Companies in Climate Tech The number of emerging technology companies tackling the climate crisis has increased nearly 4x, by over 35,000 rms since 2010 to reach 44,595 in 2022 This explosion of firms throughout the 2010s reflects the exponential growth of climate tech, and reinforces hope that the key climate technologies are increasingly being funded to support the planet and the world tackle climate change. However, with the economic downturn negatively affecting the stock market and threatening investments to slow down, it is imperative that the private and public sector ensure that climate tech is prioritised and protected from any risk of financial decline.
