Behavioral science for climate action
Caring about the planet is common. Acting on it is a design problem.
We run controlled experiments on the moments where good intentions stall: a checkout, a default, a prompt. We find the small changes that turn intent into action, then hand the evidence to companies and policymakers who can scale it.
When an airline asked travelers to chip in for reforestation, the ones who declined still preferred that airline. The ask built goodwill, and giving more than doubled.
From two airline booking-flow studies →What we do
We test how people actually behave, then publish, brief, and build on what we find.
Research
Controlled experiments on how people make environmental decisions, published with open data on the Open Science Framework.

We asked travelers to give at checkout. Most did.
Redesigning the In-Booking Donation Flow: Evidence from Two Airline Studies
We rebuilt the donation step in two major airlines' booking flows and tested it with real money. Giving more than doubled, and the airlines paid no cost in brand favorability or booking intent.
Consumer Support for Environmental Restoration Projects
In a controlled experiment, travelers were offered a one-tap reforestation contribution at flight checkout. Most gave their own money, and even the travelers who declined preferred the platform that asked.
SolarSoiled: Finding the Panels That Need Cleaning
A machine learning system that detects rooftop solar in public aerial imagery and scores each array's soiling risk from weather and air quality data, so cleaning happens where energy is actually being lost.
