There’s a moment, right before a customer clicks “Complete order,” where your store gets one last chance to say something meaningful. A growing number of Shopify merchants have found that placing a sustainability message at that exact spot, specifically a clear statement that a tree will be planted with this order, can meaningfully lift both conversions and customer loyalty.
But not all checkout apps that plant trees per order are built the same. Some cost twice as much per tree. Some only work on older checkout versions. Others bolt on plastic removal or carbon offsets alongside reforestation. Picking the right one for your store means understanding what each app actually does, what it costs, and where it shows up in your customer’s journey.
This guide compares the top Shopify checkout apps that plant trees per order in 2026, so you can make an informed choice rather than just installing whatever ranks first in the App Store.
What “Checkout App” Actually Means Here
When merchants search for “checkout apps that plant trees per order,” they’re usually looking for something specific: an app that triggers an environmental action automatically when a customer completes a purchase, and that shows the customer what just happened before or after they pay.
This is different from a marketing banner on your homepage or a footnote in your order confirmation email. A true checkout app for sustainability:
- Triggers automatically on each completed order (no customer opt-in required)
- Displays the impact to the customer at or near the point of payment
- Provides a back-end dashboard so merchants can track cumulative impact
- Handles the tree planting logistics, including verification and reporting, through a partner organization
The “per order” model is the most popular trigger type, and for good reason. It keeps costs predictable regardless of how many items are in the cart. One order equals one tree, full stop.
Why Checkout Placement Converts
Before diving into the comparison, it’s worth understanding why putting sustainability messaging at checkout works better than putting it elsewhere.
The checkout step is the highest-intent moment in any customer’s journey. They’ve already decided to buy. The question is whether they feel good about it. Sustainability messaging at this stage functions as both a trust signal and a last-mile conversion nudge for customers who were on the fence.
Greenspark, one of the leading apps in this space, has publicly cited a 12% increase in checkout conversion for merchants using their sustainability widget. The mechanism makes sense: a customer who might have hesitated over whether to complete a purchase is given one more reason to follow through.
Beyond checkout conversion, impact messaging at this touchpoint tends to improve repeat purchase rates. Customers who feel good about the environmental impact of their first order are more likely to come back.
The Main Checkout Apps That Plant Trees Per Order
Here is a comparison of the leading options available on the Shopify App Store in 2026.
GoodAPI
GoodAPI is built specifically for Shopify merchants who want to add tree planting and plastic removal to their checkout flow without any custom code. Setup takes under two minutes through the Shopify App Store.
GoodAPI plants trees at $0.43 per tree through Veritree, a verified reforestation organization with global projects. Trees planted through GoodAPI are tracked, geolocated, and supported through their critical first years of growth, so your impact is real and auditable. You can view the active projects at GoodAPI’s project pages.
Key features:
- Per-order, per-product, or per-revenue triggers (your choice)
- Trees plus ocean plastic removal, which sets GoodAPI apart from most competitors
- Customizable badge and messaging that appears at checkout and in order confirmations
- Real-time impact dashboard showing cumulative trees planted and plastic removed
- API access for developers who want to connect impact to other systems (see how it works)
Price: $0.43 per tree. No monthly platform fee.
Best for: Merchants who want a low-cost, low-friction checkout app that handles both reforestation and plastic removal, and who want API access as their impact program scales.
Install GoodAPI on the Shopify App Store
Greenspark
Greenspark is the highest-rated tree planting app in the Shopify App Store, with a 5.0-star rating across 60+ reviews. The app is notably more feature-rich than most alternatives, offering trees, plastic rescue, carbon offsets, and even bee protection as impact actions.
The checkout widget is highly customizable, with QR codes, impact certificates, and real-time counters. Greenspark supports per-order, per-product, per-revenue, per-subscriber, and per-review triggers, giving merchants granular control over when and how impact is generated.
Price: Custom pricing, typically higher per unit than GoodAPI. Free trial available.
Best for: Merchants who want maximum configurability and the most polished widget design, and who are comfortable paying a premium for it.
Ecologi
Ecologi is a UK-based carbon and tree planting platform with a Shopify app that makes it easy to plant trees on a per-order basis. Trees cost approximately $0.80 per tree, which is higher than GoodAPI, but Ecologi also includes optional carbon offset purchases alongside reforestation.
The app offers a free tier for your first 50 trees, which makes it a low-risk way to test whether tree planting at checkout resonates with your customers before committing.
