Turn rewards into climate action

Sphere helps banks, merchants and loyalty providers embed high-quality carbon offsetting into existing rewards programs — with low integration effort.

A redemption your customers can feel good about

Customers can redeem loyalty points or cashback to fund verified climate projects, and see the impact inside your mobile app, web portal, marketplace or statement.

Carbon offset through your existing redemption journey

If you already run a rewards program, you can treat carbon offsets as a standard redemption item.

Common patterns

  • Points to offset — Your rewards engine converts points into a monetary value or kg CO₂ equivalent, then calls Sphere to execute the offset.
  • Cashback to climate contribution — Allocate part of cashback to an offset purchase through customer opt-in or a default-on design.
  • Marketplace item — List “Offset my footprint” alongside vouchers and statement credits.

How it works

  • 1. Your app or loyalty engine calculates the redemption value: points to currency or kg CO₂.
  • 2. Your backend calls Sphere’s carbon API to execute the purchase.
  • 3. Sphere returns confirmation and impact data you can display — project, quantity, and certificate or receipt where applicable.
  • 4. You retain a full audit trail for reporting and customer service.

Why it works

  • Low friction — Add a redemption path instead of re-platforming your rewards stack.
  • Choice and trust — Offer curated, verified projects with clear impact metrics.
  • Modular rollout — Start with one project and one redemption flow, then expand.

Cashback programs with climate rewards built in

Sphere also supports new or existing cashback platforms with a configurable cashback or points model — the kind typically used in banking environments.

How it works

  • 1. Base cashback on eligible spend.
  • 2. Tiered benefits by monthly spend, for example Blue, Silver, Gold, Platinum.

Why it works

Alongside a typical cashback rewards program, the same loyalty engine can be tuned to drive climate outcomes. For example:

  • Cashback-to-CO₂ programs.
  • Bonus cashback for “green” categories, partners or sustainable merchants.
  • Rewards that unlock carbon-offset redemptions (earn → redeem).
  • Campaigns that link spend behaviour to measurable impact, such as “Offset your month”.
