The aim of this paper is to study the impact of emotional states on monetary donations to environmentally friendly causes regarding Environmental Non-Governmental Organisation (ENGOs) fundraising. We design a three-stage laboratory experiment. In the first stage, we ask participants to reveal their ecological and environmental preferences through the New Environmental Paradigm (NEP) Scale. In the second stage, emotions are induced in the participants. In the third stage, participants play a dictator game in which the recipient is an ENGO. We show that emotional states do not prompt donations themselves, but that certain negative emotional states (“Shame”) can decrease the amount donated.
