10 ASX Cleantech Stocks

Clean technology covers a number of industry sectors, such as low-emission technologies, renewable energy, water and wastewater technologies as well as waste and resource efficiencies.

In the first half of 2021, the global cleantech space performed well, almost above expectations.

“There is a clear shift in the industry that is prioritising investments into the space,” Yuan-sheng Yu of Lux Research told the Investing News Network. “Whether that is purely through the installation of renewable energy capacity or in early stage technologies.”

Australia’s cleantech arena is also performing with strength, according to the Deloitte Australia CleanTech Index, which offers a quarterly review of cleantech stocks listed on the ASX.

“The companies included in the Index range across renewable energy, energy efficiency, resource efficiency, energy storage, battery minerals and water treatment,” states Renew Economy. “These are the industries that are redefining how cities work and how our communities live, so it is likely we will see them continue to play a critical role in our economy’s post-Covid recovery.”

With the positive outlook for cleantech in mind, here’s a look at 10 ASX cleantech stocks that are tracked by the Deloitte Australia CleanTech Index. Companies are listed in order of largest to smallest by market cap, and all numbers and figures were current as of July 30, 2021.
