Approx. 250 trees
will be planted including a donation from ZEN for The Forktree Project from each vote. These trees will absorb 41,000+ kgs of carbon dioxide (CO2)
1.5°C commitment
According to the voters, Australia should show leadership by ensuring our targets are in line with a 1.5°C emissions trajectory


Australia’s Sustainability Leaders have their say. Download our White Paper to see the voting process and results. Together, we are leading communities into the zero-carbon world.
ZEN Energy invited attendees at the Sustainability Leaders Summit in Australia in March 2023 to cast their votes across a range of six actions that Australia could take to improve our chances of meeting our carbon emissions reduction targets.

Issues voted on:

  • Increase the Renewable Energy Target (RET) to 82% renewables by 2030
  • It’s time to develop a domestic manufacturing capacity for solar, wind, and batteries
  • Australia should commit to a 1.5°C science-based emissions trajectory
  • We need a Carbon Border Adjustment Mechanism
  • We must support, at all levels, the development of our green hydrogen industry
  • Now is the time to impose a light vehicle emission standard

For every vote that was cast, ZEN Energy committed a tree to be planted by The Forktree Project in South Australia. The Forktree Project is a registered charity whose goal is to return a degraded 133 acre former pastoral property in South Australia’s Fleurieu Peninsula back to nature.

ZEN has committed to plant 250 trees as a result of the Sustainability Leaders Summit.

We will keep working consistently on its purpose of leading communities into the zero-carbon world.

My argument is that voluntary action has been remarkably successful recently at kick-starting positive change, but to finish the job we need our government to mandate further action…There’s a simple solution here, which is to embrace mandatory targets. Don’t shut down the market for renewable certificates and ramp up the Renewable Energy Target to 82% by 2030. The business case then stacks up, technology and capital get to work, and we get to 43% by 2030, or thereabouts.
