Final month’s dire report by the Intergovernmental Panel on Local weather Change might have left you feeling overwhelmed, or uncertain what to do subsequent. We regularly hear about methods on a regular basis individuals can sort out local weather change, however which acts will make the largest distinction?
The educational literature tells us three spheres of our lives contribute most to local weather change: residence power use, transport, and meals consumption. Collectively, these actions comprise about 85% of a family’s carbon footprint.
As one study confirmed, by adopting available practices, households in developed international locations can lower their carbon footprint by 25% with little or no discount in well-being.
Clearly, nationwide governments should set, and meet, bold emissions-reduction targets. However 72% of global greenhouse gas emissions are associated to family consumption. So small modifications on the family degree actually could make a world of distinction. Right here’s a information to get you on the fitting path.
Utilizing power within the residence extra effectively is an efficient solution to scale back your influence on the local weather. Signing as much as so-called “demand response” applications is a comparatively new method to do that.
Demand response includes making modifications to power use to scale back stress on the electrical energy grid throughout occasions of excessive demand. In Australia, this usually entails electrical energy corporations providing monetary incentives to households so that they use much less power at peak occasions.
For instance in Queensland, the state-owned firm Energex offers up to A$400 to those that set up a “PeakSmart” air conditioner. When the electrical energy system is beneath stress, the electrical energy community will remotely change the air-conditioner right into a decrease efficiency mode.
Vitality retailers have additionally been trialling demand response applications in different states. For instance beneath AGL’s Peak Vitality Rewards program, prospects can select to obtain an SMS message prompting them to scale back their power use at peak occasions. By turning up the temperature on the air con or ready to do the laundry, individuals can earn reductions on their power payments.
Demand response results in much less electrical energy use and reduces the necessity for fossil-fuel electrical energy technology at occasions of excessive demand – and so, can lower greenhouse fuel emissions within the electrical energy sector.
When you drive a standard petrol or diesel car, attempt to scale back the period of time your engine idles. Analysis final 12 months discovered Australian motorists are prone to idle greater than 20% of the time they’re driving. If idling was eradicated from all journeys, the emissions saved would equal that of eradicating as much as 1.6 million automobiles from the street.
Whereas some idling is unavoidable akin to when stopped at visitors lights, drivers can flip their engines off whereas parked and ready of their car.
And drive easily, not aggressively. Driving with restricted acceleration and braking has been found to considerably scale back emissions.
You is likely to be pondering of constructing your subsequent automobile an electrical car. Whereas the price of electrical autos has historically been prohibitive for many individuals, the expertise is expected to reach worth parity with typical automobiles in Australia within the subsequent few years. And as of late, you possibly can even get second-hand deal.
There’s quite a lot of misinformation on the market about whether or not electrical automobiles are a sensible choice for the planet. So the place does the reality lie?
It’s true that electrical energy used to cost an electrical car’s battery is usually sourced from fossil fuels. And power continues to be required to make an electrical car – specifically, the battery.
Nonetheless, final 12 months, research found in 95% of the world, electrical autos had been much less emissions-intensive than conventional automobiles over their full life cycle – even accounting for the present emissions depth of electrical energy technology.
When you purchase an electrical car, it’s necessary to make sure potential emissions financial savings are realised. A method of doing that is by recharging throughout the center of the day when renewable electricty is most abundant. And don’t overlook, as renewable power varieties an ever-increasing share of the electrical energy combine, the local weather advantages of electrical autos change into even higher.
And naturally, don’t overlook in regards to the apparent low- or zero-emission methods to get round: strolling, biking, catching public transport and automobile pooling.
Research earlier this 12 months confirmed meals methods are chargeable for a 3rd of human-caused greenhouse fuel emissions. And recent studies show even when the world stopped burning fossil fuels instantly, emissions from the worldwide meals system may nonetheless push international temperatures over the 1.5? warming threshold.
Decreasing meat consumption is a widely known method to cut your carbon footprint. The truth is, recent research from Sweden confirmed simply how excessive emissions from meat and dairy merchandise are, in contrast with substitute merchandise. It discovered:
- lamb is 25 occasions extra polluting than tofu
- milk is 5 occasions as polluting as oat drink
- dairy-based cheese is 4 occasions as polluting as vegan cheese.

In Australia, the vary of meat options is rising rapidly. In only one instance, Sydney-based All G Meals is creating plant-based mince, sausages, rooster and bacon, in addition to “cow-free” dairy merchandise. Helped alongside by $5 million in federal authorities funding, the corporate’s first product launches this month.
One other meals that guarantees to assist lower your carbon footprint is seaweed. Australia is just simply catching on to the advantages of business seaweed manufacturing, which will be grown with few environmental prices.
Australia’s first manufacturing unit manufacturing food-grade seaweed merchandise opened in New South Wales final 12 months. It has the capability to place seaweed into pastas, and even muesli!
Cut back, reuse, encourage
Decreasing your local weather footprint isn’t just about shopping for “inexperienced” stuff: it’s additionally about avoiding consumption within the first place. So attempt to purchase much less – and for those who can’t keep away from it, try to purchase second-hand.
You by no means know, you would possibly begin a revolution. Evidence suggests individuals who observe their friends enterprise environmentally pleasant behaviour usually undertake comparable actions.
