  7. 5. Climate change mitigation policies and personal cost: Are young people more willing to bear the cost for a greener tomorrow?

    Master-uppsats, Lunds universitet/Statsvetenskapliga institutionen

    Författare :Sofia Henriks; [2022]
    Nyckelord :Climate change mitigation policies; Low-cost hypothesis theory; Experimental vignette survey; Climate generation gap; Cost-sensitivity; Law and Political Science;

    Sammanfattning : Even as the public awareness and concern about climate change are increasing, and the younger generations are urging for political action, support for more costly and ambitious mitigation policies is not given. The low-cost hypothesis theory provides an explanation for why our concern about climate change fails to translate into supporting policies when the personal cost is high. LÄS MER
