Slide 5: What net zero means
What net zero means “To get there, we need to achieve a deep and profound elimination of emissions across the global economy. Where emissions cannot be eliminated, we must neutralize the impact by withdrawing an appropriate amount of carbon from the atmosphere” sciencebasedtargets.org ELIMINATE NEUT

Slide 12: Start with electricity supply
Start with electricity supply ✓ RethinkX© model applied to microgrids, validated by Gold Fields own studies ✓ 3x – 5x solar & wind generating capacity compared to mine load ✓ 35 – 90 hours of energy storage ✓ Agnew example (A$113m for 54% REF) needs a further A$500m invested to increase to 100% REF