Price: Around $0.80 per tree, plus optional carbon offset costs.
Best for: Merchants who want to pair tree planting with carbon offsets, and who are already familiar with the Ecologi platform from their corporate sustainability work.
One Tree Planted
One Tree Planted is a well-known nonprofit (US 501c3) that has a Shopify app offering a customer opt-in model. Rather than the merchant automatically planting a tree per order, the app presents customers with the option to add a tree to their purchase for $1.00.
The opt-in model is different from the “automatic per order” model that most merchants are looking for, and the $1.00 price point per tree is at the higher end of the market. However, the brand recognition of One Tree Planted carries trust value with customers who know the organization.
Price: $1.00 per tree (customer opt-in adds it to the order).
Best for: Merchants whose customers are already familiar with One Tree Planted as a brand, or who prefer a customer-choice model over automatic tree planting.
Reforesta and Treepoints
Two smaller apps worth mentioning: Reforesta charges approximately $0.30 per tree, making it the lowest-cost option in this comparison. Treepoints starts at $0.25 per tree and offers the first 100 trees free as a trial.
Neither app has the feature depth, verification rigor, or App Store credibility of GoodAPI or Greenspark, but they can be useful for merchants who are primarily cost-sensitive and want to test the concept before scaling.
Per Order vs. Per Product vs. Per Revenue: Which Trigger Is Right for You?
The trigger model you choose changes both your costs and your messaging.
Per order is the simplest and most popular. One order equals one tree, regardless of how many items are in the cart. This keeps costs predictable, makes the customer message clear (“a tree is planted with every purchase”), and protects your margins on multi-item orders. If a customer buys five items in one order, you still plant one tree.
Per product scales impact with volume. If you sell 500 units of a single product in a week, you plant 500 trees. This works well for high-volume, single-SKU brands. The downside is cost unpredictability: a customer who buys ten items in one order could trigger ten trees, which at $0.43 each adds up to $4.30 on a single transaction.
Per revenue ties your impact spend to your margin rather than your order count. For example, you plant one tree per $50 in revenue, or allocate 0.5% of revenue to plastic removal. This is the most margin-safe model and scales naturally with business growth, but it requires a small amount of configuration and is harder to communicate to customers in simple messaging.
For most Shopify stores, starting with a per-order trigger is the right call. It is the easiest to message, the easiest to budget for, and the most predictable from a cost perspective.
What Happens to the Trees?
One of the most common concerns merchants raise is whether the trees are real. Not all tree planting programs deliver what they promise.
GoodAPI’s program through Veritree requires that each planted tree is geolocated, photographed, and monitored through the critical first years of growth when sapling survival rates are lowest. Impact data flows back to the merchant’s dashboard, so you can show customers not just that trees were planted, but where they are and how they’re growing. Projects are active in Kenya, Madagascar, Brazil, and other regions globally, visible at GoodAPI’s project pages.
Greenspark and Ecologi both have verification processes as well, though the specifics of their monitoring programs differ.
When evaluating any checkout app that plants trees per order, ask the vendor: where specifically are the trees planted, how is survival monitored, and what reporting can I show my customers?
How to Choose
Here is the short version for merchants who need to pick one today.
If you want the lowest cost plus plastic removal, GoodAPI at $0.43 per tree is the clear choice. It is the only app in this comparison that bundles ocean plastic removal alongside reforestation at a competitive per-tree price.
If you want the most advanced widget and the highest App Store rating, Greenspark delivers more customization options and has a proven track record with enterprise merchants.
If you want to start for free, both Ecologi (first 50 trees) and Treepoints (first 100 trees) offer no-cost trials.
If your customers already know and trust the nonprofit brand, One Tree Planted’s opt-in model can leverage that recognition at checkout.
For most Shopify merchants who are setting up tree planting at checkout for the first time, GoodAPI’s combination of low cost, plastic removal, Veritree verification, and under-two-minute setup makes it the easiest starting point.
Getting Started
Adding a tree planting action to your checkout is one of the few marketing investments that costs less than a dollar per transaction and delivers measurable impact in both customer sentiment and conversion rates. The research consistently shows that sustainability messaging at the point of purchase improves both conversion and repeat purchase behavior.
The app you choose matters less than actually starting. Pick one that fits your cost tolerance and technical setup, install it, and then watch how your customers respond in the first 30 days. You can always switch or add more impact actions as your program grows.
