A climate-friendly diet prioritizes foods with lower environmental impact—like plant-based, local, and upcycled ingredients—to reduce greenhouse gas emissions without sacrificing nutrition or flavour. You can start today by swapping everyday staples like bread for upcycled alternatives that rescue food waste and support local food systems.
What is a climate-friendly diet?
A climate-friendly diet focuses on choosing foods that produce fewer greenhouse gas emissions throughout their life cycle—from farm to plate to disposal. This typically means prioritizing plant-based foods over animal products, choosing local and seasonal options to reduce transportation emissions, and selecting items made with upcycled ingredients that prevent food waste from ending up in landfills where it produces methane.
Food systems account for roughly one-third of global greenhouse gas emissions, and individual food choices can make a measurable difference. A climate-friendly approach doesn’t require perfection or extreme restrictions—even small swaps in your daily routine can reduce your carbon footprint while keeping meals delicious and nutritious.
Why local and plant-based foods matter
Plant-based foods generally require fewer resources and generate lower emissions than animal-based products. Beef production, for example, produces roughly 60 kilograms of greenhouse gas emissions per kilogram of meat, while lentils produce less than 1 kilogram. Shifting toward more plant-forward meals—even just a few times per week—can significantly reduce your dietary carbon footprint.
Buying local cuts down on transportation emissions and supports local food systems – farmers, bakers, and food producers in your community. When you choose products made nearby, you’re investing in local resilience and keeping food dollars circulating close to home. Local food systems also tend to waste less because supply chains are shorter and products move from producer to consumer more quickly.
Combining local with plant-based creates an even stronger impact, especially when those products tackle food waste at the same time.
The power of upcycled foods in a climate-friendly diet
Upcycled foods are made from ingredients that would otherwise go to waste—edible by-products from food production that still contain valuable nutrients but traditionally end up as animal feed or in landfills. When organic matter decomposes in landfills without oxygen, it produces methane, a greenhouse gas 25 times more potent than carbon dioxide over a 100-year period.
By rescuing these ingredients and turning them into human foods, upcycling prevents waste, reduces methane emissions, and makes use of resources that have already been grown and processed. Brewers’ spent grain is a perfect example: after breweries extract sugars from barley to make beer, the remaining grains are still packed with fibre, protein, and micronutrients—ideal for baking into breads, crackers, and other everyday foods.
Upcycled foods fit seamlessly into a climate-friendly diet because they tackle waste at the source, support local circular economies, and deliver nutrition without requiring additional agricultural resources.
Health benefits of a climate-friendly diet
A climate-friendly diet isn’t just good for the planet—it’s often healthier for you too. Plant-based diets rich in whole grains, legumes, vegetables, and fruits are associated with lower risks of heart disease, type 2 diabetes, and certain cancers. These foods tend to be higher in fibre, vitamins, minerals, and antioxidants while being lower in saturated fats.
Upcycled ingredients like spent grain add even more nutritional value. Spent grain is roughly 70% fibre and 20% protein, making it a nutrient-dense addition to breads and baked goods. Fibre supports digestive health, helps stabilize blood sugar, and keeps you feeling full longer—benefits that align perfectly with both personal wellness and environmental goals.
Eating for the climate doesn’t mean compromising on flavour or nutrition. In fact, many climate-friendly foods offer superior taste and health benefits compared to heavily processed alternatives.
Simple ways to start a climate-friendly diet today
You don’t need to overhaul your entire pantry overnight. Start with small, practical swaps that fit into your existing routine:
- Swap your regular bread for upcycled bread made with spent grain. It’s higher in fibre and protein, and every loaf you buy helps prevent food waste from ending up in landfills.
- Add one or two plant-based meals to your weekly rotation. Try lentil soups, bean-based tacos, or vegetable stir-fries with tofu—simple, budget-friendly options that deliver nutrition and flavour.
- Shop at local farmers’ markets, co-ops, or independent grocers that prioritize local and sustainable products. Building relationships with nearby producers makes it easier to source climate-friendly foods regularly.
- Choose seasonal produce whenever possible. Seasonal fruits and vegetables require less energy to grow and transport, and they’re often fresher and more affordable.
- Look for the Upcycled Certified label on packaged foods. This certification identifies products made with ingredients that would otherwise be wasted, making it easy to support circular food systems at the grocery store.
These simple changes add up quickly, especially when multiplied across households and communities.
How Spent Goods fits into your climate-friendly diet
Spent Goods makes it easy to integrate upcycled, local, and plant-based foods into your daily meals. We partner with Ontario breweries to rescue spent barley grains before they become waste, then work with local bakers to transform them into delicious breads, burger buns, and other staples.
Our products check all the boxes for a climate-friendly diet: they’re plant-based, made locally, and upcycled from ingredients that would otherwise contribute to greenhouse gas emissions. Every loaf of Spent Goods sourdough or package of burger buns represents grains rescued from landfills, methane emissions prevented, and local jobs supported.
Choosing Spent Goods also means eating foods that are healthier for you. Our spent grain breads contain 2-3 times more fibre than conventional white bread, plus extra protein, magnesium, iron, and zinc—making them a nutritious upgrade to your everyday sandwiches, toast, and burgers.
By incorporating Spent Goods into your routine, you’re not just making a purchase—you’re participating in a circular food system that keeps nutrients in the local loop and tackles climate change one slice at a time.

Frequently asked questions about climate-friendly diets
Not at all. A climate-friendly diet is flexible and focuses on reducing your environmental impact through practical swaps, not perfection. Even small changes—like eating more plant-based meals a few times a week or choosing upcycled products—can make a meaningful difference. The goal is progress, not an all-or-nothing approach.
Local food generally has a smaller carbon footprint because it travels shorter distances, reducing transportation emissions. However, the type of food matters more than distance. For example, plant-based foods grown far away typically have lower emissions than locally raised beef. The biggest climate wins come from combining local sourcing with lower-impact food types—like choosing local, upcycled breads instead of imported processed snacks.
Absolutely. Upcycled foods are made from ingredients that were always intended for human consumption but traditionally went to lower-value uses or waste. They must meet the same food safety standards as any other products. Spent Goods products, for example, are made in licensed bakeries following strict food safety protocols
