Youths from around the world are forging ahead with an online climate summit in the hopes of stamping strong targets in law.
This year's United Nations Climate Change Conference, known as COP26, was due to be held in Glasgow this month but was postponed until next year because of the coronavirus pandemic.
It's prompted more than 350 youth delegates from over 140 countries to take part in a virtual 'mock COP26'.
COP26 President and UK politician Alok Sharma will join the teenagers on Friday to applaud their efforts.
"This event will further demonstrate the appetite that exists across the world for governments and organisations to take ambitious climate action," he said.
With help from pro bono lawyers, the summit's final statement will be developed into a formal treaty and handed to governments to consider adopting into law.
Australia's five-person delegation includes Adelaide year 10 student Tom Webster, who is raising awareness of Indigenous perspectives on bushfire prevention methods, the Adani coal mine and rising sea levels in the Torres Strait.
Once the treaty is complete the Australian team will hand it to environment and energy ministers across all levels of government.
The 15-year-old told AAP he hopes for "sensible and achievable climate solutions that will ensure a safe future for all and keep us below two degrees warming before the end of the century".
"As a young person, climate policies and environmental policies will be one of the crucial things that I will be looking at when I decide who to vote for, once I turn 18."
Australia's statement to the event will focus on last summer's bushfire season and the climate impacts on coral reefs.
The delegates will also promote the transition to renewable energy to achieve net zero emissions by 2050, drive investment and create jobs for fossil fuel workers and their communities.
Next year's COP26 event looks at how nations meet the Paris Agreement goals, with countries asked to beef up their climate ambitions and emissions reduction targets.
Australia has not put a time goal on achieving net zero emissions, and is instead taking a technology investment roadmap to the climate conference.
