A guest post to help you lower your carbon impact by Louise Palmer-Masterton, Stem & Glory. 

If you want to help bring about positive change regarding the environment and the limited resources of the planet, you can start with hummus. But before we get to that, here are a few other ways you can make a big difference.

Support British grown produce

Remarkably, we import 70% of the apples we eat, when the UK is the most perfect climate for growing apples. We have fallen out of synch with our own climate and lost a great deal of produce in the process.

In medieval times we grew a wide variety of pulses, grains and peas. Luckily for us, these are now coming back. Champions of this produce – Hodmedods – has an ever-growing array of beautiful British grown produce for sale.

With greater demand for UK grown produce, more farmers will grow it, and less food will be grown to feed to animals (a highly inefficient way to feed people) – a win-win for everyone and great way to lower your carbon impact! Hodmedods also believes in working in harmony with farmers so they are paid fairly and not constantly squeezed on price.

Move to a 100% renewable energy tariff

The most significant step anyone can take, both in their home or business is to move your energy supply to a 100% renewable tariff. If you combine this move with energy-saving actions, such as LED lights, and energy-saving devices, the increased cost of these tariffs can be offset by behaviour change. 

Don’t underestimate the power of many small actions combined to make a significant difference. For example, if the oven is on, utilise it to cook more food than just one meal on one shelf.

You can retrain your mind to question if every single energy use is necessary. I was gifted an air fryer last Christmas, and it’s amazing how little we use our main oven now. The air fryer cuts cooking times too, and you can cook many different things in it.

Reduce consumption, and reduce waste

When you are shopping, ask yourself these three questions every time you pick up something:

Do I really need this?

Where was this made?

What happens to this when I no longer need/want it (in the case of food, what happens to the packaging)?

Base your purchasing decisions on your answers to these questions. It’s not about being 100% perfect, but in this way, you can train yourself into better buying habits, and it’s amazing how fast this process can change your mindset and lower your carbon impact.

Reduce your own use of single-use

Get yourself a lunch box and a reusable cup and take it everywhere with you instead of using single-use items.

Use the lunchbox to take your own lunch, but also carry an empty lunchbox – restaurants and cafes are often very happy to fill your box rather than a take-away box, and it’s very handy to take restaurant leftovers.

It’s surprising how quickly you can wean yourself off single-use, so it becomes a very occasional, rather than daily, habit.

The fastest way to bring about collective change is via our demands as a consumer. If we buy products in paper, card, glass and aluminium and shun products in plastic, this will drive the market.

Avoid grab and go for your working lunch

The nature of grab-and-go means it will always involve single-use. Consider the sheer volume of single-use in just one lunchtime up and down the UK.

Doesn’t matter if it’s ‘biodegradable’ – biodegradable packaging doesn’t solve the huge issue of mass disposability and the huge amount of energy that is wasted when something is used once and then thrown away.

Recycling is not the answer. Eliminating single-use is the answer to lower your carbon impact. Consider supporting cafes and restaurants by eating in rather than at your desk. Food eaten off a plate tastes better too!

Eat more plants, and eat seasonally

The sheer variety of produce we can get year-round is amazing, but as we are starting to realise, very unsustainable. Market forces have driven these unsustainable import and export practices.

Whilst it is true that simply by being vegan you will lower your emissions, not all vegetables are equal. It’s important to understand the cycle of the seasons and eat veg in harmony with that.

Imported food isn’t always bad, but the mode of transport is important. Slow is good, fast is bad. So, if something is not in season here, and it has a short shelf life, 100% it will have been flown here – so best to avoid it. 

Here is a delicious, plant-based, low carbon, recipe using UK grown produce, to get you started: 

Yellow Pea Hummus

Hummus is one of the nation’s best-loved dips, but chickpeas do not grow very well in our climate, so they are nearly all imported. The good news is British yellow peas grow amazingly well here, they make fantastic hummus, and they are even more nutritious than chickpeas.

They also blend a lot better, which is one of the main reasons I never made chickpea hummus at home – I just couldn’t get that whipped consistency with chickpeas.

The yellow peas do it perfectly though. Making a pot of this every week instead of buying plastic and cardboard wrapped deli pots from the supermarket, will instantly improve your sustainable credentials.


  • 250 grams cooked whole British yellow peas (buy from Hodmedods, soak for 5 hours, drain and cover with fresh water and boil for 45 mins, drain and retain the drained water)
  • 60 ml lemon juice
  • 60 ml tahini
  • 1 small garlic clove
  • 30 ml British oil
  • 1/2 tsp ground cumin
  • Salt to taste (start with ½ tsp)
  • 50 to 90 ml pea cooking water


Add the first 7 ingredients to a blender and blend for 2 minutes. Then with the blender still turning, add 50ml of the pea water slowly. Blend until very smooth. 

Making your own hummus may not seem like it will make a huge difference, but if we all make our own small efforts the impact will be massive. There are of course big changes that need to happen on a global scale, and science is very much at the start of its journey towards cleantech and carbon capture. But as individuals, we exert huge influence as consumers and by questioning all our own personal habits.
