There is no one-size-fits-all answer to this question, as the number of climate tech startups varies depending on the definition of "climate tech." However, according to one estimate, there are currently more than 1,000 climate tech startups around the world.
Climate tech is a broad category that can encompass everything from renewable energy to electric vehicles to energy efficiency. So, the number of climate tech startups will depend on how narrowly or broadly you define the term.
That said, there are a few reasons why there has been a boom in climate tech startups in recent years.
First, there is an increasing awareness of the need to address climate change. This has led to more people and organizations wanting to invest in climate-friendly solutions.
Second, the cost of clean technologies has been falling, making them more financially viable.
Third, there is a growing pool of talent in the climate tech space. This includes engineers, scientists, and entrepreneurs who are developing new technologies and bringing them to market.
All of these factors have contributed to a boom in climate tech startups. And as the world continues to grapple with the challenges of climate change, it's likely that this trend will continue.
