  • Cut 77% from Your Carbon Footprint

    Over the past two years, I cut 77% from the average Australian household footprint. I ran one-week experiments to cut carbon and used carbon accounting to see what worked. I tried simple lifestyle changes anyone can make.

    The chart, slideshow and video below give an overview. Each one-week experiment is covered in a Post. Data and spreadsheets appear in the Notes. I'm giving workshops and writing articles and a book to show how to cut carbon.

    1. Renewable household electricity

    Meet all your household electricity needs with 100% renewable power. Ask your state government to switch the grid to 100% renewable electricity (like the ACT has). Until they do this, and if you're in a position to do so, think about installing rooftop solar or buying into a community or GreenPower scheme.

    2. Electric car

    If you're in a position to buy a new or secondhand car, try an EV. If you swap a petrol or diesel car for an electric vehicle you'll cut over a tonne from your footprint (and no more petrol bills). Run it on 100% renewable electricity to save even more carbon.

    3. Fly Less

    Fly one-third the distance you currently fly. Teleconference, take a bus, train or car and enjoy local holidays. Avoid Business and First Class which are more carbon-intense.

    4. Get Off Gas

    Natural gas is a fossil fuel that used to be seen as green, but it's a poor choice now that we have efficient electric appliances and renewable electricity. Gas fracking also leaks unknown amounts of methane into the atmosphere. Whenever a gas appliance breaks, replace it with electric. If you can swap all your gas appliances for electric, you'll save big on carbon (and likely on power bills too).

    5. Vegan

    A vegan diet with no meat, fish, dairy or eggs is very low carbon. It's increasingly popular and there are restaurants, cookbooks and delicious products to help. But if veganism is not for you, don't panic! Try the Supermarket Swap instead.

    6. Mass Transport

    Try reducing your driving using public transport for work commutes and regular trips. Trip-chain and plan your meetings and errands, or maybe work from home a day a week. However you do it, if you limit your driving to 32 kilometres per person per week you'll save nearly a tonne of carbon.

    7. Supermarket Food Swap

    Eat more plant foods. Limit red meat to once a month. Eat white meat, fish and dairy in moderation. Swap in tofu, hommus, lentils, beans, coconut, nuts, avocado & non-dairy milk. This diet cuts carbon compared to the average and it still has over 1 kilogram of meat and 1 kilogram of dairy each week.

    8. Carbon Pawprint

    Feed dogs a 'complete and balanced' kibble that lists grains as the first ingredient and has no beef or lamb. Choose treats that are vegan, roo or white meat. These steps will slash your carbon pawprint by over half a tonne.

    9. Lights, Appliances, Insulation

    Household efficiency saves electricity, carbon and cash. Measure the power used by fridges, heaters and computers with an appliance meter. Run fewer big appliances (one fridge not two) and run them for fewer hours (turn off your desktop when you're not working). If you can, upgrade your fridge or change its seal. Use LED light bulbs. Draught-proof and insulate your home (see Week 9 and Week 28).

    10. Active Transport

    If you're able to use active transport, try cutting your car kilometres by 30% this way. You can do this by riding to work two or three days each week, or walking some errands and school drop-off.

    11. Buy Less, buy Better, Don't Fly It In

    Cut your purchases of furniture, toys and other stuff in half. Then buy half of that remaining stuff secondhand or made from recycled material. Don't buy if it flies. Ask your online retailer if they ship by sea and road freight and if not, say no. Never pick Express Shipping.

    12. Vegetarian

    If you don't want to go vegan or try the Supermarket Swap, you could try vegetarian? I sampled a creamy and delicious diet that slashed carbon from the average high-meat Aussie fare. But remember, many dairy foods are as high-carbon as chicken and some seafoods are even higher. This cuts carbon but you'll need to do your research.

    13. Drink Less

    Cut carbon by cutting your drinks in half. Beer, wine, spirits and soft drink all have similar carbon indexes, so pick your vice but reduce the overall amount. If you must drink sweets, mix your own from cordial. Drink tap water, not bottled water.

    14. 5:2 Fast

    The 5:2 Fast is a weight-loss diet for healthy adults that restricts calories two days each week. This will cut carbon, but only if you keep your normal diet the same and eat plant-based fasting foods with a little chicken, fish or egg. A 'fast'of egg and steak generates more carbon than a day of regular eating! Use with caution.

    15. Hot Water

    It takes energy and carbon to heat your water so cut it down. Stick to 4 minute showers (shorter for frequent washers). Install low-flow showerheads. Take fewer baths and don't fill the tub right up for kids. Wash laundry in cold water. Set your water heater to 50°C.

     

    Saves 343 kilograms CO2e per person per year AND saves water.

    16. Recycle paper, Food & Garden Waste

    Paper, food and garden waste all generate methane if sent to landfill. Keep them out by reducing your paper use and separating it all out for council recycling. Put food and garden waste in the designated council bin if you have one, or in your own compost (see Week 3 and Week 4).

    17. No Fast Fashion

    Australians are the world's second-largest consumers of textiles. Clothing generates a lot of carbon. Buy 75% less new clothes. Do this by buying less overall or shopping for secondhand clothes or clothes made from recycled fibres. Pick items that last. Borrow, swap or hire for one-off pieces.

    18. heat Pump heater & Air Con

    Heat pumps are very efficient. A reverse-cycle heat pump heater & air conditioner uses less energy and less carbon than traditional heaters and air con. It also helps you adapt to climate change heat waves and bushfire smoke. You'll save even more with a heat-pump hot water system too.

    19. Turn Down the heat

    Set your winter thermostat three degrees lower than usual and put on a jumper. You'll save carbon and money and you won't notice the difference after a week.

    20. Waste Less Food

    It takes a lot of water, energy and carbon to produce our food but around one-third of it is wasted. Waste less. Buy, cook & order less. Let kids serve themselves. Don't overcater and serve plants, some white meat and no red meat at functions. Buy seconds, eat leftovers & raid the pantry & fridge before restocking. Ask your cafe and supermarket to waste less too.

     

    Saves 100 kilograms CO2e per person per week.
