Social Comparison: The Secret Ingredient To Making Climate Tools Work

Humans are hardwired to follow the herd—and compete within it. We mimic the behavior of those around us and, at the same time, strive to outperform them. These dual drivers of herd behavior and competition can be harnessed to motivate individuals, organizations, and even entire communities to create meaningful environmental change.

Examples of Social Comparison in Action

1. Opower’s Energy Smiley Faces
   Opower sends residents a simple chart in their electricity bills showing how their energy usage compares to their neighbors. A smiley face signals good performance, and a double smiley face rewards exceptional behavior. This small, clever addition has led to noticeable reductions in energy consumption—because no one wants to be the worst neighbor.
2. Greenpeace’s Guide to Greener Electronics
   By ranking major tech companies on their environmental practices, Greenpeace drives competition among corporations to improve their scores. Companies don’t want to be listed as laggards, which motivates real change.
3. Carbon Disclosure Project (CDP)
   The CDP ranks the largest publicly traded companies by their carbon emissions per dollar of revenue. By spotlighting the top and bottom performers, it creates a competitive incentive to lower emissions.

How to Design Effective Comparisons

Social comparison works best when the data is presented visually, making it easy for people to see where they stand. Here’s how to craft a compelling comparison:

1. Make It Tangible
   Use real-world visuals to represent data. For example, show water usage as bottles, barrels, or clouds. Ben & Jerry’s once illustrated that each tub of their ice cream produced two pounds of CO₂ emissions, using a car graphic to drive the point home.
2. Highlight Individual and Group Scores
   Show people their own performance alongside others in a way that emphasizes differences. For instance, compare an individual’s water usage to their neighbors or their district’s recycling rates to a nearby district.
3. Add Emotional Reinforcement
   Avoid the risk of discouraging high performers by reinforcing their success. Adding a smiley face, a badge, or a positive message like “Great job!” helps sustain high performance.

Ideas for Social Comparisons in Sustainability

• Water Usage
  Show daily water usage compared to neighbors or people in other countries. For instance:
  • You: 100 gallons/day
  • Your neighbors: 75 gallons/day
  • Average person in India: 25 gallons/day
• Energy Consumption
  Compare annual household energy use based on household size.
  • Single person: X kWh/year
  • Two-person household: Y kWh/year
  • Three-person household: Z kWh/year
• Food Choices
  Compare the environmental impact of a beef burger versus a veggie burger. Highlight the carbon footprint and water usage of each meal.
• Car Emissions
  Show the pollution from a gas-powered car versus an electric vehicle. Use this to motivate a pledge to switch to an EV.
• District Rankings
  Rank cities or districts based on their waste reduction, energy efficiency, or recycling rates. Publish the rankings to create friendly competition.

The Power of Data and Disclosure

At the heart of social comparison is measurement. Collecting and disclosing data opens the door to gamification techniques like leaderboards, color-coded rankings, and progress bars. Simply making this data visible can drive significant behavior change. When combined with ranking and emotional reinforcement, the results can be transformative.

Why Social Comparison Works

Social comparison taps into three core psychological drivers:\n

1. Herd Behavior: People naturally align their actions with the group.
2. Competitiveness: We’re motivated to outperform others in our social group.
3. Desire for Recognition: Positive feedback reinforces good behavior and builds self-perception as a responsible individual.

These principles make social comparison one of the most effective tools for driving sustainable change.

Making Change Fun and Effective

We don’t have to rely on wishful thinking or overly complex programs to create change. By focusing on data, transparency, and social comparison, we can design strategies that encourage people to act on their own accord. It’s a low-cost, high-impact approach that pushes the “herd” in the right direction.

As we continue to explore the intersection of behavioral psychology and sustainability, the potential for innovation is enormous. With tools like social comparison, we can transform the way people engage with environmental challenges—making it a colorful, competitive, and deeply impactful experience.
