Behavior Change in Ecuador

Congratulations to our winners!

 Climate change needs behavior change. What people eat, what they buy and what they use contributes directly to climate change. And while human behavior is the root cause of climate change, it can also be the solution…if we use what we know about human behavior and decision-making to help consumers make climate-friendly choices. Solution Search: Climate Change Needs Behavior Change set out to identify and spotlight the best solutions from around the world for motivating individuals, households and communities to adopt climate-friendly behaviors and reduce greenhouse gas emissions. The solutions incorporate one or more core behavior adoption strategies: Emotional appeals, Social incentives, or Choice architecture.From over 200 entrants, our judges narrowed the field to the Top 10 Finalists! Click on the finalists below to learn more about their inspiring climate solution, then vote for your favorite. You could help them win $25,000 and expand the impact of their work to fight climate change. Click here to learn more about the science of behavior change.
