10 New York Greentechs to Watch in 2023_hero-3

As a class of exciting greentech startups is becoming a crucial part of the New York's ecosystem, the tech hub is once again at the forefront of a major conversation: the need to cut down on carbon use and reduce greenhouse gas emissions.

There are currently over 500 greentech companies in the Big Apple. More recent initiatives, such as the $250 million Community Decarbonization Fund oriented at financing clean energy projects, continue to drive further growth in this industry segment. Let’s take a look at ten of the most prominent green startups that contribute to the improvement of our environment with tech.
