Cleantech stocks continue to outperform the wider market, notwithstanding a go-slow on climate and energy policy from the federal government.

The Deloitte Australia Clean Tech Index, an index of 93 ASX-listed cleantech companies, rose 7.8 per cent in the September quarter, compared to a 1.1 per cent rise in the ASX 200.

The Australian Cleantech 20 rose 6.9 per cent in the quarter.

The biggest sector contributors were water and renewable energy.

Most positive contributor award

The stock with the largest positive contribution to the index was market darling Phoslock, which sells large-scale water cleaning technology that permanently binds excess phosphorus in water.

It jumped into investors’ consciousness in early 2018 when it announced a maiden profit on the back of work in China, where it has been since 2005 and continues to make its fortune cleaning vast tracts of polluted waterways.

Phoslock shares rose 49 per cent in the quarter.

The company is currently working on four large projects around China with potential revenue ranging from $20m to $200m, and it secured the exclusive global licence to manufacture, sell and distribute a new product which, after removing phosphorus from polluted water, can be reused.

It expects the new product will be available by mid-2020.
