Net zero means balancing greenhouse gas emissions produced with those removed from the atmosphere, not eliminating all emissions. In Australia, the Climate Change Bill aims for a 43% reduction in emissions from 2005 levels by 2030 and net zero by 2050.
However, there are differing opinions about what net zero means for society. Under the Paris Agreement, Australia pledges to limit global temperature increases to well below 2°C, with hopes of staying below 1.5°C. Current warming in Australia is already 1.5°C, leading to more extreme weather events, causing concern among professionals like Dr. Kim Loo.
