top: Elvy Energy.
Sweden's Environment sector is stacking up fast, and this page ranks the 368 companies we track here by disclosed equity funding and recent momentum. Total disclosed funding sits at $868M, with Elvy Energy alone accounting for $593M of that, which tells you something about how concentrated the capital picture is right now.
The global environment market hit roughly $68.8B in 2024 and is forecast to reach around $73.5B by 2025, a 5.3% CAGR driven by tightening climate regulations and infrastructure buildout. So where's the rest of Sweden's funding going? Liquid Wind has pulled in $83M, Ekolution $16M, and Novatron Fusion $9M, with Almi Invest and the EIC Fund among the most active backers keeping the mid-tier moving. Median app install growth across environmental and renewables platforms is running at roughly +20% year-on-year across 161 tracked apps, which signals real end-user engagement, not just boardroom conviction. Regulatory scrutiny is sharpening too, and expert panels clearing expansion projects despite pending cases show how compliance pressure cuts both ways globally. You want the companies built to absorb that pressure. That's what this list is for.
