Are Meal Kits Really Eco-Friendly? Unpacking the Environmental Impact
Explore whether meal kits offer genuine environmental benefits—and how they stack up against traditional groceries in waste, packaging, and emissions.
Are Meal Kits Really Eco-Friendly?
As meal kits become a fixture in modern kitchens, questions abound regarding their impact on the environment. Once critiqued for their excessive packaging, meal kits are now being re-examined for their potential to reduce food waste and overall carbon emissions. Do these boxes delivered to your door genuinely advance sustainability, or is it mostly clever marketing? This article unpacks the available evidence on how meal kits stack up against conventional grocery shopping, considering emissions, waste, packaging, and more.
What Are Meal Kits?
Meal kits are subscription-based services that deliver pre-portioned ingredients for selected recipes directly to a consumer’s home. Popular brands include Blue Apron, HelloFresh, and Sunbasket, covering a wide array of dietary preferences—from omnivore to plant-based, single-serve to family-sized portions. Since their introduction in 2012, the industry has expanded rapidly, with sales reportedly reaching billions annually.
The Environmental Footprint Debate
At first glance, meal kits seem to generate an outsized environmental footprint due to their visible mountains of packaging. Critics argue that single-use plastics and non-recyclable materials turn ordinary meals into environmental hazards. However, recent peer-reviewed studies have revealed that, when considered across the entire supply chain, meal kits may actually be the greener choice compared to conventional grocery shopping.
Carbon Emissions: Meal Kits vs. Grocery Stores
One pivotal University of Michigan study illuminated the carbon cost of meal kits. Researchers factored in every stage—from agriculture through delivery and eventual food disposal. The shocking result: a meal kit’s carbon footprint averaged just 6.1 kg CO2, roughly 33% lower than the equivalent grocery-sourced meal at 8.1 kg CO2.
- Reduced Food Waste: Grocery purchases often result in surplus food that is never consumed and ultimately tossed away. Meal kits, by contrast, provide precise portions, vastly minimizing this waste.
- Efficient Supply Chain: Meal kit companies optimize procurement and logistics, reducing energy spent on bulk retail operations such as overstocking and refrigeration at supermarkets.
- Direct-to-door Delivery: While intuitive logic suggests delivery trucks might add emissions, consolidated deliveries performed by meal kit services tend to outpace the efficiency of many separate individual grocery store trips.

| Meal Type | Carbon Footprint (kg CO2) |
|---|---|
| Meal Kit | 6.1 |
| Grocery Store | 8.1 |

Food Waste: A Key Advantage
Globally, food waste is a massive issue. In the UK, for example, 3.6 million tonnes of food is wasted by the food industry annually, translating to over 7% of all harvested food. US households throw away about 30% of purchased food. Much of this is due to buying more than needed, food spoilage, and imperfect meal planning.
- Meal kits minimize waste by sending exactly the right portions needed for a recipe. No leftovers languish in the fridge or go bad before use.
- According to recent research, supermarket meals are responsible for 33% more greenhouse gas emissions than meal kits, mainly due to excess food waste.
This waste reduction is one of the strongest arguments for the eco-friendliness of meal kits.

