There is a body of evidence showing public attitudes towards climate change in various countries around the world. In this study, we employ a phone survey in order to assess attitudes towards climate change in Spain and preferences for a green electricity program that reduces CO2 emissions while making electricity more expensive. Results are similar to those obtained in other studies elsewhere, and complement them by showing a strong public support for implementing the green electricity program. In particular, we find that the mean willingness to pay per month and household is about 29.36€ over the current electric bill. Our results also show that younger individuals who live in the Mediterranean region of Spain are more likely to be willing to pay for this green electricity program.
