Huggins joined others who are calling for more ambitious emissions reduction targets well ahead of the summit in November.
The letter reads: “Can I urge that you include an Australian announcement not only to match that of the many nations already committing to net zero emissions by 2050, but also make vivid our commitment to real zero emissions asap?”
The term ‘real zero’ reflects scientists’ recent critiques that ‘net zero,’ where ongoing emissions are roughly equal to carbon sequestered, won’t be enough to avoid further climate destabilisation.
Huggins challenged Morrison to become an inspirational leader.
“In humankind's history, what does it take for us to make powerful and right decisions that bring greater safety and well-being?” Huggins asked in the letter. “Always the answer to this question includes, doesn’t it, inspirational leaders?”
