Promising green tech startups tackling environmental crisis in 2022

promising greentech startups of 2022

Expectations for greentech are rising as governments, investors, businesses, and consumers put increasing emphasis on environmental sustainability. Companies across industries are looking for ways to decrease their carbon footprint, water use, and environmental impacts. This is where green technologies are helping organisations meet more aggressive environmental and sustainability goals.

Reportedly, there is a surge in early-stage investment in greentech companies and technologies. In recent years, investors with over $60 trillion in assets under management have committed to invest in companies driving climate change. This includes big players such as Google, Meta and Microsoft carbon-free energy consumption targets continue to gain momentum.

As it is World Environmental Day on June 5, it is time to spread awareness. We have curated a list of greentech startups that are solving environmental problems with their sustainable solutions.
