Most of us are looking for ways to live a little more sustainably, but have you ever considered the size of your pet’s "environmental pawprint"? Between meat-heavy diets and plastic waste, our beloved companions can have a surprisingly large impact on the earth. In fact, some experts suggest a medium-sized dog can have a similar carbon footprint to a large SUV! The good news is that being a great pet parent and being eco-conscious go hand-in-hand. With a few simple swaps - like choosing locally made treats or opting for compostable waste bags - you can keep your pet happy and healthy while doing your bit for our beautiful Australian environment.

Choosing the most sustainable pet species
Of course, you might already own a cat or a dog or have your heart set on adopting one. But if you're not yet a pet parent, and are open to other species, why not consider something a little more eco-friendly?
According to sustainability author Brenda Vale, the 'most sustainable' pet is ideally small and vegetarian, while the 'least sustainable' pet is larger and carnivorous. This is primarily because it requires a lot more land, energy and resources to grow meat as opposed to grains.
What are the most sustainable pet species, and why?
1. Chickens: Not only do chickens provide eggs, meaning you don't have to buy eggs and contribute to the commerical egg industry, but they are basically just walking, flapping, compost disposal units. As omnivores, they can be fed anything from leftover veggies to meat offcuts - making good use of your household food waste! Chickens also eat all ground dwelling bugs, including funnel web spiders and ticks, which reduces your reliance on pesticides!
2. Rabbits and Guinea Pigs: These adorable creatures are tiny, naturally vegan, and have fabulous personalities. 80% of their diet should consist of grass - which grows for free almost everywhere! Just like chickens, rabbits and guinea pigs can eat your leftover fruit and veggies, which can help reduce your overall food waste.
3. Birds: Parrot species such as cockatiels, budgies, and lovebirds are small, vegan, and incredibly intelligent. While they can be fed leftover veggies and greens, they do require a balanced bird food as the base of their diet (NOT a seed diet) to keep them healthy.
4. Fish: particularly smaller vegetarian or insectivore species who don't require energy-guzzling tanks or electornic filters (like the eco-friendly Siamese Fighting Fish). Their small size and very low requirement for food makes fish a sustainable and affordable pet species!
The environmental benefits of adopting a rescue pet
If you've decided you simply can't live without a cat or a dog, it's far more sustainable to adopt a 'second hand' pet who needs a home. Animal shelters are always full of unwanted dogs and cats, and there are many benefits to adopting an adult dog or cat rather than purchasing a puppy or kitten.
The breeding of pets to keep up with our insatiable demand for 'breed specific puppies' contributes directly to pet overpopulation. This can create serious issues for the environment, including increased waste production, as well as the need for additional farming space to provide enough food to feed those extra carnivorous mouths. Adopting a rescue pet and having it desexed can help combat this problem.
Looking for a breed in particular? Why not try Pet Rescue? This Australian website collates information from rescue shelter and foster networks all over the country, and even support initiatives such as vet support and charity drives.
Why overfeeding contributes to your pet's carbon footprint
By simply feeding the amount of food your pet actually needs, rather than filling their plate up every time they bat those 'puppy dog' eyes at you, your pet's carbon footprint will decrease significantly. You'll go through less food over all, buy fewer bags of kibble each year, and consequentially help to reduce the demand on the meat industry.
Plus, not only will your pet's health benefit - remember that obesity is painful, leads to to a number of health conditions such as diabetes and arthritis, and shortens your pet's life - but you could save a lot of money in the long run, too!
Did you know: Many pet owners feed double (or more) their pet's recommended daily feeding amount. These pet owners could literally halve their food bill, and their pet's carbon footprint, by simply resisting the urge to overfeed.

How to choose an eco-friendly pet food brand
As we start to discuss how to feed your pet in an eco-friendly way, a number of questions may arise:
1. Vegan diets for pets?
It's long been established that a vegan or vegetarian pet diet is an environmentally sustainable choice - and interestingly, one study found that pet owners are more likely to be vegetarian or vegan themselves. However, a plant-based diet is simply not feasible or healthy for carnivorous cats, and certainly not ideal for high-meat-requiring dogs.
2. Home cooking vs commercial pet food?
Interestingly, home-cooked diets for pets are far less environmentally-friendly than commercial pet food diets. This is because commercial pet food uses offcuts or by-products of the meat destined for humans that may otherwise go to waste, whereas home cooked diets tend to require buying fresh meat. This contributes to the demand and production of meat overall.
3. Choose a sustainable pet food brand
A sustainable pet food brand which delivers complete and balanced nutrition is our top recommendation. Rather than trying to force your pet into a plant-based diet that doesn't align with their nutritional requirements, or attempting a home cooked diet which may be deficient in vitamins or minerals, we suggest swapping to a brand of balanced pet food which focuses on sustainable practices.
A number of brands are available these days who align with environmentally sustainable ideologies - including Open Farm, Ziwi Peak, K9 Natural, and Orijen, to name a few.
Features to look for in a sustainable pet food brand include:
- Sustainably-sourced fish. Look for a statement outlining compliance with Ocean Wise or Seafood Watch Standards.
- Land meat sourced from smaller, local farms - this may be displayed with a traceability feature on their website, as is the case with Open Farm.
- Certified humane welfare standards - while welfare restrictions are not always motivated by a sustainability angle, humane standards often benefit the environment due to the smaller animal-per-hectare requirements. Fewer animals per farm means less waste products per hectare, and fewer methane emissions overall.
- Recycled, biodegradable, or recyclable packaging

