MEASURE YOUR ECOMMERCE WEBSITE'S CARBON FOOTPRINT
Ecommerce sites are among the heaviest on the web. High-resolution product images, video, retargeting scripts, and live inventory feeds all add up. Track your store's CO₂ output, find the biggest offenders, and demonstrate progress to customers who care.

The average ecommerce product page transfers 2–5MB of data per load — far above the web average. The main contributors:
Product images
Multiple high-res angles, zoom views, and color variants. Often unoptimized or served at desktop resolution even on mobile.
Product videos
Autoplay demo videos and 360° spins. A single 30-second product video can add 20MB+ per page load.
Analytics and retargeting pixels
Facebook Pixel, Google Ads, Klaviyo, TikTok — each tag loads its own script and fires its own requests. A typical ecommerce site has 8–15 active tags.
Payment and review widgets
Third-party checkout buttons, star-rating embeds, and trust badge scripts each add their own weight.
Live inventory and pricing
Dynamic content that requires server-side calls, often implemented with heavy JavaScript polling.
Monitor the Pages That Matter Most
Your homepage isn't the only page that counts. With MyCarbonScan, you can monitor specific high-traffic pages across your store:
→
Homepage
→
Top product pages (your best sellers by traffic)
→
Category and collection pages
→
Checkout flow
→
Blog posts and buying guides
Up to 100 URLs on a single plan, rescanned automatically every night.
The Sustainability Data Your Customers Are Starting to Ask For
Consumer expectations around brand sustainability are shifting. Ecommerce brands that can point to a specific, measurable, tracked carbon metric — "our product pages produce X grams of CO₂, down from Y last quarter" — are in a fundamentally stronger position than those making vague claims.
MyCarbonScan gives you time-series data you can stand behind. Export a CSV of your scan history and include it in sustainability disclosures, annual reports, or your brand's transparency page.
Optimization: What Moves the Needle for Ecommerce
Convert images to WebP or AVIF
Typically reduces image transfer by 30–50% with no visible quality loss. This is usually the single highest-impact change on product-heavy pages.
Implement lazy loading for images below the fold
Don't transfer what the user hasn't scrolled to yet. Most ecommerce platforms support native lazy loading natively.
Audit your tag manager
Do a quarterly review of every tag firing on your storefront. Unused retargeting pixels for campaigns that ended months ago are common and easy to remove.
Self-host or defer third-party scripts
Load analytics tags asynchronously. Move from synchronous to deferred loading so tags don't block rendering.
Reduce video autoplay
Replace autoplay videos with a static image and a play button. Users who want to see the video will click; everyone else saves 10–50MB of transfer.
