Sustainability and profitability aren't in conflict
Our research shows that customers prefer platforms that make giving easy, even when they choose not to give. We help companies build that preference into their products.

Case study: travel industry
The checkout contribution that customers rewarded
In our controlled study, an online travel agency added a one-tap reforestation contribution at checkout. 69% of participants gave their own money. 75%preferred the platform that offered the option, including people who didn't donate, and many were willing to book there even at higher ticket prices. The option cost the platform nothing in perception or intent to book again.
Implementation is light. It takes a basic integration into the checkout and payment flow, and Rainforest Trust is already set up to receive the contributions. Even a conservative 5% opt-in rate generates real conservation impact at booking-platform scale.
We have since tested redesigned donation flows inside two major airlines' booking experiences with real money on the line. Giving more than doubled, at no cost to brand favorability or booking intent. Read those findings.

How we work
How an engagement works
Diagnose
We map the decision moments in your product where environmental intent currently goes nowhere: checkout, onboarding, renewals, defaults.
Design
We design interventions grounded in published evidence and sized to your engineering reality. Most ship within a sprint.
Measure
We instrument the rollout as an experiment, so you learn the real opt-in rate, the revenue effect, and the environmental impact rather than taking a vendor's word for it.
