Cutting back on red meat and dairy can be one of the biggest steps to reduce your carbon footprint. While Greenpeace campaign for renewable energy and a transition from fossil fuels, we're also looking at other ways we can protect ourselves and the environment.

Just like a fossil fuel transport system, the meat industry has an impact on the environment. When we eat red meat every day, it has an effect on our water use and carbon footprints.

According to the US Dietary Guidelines Advisory Committee's scientific report:

"Consistent evidence indicates that, in general, a dietary pattern that is higher in plant-based foods, such as vegetables, fruits, whole grains, legumes, nuts, and seeds, and lower in animal-based foods is more health promoting and is associated with lesser environmental impact (GHG emissions and energy, land, and water use) than is the current average US diet."

So why start a low-carbon diet, and where do you begin making changes? Check out these great tips on how to cut back on meat.

1. Your diet, your rules

Your diet is a very personal part of your life. That means you don't need to follow the rules and trends of other herbivores – just the advice of your doctor (and maybe your mother). Some vegetarians choose to eat sustainably caught seafood, and some vegans eat eggs from their own chickens. Others – called 'freegans' – eat meat and dairy that would otherwise be thrown out to avoid food waste. As long as you're safe, healthy, and making the decisions you want for yourself and the world, you're all good.

2. It's okay to start slow

If dropping meat from your diet right now sounds daunting, you can try phasing it out over time. Initiatives like Meatless Mondays, where people stop eating meat one day of the week, are a great place to start (not to mention you'll be alongside people like Sir Paul McCartney and Chris Martin). You could also make an effort to choose the vegetarian option when eating out, or start by cutting the most resource-intensive meats like beef from your diet.

3. Talk to friends and loved ones

Sometimes our diets affect the people we live with or see a lot. If you're sharing food preparation duties with someone, make sure you talk to them about your decision and make an effort to work out a plan. Maybe some nights you'll cook separately, or you'll make dishes with the meat on the side – or they might even make a change with you!

If you're visiting friends or family for a meal, let them know about your new diet. You might want to bring a vegetarian dish or two to share, or offer to come early to help cook and prepare. Your diet doesn't have to stop you from enjoying your life.

5. What if I can't cut back on meat right now?

If you can't stop eating meat, but still want to bite away at your food footprint, there's still lots you can do. You might choose to buy local or organic produce, stop eating processed or packaged foods, or grow your own fruit and vegetables at home. There are even ways to make changes to how you consume meat and dairy to reduce your carbon food footprint, like choosing from more ecological farming methods such as buying grass-fed rather than grain-fed beef.

Making the decision to commit to a new diet is difficult – but once you start it's easy! But if you slip up or forget, be kind to yourself and keep at it.
