On some images you'll see a blue double-ended arrow icon. Clicking or tapping on this will expand the picture so you can see more detail. Click or tap on the blue cross to close the expanded image.

Where we think a group of images will be most useful to you, we've grouped them together in an image gallery. Simply use the blue left and right arrows to scroll through the carousel of pictures.

Decide what's for dinner

The good news is that you can make mealtimes more eco-friendly without having to compromise on choice or taste

All foods have an environmental impact, but eating more sustainably is not as difficult as you might think. Did you know that eating beef one or two times a week over a year has the same environmental impact as a return flight from London to Malaga? Small actions make a big difference and, importantly, it doesn't have to be all or nothing.


Simply planning your weekly meals to include more seasonal vegetables and fruit grown in the UK is one option. Or, instead of following a meat recipe every evening, at least once a week aim to have a plant-based meal using pulses, legumes, tofu, quorn or a soya mince in place of animal products. Meat-free alternatives are a great way to do this – read up on our reviews of the best vegan burgers and the best vegan and vegetarian sausages to find out which to go for.

Know your food's carbon footprint

Animal products have a higher carbon footprint Carbon footprintThe amount of carbon dioxide (or the equivalent in other greenhouse gases) released into the atmosphere as a result of the activities of an individual or organisation than plant foods thanks to the way animals are farmed and the methane they expel, along with fertilisers used on the land and everything that goes into growing their feed. So take a look at what's on your plate. Producing 1kg of beef creates 59.6kg of greenhouse gases Greenhouse gasNaturally and human-produced gases, including carbon dioxide, that trap heat in the atmosphere and warm the Earth’s surface, contributing to global warming and 1kg of cheese creates 21.2kg. At the other end of the scale, peas and nuts create less than 1kg of greenhouse gases per kilo. Swap some of the items at the top of this table for others lower down and you’ll be making a difference.

However, carbon footprint shouldn't be your sole consideration. Land and water use also increase the environmental impact of what we eat and drink.

Got milk?

Although more plant-based milk substitutes are appearing on supermarket shelves, it’s worth noting that some of these products also take their toll on the environment and there are several factors to consider. Almond milk, for example, has a low carbon footprint, yet its water footprint is very high – 15 gallons of water are needed to grow just 16 almonds. Soya has been scrutinised in recent years as a crop heavily linked to the deforestation of the Amazon rainforest, but most soya milk brands available in the UK exclusively source their soyabeans from the USA, Canada or Europe, meaning it has one of the lowest overall impacts.
