CH4MBER

Carbon-Neutral Spend for Shopify

Issued-credit integrity workflow

Give every ski, snowboard, and outdoor order a credible carbon-neutral option.

Ch4mber Carbon Neutral helps outdoor brands offer a clear, optional contribution backed by verified methane-abatement credits, with claim completion gated by issued inventory and retirement evidence, while Ch4mber retains control over pricing and credit operations.

Optional contribution, clear buyer math, issued-credit checks, retirement-first claim completion, Ch4mber-managed economics.

How it works

1

Customer opt-in

Present a clear optional contribution at product and cart, never as a forced fee.

Why it matters

Keeps consent explicit and merchant-safe.

2

Issued-credit gate

Orders check issued inventory availability before claimable status appears.

Why it matters

Prevents over-claiming against available inventory.

3

Retirement evidence

Carbon-neutral completion is finalized only after retirement records are complete.

Why it matters

Claims are tied to auditable evidence, not assumptions.

How calculation works

Example: a 10kg ski order with outdoor factor 12 estimates to 120kg CO2e. At $0.25/kg, the optional contribution shown to the buyer is $30.00.

Step 1

Shopify product context

Reads product type, variant weight (grams), quantity, and line price from product/cart context.

Why it matters

Uses native storefront data you already maintain.

Step 2

Estimation model

If weight is available, estimate uses weight × category factor. Outdoor terms like ski/snowboard map to the outdoor factor with a 10kg default when weight is missing.

Why it matters

Works on day one and improves as product data quality improves.

Step 3

Contribution pricing

Estimated kgCO2e is priced by Ch4mber’s current program rate and shown as a simple No thanks / Add $X choice.

Why it matters

Buyers keep explicit choice while pricing stays operationally consistent.

FAQ

Does this force contributions on every order?

No. Buyers can choose to contribute, and the checkout remains optional.

When is an order considered carbon neutral?

Only after retirement evidence has been completed and logged in the app.

Can merchants tune pricing and claim language?

No. Ch4mber manages pricing, inventory allocation, and core claims policy centrally. Merchants can review the program details and request support.

Do brands need to maintain product weights?

Yes, recommended. Weight-based estimates are more accurate. If weight is missing, the app still works using spend fallback.

Is there an audit trail for reviews?

Yes. Queue, completion, and related evidence are stored at the order level.
