Public Perceptions: Climate Change & Environment National Public Opinion Polls:
82% - Climate change is real (60% caused by human activities)1.
65% - concerned “a great deal” or “a fair amount” about climate change2.
53% - Climate change is one of the most serious long-term issues facing our country3.
Middle Tennessee4: 67% are “very concerned” about the environment. 43% believe air pollution is harmful to their health.

Pro-Environmental Behavior Behaviors changed because of air pollution
(Middle Tennessee): Carpooled - 1% Used mass transit - <1% Limited driving - 1% Reduced energy use - 1%

Overcoming Barriers to Behavior Change
Provide usable information Make behavior change easier Promote efficacy Use Social Norms

Lack of “Usable” InformationMisperceptions often lead us to the “wrong” actions.
We overestimate the energy used by things we see (lights) and underestimate the things we don’t (hot water heater, furnace).
>80% of Americans hold inaccurate beliefs about idling1: It is better to idle for ___ in order to:
“Save gas” = 4.7 minutes “Prevent pollution” = 3.6 minutes “Prevent vehicle wear” = 5.7 minutes
Information is most effective for easy-to-change behaviors

Presenting InformationInformation is most effective when it is:
From a credible source ‘State Regulatory Agency’ vs. ‘Local Utility’ Seek out endorsements
Vivid “30 inches of cracks” vs. “a hole the size of a basketball”
Meaningful Making the abstract concrete
2000 kwh = “enough energy to power the average home for 6 weeks”.
“If everyone lived like you we would need 2.1 planets to support global consumption”
Example - ‘Black Balloons Commercial’ http://www.youtube.com/watch?v=vZLDPEQzlck
Provide specific calls to action

Make Behavior Change Easier We are less likely to perform behaviors that require:
More steps More time and effort More mental energy (e.g., memory, attention)
Examples The single biggest determining factor in whether a person recycles if
the availability of curbside recycling. Organ Donation (opt-in vs. opt-out)
Consider default settings: Hot water heaters Energy saving settings
(computers, monitors)
Johnson & Goldstein, 2003

Make Behavior Change Easier
External Barrier The Big Ones The Smaller Ones
Access to mass transit Increase routes and frequency Organize carpool networks within organizations
Cost of efficiency upgrades Tax incentives/loans/rebates Allow cost of upgrades to be paid for from savings in electricity bills
Difficulty remembering to turn off lights (particularly in organizational settings)
Install motion-sensor lighting Post reminders on light switches
Time/effort required to weatherize/insulate home
Provide free/subsidized service Energy auditor arranges for the services at the time of audit.
Remembering to maintain proper tire inflation
Service offered at time of fill-up
Reminders posted at gas stations

Promoting Efficacy We are less motivated to engage in behaviors that we feel are ineffective. Particularly important for frequent & easy to change
behaviors. Promoting Efficacy:
Message framing Stress the connection between behaviors and outcomes.
Feedback Feedback meters associated with 5 to 60% reduction in energy use. Continuous feedback is most effective (feedback meters) Periodic feedback is better than no feedback (public announcements)

Vanderbilt’s ThinkOne Campaign
In September of 2008, the Undergraduate Admissions Building used about 65,600 kilowatt hours (kWh) of electricity. This is moving in the right direction, as it is 12% better than average for your building! However, it is still 2,600 kWh from reaching your goal…

Using Social Influence Social Norms:
Pressure to comply (social approval) Pressure to conform (popularity, fitting in)
We often change our behavior to accommodate social norms. 75% of participants gave an obviously wrong answer (Asch, 1951).

Using Social Norms Message Framing:
Sequoia National Park (Winter et al., 2000):
“Many past visitors have gone off the established paths, changing the natural state of the Sequoias and vegetation in this park”
“Please don't go off the established paths and trails in order to protect the Sequoias and natural vegetation in this park”

Using Social Norms Identify Early Adopters:
Water Conservation Study (Aronson & O’Leary, 1982)
“Conserve water: 1. Wet down. 2. Water off. 3. Soap. 4. Rinse.”

How to build an effective program1. Set goals2. Identify barriers3. Plan and Implement 4. Evaluate5. Revise and refine
![Page 16: 1 Effective Communication & Behavior Change Seminar for Environmental Leaders Sponsored by The Solar Valley Coalition October 28, 2008 Amanda Carrico amanda.r.carrico@vanderbilt.edu.](https://reader030.fdocuments.in/reader030/viewer/2022032701/56649c7f5503460f94935d9b/html5/thumbnails/16.jpg)
16
Set Goals Long-term goals
Mission statement Short-term goals
Create specific near-term objectives Quantify objectives
15% decrease in campus electricity use (ThinkOne) 10% increase in carpooling
Identify behaviors that will achieve those objectives
Conservation behavior (lighting, heating and cooling, appliance use)

17
Identify Barriers Understand what may prevent an
individual from engaging in the target behavior. Literature Search Focus Groups Surveys (Needs Assessment)
How often do you engage in this behavior? What helps you to engage in this behavior? What prevents you from engaging in this behavior?
Observation
![Page 18: 1 Effective Communication & Behavior Change Seminar for Environmental Leaders Sponsored by The Solar Valley Coalition October 28, 2008 Amanda Carrico amanda.r.carrico@vanderbilt.edu.](https://reader030.fdocuments.in/reader030/viewer/2022032701/56649c7f5503460f94935d9b/html5/thumbnails/18.jpg)

Create a Plan Determine which behavior change
techniques are at available. Make concrete steps for how to achieve
goals. Create a logic/process model to outline
steps required to implement plan and for the plan to be effective

Evaluate No intervention is complete without an evaluation Measure:
Behavior Exposure to intervention Reactions to intervention (negative and positive) Unexpected consequences
Printed materials not being recycled Turning off lights leads to safety concerns
Tools for evaluation: Surveys Observation Focus groups Comment pages/Community Forums (website)

Revise & Refine Allow enough flexibility to revise and
refine your program!!
