Do sustainability grants only cover renewable energy?â–¼
No. While energy projects are a major category, green grants also cover circular economy initiatives, waste reduction, sustainable packaging, eco-design, water management, biodiversity, and carbon-neutral manufacturing processes.
Can small businesses apply for green grants?â–¼
Absolutely. Many sustainability programs are specifically designed for SMEs. In fact, smaller companies often receive higher co-financing rates — VLAIO's ecology premium offers up to 55% for small enterprises versus 35% for large companies.
Do I need to prove environmental impact?â–¼
Yes, most programs require measurable environmental targets. This typically means estimating COâ‚‚ reduction, energy savings in kWh, waste reduction percentages, or water consumption improvements. An energy audit can help quantify these.
Can I combine sustainability grants with other subsidies?â–¼
In most cases, yes — but total public funding cannot exceed the maximum allowed aid intensity (usually 40–70% depending on company size and region). Many companies combine regional green grants with federal tax incentives.
