Which scope of emissions is hardest to reduce?

Scope 3 (value chain emissions) represents ~70% of most companies' footprints but is hardest to control. It requires supplier engagement, product design changes, and customer behaviour change. Scope 1 and 2 are directly controllable and typically addressed first.

What is the difference between net zero and carbon neutral?

Carbon neutral allows offsetting residual emissions. Net zero (IPCC standard) requires deep emissions reductions (90%+) with only minimal high-quality offsets for hard-to-abate residuals. Science-Based Targets initiative (SBTi) certifies net zero pathways aligned with 1.5°C.
