A Balancing Act
In the context of COP30, “net zero” means balancing the amount of greenhouse gases (GHGs) emitted into the atmosphere with the amount removed. It is the state where human-caused emissions are reduced as much as possible, and any remaining emissions are offset by removing an equivalent amount from the atmosphere.
This balance is crucial for limiting global warming, with the ultimate goal of achieving it by around 2050 to align with the Paris Agreement.
Achieving balance: Net zero is reached when the total amount of GHGs released equals the amount taken out.
Reducing emissions: The first and most important step is to drastically reduce emissions through practices like improving energy efficiency and switching to renewable energy sources.
Removing residual emissions: The remaining, hard-to-eliminate emissions can be offset by methods that remove carbon dioxide from the atmosphere, such as through forests or other carbon removal technologies.
Global goal: Net zero is the internationally agreed-upon goal for mitigating climate change, and discussions at COP30 will focus on accelerating progress towards this target.
