Option 1 -> Hydrogen is not a target emission for Net Zero goals; it's actually considered a potential clean energy carrier.
Option 2 -> Net Zero refers to balancing greenhouse gas emissions by reducing them drastically and offsetting any remaining emissions through removal or carbon capture.
Option 3 -> E-waste reduction is an important environmental goal but is not related to the Net Zero concept, which focuses on atmospheric emissions.
Option 4 -> Microplastic pollution is a separate environmental challenge and not the focus of Net Zero targets.
Hence, Option 2: Cutting Green House Gas (GHG) emissions to zero -> Net Zero means achieving a balance between GHG emissions produced and removed from the atmosphere, typically by 2050 as per international climate commitments, through emission reductions and carbon removal strategies -> correct
