Ratcheting up the Nationally Determined Contributions (NDCs) to achieve the Paris Agreement goals requires a better understanding of the enablers and barriers behind NDC formulation. However, existing quantitative analyses on the drivers of NDCs from an anthropological perspective are elusive. This study proposes both a conceptual framework and empirical analysis of how cultural values link with the pledged NDCs. The findings show that individualism (IDV) is a significant and robust predictor for the mitigation levels of NDCs, after controlling for affluence level, renewable energy proportion, democracy and other socioeconomic factors. For every 10-point increase in the IDV score (say from the score of Canada to Australia or from the score of Vietnam to Mexico), the committed per-capita emission in 2030 relative to 1990 levels decrease by 14%-22%. However, such a correlation is absent when assessing the mitigation ambitions using various fair benchmarks. This study underscores the necessity of considering more cultural context and nuances in tackling common climate problems, and advocates for developing tailored climate communication strategies to enhance the NDCs.
