Resumen de Climate Change Demands Behavioral Change: What Are the Challenges?

Elke U. Weber

• There is no silver bullet�no single solution to get us to a sustainable climate. There is, however, silver buckshot: a combination of political, technological, economic, and behavioral actions and interventions that will provide the necessary progress towards that goal. Far from being merely additive, behavioral interventions�i.e., changes in the �choice architecture� of environmentally-relevant decisions�have the potential to amplify and multiply the effectiveness of political, technological, and economic tools. Homo sapiens differ from homo economicus in ways that are both challenging and enriching. A more comprehensive understanding of human attention, motivation, judgment, and choice than that provided by the rational-economic model provides entry points for the design of decision environments that allow us�as consumers, citizens, or policy makers�to change our behavior in ways that bring us closer to a sustainable future.
