The Cost of Environmental Messaging On Demand For Energy
The Cost of Environmental Messaging On Demand For Energy Efficiency DENA M. GROMET HOWARD KUNREUTHER The Wharton School, University of Pennsylvania RICHARD P. LARRICK Fuqua School of Business, Duke University “Harmony Between Man, Nature And Machine” “Save Energy And Fight Climate Change” 2 VALUES AND CHOICE • Identity-related concerns affect consumer choice (Akerlof & Kranton, 2010; Berger & Heath, 2007, 2008; LeBoeuf et al., 2010; White & Dahl, 2006, 2007) • Choice as a reflection of what one values • Effectiveness of promoting the environment • Likely moderated by political ideology 3 HYPOTHESES AND OVERVIEW • Environmental aspect polarizes energy efficiency • Promoting the environment: • Repels conservatives • Reject energy-efficient choices would have selected otherwise • Study 1: Ideology and Energy Efficiency • Studies 2 and 3: Labels and Choice • Real choice of incandescent vs. fluorescent light bulb (Study 2) • Hypothetical choice of standard vs. hybrid car (Study 3) 4 STUDY 1 • Political ideology à Energy Efficiency • Key determinant: Value placed on emission reduction (Environmental Concern) • Additional aspects of energy efficiency: • Foreign oil dependence reduction (Energy Independence) • Energy cost reduction (Cost) • N = 657 U.S. participants recruited from Clearvoice Gromet, Kunreuther, & Larrick, 2013, PNAS 5 DESIGN (CORRELATIONAL) • Political Ideology (a = .87) • Identify as politically liberal/conservative • Identify with Democrats; Republicans • Read description of energy efficiency • Potential mediators: Valuation • Reducing carbon emissions (Environment; a = .93) • Reducing foreign oil dependence (Energy Independence; a = .83) • Reducing cost of energy use (Cost; a = .79) • Main DV: Favor investment in energy efficiency • Self, Americans, U.S. government, U.S. businesses (a = .83) Gromet, Kunreuther, & Larrick, 2013, PNAS 6 SUPPORT FOR ENERGY EFFICIENCY Favor Investment in Energy Efficiency Political Conservatism -.24*** (.03) Age .004 (.003) Gender (0 = Male; 1 = Female) .13 (.09) Education Level -.02 (.03) Income Level .06 (.05) Constant 5.49*** (0.22) Gromet, Kunreuther, & Larrick, 2013, PNAS 7 PERCEIVED VALUE 7 Carbon vs. Oil: B = -.08, SE = .02, 95% CI = -.12 to -.04 Carbon vs. Cost: B = -.08, SE = .02, 95% CI = -.13 to -.03 6 Perceived Value (1-7) Carbon Emissions Foreign Oil 5 Cost 4 More Liberal (-1 SD) Gromet, Kunreuther, & Larrick, 2013, PNAS More Conservative (+1 SD) 8 DO ENVIRONMENTAL LABELS AFFECT CHOICE? • Environmental Label: Repels conservatives from energy efficient choice • Makes choice about concern for the environment 9 STUDY 2: LIGHT BULBS • Participants (N = 210) given $2 to purchase incandescent (standard) or fluorescent (efficient) • Learned that fluorescent would: • Last for 9000 more hours • Result in a 75% reduction in electricity costs Price: $0.50 Price: $0.50 Price: $1.50 Price: $0.50 PROTECT THE ENVIRONMENT Gromet, Kunreuther, & Larrick, 2013, PNAS 10 BULB CHOICE 1 0.9 0.8 0.7 Predicted Probability of Choosing Fluorescent Bulb 0.6 0.5 0.4 No Label 0.3 Green Label 0.2 0.1 0 -1.5 Liberal -1 -0.5 0 0.5 Political Ideology Composite Gromet, Kunreuther, & Larrick, 2013, PNAS 1 1.5 Conservative 11 ONE ALTERNATIVE EXPLANATION 7 6 5 Incandescent 4 Fluorescent 3 2 1 Function Savings Gromet, Kunreuther, & Larrick, 2013, PNAS Environmental Benefit 12 OTHER MESSAGES THAT AFFECT CHOICE? 13 STUDY 3: HYBRID CAR • Participants (N = 609 adults recruited online) • Choice: Standard vs. Hybrid Car • Hybrid: Better MPG; Higher price • Label: Save The Earth (Environment) vs. No Foreign Oil (Energy Independence) 14 PERCEIVED VALUE 6.5 6 5.5 Perceived Value (1-7) Carbon Emissions 5 Foreign Oil 4.5 4 More Liberal (-1 SD) More Conservative (+1 SD) 15 CAR CHOICE 100 90 80 Percentage Choosing 70 Hybrid Car 60 50 40 Green Label Energy Independence Label 16 SUMMARY • Conservatives less in favor of energy efficiency investment than liberals • Driven by polarization over environmental concerns • Ideology matters to environmental appeals • Leads to rejection of cost-saving energy efficient options • Bridging the ideological gap • Greater trans-ideological agreement about cost and energy independence 17 IMPLICATIONS • Two different strategies • Motivating the environmentally-concerned • Motivating the masses • Motivating the environmentally concerned • ENERGY STAR Program • “Join the movement to protect the climate.” • “You, too, can join the fight against climate change. Become an ENERGY STAR partner today.” • Motivating the masses • One size fits all unlikely to be effective • Need to consider values of different groups 18 19 STUDY 2: LIGHT BULBS • Participants (N = 210) given $2 to purchase incandescent (standard) or fluorescent (efficient) • Learned that fluorescent would: • Last for 9000 more hours • Result in a 75% reduction in electricity costs • Environmental Salience • Purchase of fluorescent came with blank sticker (No Label) or Protect The Environment sticker (Green Label) • Upfront cost • Bulbs either the same price ($0.50) or fluorescent more $ ($1.50) Gromet, Kunreuther, & Larrick, 2013, PNAS 20 VALUE EXPRESSIVENESS OF CHOICE 4 3.5 Value Expressiveness (1-7) 3 2.5 2 No Label Environmental Label 21 ONE ALTERNATIVE EXPLANATION 7 6 5 Environmental Benefit (1-7) 4 3 More Liberal More Conservative 2 1 0 No Label Green Label Incandescent No Label Green Label Fluorescent 22 PERCEIVED VALUE SIMILARITY 6 5 Perceived 4 Similarity (1-7) 3 2 Green Label Energy Independence Label 23
