6 Belgium-Based GreenTech Startups on a Feat for Climate Impact

Belgium has some of Europe’s most prominent financial and political institutions and is a hub of multiculturalism and variety. The small country has three national languages, making it a multilingual asset for multinational entrepreneurs. With French, Dutch, German, and a strong level of English, Belgium-based GreenTech startups are working at a global level despite hindrances “imposed by the inter-regional coordination, a lack of eco-innovation and circular economy related skills in SMEs, a limited control over product design for most products entering the market and the very low environmental taxation.” Source
