OPINION: Money can grow on trees

By Brian Page

I NOTE calls from the forestry industry to plant a billion new trees and the issue of water rights, plus opportunities for our most important industry.

Carbon credits is a core issue and one recent and accurate estimate is that an average sized tree over a 50 year life produces oxygen worth about $30,000 in today’s money or about $600 per tree each year.

But forest trees being much larger with typical tree life 25 years produce much more oxygen, perhaps double and a conservative $900 a tree per annum equates to an annual carbon value (or oxygen value) for a billion trees of at least $900b per annum.

Trees are by far the biggest
