摘要

The 1.5 °C global temperature increase target necessitates the transition to net zero emission in various sectors to mitigate the potential threat of global climate change. Net zero may be achieved through diverse means, but stakeholders tend to favor direct emission cuts over offsetting through carbon credit purchases. However, it is unclear what motivates such preferences. Three experiments (N = 2,215), including one pre-registered, were conducted to unpack public moral evaluations of carbon emission reduction and offsetting. While offsetting gives companies moral credit and credentials, it is seen as hypocritical even when net zero or negative emission was achieved. However, mixing offsetting with reduction alleviates the hypocrisy perception. Such moral evaluations subsequently lead to different attitudinal and behavioral responses among key stakeholders. Our findings highlight that emission offsetting cannot substitute reduction and call for more transparent climate communication.
