Hey, Climate Leader 👋
You could be accidentally using the least effective way to motivate your community to change

The Evidence

Behavior design is the missing link to effective climate engagement

A colorful quarter-segment rainbow with red, orange, yellow, green, blue, and purple arcs.

Public disclosure of data

The EPA's mandatory disclosure of toxic chemicals caused a 45% reduction in chemical use over five years.

Character animals

Characters that show a happy or sad expression depending on energy performance get a 47% better response than a color or number gauge.

Simple round clock showing 10:30 with orange hands on a beige face and dark brown background.

Real-time data

Real-time displays showing kWh got households to cut energy consumption by 8%.

Money vs CO2:

Showing energy use in terms of CO2 from electricity gets a 16% better response than showing use in kWh amongst Democrat voters.

Two smiling faces, one blue and one orange, with yellow lines indicating a cheerful connection.

Social imitation

Showing households how their energy use compared with their neighbors reduced energy consumption by 6.3% among the highest energy users.

Traffic light with red, yellow, and green lights from top to bottom.

Ambient color

A light that communicates energy consumption using colored LEDs gets people to save 24% more electricity than showing energy use in numerical kWh.

Commitment

Asking people to write down a pledge and posting it publicly increases a person's retention to that commitment by 74%.

Goals

Asking pilots to achieve a specific fuel-saving goal got aircraft to reduce fuel use by 12%.

Geographic granularity

Comparing people of smaller and more similar groups, such as house vs house, saved 34% more energy than when shown grouping many residences.

Block leader programs

Meta research shows that neighbor block leader programs are more influential than any other mechanism at encouraging conservation behavior.

Guilt vs pride

Showing people their environmental performance is below average (guilt) gets a better response than showing people they perform above average (pride).

Meet Your Host,
Katie Patrick

Environmental Engineer, Author, Podcast Host, TEDx Speaker, and Chief Action Designer at Hello World Labs.

Hello, Green Leader 👋🌱,

Do you need to persuade your community to sign up and take action? I can help. I've spent 20 years creating:

🌈 Engagement tools for big organizations like UNEP, NASA, Stanford, and Google.

📊 Technical dashboards for commercial building portfolios.

🏆 Easy low-tech gamification tools for grass-roots environmental groups.

📧 Funnel systems that have signed up over 100k people to join sustainability causes.

I wrote the world's first book on environmental behavior design and gamification, How to Save the World: How to Make Changing the World the Greatest Game Ever Played – now taught at Harvard University's Sustainable MBA program.

Having graduated from Environmental-Civil Engineering and working on some of the world’s first platinum-LEED-certified buildings, my approach is always evidence-based and quantitative (while still being fun and creative), building from core metrics of feedback loops of environmental data.
