Table of Contents

Alrighty – in the last couple of months, we have covered a variety of topics around Australian businesses – ranging from Profitable Australian Small Business Ideas , Guide to Buying a Franchise in Australia to Famous Tech Companies in Australia.

Growing our Australian list further – today, we look at the 10 top sustainability companies in Australia ordered by their ESG grade. 

These are the companies that are investing in eco-friendly products and services.

You must be wondering – what is ESG?

Here is the answer – ESC is a parameter that measures a company’s sustainability under the U.N. Sustainable Development Goals (SDG).

The Sustainable Companies in Australia featured in this blog are listed according to their ESG grades as of 1st July 2021. 

However, the grades of these companies may change in the future due to new developments.

Again, I might update the blog in the future if we see some major change but as of now, let’s go with what the current parameters tell us.

Now before we jump to the list, here’s what is expected of a sustainable organization:

  • A healthy balance of financial growth with environmental concern and social commitments
  • A commitment to honoring environment principles in all its business practices
  • Incorporation of sustainability in organizational structure and all its business decisions

Time to dive into the list of top sustainability companies in Australia.
