Australia's Carbon Story — Emissions, Targets & the EV Inflection

// key_findings

1. 01.

   Electricity is the success story: renewables dropped the sector's share from 37% of national emissions (2007) to 29% today — bending the curve by ~50 Mt since peak.

2. 02.

   Transport is the structural problem. Australia's 20-million-vehicle fleet turns over at ~1.5M new vehicles per year. Even with 100% EV new-car sales today, full fleet electrification takes 13 years.

3. 03.

   Fugitive emissions (LNG) grew 4 Mt since 2015, quietly offsetting a portion of electricity's gains. The LNG expansion paradox: Australia exports low-carbon energy enablers while increasing its own methane footprint.

4. 04.

   Agriculture is the intractable sector. Livestock methane and soil nitrous oxide don't respond to electrification. Carbon sequestration via soil carbon projects is the only credible mechanism, and MRV is expensive.

5. 05.

   The 2030 target (342.9 Mt, −43% on 2005 baseline) requires cutting ~26 Mt per year from today. Current pace is ~14 Mt/year — the required acceleration is 1.9×.

6. 06.

   The EV inflection (~2026-27 projected) will bend the transport curve, but the fleet composition lag means transport emissions won't fall materially until 2029-30 — just as the target deadline hits.
