One billion trees will be planted across Australia over the next 30 years, as part of a new forestry deal intended to assist the country in reaching its Paris Agreement climate target.

The deal will remove 18 million tonnes of greenhouse gas per year, offsetting the current production of 500 million tonnes per year.

Environmentalists say the importance of coal to the Australian economy is the country’s main obstacle to hitting its carbon emissions target and efforts must be intensified to lower emissions by 2030.
