What is Green Technology?
Green Technology startups first cropped up in 2005 when VC investment was measured in the millions. Fast forward over a decade, increasing awareness about the impacts of climate change and the depletion of natural resources has attracted enormous amounts of investment capital, with many entrepreneurs and private investors believing a ‘Green Revolution’ is at hand.
So far in 2025, green technology is looking to have another record breaking year, despite the political climate being less favorable than in recent years. The green technology and sustainability market is predicted to experience substantial growth by 2030, reaching $73.9 billion.
Despite wariness for investors to enter the green tech space, capital and talent continues to flow into GreenTech as new startups are pulled to the forefront of their sector through exciting innovation and industry-disrupting business models.
