This document explores essential policies for a sustainable future, focusing on zero emission energy sources and effective climate change strategies. It compares the total electricity costs of various energy sources, highlighting renewables such as wind, hydro, and geothermal in the context of their lifecycle costs. The need for good policy in carbon pricing, taxes, and trading is emphasized, alongside the economic implications of native forest management. Insights are drawn from the Stern Review on the economics of climate change. For more information, visit www.ZeroEmissionNetwork.org.au.
