PackageCarbon: Shipping Emissions Validator
Automatically calculates and displays carbon emissions for each shipping option at checkout, letting e-commerce customers choose lower-impact delivery.
The Problem
E-commerce businesses want to offer sustainable shipping options but lack easy ways to calculate accurate emissions per carrier/speed tier. Customers want to make greener choices but have no visibility into the carbon cost of overnight vs. standard shipping at purchase time.
Target Audience
Mid-market e-commerce brands (Shopify/WooCommerce stores with $500K-$5M ARR) selling physical products who want sustainability credentials without complex integrations.
Why Now?
Shopify's June 2024 Checkout Extensions update made native checkout customization easier for vibe coders. Major carriers (UPS, FedEx) now publish carbon data APIs. Brands face increasing pressure to label product impact.
What's Missing
Existing carbon calculators are post-purchase or require manual input. No app seamlessly inserts emissions into the shipping method selector at checkout where customers actually make decisions.