Sustainable protein sources for Australian pets
Did you know that some types of meat have a smaller carbon footptint than others? When we examine the amount of energy used and emissions generated by the entire farm-to-fork process, some meat options come out in front as clear winners.
According to one study, the types of meat which produce the least greenhouse gas emissions per kilogram in Australia include:
- Salmon*
- Chicken
- Kangaroo
- Rabbit
*It's important to note that the emission of greenhouse gas isn't the only factor to consider. For example, Salmon may rank as number 1 in terms of green house gas emissions, but it can have detrimental effects on the environment in other ways. The farming of salmon involves concentrating large populations of fish in a small area, which contributes huge amounts of nitrogen-rich waste into the ocean. This leads to the prevalence of toxic algal blooms. On the other side of the coin, catching salmon in the wild can contribute to over fishing and by-catch, disrupting the ocean's ecosystem and depleting threatened species.
Kangaroo, on the other hand, is continuously recommended as a highly sustainable meat choice. Solely wild-caught instead of farmed, kangaroo meat requires no land clearing or destruction of native habitat. Depending on the season, kangaroos generally live in abundance - to the point of even being considered a pest - and can survive on indigenous scrub so do not rely on the production of grain. Plus, compared to other specieis of red meat animals, they produce less methane gas!
Is the kangaroo meat industry cruel? The welfare of hunted kangaroos has come under fire recently, with many concerned about the stress endured during a hunt. Compared to farmed animals which are required to be slaughtered in a controlled method, the risk of wounding, but not killing, a wild animal is always a concern when hunting is involved. However, many debate whether a life spent free roaming (compared to the chronically suffering life of intensely farmed feedlot animals) outweighs a relatively short period of trauma during a 'final hunt'. As it stands, there will always be differing opinions about the welfare of wild-caught kangaroo. But the sustainability advantage is generally well-established.
Sustainable treats
There are now a wide range of sustainable protein treats available to treat your pet sustainably. Insect based protein treats from brands such Buggybix, kangaroo-based treats from brands such as Natures Cuts, and plant-based treats from brands such as Blackdog are a unique, delicious and sustainable carbon neutral treat options for your dog.
Why buying Australian made matters
Buying locally-made products is always one of the easiest ways to reduce your carbon footprint. Products made locally require fewer legs of transport, as they haven't required a ship or flight from overseas. This means that less pollution has been created to get the items to your door!

Buying in bulk
Pets require a lot of supplies - from the countless kilograms of food, cat litter, bedding, and parasite prevention - it all adds up!
Buying your pet supplies in bulk significantly saves on packaging materials and transport. Plus, it's cheaper! On a price-per-kilo scale, bulk bags will saves you a lot of money in the long run.
Read more about the value of bulk buying in our article Don't Be Fooled By Cheap Pet Food.
Switching to biodegradable and clumping cat litter
Indoor cats use a staggering amount of kitty litter. Did you know that each cat who uses a non- clumping litter goes through an average of 45 kg per year? Many crystal litters are made from synthetic plastic products, which are not biodegradable or compostable, and are definitely not eco-friendly.
Cat litter eco-friendly tips:
- Choose a biodegradable cat litter made from renewable raw materials, such as wood, corn, ground nuts, tofu, recycled paper, clay, or compost.
- Opt for a clumping litter as it will last 3-4 times longer (per kg) than a non-clumping litter. Removing clumps and waste daily, rather than replacing the entire tray, leads to less litter usage over all.
- Don't use litter liners. These are not needed if you simply use a clumping litter!
- Use a mild, eco-friendly cleaning product when cleaning your litter tray. It's good for the environment and the health of your pet!

The difference between biodegradable and compostable poo bags
Everybody knows that a good dog owner 'picks up after their dog' - in fact, in most states it is a legal requirement - and thus, poo bags have become a staple 'dog walking' accessory for most. But poo bags can contribute a lot of plastic into the environment. Most dog owners are fairly clued in to this already, and choose to buy bags marked as 'biodegradable' or 'ecofriendly.'
However, it's important to be aware that there is a big difference between doggy bags which will simply break up into small pieces of microplastics, and those which will genuinely degrade into an eco-friendly compostable substance. Many bags are marked as 'eco-friendly' despite not carrying a compostable claim. The key difference comes down to the defined term:
According to East Waste:
1. Degradable bags are made from plastic with other chemicals added (including heavy metals) that cause the plastic to break down and disintegrate over time when exposed to sunlight and heat.
2. Biodegradable bags are often still plastic bags (just like degradable bags) but have microorganisms added to break down the plastic. These still result in microplastics in the environment, and can only be placed in a regular waste bin.
3. Compostable bags are made of natural plant starch, and do not produce any toxic material. Compostable bags break down readily in a composting system through microbial activity to form compost.
Which poo bags are compostable?
For genuinely eco-friendly poo bags, we recommend Fuzzyard, Rufus and Coco or Beco brands.
Supporting eco-friendly pet accessories and recycled gear
More and more eco-friendly products for pets are emerging on the market these days. Take Aussie brand Anipal, for example. This incredible company collects plastic waste and recycles it into innovative collars, leads, and harnesses. As if this wasn't sweet enough, all of their products are decorated with colourful patterns featuring Australian wildlife!
FAQs
Raising a happy pet doesn't have to cost the earth. By making mindful choices about what we feed, how we scoop, and where we shop, we can significantly reduce our pets' environmental impact. Whether you're switching to an Australian-made kibble or recycling old plastic into a new Anipal lead, every "green" step helps ensure a healthy planet for future generations of pets and their humans to enjoy.
