Sometimes it can be easy to become too satisfied when it comes to living sustainably. We may all have recycling bins in our kitchens, but here are some ways you can live more sustainably.

1. Put an end to plastic water bottles and one-off coffee cups

The only way this is going to work is that if you have reusable options you really love, invest in a great water bottle. This is an advance payment, but it will save you money in the long run. A 750ml bottle of Evian costs 90p in Tesco, meaning if you buy one every two days you could save £10 within three weeks by filling up a reusable bottle at home.

2. _______________________________________

The high street is problematic on so many different levels. Not only are you buying items with questionable supply chains, but the carbon footprint of each product is shocking as well. Online shopping is even worse, with overpackaging for each item and the emissions from delivery trucks. The answer is to stick to reach-me-down or previously owned items as much as possible. Not only will this save you money, but there’s also a sense of satisfaction in finding a hidden treasure from the flea market where you find outstanding bargains or something used, which you simply can't get from shopping in Wal-Mart or on Amazon.

3. Think hard about your transportation

Even if your car is supposedly a low-emissions model, it’s still going to be a huge contribution to your carbon footprint. There are times when getting in a car can’t be avoided, but if you can substitute just one flight a year with a train, one car journey a week with a bus. and one bus a month with a bike ride, you’ll find that making more mindful transport decisions can easily make your day-to-day life more environmentally friendly with little effort.

4. Try to buy local, seasonal produce

You may think buying strawberries in December or courgettes in spring is no big deal, but the chemicals and fuel used to artificially copy the right environment for them to grow create harmful gas emissions. Similarly, the environmental impact of transporting produce from another country is huge. Buying from local farmers also means you can often ignore the huge amounts of packaging the supermarkets use.
