We all know that trying to live more sustainably is good for the environment, but many of us are less aware that it’s good for our wallets, too.
There’s a common myth that trying to be eco-friendly costs more. But in many cases, the opposite is true – and there are plenty of ways to help the planet and improve your carbon footprint while cutting costs.
So, to inspire you, here are 17 ways to help the environment and save money.

Whether you’re looking to clear some space, make a bit of extra money, or simply let go of things you no longer need, Vintage Cash Cow makes sure your belongings find a new home and nothing goes to waste or landfill.
They accept a wide range of items including jewellery, watches, cameras, coins, medals, and more – with no cost or obligation to you.
1. Choose tap water over bottled water
Not only is bottled water considerably overpriced, but it’s also a huge waste of plastic. We’re often led to believe that bottled water is better for us – yet it can contain plastic toxins and leave a trail of waste. Most plastic is also non-recyclable and ultimately ends up in landfills or oceans, causing untold damage to marine environments.
Tap water is usually perfectly fine to drink, and you can buy a water filter or distiller if you’re concerned. Investing in a reusable water bottle is another good idea.
2. Use a reusable coffee cup
Similarly, using a reusable coffee cup will help reduce the amount of plastic and cardboard going to landfill. Many of us buy hot drinks when we’re out, so a reusable cup is a simple way to live more sustainably.
Lots of coffee shops also offer discounts to customers who bring in their own cups, so if you regularly buy hot drinks, those savings can soon add up. To find out the discounts at different coffee shops, check out this article from Ocean Finance.
3. Eat more plant-based foods
Alcohol aside, meat, fish, and dairy are often the most expensive items in a food shop, so eating more plant-based foods will likely save you money.
Plus, eating green is one of the best things you can do for the planet. According to 2023 research by Oxford University, vegan diets have 70% less environmental impact than high-meat diets. And back in 2016, studies predicted that a global switch to a mostly plant-based diet would reduce greenhouse gas emissions by two-thirds, save up to eight million lives by 2050, and avoid climate damages of $1.5 trillion.
Of course, you don’t need to switch to a fully plant-based diet to make an impact on the environment and your wallet. For example, research suggests that skipping meat for one day a week can reduce your annual carbon footprint by as much as not driving your car for a whole month. And this poll of 2,000 people found that those who reduced their meat intake saved an average of £209 per year.
The cheapest and healthiest way to eat more plant-based food is to eat more fruit and veg, and make sure you’re getting protein and other nutrients from plant sources like beans, tofu, legumes, nuts, and seeds.
To see how tasty plant-based meals can be, take a look at these 14 healthy and easy vegetarian recipes. You can also find more information in our article: What are the benefits of a whole food, plant-based diet?

4. Eat local, seasonal produce
If you’re buying more fruit and veg, it’s also helpful to eat local, seasonal produce whenever you can. All food has a carbon footprint, but food that’s flown in from abroad accounts for 11% of carbon emissions.
Eating locally not only means you’re reducing your food miles, but it’s considerably cheaper than eating out-of-season or imported produce. Seasonal produce is cheaper to harvest, while buying local produce means there’s no need for expensive transport or storage costs.
To find out more about the benefits of eating seasonally, check out our article: What fruit and vegetables are in season now?
5. Eliminate food waste
The UK throws away approximately 9.5 million tonnes of food waste each year. With animal agriculture being one of the leading causes of greenhouse gas emissions, when you consider that we’re throwing away meat, fish, dairy, and plenty of other food, the waste becomes even more harmful.
Buying food only to throw it away is also a waste of money. So, what are some of the best ways to eliminate food waste?
- Plan meals: write down a rough menu for the week and only buy what’s on your list.
- Batch cook: cooking in bulk and then freezing the leftovers saves time and money, and reduces waste.
Save veg scraps: use them to make veggie stock.
- Rescue food: apps like Olio and TooGoodToGo allow you to buy food that would otherwise have been thrown away at a fraction of the price.
6. Switch to a green energy supplier
Switching to a green energy supplier can make a huge difference. Not only does it show the industry the green energy demand, encouraging more suppliers to go green, but it can also greatly reduce your carbon footprint. Green energy is supplied by renewable energy generation, not fossil fuels.
There’s a common misconception that green energy is more expensive, but this isn’t true. In fact, it can save you hundreds of pounds each year.
Some suppliers offer a green tariff, which means that some (or all) of the energy you use is ‘matched’ by purchases of renewable energy that your supplier makes on your behalf.
You can find out more in our article: How do green energy tariffs work?
7. Be smart when washing your clothes
When washing your clothes, it’s always wise to have a full load of laundry. Not only does this save water, but it also saves energy – and will lead to savings in utility bills. Even if you have a tumble dryer, you should still try to line-dry outside, or rack-dry, whenever you can.
Many people are investing in heated clothes airers to speed up the drying process, as they cost a fraction of the price of tumble dryers to run. You might like to check out our article on the Best heated clothes airers for drying laundry 2025 to find out more.
Washing clothes on cold, quick, or eco-friendly cycles as much as possible will also get clothes just as clean, but use less energy to heat the water. It’s worth investing in a high-efficiency washing machine, too (A+ rated machines are best), as these also save water and money.
And finally – though it might sound obvious – try to wear clothes for longer before washing them. Of course, this doesn’t mean going around in dirty clothes! But many items of clothing don’t need to be washed after a single wear, so try to make sure the clothes you’re washing actually need it.

