Insights From Australia’s Latest National Greenhouse Gas Inventory Update

Introduction

  • Australia is committed to reaching net zero emissions by 2050, and has now set a new intermediate target: a 62–70% reduction in greenhouse gas emissions below 2005 levels by 2035.
  • The recently released Net Zero Plan and supporting sector plans outline how Australia will achieve this while building a stronger economy powered by clean energy, creating new jobs, and delivering benefits for households and businesses.
  • Using the latest national greenhouse gas inventory data from DCCEEW, this presentation tells the story of Australia’s emissions path from national trends, to sectoral shifts, gas composition, energy system transformation and growing role of renewable energy in Australia’s future.
  • By understanding where emissions come from, how they’re changing, and what solutions are available, we can assess not just what’s been done but what still needs to happen to stay on track to net zero.

National Emissions Overview

Emissions have fallen steadily since 2005, but progress has plateaued in recent years. Stronger action is needed to meet the 2035 target such as expanding clean electricity, adopting cleaner fuels, and advancing new technologies.

Sectoral Emissions Breakdown

Emissions have fallen from electricity generation, but transport, stationary energy, and industrial processes continue to rise, showing that sectors are decarbonising evenly. Stronger policies and faster electrification are needed to close the gap.

Australia’s Emissions Profile

Carbon dioxide (CO2) still makes up most of Australia’s greenhouse gas emissions, but slower progress in cutting methane (CH4) and nitrous oxide (N20) shows difficulty in tackling pollution from farms, waste, and industrial processes.

Australia’s Changing Energy Mix

Fossil fuels continue to dominate Australia’s energy mix, with coal, gas, and oil accounting for the majority of consumption. However, renewables have grown steadily, now contributing nearly 30% of electricity generation.

Australia’s Shift to Clean Power

Renewable generation from wind and solar has surged across the National Electricity Market, replacing coal as the dominant source of change in generation, highlighting the steady shift toward cleaner, zero-emission energy sources.

Tracking Transport Emissions

As seen earlier, transport is the biggest contributor to national emissions. Reducing this will require greater investment in public transport, faster electrification and a transition to cleaner fuels like hydrogen, biofuels, and renewable power.

The Road to Net Zero

In conclusion, energy use per person in Australia has been declining for over a decade and is projected to continue falling as efficiency improves, electrification expands, and renewables replace fossil fuels, showing that the path to net zero is not just possible, but already underway.