Packing Up the Problem: Packaging Concerns
If there’s one area where meal kits are routinely criticized, it’s packaging. Pre-portioned ingredients often arrive in multiple plastic sachets, cardboard boxes, and insulation liners. While this enables freshness and convenience for consumers, it produces a surprising volume of packaging waste.
- Much packaging is not biodegradable or recyclable, contributing to landfill and even aquatic pollution.
- Small plastic containers, insulation, and cold packs can accumulate quickly, especially for frequent users.
- Consumer frustration with packaging has led to calls for improvement in reusable, compostable, and eco-friendly solutions.
However, some meal kit services have made strides in sourcing recyclable materials and reducing packaging complexity. For example, Sunbasket and Green Chef emphasize organic ingredients and more sustainable packaging options.
Supply Chain Efficiency and Transportation
Most environmental analyses extend beyond the kitchen to the supply chain and transportation. The energy expended at supermarkets—from lighting and refrigeration to overstocking and food spoilage—can produce substantial emissions. Meal kit companies, by contrast, streamline procurement, inventory, and refrigerated transportation more efficiently.
- Supermarkets often discard blemished produce and overstocked items, adding to systemic waste.
- Meal kits bypass traditional retail logistics, leading to fewer emissions from operational overhead.
- Meal kits consolidate deliveries, often resulting in fewer transportation emissions than multiple consumer trips.
Real-World Examples: Comparing Meals
The studies cited compared meal kits and store-bought equivalents, analyzing five Blue Apron recipes head-to-head with grocery store journeys. Their findings:
- Four out of five meal kits produced fewer greenhouse gas emissions than the grocery store versions.
- The exception was a cheeseburger kit, where beef’s high carbon cost and heavier ingredients tipped the scales towards greater emissions.
- Plant-based and vegan kits show consistently lower impact compared to meat-heavy options.
Thus, the specific recipes and sourced ingredients significantly influence environmental performance—for both meal kits and groceries.
Innovations and Improvements in Eco-Friendly Meal Kits
A growing number of companies make sustainability a central selling point. Some offer:
- Organic and local sourcing (e.g., Sunbasket, Green Chef)
- Plant-based and vegan options to further cut emissions
- Investments in compostable and recyclable packaging
- Charity partnerships (e.g., donations to Feeding America) to help combat food insecurity
As consumer demand for green products rises, meal kit providers are improving their sustainability efforts all the time.
Meal Kits and the Issue of Food Insecurity
While reducing environmental impact, it’s important to consider the relationship between meal kits and food insecurity. According to the USDA, up to 50 million Americans may experience food insecurity, exacerbated by the pandemic. Waste reduction and better logistics—and partnerships with charitable organizations—could make meal kits a part of the solution.
- Several meal kit companies have launched initiatives to combat hunger, such as donating meals through organizations like Feeding America.
- This effort addresses the paradox of food surplus and hunger by redirecting unused resources.
Balancing Convenience, Cost, and Sustainability
Consumers choose meal kits for many reasons—convenience, high-quality ingredients, variety, and ease of use. Eco-friendliness is an increasingly important factor. While meal kits are still imperfect, notably on packaging, their contribution to reducing food waste and overall emissions contrasts favorably with standard grocery shopping.
- Perfectly portioned meals mean less overbuying and fewer spoiled ingredients.
- High-quality, often locally sourced food delivers fresh produce and proteins at a competitive price.
- Committed eco-friendly brands offer greater sustainability than mainstream grocery stores.
What to Look for in an Environmentally-Friendly Meal Kit
If you’re considering subscribing to a meal kit, here’s how to pick an option that’s genuinely eco-conscious:
- Check for organic or local sourcing.
- Research the sustainability of packaging: look for recyclable, reusable, or compostable materials.
- Prioritize plant-based meals for a lower carbon footprint.
- Support companies involved in charitable food distribution.
- Choose kits with carbon offset programs or other environmental pledges.
Frequently Asked Questions (FAQs)
Q: Do meal kits really help reduce food waste?
A: Yes. Meal kits employ precise portion control, substantially cutting food waste compared to grocery store shopping, where surplus ingredients are often discarded.
Q: Is the packaging from meal kits always harmful for the environment?
A: Not always. While meal kits use substantial packaging, especially small plastics, many companies are transitioning to recyclable, reusable, or compostable materials. Packaging waste remains a concern, but ongoing improvements are underway.
Q: Which is better for the climate—meal kits or grocery store shopping?
A: On average, meal kits produce around 33% fewer greenhouse gas emissions than equivalent store-bought meals, thanks to reduced food waste and more efficient logistics.