8. Buy second-hand
Buying second-hand is easier on your wallet and can have surprisingly powerful benefits for our environment.
Manufacturing new products increases the number of items sent to landfill, and also contributes to air pollution, greenhouse gas emissions, toxic waste, water pollution, and high water use.
Second-hand and charity shops are great places to buy clothes, shoes, books, and household items, but there are also many websites where you can buy second-hand items, from electronics to jewellery. Check out websites like Facebook Marketplace, Gumtree, Freecycle, Depop, Vinted, and eBay.
If you need to buy a new phone, laptop, or computer, it’s always smart to buy refurbished items – as not only are they cheaper, but they’re also usually as good as new.
9. Recycle or sell items
On a similar note, if you don’t wear certain clothes or shoes anymore, or would like to get rid of old devices or furniture, there’s no need to throw them out.
Putting items up for sale takes a bit of effort, but you’ll get money back, and no matter how much you may no longer want an item, that doesn’t mean no one else will. Remember, one person’s trash is another person’s treasure!
Our article, How to make money from your clutter, has plenty of tips on bringing in extra cash while giving new life to items you no longer use.
Even if you think you can’t sell an item, most recycling centres or local skips recycle old electronics, furniture, materials, and clothing, so it’s absolutely worth making the trip.

10. Buy from sustainable brands
It’s not always possible to find what you want in second-hand shops, so if you do need to buy new clothes, try to buy from sustainable clothing brands wherever you can.
Fast fashion is a huge threat to our planet, and in the UK, around 921,000 tonnes of material are thrown away in household waste each year.
If buying new, try to look for brands that use recycled or environmentally friendly materials like organic cotton, hemp, and soya fabric, or materials that have been made using renewable energy. While these items might cost a bit more upfront, they’re designed to last, so you won’t have to replace them for a long time, which can save you money in the long run.
To check out some of the UK’s most ethical and sustainable clothing brands, have a read of this article from Good On You.
11. Unplug and switch off
Most of us don’t know electricity is still flowing to devices like laptops and phones when they’re plugged in, even when switched off. So, once your devices are fully charged, make sure to unplug them – otherwise, you’re just wasting energy and money.
If you leave your phone charger plugged in even when you’re not charging it, try to get into the habit of unplugging it. Rather than leaving your TV on standby (which many of us are guilty of), switch it off when you’re not watching it. Try to turn the lights off when you leave the room, too.
Though these are all small actions, the energy and money you save will mount up over time.
12. Buy refills
Refill shops are quickly appearing all around the country, so why not take advantage of this and start buying refills of certain products?
Refill shops usually sell things like coffee granules, soap, shampoo and conditioner, herbs and spices, and food items like pasta, rice, and nuts.
Refilling the same reusable containers cuts down on plastic waste and usually costs less, too. To find your nearest refill or zero-waste shop, head over to Local Zero Waste.

13. Make your own cleaning products
Shop-bought cleaning products are usually full of toxins and unnecessary chemicals that, when poured down the drain or toilet, can harm the environment. Plus, they’re usually packaged in lots of plastic, and over the years, the amount we spend on cleaning solutions can mount up.
So why not save money and help protect the environment by making your own cleaning products?
This can be much easier than you may think, and often involves mixing ingredients you already have at home. DIY solutions work just as well as shop-bought ones – and once you start making your own, you’ll probably never go back to buying them!

14. Swap kitchen roll for washable clothes and sponges
Kitchen roll is a staple in many kitchens, but there is normally little need to have it. Instead of buying disposable paper products that cause unnecessary deforestation (and add to landfills), why not use washable clothes or sponges to mop up spills?
You can use old cloth or kitchen towels as your ‘utility towels’, and when dirty, just toss them in the washing machine (once it’s full, of course). Not only is this greener than using paper towels, but it’s also cheaper.
15. Take up cycling
Cycling is great for your health and saves money on fuel, public transport costs, and taxi fares – and is an effective way to reduce your carbon footprint.
While walking is also great for your health and the environment, some distances are just too far to get to on foot. So why not think about going on two wheels?
If you currently commute to work, you might want to check out the government’s Cycle to Work scheme, which gives you money off a new bike and can result in significant savings.

16. Consider switching to an electric car
For many of us, having a car isn’t a luxury, it’s a necessity – yet transport is responsible for nearly 30% of the UK’s total greenhouse gas emissions. While buying new petrol and diesel cars is set to be banned by 2030, why not get ahead and switch to an electric vehicle?
It may seem like a costly purchase right now, but in the long run, it could work out cheaper – and is significantly better for the planet. Plus, the government has introduced several discounts and tax incentives for electric vehicles, including drivers getting money off a new electric car via the plug-in grant.
To find out more, check out our articles: 10 of the best electric cars in 2025 and Should I buy an electric car?
17. Invest ethically
If you’re trying to save money, you might want to consider switching to an ethical bank or building society. It’s important to remember that when you have money in a current or savings account, the cash doesn’t just sit there waiting to be withdrawn; banks lend it to businesses that need financial support.
If you invest in ethical banks and building societies, they will always look at supporting green businesses first.
