• Climate change is the most pressing crisis for humanity.
• Startup founders and investors want to help find solutions.

Climate change is the most pressing crisis humanity is dealing with right now, and startup founders and investors are racing to build and fund solutions.

The importance of impact investing, plus friendlier legislation, has fueled the rush to climate tech both in the US and Europe. Celebrities and established venture capitalists are "greening up" their portfolios, pouring billions into a sector once regarded as niche.

Leonardo DiCaprio-backed fund Regeneration VC, for example, has handed checks to founders building everything from carbon utilization to rental companies.

That meant, as capital dried up in the wider market, climate and sustainability-focused companies continued to raise throughout last year. Venture capitalists also raised funds from limited partners to focus on investing on climate tech.

Globally, climate and clean tech startups raised $54 billion in 2022, according to PitchBook. It is a near $13 billion-drop from the record levels raised in 2021, a year flush with cash and largely considered an outlier, but almost double 2020's $28 billion. Clean tech refers to startups trying to reduce human impact on the environment, while climate tech covers those on mitigation, adaptation, and decarbonization.

The sector may not remain immune to the broader slowdown in funding, with early data showing investment activity tailing off in the first quarter of 2023 to a near three-year low.
