Abstract:	Degrowth is gaining scholarly attention as a means of transforming affluent societies, by downscaling production and consumption whilst guaranteeing a good life for all within planetary boundaries, through collectively defined self-limitation. However, little empirical research has investigated communication and framing techniques to translate degrowth's system-level focus into individual consumption decisions and self-limitation practices. There is also little critical reflection on the role of the messenger, that is, how commercial versus non-commercial messengers may effectively promote sufficiency or support the degrowth agenda. In two online experiments and subsequent regression analyses, we explored how framing messages around degrowth versus green growth influenced intentions, values, and behaviors to act more sustainably amongst U. K. millennial respondents (N1 = 969, N2 = 933). In Study 1, comparing the effect of sufficiency-promoting marketing (SPM) messages expressing self-orientation without (green growth) or with (degrowth) limits uncovered little difference in consumption attitudes and behaviors between conditions. SPM appeared ineffective at making degrowth values relevant to individuals or promoting widespread self-limitation, making it incompatible with any degrowth agenda. Study 2 tested whether Degrowth- or Green-Growth-framed communications from a non-commercial messenger affected civic-oriented values and policy support for collective limitations. Green Growth framing garnered higher environmental policy support, whilst Degrowth framing increased the likelihood of choosing degrowth or a-growth positions in the growth-versus-environment debate. These findings suggest degrowth framing inspires values whilst green growth spurs policy support. Further, degrowth messaging focused on system-level problems and solutions based on reductions may disengage individuals from mobilizing for societal change. This research exposes the paradoxical nature of sufficiency-promoting marketing. However, it also reveals potentially counterproductive psychological implications of degrowth messaging that can guide advocates developing communication strategies in non-commercial contexts.
