Who am I?

This substack is written by Michael Mazengarb - I have spent more than 15 years studying and working on climate and energy policy.

I have worked for federal and state governments on climate and clean energy programs, not for profits, and recently spent three years as a journalist with RenewEconomy.

I completed a Science degree at the Australian National University, with majors in physics, and climate change science and policy. I also completed a Juris Doctor at the University of Technology Sydney, with a strong focus on environmental and climate law.
