Climate change mitigation and psychology

Climate change mitigation means to reduce energy consumption

the prime strategy: technological efficiency increases

doesn’t work because of rebound

reduction of energy consumption is a psychological problem

common approaches (incentives) don’t work

the problem substantially different from other environmental issues

What really has to be done?

strategies of sustainable

devleopment

efficiency

sufficiency

consistency

the three strategies of sustainable development according to the Brundtland report (WCED, 1987) sustainable development is possible, if and only if all

three strategies are pursued

Consistencyreintegration of the industrial metabolism into natural processes or separation of the metabolism from the environment

Efficiencyderived from an input’s ratio to its utility in respect of a certain measure

Sufficiencyself-limitation, especially with regard to (materialistic) consumption

efficiency increase cheaper production higher profit

green image higher sales

economic growth policy support

more efficient behavior fulfillment of more goals

• reduction greenhouse gas emission by 20%

• share of renewable energies above 20%

• reduction of primary energy consumption by 20%

all strategies depend on efficiency increases

consumption per capita kWh/a +23%

consumption per dish washer kWh/a -19%

Difference to previous environmental problem

single behaviors can be changed effectively

BUT: what do people do with savings from efficiency gains (and other sufficient behaviors)

spend otherwise e.g., for a nice vacation

Why are you listening to this talk?

Everybody has and endless number ofdesires, goals and motives

How can you attain more of them?

By being more efficient (with technology)

efficient technology• more effective goal attainment• functional, facilitates everyday life• attain our goals with less effort and faster• more goals can be attained

efficiency increase is prime strategy of evolution

psychological explanation of unrestrained consumption• the purpose of cars, fridges, and houses is not to save energy• they are means to satisfy personal ends• technology serves personal goals (extrinsic) climate change mitigation is no prime goal of most individuals fulfilling more personal desire and motives IS prime goal

*intrinsic motivation: motive to reduce environmental burden / mitigate climate change extrinsic motivation: any other motive

most effective programs: extrinsic behavioral managementmain focus on enticements / incentives

• financial

• social

*intrinsic motivation: motive to reduce environmental burden / mitigate climate change extrinsic motivation: any other motive

Example: AIM of the European Union until 2020

Agenda 20-20-20 EU 2008

common practice -> change behavior difficulty (with extrinsic motives)

social enticements / incentives

benefits grounded in people's social motives e.g.:

• status motives

• social norms (descriptive and injunctive)

• publicly made promises

financial enticements / incentives

e.g., providing free access to products or services, fees, rebates, subsidies …

financial enticements / incentive

example: lamps

price (e.g., subsidize energy efficient light bulbs)

money savings for the individual

solution:change situational costs

problem:low acceptance of energy efficient lamps

effective change of single behaviors

worked for most previous environmental issues (e.g. ozone layer depletion)

BUT:

impossible to change all relevant behaviors

savings in terms of time and money

social and financial enticements / incentives

additional consumption (rebound)

no reduction in overall energy consumption

no climate change mitigation
