25 Practical Ways to Reduce Your Carbon Footprint in Australia

Individual actions accumulate into collective impact. Here are 25 practical, Australian-specific steps that reduce emissions and often save money at the same time.

Your carbon footprint is the total greenhouse gas emissions generated by your daily activities — driving, flying, energy use and food choices. Australia has among the world's highest per-capita emissions. But many of the most effective individual actions also save money, which makes the case for taking them straightforward.

Home Energy

• Install rooftop solar — the most impactful single action for most homeowners; payback 4–8 years at current electricity prices
• Switch to a green power tariff or GreenPower-accredited retailer if solar is not yet feasible
• Replace your gas hot water system with a heat pump hot water system — reduces water heating emissions by 60–75%
• Replace gas space heating with a reverse cycle heat pump (split system) — 3–5x more efficient than gas
• Seal drafts around doors and windows — takes an afternoon and costs $20–$100
• Add ceiling insulation if your home has none — often the highest-return home efficiency investment
• Replace all remaining halogen or incandescent bulbs with LED equivalents
• Plug televisions, gaming consoles and chargers into smart power boards — standby power can account for 5–10% of your bill
• Set your reverse cycle thermostat to 24–26°C in summer and 18–20°C in winter
• Wash clothes in cold water and line-dry where possible — clothes dryers are heavy energy users

Transport

• Switch to an EV or PHEV when next replacing your vehicle — charging at home is significantly cheaper per kilometre than petrol
• Maintain correct tyre pressure — under-inflated tyres increase fuel consumption by 3–5%
• Use public transport for commutes where available — trams, trains and buses emit far less per passenger than a private car
• Work from home where possible — even two days per week meaningfully reduces transport emissions and costs
• Combine errands into single trips to reduce cold-start fuel use
• Consider cycling or e-bikes for trips under 10 km — zero emissions and often faster in urban areas
• Offset or reduce flights — aviation is one of the highest per-journey emission sources

Food and Consumption

• Reduce red meat consumption — beef produces roughly 20–60 kg CO₂e per kg, compared to 2–3 kg for chicken or legumes
• Buy local and seasonal produce — reduces refrigerated transport emissions and supports local agriculture
• Reduce food waste — roughly one-third of all food produced globally is wasted, representing wasted land, water and emissions
• Compost organic waste — diverts food scraps from landfill where they produce methane, a potent greenhouse gas
• Buy fewer new goods and prioritise second-hand, repaired or long-lasting items
