about us

Environmental Accounting means accounting for the irreplaceable value of the living earth, air, water, and energy which make up our wonderful world, and upon which all other value is established.

Pleiades Australia founder, Samuel Nelson, is a pioneer in the rapidly developing field of environmental accounting, with over 30 years experience working with government, corporate, and non-profit clients.  Samuel is a co-founder of the Australian Institute of Environmental Accounting and lectures on the subject for the Curtin University Sustainable Engineering Group.  

Pleiades is bringing together a team of like-minded specialist  professionals to assist organisations with accounting for their environmental assets and liabilities.  Join us to promote positive stories that will stand the test of time.
